New lenses – facts, rumours and speculation
20th A new adapter for fitting EF lenses to a GFX 50S [Techart news post]
17th A while ago I reviewed the rather nice Sigma 12-24mm F4 DG HSM Art lens … well, I had a second chance to try it out, but with an emphasis on its use for architectural photography. I’ve written up an article exploring the problems and challenges of using the Sigma 12-14mm for architecture.
It’s partly aimed at being a tutorial about making effective use of ultra wide lenses. Hopefully it makes the point that you can get some very striking images without buildings falling over, but that you need to think very seriously about composition. [click to enlarge]
16th The Tamron 100-400 is announced (due by the end of the year): [B&H link]
100-400mm F/4.5-6.3 Di VC USD (Model A035)
September 15, 2017 – Commack, New York – Tamron USA, Inc. announces the development of a new ultra-telephoto 100-400mm F/4.5-6.3 Di VC USD zoom lens (Model A035) for full-frame DSLR cameras. The advanced optical design of Model A035 includes 3 LD (Low Dispersion) lens elements for greater aberration reduction and Tamron’s original eBAND Coating for superior anti-reflection performance.
At 39.3 oz., the new lens is the lightest weight in its class and features magnesium material in key areas of the lens barrel to improve weight reduction, strength and portability.
The Model A035 delivers fast and precise autofocus performance and consistently powerful VC (Vibration Compensation) benefits thanks to the high-speed Dual MPU (Micro-Processing Unit) control system that is found in the latest Tamron lens models.
Model A035 is fully compatible with Tamron’s 1.4X teleconverter and the Tamron TAP-in ConsoleTM that enables lens customizations for focus adjustments, VC mechanism adjustments and more. Additionally, an Arca Swiss compatible tripod mount is available as an optional accessory.
This combination of features and optional accessories join to create a lens that photographers everywhere will enjoy using in various shooting situations, including low-light conditions that require handheld operation as well as those where convenient attachment to a tripod is preferred.
 Among 100-400mm F/4.5-6.3 lenses for 35mm full-frame DSLR cameras (As of September 15, 2017; Tamron)
- 3 LD (Low Dispersion) lens elements effectively compensate for axial chromatic aberrations, a potential issue for ultra-telephoto lenses, and other various aberrations.
- eBAND (Extended Bandwidth & Angular-Dependency) Coating, with superior anti-reflection performance to eliminate flare and ghosting, provides flawless, crystal clear images.
- High-speed Dual MPU (Micro-Processing Unit) control system delivers quick and highly responsive autofocus performance and outstanding vibration compensation.
- Lightest weight (39.3 oz.) lens in the ultra-telephoto zoom lens category.
- Optional accessory tripod mount is Arca Swiss-compatible.
- MOD (Minimum Object Distance) of 59″ and maximum magnification ratio of 1:3.6
- Moisture-Resistant Construction and Fluorine Coating for weather protection
- Fully compatible with 1.4X teleconverter and TAP-in Console
15th A Japanese patent covers the Nikon PC-E 19mm tilt shift lens.
Canon keeps plugging away at its DO technology (see Jan 31st and July 5th below) – a 600/4 DO IS appeared at a Canon expo, but there are suggestions [CR] that more will appear in time for next year’s photokina in September.
Two Nikon Japanese lens patents [HL] cover 24/1.8 lenses for full frame and APS-C size sensors. The short back focus distances suggesting both are for mirrorless cameras. [Direct link to Japanese patent – note that you cannot use Google translate]
12th A new 100-400 mm f/4.5 – 6.3 Di VC USD (Model A 035 Can/Nik mount) is said to be on its way from Tamron [Nok]
August 30th I’ve updated the tilt tables in my ‘Focusing tilted lenses‘ article to include the new TS-E lenses.
A service advisory has been published in the US for the 50/1.4
Service Notice: EF 50mm f/1.4 USM

29th Canon launches 3 TS-E and an 85mm lens
28th Yes please, one of each of them… Some UK prices suggested [Nok] for lenses
“EF 85 mm is 1569 pounds, TS-E lenses are 2499 pounds each”
With the renewed interest in T/S lenses, I’m reminded of a US patent from IBM in 2015 for auto tilt/shift [USPTO] where you’d select a couple of images points and the camera does the rest. I doubt that the new lenses will have encoders for tilt and shift to recorded…
26th Wondering about macro and tilt/shift lenses? I’ve been doing a few experiments with tilted lenses and extension tubes…
25th More Canon lens images. The 135mm has a max tilt of 10 degrees and the 50mm 8 degrees (as the TS-E24 mkII)
Details of Canon’s new lenses [nok]
I note a different style of marking to show tilt – no indication here as to whether the maximum tilt has been increased from the current models. Also, the smallest aperture seems to have moved up to f/45.
The design of the lenses suggests that the TS-E mount bracket [PPL TSE adapter] I tested a while ago on the TS-E17 and TS-E24mm mk2 will work with the new lenses

17th A Canon Japanese patent shows a bayonet ‘cinema’ mount version of the EF mount – the patent shows both sides of the mount. Looking at the drawings, it seems that it’s an EF mount that does not require the whole lens to be rotated to lock in place, just a lever on the lens mount (click images to enlarge).
[Note that a second Canon patent for curved sensors was also published – some sites seem to have conflated the two]
Detail of the lens mount
Fitted to camera
Original info [HiL]
15th No dates yet for the new lenses…
I’m still wondering if I really want the new TS-E50mm 2.8L macro lens when it comes? – The TS-E17 and TS-E24 are fixtures in my camera bag for architectural and interior work, but I don’t use ~50mm that often (but do see some testing of a 55mm shift lens I did this morning).
The optical performance of the TS-E 45mm wasn’t really what put me off getting one – more how much I would use it. I’ve a collection of Mamiya 645 lenses and a M645->EF shift adapter for 35/55/85mm which covers longer views and a TS-E90 for product shots – so a TS-E135 might be a better choice (new lenses need to pay for themselves – we’re not that flush ;-)
14th More 85mm details from CR
- Minimum focusing distance : 85cm / 2.78′ |EF 85mm f/1.2L II minimum focusing distance is 95cm / 3.12′
- Weight: 950g / 33.5oz | EF 85mm f/1.2L II weighs 1025g / 36.16oz
- Filter size: 77mm | EF 85mm f/1.2L II filter thread is 72mm
- Max diameter 88.6mm / 3.48″ | EF 85mm f/1.2L II is 91.4mm / 3.6″
- Length: 105.4mm / 4.15″ | EF 85mm f/1.2L II is 83.8mm / 3.3″
13th A few more specs for the 85/1.4L IS add ‘fluorine coating’, 9 aperture blades and 1 moulded aspheric element to the list (no weight/price) [CR]
12th More info [Nok] about upcoming lenses confirms the three TS-E lenses and adds
- Lens hood “ET – 83E” “ET – 88” “ES – 84”
- Macro twin light “MT-26EX”
11th Venus Lens announce the Laowa 15mm Zero-D f/2 lens for Sony E mount [news item]
A Nikon patent covers a lens adapter for a mirrorless camera, and adds a pellicle mirror and phase detect sensor [Mirrorless page]
10th Sigma note some difficulties with some of their lenses and some recent Canon cameras:
When the lenses listed below are used on EOS 6D Mark II, EOS 77D, EOS Rebel T7i, EOS Rebel SL2 and the “Lens aberration correction” function on the camera is set to “Enable” for Live View shooting, an error would occur.
- SIGMA 30mm F1.4 DC HSM | Art
- SIGMA 35mm F1.4 DG HSM | Art
- SIGMA 30mm F1.4 EX DC HSM
- SIGMA 50mm F1.4 EX DG HSM
- SIGMA 85mm F1.4 EX DG HSM
Usage Notice for customers who are using EOS mount SIGMA lenses on CANON cameras
When using the SIGMA lenses for CANON, “Peripheral illumination correction”, “Chromatic aberration correction”, “Diffraction correction” as well as “Distortion correction” from the “Lens aberration correction” function of the camera are not supported. Therefore, we recommend you to set them to “Disable”.
If those functions are set to “Enable”, the performance of the lenses may not be accurate.
9th The specs [CR] for the lenses change a bit
- TS-E 50mm f/2.8L Macro (0.5x)
- TS-E 90mm f/2.8L Macro (0.5x)
- TS-E 135mm f/4L Macro
- Canon EF 85mm f/1.4L IS USM
85mm is same styling as the EF 35mm f/1.4L II. Fast AF and 4 stop IS.
The 135/4 is much more likely to accept the flash support ring of the MT-20EX (a flash I use with the TS-E90/2.8 and MP-E65/2.8)
8th Some more details of upcoming Canon lenses [CR] and a photo of one seen out in the wild
- Canon EF 85mm f/1.4L IS | Canon TS-E 45mm f/2.8L
- Canon TS-E 90mm f/2.8L | Canon TS-E 135mm f/2.8L Macro ?
If you were wondering how tilt at 135mm works, here’s a copy of my tilt tables including 135mm (what this means) although using tilt for macro it’s often more helpful to use this iterative focus technique for tilted lenses.
This is supposedly one of the lenses (45mm?)
3rd Three new lenses on the way (at the end of August??) are said to be tilt/shift lenses [CR]
I use these lenses a lot (links are to reviews), so this could be an expensive announcement ;-)
As a note of caution, I’d note that in the recent rumours about lenses it was suggested that some new lenses were being made in Malaysia. Canon makes all its top lenses back in Japan.
31st Useful review of the Sigma 24-70mm f/2.8 DG OS HSM Art Series Lens [LR]
20th Canon US patent for a 50 f/4.5 – 900 f/7 [USPTO]
The size of the front element groups suggest significant cost – the sort of lens definitely in the cine range…
A Japanese Nikon patent (2017-125904) for a 35mm lens with curved sensor appears (f/2 | 35 deg half angle| full frame 21mm image height) – see also main mirrorless page
There are several variations on the design.
It’s world cup year in 2018, so expect updates to long white lenses – two predicted at [CR] – Canon showed a 600/4 DO lens back in 2015 and the long lenses are not quick to get into production (making big bits of glass is not something you just decide to do in a few weeks).
19th Interesting look at the Sigma 14/1.8 for astrophotography [DPR]
17th Interesting interview with Sigma CEO [16 mins]
14th The possible 85/1.4 IS L gets a bit closer with a mention in product certification info [main rumour page] – that and a few more likely kit zoom versions
12th Lensrentals review of Sigma 14/1.8 sharpness [LR]
11th Nikon launch a new AF-P NIKKOR 70–300mm f/4.5-5.6E ED VR – details on main Nikon page.
10th Venus lens announce a shift adapter for using ultra-wide lenses (manual only – no electronics) such as the 12mm/2.8 I reviewed a while ago as a shift lens on Sony E mount. Acting as a teleconverter, it expands the image circle (making it 17mm/4) [Full details inc. MTF and pics]
5th In a further development of their Diffractive Optics patents, a Canon US patent  addresses the problems of the resin layer peeling off the glass at the edges after a while (especially if it’s warm) – this follows from the info (Jan 31st) below.
Mentioned a while ago, an EF 85mm f/1.4L IS is still ‘pending’ – maybe for the autumn [CR]
3rd Rear gel filters for wide lenses seem to be making a comeback with more info from Irix about theirs (due Aug.) – see also the Sigma one a few days ago
|Dimensions:||29 x 29 mm||29 x 29 mm||29 x 29 mm|
|Thickness:||0.1 mm||0.1 mm||0.1 mm|
|Number of sheets:||5 pcs||5 pcs||5 pcs|
I experimented a few times in the past with the filter holder on my EF14/2.8L mk2 but just never found a use – the EF11-24 also has such a filter socket – the Irix set has an RRP of 8 euros so hardly expensive to experiment with.
30th Tamron officially announces the SP 24-70MM F/2.8 DI VC USD G2
Full specs (MTF charts etc) are on our Tamron 24-70 product info page
June 30, 2017, Saitama, Japan – Tamron Co., Ltd. (President & CEO: Shiro Ajisaka), a leading manufacturer of optics for diverse applications, announces the launch of a new high-speed zoom lens, SP 24-70mm F/2.8 Di VC USD G2 (Model A032), for full-frame DSLR cameras. Model A032 is a fast F/2.8 zoom that achieves top-level image quality. The new Dual MPU (Micro Processing Units) provide rapid autofocusing with improved accuracy and the highest vibration compensation performance of any lens in its class*2 (CIPA level of 5 stops*1). The use of specialised, high quality glass materials (offering greater optical transmittance) for the lens element assures superior colour reproduction and greater sharpness, while the application of Tamron’s exclusive nanotechnology-based eBAND Coating substantially curbs the ghosting and flare that are prone to occur in backlit photography, successfully improving the overall optical performance of the lens. Additionally, model A032 provides the added conveniences of protective Fluorine Coating, Moisture-Resistant Construction and a locking lens hood. Photographers can use this new high-speed zoom lens for wide-ranging purposes, including landscape, portrait, news, travel and many others.
Sigma announces a gel filter holder for the 14mm f/1.8 DG HSM (EF fit only)
The lens itself is due to ship in July
23rd A bit late, but the patent for the EF11-24 F4L appears [USPTO]
Remember patents are not written for ease of reading – one for connoisseurs of lens design ;-)
The latest two Sigma Art DSLR lenses are now available for pre-order:

A 30mm/1.8 basic EF-S prime would be an interesting option.
3rd A Tamron Japanese patent (2017-97198) for a 20mm f/1.8 lens has been published.
30th There is an image sample gallery for the Canon EF-S 35mm f/2.8 IS STM Macro [DPR]
A Japanese Canon lens patent (JP-A-2017-090772) has a built in teleconverter option in a zoom lens. Nothing new there, but that it’s at the wide end…

Nikon have three new lenses on the way including an 8-15 zoom fisheye
More on the Nikon rumours page
25th A Canon US patent for a linear USM motor for lenses.
Some Canon patent info appears [via CR] for a longer T/S lens – probably a 90mm replacement rather than the 45mm
The patent has examples for 90/2.8 | 125/4 | 130/4 lenses
18th Sigma announces firmware updates for 4 EF mount lenses (note that you will need the USB dock to update the lenses)
- SIGMA 24-105mm F4 DG OS HSM | Art CANON
- SIGMA 17-70mm F2.8-4 DC MACRO OS HSM | Contemporary CANON
- SIGMA 18-200mm F3.5-6.3 DC MACRO OS HSM | Contemporary CANON
- SIGMA 18-300mm F3.5-6.3 DC MACRO OS HSM | Contemporary CANON
Sony add a 16-35mm f2.8 and 12-24 f4 to the FE lineup [Sony page]
14th A few years ago there was a lot of speculation over whether a replacement for the EF24-70 2.8L would have IS. Obviously Canon can make a version with IS, but at the time it was suggested that IS would make the lens a bit too bulky/heavy.
This might be back on the table [CR] but before reaching for your wallet, it’s worth noting that Canon has an awful lot of ‘active development’ going on at any one time and the time between lens rumour and announcement is even more unpredictable than cameras, where you do at least have a timeline to look at.
We’ve had regular suggestions about updates to the TS-E 45 and TS-E 90 for years now and apart from the odd patent relating to movements, not a lot. My own feeling is that there won’t be any new TS-E lenses until a new ‘smarter’ movements mechanism is ready to go (see patent from January 9th below)
8th The link below might well have been posted too soon – it’s been removed…
7th Canon in the Philippines are reporting a Service Notice for the EF 24-105mm f/4L IS II USM Lens related to AF performance [Canon Ph – May 5th]
Phenomenon: At the wide-angle end, focus is not achieved properly when a peripheral AF points are selected, regardless of the AF area selection mode.
Affected Lenses: If the first two digits in the serial number of your lens are ”48”, ”49”, ”50” or ”51”, then your lens MAY POSSIBLY be affected.
There is a form on the Canon info page, where you can enter the serial number to check if the lens is an affected one. I note that this form is currently only on the Canon site for the Philippines
4th Canon’s EF-M mount differs in quite a few ways from EF and EF-S. Most obvious is the physical size difference.
The new EF-M lenses have 9 connection pads to connect to the pins in the camera.
The lens uses the same serial interface and clock lines for communication.
The DTEF line is used to identify lens type, probably a simple resistor, since the DTEF_IN input is a 10 bit A/D convertor.
29th I’ve just finished a review of the Samyang/Rokinon SP/XP 14mm f/2.4 lens – excellent quality that even pips my EF11-24 F4L in a few respects. A big step up from the Samyang 14mm f2.8 I reviewed a few years ago.
Laowa announce more details of their 7.5mm rectilinear lens for M43 (Keith’s Laowa/Venus reviews]
Anhui China, Apr 28, 2017 – Venus Optics, the camera lenses manufacturer who had previously launched a number of unique Laowa camera lenses, is proud to announce the world’s widest rectilinear f/2 lens for Micro Four Thirds cameras, Laowa 7.5mm f/2 MFT.
The Laowa 7.5mm f/2 MFT is currently the widest f/2 rectilinear lens ever designed for Micro Four Thirds Cameras. It is an ultra-wide & ultra-fast prime lens with a 35mm equivalent focal length of 15mm. Despite the extreme specifications, Venus Optics has successfully minimized the weight of the lens to less than 200g (0.44 pounds) and 55mm long. This compact and light lens comprises of 13 elements in 9 groups with 2 pcs of aspherical elements and 3 pcs of Extra-low dispersion elements. This optical design successfully minimizes the distortion and chromatic aberrations to its lowest but at the same time, delivers a superb optical performance from corners to corners.
The extreme 110° angle of view and ultra-fast f/2 aperture allows photographers to create impressive astro-photography shots with ease. It also gives photographers a fast and wide-angle option for landscape photography and low-light shooting. The lens is designed with a 46mm filter thread which can gives additional portability for screw-in filters.
Venus Optics also introduce a lightweight version for this lens and controlled the weight to merely 150g. The feather-light weight opens up a new opportunity for photographers and pilots to shoot wider footage with gimbals and drones.
Availability The Laowa 7.5mm f/2 MFT is currently available to pre-order in the official website of Venus Optics (http://www.venuslens.net/) and their authorized resellers. It comes with 2 colors, Black and Silver. Recommended Retail Price in US (without tax) is USD 499/pc for standard version and USD 519/pc for Lightweight version. Pricing may vary in different countries.
One to get the collectors drooling – The Canon 300/1.8 lens, as used for horse racing photo finish recording. Lots more pics [PT]
21st I’m just finishing up some testing of the rather nice Samyang XP 14mm f/2.4 lens and see that before long we should see a USB ‘dock’ device (‘lens station’) for updating firmware [PR]
17th The NAB show in the US should see a CN-E 70-200 cine lens announced.
9th The next EF lens ‘due’ is an 85mm f/1.4L [CR] – no specs or dates other than late Q2/Q3
Full lens details (Specs/Samples/MTF) at the EF-S 35mm f/2.8 Macro IS STM listing at EFLens.com
MELVILLE, N.Y., April 6, 2017 – Compact and lightweight, the new Canon EF-S 35mm f/2.8 Macro IS STM, announced today by Canon U.S.A., Inc., a leader in digital imaging solutions, is the widest-angle Macro offering in Canon’s popular EF-S lens series. The new lens is designed to help both entry-level and advanced amateur DSLR photographers discover the incredible possibilities of macro photography. Capable of capturing close-up subjects with incredible detail, Canon’s new EF-S macro lens is also the first in the series to feature built-in Macro Lites that allow users to control lighting with ease.
5th A Canon US patent [USPTO] shows how to selectively apply aluminium to diffractive lens elements and massively reduce light scattering.
Aluminium is deposited onto the diffractive element at an angle, so as to build up a denser layer on the grating walls (blue) than the front surface (yellow). The aluminium layer is then partially oxidised, converting the front surface coating to a transparent layer of alumina (Al2O3), but leaving the denser (and opaque) aluminium in place on the side walls.
Light going (‘the wrong way’) through the grating walls is a major contributor to flare, and in the patent, a test example reduced this by 8 times.
4th A second photo of the Canon 35mm macro appears [Nok]
3rd Specs for the EF-S 35 mm F 2.8 Macro IS STM lens appear [Nok]
- Lens construction: 6 groups 10 elements (1x glass moulded aspheric lens)

- Shortest shooting distance: 0.13 m (working distance 3 cm)
- Maximum magnification: 1:1
- Image stabilisation: ~4 steps
- Filter diameter: 49 mm (with lens hood ES-27 installed)
- Size: 55.8 x 69.2 mm
- Weight: Approximately 190 g
- Built-in macro light
- Hybrid IS
- Lead screw type STM
31st A new lens to test… I’ve just been sent the new Samyang XP 14mm f/2.4 to try out on my 5Ds. Some first impressions are that it’s very sharp and the distortions are easily controllable – low CA and barrel distortion of a less complex type than the old Samyang 14mm f/2.8 I reviewed a few years ago.
One quick sample wide open shows that you can get OOF areas at f/2.4… (click to enlarge)
Watch out for internet story inflation as a French story about a visit to Canon’s lens factory runs through multiple languages.
The line that will be picked up is “Without being able to tell you more, we are developing a new technology that will bring real added value and will allow to take a new type of photo.”
Obviously, this is a translation from Japanese to French to English, so could mean just about anything or nothing much…
I did like the cutaway of the Canon 11-24 – which reminded me why I was thinking it was so heavy when using it yesterday ;-)
22nd The upcoming EF-S 35mm f/2.8 M STM could feature built in LED lighting [CR]
One of the new lenses from Nikon this year is said to be an ultra wide or fisheye (reasonable, given how good the Canon EF8-15 and EF11-24 are) [NR]
A quick look at the Laowa 25mm f/2.8 2.5x – 5x Macro (development sample)
Only a test sample, but I got to try it out on my 5Ds – The lens almost doubles in length as you extend it to 5x
This is a development lens so it’s not fair to post any sample images, but as someone using the MP-E65mm for macro work I’m very interested to see how it performs.
So, I suppose in the tradition of some photo web sites, I should trumpet this as a ‘Hands-on review’ – no, probably not… ;-)
Here it is again with the 24mm relay lens at the back, with its waterproof cover and LED light unit
My last day talking ay printing at ‘The Photography Show‘ in Birmingham, so a bit more of a chance to look round at some of the lenses on show…
14th Oh, not a wide angle lens then… Suggestions [CR] that the new lens is a ‘EF-S 35mm f/2.8 M IS STM’
– no idea yet what the ‘M’ designation means (not quite ‘L’ ?)
11th It seems that Canon is getting a bit more serious with the EF-S mount and announcing a new wide prime lens early in April [CR] – the focal length is not yet known for sure
I’ve still got our 100D (Karen loves the size) and I’ve always found its lack of small wide lens a disincentive to take it with me more often – the EF-S 10-18mm [review] is a fairly good lens, but an 8mm or even 10mm would be a good option for the Canon crop sensor cameras – it was lack of wide angle lenses that made me pick the full frame 1Ds when I seriously switched to digital back in 2004.
In Nikon land, there are (very) vague suggestions that this year will see 5 new lenses [NR]
7th A few more for that CPS exclusion list: Extender EF1.4x II, Extender EF2x II, Battery Grip BG-E2
I’m sure some people lap this sort of stuff up, but apart from technical curiosity, it left me stone cold – no feel for what the lens was really like at all. I’m hoping to expand our lens reviews this year and they will be in the style of the Sigma one… there are more than enough lifeless tables of data already so I’ll not be adding to them ;-)
A message from CPS Europe notes three items removed from CPS coverage, due to being classed ‘no longer serviceable’ – Ah, time to take care with my 70-200 then
- EOS 50D
- EF 70-200mm f/2.8L IS USM
- EF 400mm f/2.8L IS USM
An interesting video shot with the unusual Laowa 24mm macro relay lens – it seems it comes with a waterproof cover that incorporates LED lighting (all Laowa new CP+ products)
3rd It’s suggested that Sigma will announce a 70-200 f/2.8 DG OS Sport lens this year [CR]
More CP+ interviews – one from Sony concentrating on lens design [IR]
2nd The Irix 11mm f4 lens has been announced [Irix 11mm f4]. It will be on show (and on sale) at ‘The Photography Show’ in the UK 18th-21st March.
I’ll be at the show all four days, since I’m at the Innova stand giving a series of talks about making large prints.
28th Hasselblad announce a 120mm lens for the X1D and mention three others for later this year – info on our medium format page
There is a set of 50MP sample (pre-production lens) Sigma 14/1.8 images available at DPR
Mention of a new 135mm Zeiss Batis for next week [PR]
27th It’s interview time for the CP+ show and there is an interesting Sigma one at DPR
Having just spent some time with my Sigma 12-24mm review I’d agree with this…
– You’ve told me previously that you really want Sigma to make more wideangle lenses. Do you think you’re achieving that goal with the 12-24mm and new 14mm?
Yes, but I’m still not satisfied. I think we need to make more wide-angle lenses. A fast 14mm was one of the lenses that our customers were asking for. Most existing 14mm lenses are F2.8, so F1.8 was a challenge.
The new Sigma 14mm F1.8 is the fastest lens of its kind, and according to Sigma, should outperform competitive, slower designs from other manufacturers.
– What have you learned, from making the Art series?
We’ve learned that some customers require exceptional lens performance. We believe that our mission is to make products that other manufacturers don’t have. If we just released similarly-specified lenses to existing models, we wouldn’t be contributing to the industry, or benefiting customers. So our Art series is meant to provide the best performance.
They’re bulky and heavy, it’s true, but our customers like them because of the performance. That’s what we learned.
I eagerly await Sigma’s first wide tilt/shift lens ;-)
26th The CP+ show is running in Japan, and amongst the products on display are a range of new lenses from Laowa (Venus lens). A 25mm 2.5-5x macro, 15/2.8 Sony FE, 24mm relay lens, tilt and shift converters and a 7.5mm f2 MFT lens.
They make some interesting stuff that I’ve really enjoyed testing, to the extent that Karen uses their dual head macro flash for many of her jewellery photos.
For those of you super keen to sign up to hear about the new Sigma lenses, B&H have a pre-pre order notification service – yes it’s for real
25th A new m4/3 lens catalogue (multiple manufacturers) [PDF] shows just how far the range has come – well worth a browse if you like lenses…
21st Sigma announce 4 new lenses as expected – full details are in a news post (part of my changes to how the site is organised – hopefully making things easier to find)
18th A suggestion that we’re about to see several lenses from Sigma [Nok]
- 135mm F1.8 DG HSM | Art
- 14mm F1.8 DG HSM | Art
- 24-70 mm F 2.8 DG OS HSM | Art
- 100-400 mm F5 – 6.3 DG OS HSM | Contemporary
Mount: Canon · Nikon · Sigma
17th Irix have info about their 11mm f/4 lens [Irix] – definitely one to try…
15th As expected, Canon announce a new (smaller – see right) version of their EF-S18-55mm kit lens
The new Canon EF-S 18-55mm f/4-5.6 IS STM lens is nearly 20 percent smaller than the EF-S 18-55mm f/3.5-5.6 IS STM lens, without sacrificing image quality. Features of the lens include:
Compact-size, Standard Zoom Lens with High Image Quality
Lead Screw-type STM
Image Stabilization at up to 45 Stops of Shake Correction
The Canon EF-S 18-55mm f/4-5.6 IS STM lens is scheduled to be available in early April 2017 for an estimated retail price of $249.99**.

7th I’ve been having a look at using the Samyang (Rokinon) 12mm f/2.8 fisheye lens and have written up a review of using it on my 5Ds.
Mainly about using the lens (so no MTF charts) including how its stereographic projection geometry differs from most other fisheye lenses.
Two new Tamron lenses announced…
SP 70-200mm F/2.8 Di VC USD G2 (Model A025)
February 6, 2017, Commack, NY – Tamron, a leading manufacturer of optics for diverse applications, announces the launch of SP 70-200mm F/2.8 Di VC USD G2 (Model A025), a new telephoto zoom lens product for full-frame and APS-C DSLR cameras. Model A025 was developed by substantially enhancing the features of its predecessor. These include a thorough review of the optical, mechanical and electronic designs to increase autofocus speed and precision, reinforce VC (Vibration Compensation) functions and to shorten the MOD. New features include eBAND Coating, Moisture-Proof and Dust-Resistant Construction, Fluorine Coating and compatibility with teleconverters. The lens design features a metal-based barrel for improved handling and ease-of-use. The result of this dramatic evolution is Model A025, a high-speed telephoto lens that widens the scope of expression for photography in a broad range of genres, such as portraits, landscapes, sports and photojournalism. The lens is expected to be available in the U.S. in March at $1299.
10-24mm F/3.5-4.5 Di II VC HLD (Model B023)
February 6, 2017, Commack, NY – Tamron, a leading manufacturer of optics for diverse applications, announces the launch of 10-24mm F/3.5-4.5 Di II VC HLD (Model B023), a new ultra-wideangle zoom lens for APS-C DSLR cameras. The lens is expected to be available in the U.S. this Spring at $499.
Model B023 is a wideangle zoom lens that covers an exceptionally large range—the largest focal length range in its class1 (35mm equivalent is 16mm to 37mm). The lens is ideal for street photography, landscapes, group photos and casual everyday scenes. In 2008, Tamron launched the SP AF 10-24mm F/3.5-4.5 Di II LD Aspherical [IF] (Model B001) that provided an unprecedented focal length range in its class. Building on that lens’s popularity, the successor Model B023 has improved optical performance and new features. It embodies Tamron’s most advanced technologies, including the VC (Vibration Compensation) system, Moisture-Resistant Construction and Fluorine Coating, and the first implementation of Tamron’s new HLD (High/Low torque modulated Drive). Additionally, the Model B023 has a refreshing new design derived from the design of the new product lineup in the SP series.

3rd The Sigma 85/1.4 Art lens gets impressive test scores [DxO]
With the new site, I’m going to be looking at more lenses, and the Sigma 12-24mm F4 DG HSM Art is one I’m looking forward to trying, especially since I have the Canon 11-24 f4L
I’m going to be concentrating on actually using more unusual lenses, since there are technical lens review sites aplenty for the ‘standard’ stuff or for people who pore over tables and graphs ;-)
2nd There is a new 70-300 on the way from Tamron – SP 70-300 mm f/4-5.6 Di VC USD [nok]
31st Canon has been working on diffractive elements for lenses for several years, and a recent US patent [USP] shows some aspects of creating them with two clear resins of different optical properties.
A mould has the diffractive pattern, and creates the first part of the diffractive element in conjunction with one surface of a normal glass lens.
A second lens element and a different resin produces the second part.
Lots more detail in the patent, but as with patents, don’t expect an easy read ;-)
The good old EF 50/1.4 gets another mention [CR] for a ‘late this year’ update (hey, it’s only a 1993 lens, so no rush…)
27th Reports of a new EF 70-200mm f/4L IS II on the way at some point in the future… [CR]
It will … “incorporate new processes and technologies.” [see below ;-) ]
24th An interesting selection of points sent to us (thanks) from a source in the Far East, said to be from part of a Canon PP presentation
- EF lens mount 3oth anniversary – over 120 million lenses
- Not all done – new challenges!
- Smarter lenses work with still and video cameras
- Premium lenses to support 100+MP sensors and beyond
- Current premium lenses still have too much hand assembly and testing
- Canon developed optical and mechanical design software
- Developments in new glass manufacturing to reduce lead time and supply constraints
Not sure it actually says much new, but I’ve asked for some pictures…
21st In the GFX release info there were some interesting accessories listed. What caught my attention was the adapter for view cameras.
View Camera Adapter G – allows the GFX 50S to be used as a digital back. The view camera adapter allows the GFX 50S to be mounted to the standard universal-type back of a view camera. This allows the use of FUJINON large format camera lenses, such as the CM-W FUJINON lens series. The camera or lens shutter can be triggered, allowing the user to choose the optimum method. The large image circle and the bellows of the view camera can be used with tilt, shift and swing movements, effective for product and architectural photography.
*There may be instances in which the adapter cannot be mounted depending on the shape of the view camera.
Here’s my version – a $15 Canon view camera adapter
What Canon Lenses to expect this year? At the moment, I’ve not seen (nor been sent) anything that fall into the ‘imminent’ (and therefore much more believable) category.
- A ‘Different’ type of 135mm [CR] This could of course be related to Canon’s 135mm lens patent from December [now on the 2016 lens info archive page]
- A small (EF-S?) prime [CR]
- Yet another version of the EF-S18-55mm is always a possibility with the 750D/760D replacements.
9th A new EF 135/2 L IS is suggested for later this year [CR] – after any EF 85/1.4 L IS
A detailed Canon patent [USPTO] describes a tilt/shift lens adapter, such as for EF to EF-M mount, where the difference in flange distance allows for the mechanism to add tilt and shift ability.
It’s interesting to note that this is a ‘smart’ tilt/shift mechanism which reports the settings back to the camera.
As such it could find use in a normal TS-E lens, allowing (finally) for tilt and shift info to be stored in EXIF data.
The block diagram suggests that the movements could be under camera control
Knowing the image circle size of the lens and the sensor size allows the camera to work out just how much shift is available (and display this on the camera in various ways).
Here’s the adapter showing lens tilt
…and here it is showing lens shift.
An interesting patent, not only for use with an adapter (and any size sensor), but also allowing for a considerable jump in TS-E lens complexity (AF for example).
BTW If you are not familiar with T/S lenses, I’ve written quite a few articles – just look for ’tilt/shift’ in the article categories list at the right.
7th A suggestion that Sigma will shortly bring out a 24-70mm f/2.8 OS Art lens [CR]
