New lenses – facts, rumours and speculation
22nd The Laowa 9mm f/2.8 Zero-D wide angle is announced for mirrorless (EF-M,Sony E, Fuji).
21st The new Canon 70-200 F4L IS II is due in April [CR]
20th You may have noticed the optical design diagrams I often include from patents. Well it appears that a lot of patents have more than enough detail to set up an optical bench model. Bill Claff of the Photons to Photos site has set up an interactive optical bench which includes quite a few designs, including recently a couple of canon examples, such as this for the EF-S 18-200mm f/3.5-5.6 IS
19th An interesting interview [DPR] with the Sigma CEO shows some real desire to produce even more great lenses.
I was interested in his suggestion that given the choice, his aim was for optical quality over lightness – one of the more open and informative camera industry CEOs
15th A Canon US patent application looks at aspects of making the moulded elements for diffractive optics (DO) elements.
Looks as if we’ll see a EF 70-200mm f/4L IS II and EF-M 32mm f/1.4 STM appear sometime this year [Nok]
The 70-200/4 is quite a good lens so it will be interesting to see how a new design improves it – the 32mm give a ~51mm equivalent FOV, making for a nice ‘standard lens’
I’ve been out trying out the TS-E50. Full tilt at f/2.8 – De Montfort university campus near my home. [click to enlarge]
Although not a fan of ‘small world’ or ’tilt-shift effect’ images, I definitely had to try it with the TS-E50.
13th Canon have sent me the TS-E5omm F2.8L Macro lens to have a go with – I’m hoping to add a TS-E50mm review to go with my TS-E135 review in a few weeks.
12th A suggestion that development of Canon’s 24-70 2.8L IS is ongoing [CR] but not a lens for this year.
After the big trade shows a series of ‘interviews’ tend to emerge, helping fill the slack for photo news sites. These range from the bland/anodyne to genuinely interesting.
- Sigma will develop new full-frame mirrorless lenses for Sony E-mount (only the wide angle lenses can be made smaller)
- Sigma will make more DSLR lenses available in Sony E-mount in the future
- Sigma will develop new zoom lenses for Nikon.Canon DSLR cameras
- The new Sigma 70mm f/2.8 DG Macro Art lens is not available in Nikon F-mount because of the new autofocus motor they implemented in the lens (similar to the Nikon AF-P lenses)
- The new Sigma 105mm f/1.4 DG HSM Art lens is much bigger than the Nikon version because it offers less vignetting (2 EV for the Nikon lens at f/1.4 vs. 1.6 EV for the Sigma lens)
Last week (main rumour page) Sigma’s CEO was interviewed for a French website Mizuwari [Google xlt] where he covers quite a few topics such as the use of plastic for lens elements (poor thermal performance), curved sensors (good for phones), Foveon chips for others (it depends) and possible MF from Sigma (too expensive).
9th A Japanese patent application [HiL] includes and APS-C 18-135 f/3.6-6.5 zoom and an 18-185 version for mirrorless/compact
The elements 21/22 in the example above have a graded optical transmission (darker at the edges), which improves some aspects of image sharpness and OOF performance.
7th I’ve just published my first review of Canon’s new TS-E lenses, starting with the TS-E135 f4L Macro
The review includes a lot of detail about how you use this excellent lens, not just lens info.
One example – taking a photo looking down my stairs at f/4 with all steps in focus.
New firmware for three EF-M lenses supports ‘dual sensing IS’ – as found on the new M50 (and only M50)
6th Just how big a rear element can you fit into the EF mount? The Mitakon Speedmaster 50mm f/0.95 seen at CP+ has a go [DCW]
That pretty much rules it out for Nikon F and Sony FE.
2nd One for macro fans – I’ve just finished my review of the Laowa 25mm f2.8 2.5-5x macro lens
Here next to my Canon MP-E65, which it slightly bests, wide open
1st A Japanese patent application for a 15-105 mm F1.8 – 6.0 for APS – C mirrorless lens appears [HL]
Zoom ratio: 6.75
Focal length: 15.21 52.83 102.65 mm
F no .: 1.85 4.20 6.00
Image angle: 36.19 14.50 7.58
Image height: 11.13 13.66 13.66 mm
Lens length: 83.84 101.55 121.52 mm
Back focus: 3.81 3.81 3.81 mm
A Canon patent application [USPTO] looks at eliminating the annoying self zoom creep of some lenses when pointed up/down.
27th Updates on the way for Sigma lens firmware, offering Canon lens aberration data.
Sigma has announced the two new lenses – both look very interesting examples of lens design
I’ve just published a news article with all the new Sigma lens info
Also of note is the addition of E mount versions for many ‘Art’ lenses
Here’s the internal design of the 105/1.4
25th Two hefty lenses in the ‘Art’ category on the way from Sigma. [DCI]
A 105mmf/1.4 (described as possibly for Sony FE as well as Canon/Nikon)
A 70mm f/2.6 macro
23rd The Speedlite 470 EX – AI
- Auto intelligent (AI) bounce mode of “Full Auto” and “Semi Auto”.
- With an electric head rotation device, the 470EX-AI automatically determines the optimal bounce position eliminating unnecessary shadows.
- The guide number is 47 (105 mm).
- It is driven by 4 AA batteries.
- It covers the field angle of 24 – 105 mm. Wide panel (14 mm adapter) allows light to spread wide.
- Clip-on bounce adapter that makes light more soft.
- Equipped with a dot matrix display that can display more detailed information.
- The setting can be quickly changed with the shortcut button and the controller wheel.
- Size 74.6 x 130.4 x 105.1 mm.
- Weight 385 g (excluding batteries).
A note from Sigma in the US says their new 12-24mm f/2.8 will be available for $1299 in mid March.
22nd The Tamron 70-210mm f4 VC is announced.
Tokina will soon be announcing an ‘Opera’ 50/1.4 AF full frame lens
It won’t appear until September though [Nok]
The Canon 135 is here and it is one hefty lens…
20th The Samyang 50/1.2 is announced
I’ve a Canon TS-E135mm F4L Macro coming for a review
please email me if you’ve any specific questions?
18th A busy time at [Nokishita] with images of a Samyang XP 50/1.2
and a suggestion that the pending Tamron lens is a 70 – 210 mm F/4 Di VC USD
15th A new teleconverter patent application from Canon [USPTO] includes several optical formulae (the TC is marked ‘LC’ below)
Three Canon zoom lens US patent applications – more video oriented with high zoom ratios.
A Canon US patent application [USPTO] looks at using diffractive optics for longer wavelength infra red optics
It’s still time for superzooms for 1″ sensors in a series of Japanese patents for 20x zooms. [HL]
14th Tamron have a new lens teaser image doing the rounds – difficult to say anything more than it doesn’t look like an ultra-wide or a long telephoto. No doubt it will appear soon for CP+
13th An EF-M 32/1.4 is expected [CR] in the run up to Photokina.
9th The Sigma 14-24 is announced [info and specs]. It will be interesting to compare with the 12-24mm that’s in my detailed Sigma 12-24mm f4 review and exploration of using the 12-24mm for architecture.
A Canon patent application for mirrorless zoom designs in the ~18-150 f3.5-6.5 category [USPTO]
8th Images of the new Sigma lens appear [Nok] 1150 gm – 11 groups 17 elements – 9 blade circular aperture
7th Suggestions that we are soon getting a Sigma 14-24 mm f / 2.8 DG HSM Art [Nok]
2nd A new 24-70 2.8L is suggested in the Photokina timeframe [CR] but with something ‘different’
How about a change to Canon’s long lasting detachable lens mount? A lot of people would like to see Canon make it easier to fit to ‘Arca Swiss’ style base plates.
1st An upcoming EF-M lens is said to be ’50mm equiv’ and ‘fast’ [CR]
Some specs for the Laowa 2.5-5x Macro I’m testing
I’m only just getting into some testing, but here’s an animation, based on stacking 114 images (x 50MP) at x5 and f/2.8
A 100% crop of the actual still image with a scale marker [click to enlarge]
30th Maybe I’ll get round to updating my 70-200 2.8L IS some time … it seems there is talk of a Mk3 version out for testing [CR]
28th Some shots of a Laowa 9mm f/2.8 lens for mirrorless (inc. EF-M) are spotted [PR]
If the image quality is on a par with the Laowa 12mm f/2.8 I reviewed then this is a great APS-C option.
23rd Venus Lens have kindly sent me the Laowa 25mm f/2.8 2.5-5x Extreme Macro lens to try out. I’ll be writing up a review in due course. I’m very interested in this lens since I happen to have the (somewhat bigger) Canon MP-E65 and use it for quite a bit of our macro work. – please do email me if you’ve any specific questions?

18th Suggestions for two EF-M lenses this year [CR] – first up a prime of some sort within the next month or so.
16th I’ve been testing a new lens adapter for the TS-E17 and TS-E24 tilt/shift lenses.
The Rogeti TSE Frame lets you attach the lens to the tripod and shift the camera. I get to see a lot of camera gadgets, and not many get such a quick promotion to my camera bag ;-)
11th Two interesting primes in a Japanese patent application a 15/4 EF and a 9.5/4 for APS-C (likely mirrorless, with short backfocus distance) [via CN]
Some short telephoto primes in a new Japanese patent application [via CN]
- EF 50mm f/1.8
- F 85mm f/1.4
- EF 85mm f/1.8
- EF 100mm f/1.8
A Canon US patent application [USPTO] shows a lens barrel design for inserting optical filters into and out of the optical path
A patent app last year showed a mirror lens with a variable electronic ND filter in it. A new US application [USPTO] shows an electrochromic variable filter design. A compound changes its optical properties in response to an applied electrical signal via transparent electrodes.
One of the issues is avoiding colour shift as the density is changed, whilst the chemical mix of the inner filtering layer sets the overall transmission spectral response.
This example shows the filter inside a lens.
You may remember that the 200-400 was first mentioned in Feb 2011, but not formally announced until May 2013. I’m minded to suggest that the days of being able to ‘get away with’ such a long time gap are long gone…
8th The Samyang 14/2.8 AF lens is announced for the EF mount.
4th It looks as if we’re about to start seeing more EF mount AF lenses from third party lens makers
A Samyang 14/2.8 was announced for E mount – now it looks as if we might be seeing it in EF?
If it’s of similar quality to the Samyang XP 14/2.4 I reviewed a while ago, this looks interesting.
A good indication of how much easier curved sensors make some aspects of lens design is shown in this Nikon full frame patent app ~50mm f/2.8 [via HL]
1st A Japanese patent application spotted at CN shows aspects of adding IS to a TS-E tilt shift lens (including the problems of flexible electronic connectors)
A US patent from last January [Jan 7th 2017 here] includes a similar diagram, although in the context of a lens adapter with tilt and shift.
A US patent application [from July] found in Oct 16th here shows an actual construction for a TS-E lens with IS/AF.
With the 2017 patent info, I had wondered if updated TS-E lenses might get some more electronics. Unfortunately, the new TS-E50/90/135 lenses don’t even have encoders to let the body know what the tilt/shift settings are, so we’ve a long way to go. The TS-E24 is very good optically and the 17mm is one of my go-to lenses. I don’t see any pressing requirements for updating either, especially since wide TS-E lenses tend to be used in circumstances where AF and IS are of limited use. OK I’d not be averse to to a TS-E14 0r 15, but I suspect that’s such a difficult lens to design with a large image circle, that it’s well down Canon’s to-do list.
