For several years I've been collecting information and links for Canon's new EF lenses and rumours about even newer ones. This page shows the latest information I've been sent or found on the web. I've also written numerous articles and reviews covering lenses and photography related issues.
BTW If you're a lens maker who supplies lenses in EF mount and wants me to look at a potential lens review, then just give us a call? It includes other makes of lenses that catch my attention too. Detailed information about some current lenses can be found on specific pages via the main rumours index.
Over the years I've received all kinds of lens rumour info - some more believable/risible than others. Please do use your own judgement when reading the stuff here, and remember that what I've collected here is for entertainment as much as anything else. Oh, and that 42mm f1.0 lens that you can see at the right is a fake...
Two tables of information that may be of interest are included here. The date codes article is on our EFLens.com site.
Well, it seems that Canon have been a -bit- more forthcoming about lens developments [CNET]
So, yes, there will be one, and it might even be diffractive optics, oh, and there will be more EF-M lenses too.
The sort of info that if it hadn't come from Canon, I might not have even bothered to mention ;-)
15th Updates may be delayed this week, since I'm on holiday ;-)
Thanks to everyone who has ever purchased something via our links. If you follow a link below and then buy absolutely anything (not even camera related) it helps me run this site (the articles are all written by myself in my spare time)
BTW If you've just found the site via the rumours pages - please do have a look round the articles and reviews, since they are far more important to me, in helping people get more out of their photography.
Three lenses announced - includes the new 400mm F4 Diffractive optics mkII
The Canon EF 400mm f/4 DO IS II USM lens delivers brilliant high-speed performance for professionals with minimal glare and superb image quality. Taking advantage of the best in lens technology, it features gapless dual-layer diffractive optical elements for improved diffraction efficiency with reduced flare. These elements are arranged with a large-diameter ground aspheric lens and a UD lens for a new level of sharpness and clarity. New coatings help to reduce ghosting, ensure excellent color balance and reduce fingerprints on the front and rear of the lens.
Professional L-series dust- and water-resistant construction is complemented by impressive performance: a 3 mode Image Stabilization system offers up to four stops of compensation and can even prevent operational errors when the camera is mounted on a tripod. AF stop buttons placed on the front of the lens can automatically stop focusing at any time; full time manual focus ensures complete control no matter the AF mode, and a Power Focus (PF) mode makes for smooth focus transitions when shooting movies. The EF 400mm f/4 DO IS II USM focuses down to 10.8 ft. (3.3 meters), has a 9-blade aperture for pleasing, soft, out-of-focus areas, and is constructed with environmentally friendly lead-free

5th In a product that will excite far more people than possibly have a genuine use for it, Zeiss will be bringing out an 85mm/1.4 Otus at Photokina.
And, for those with vastly more money than sense ...a super sharp expensive lens won't improve your photos any more than the last expensive bit of glass you added to your collection. There is however, a nice range of Hasselbling products made just for you ;-)
I'd have thought the 180 (a very good lens) would get hybrid IS - perhaps this patent is more of a 'because we haven't given up on DO' statement.
The 'year of the lens' runs into timing issues wrt to Canon 'L' primes [CR] - seems it was meant to be 2015
Perhaps still time for an ultra-wide zoom and replacement for the 100-400 which we've been told is coming (again) with the 7D2 - I'm minded to say though, that without pictures, 100-400 rumours don't count ;-)
26th On/off reports that Rokinon (Samyang) will bring out a 50/1.2 lens [PR]
I've got an Olympus 50/1.2 and can confirm that manual focusing at f/1.2 is tricky with any standard DSLR focus screen ;-)
23rd An interview with Canon about their two latest wide zooms [DC - Google xlt]
Unusually for a machine translation, not too difficult to follow.
The optical improvements of the new 16-35 are fairly clear in a comparison of MTF charts, as is the observation in the article that the old 16-35 is just fine for APS-H ;-)
Discussions cover many of the aspects of lens design that are only now becoming possible with cheaper aspheric optical elements.
Not that long ago, a lens such as the rather good EF-S10-18 [see my 10-18 review for more] could not have been made at a budget price.
There is even the comment that:
"... By super-wide-angle zoom image quality is good came out to the periphery, and we look forward to the advent of high-resolution model of the EOS."
18th Are Sigma looking at the Cine lens market? [SigR]
12th A potential set of specs appear for an updated 100-400 [CR]
EF 100-400 f/4.5-5.6L IS II Specs
Rotating zoom ring
New IS system
82mm filter thread
10th Whilst looking for a lens hood for the EF-S 10-18mm I recently reviewed, I found that a cheap £2.50 EW73-B hood from eBay could be simply modified to match the £25-30 Canon EW73-C
Given my ability to lose lens caps and hoods, quite a saving ;-)
9th Some suggestions that the next from Sigma will be 24 and 85mm 1.4 art lenses - quite a collection of other lenses listed with estimates of them turning up this year [SR]
18th A new Tamron lens for EOS M, the 18-200mm Di III VC (Model B011), should appear tomorrow. [DCI - Google xlt]
This would be the first third party EF-M lens with a native EF-M mount.
17th The EF-M lens appears
United Kingdom, Republic of Ireland, 17 June 2014 – Canon today announces a new addition to its EF-M lens range with the introduction of its first dedicated telephoto zoom lens – the EF-M 55-200mm f/4.5-6.3 IS STM. Designed for Canon’s Compact System Camera, the EOS M, the new EF-M 55-200mm f/4.5-6.3 IS STM features Canon's signature optical performance, advanced Stepping Motor Technology (STM), a 3.5-stop optical Image Stabilizer, and provides a versatile 55-200mm focal range to help users get closer to the subjects they love.
Taking you closer
The EF-M 55-200mm f/4.5-6.3 IS STM joins three existing lenses in the EF-M range, which together offer a diverse variety of focal lengths from 11-200mm. The perfect addition to any EOS M kit bag, the new lens opens additional creative possibilities for EOS M shooters through its suitability to capture a wide selection of scenes – from eye-catching portraits at 55mm, to wildlife at 200mm.
Leading optical technologies for incredible images
Developed using the company’s unparalleled optical expertise, the EF-M 55-200mm f/4.5-6.3 IS STM features Canon’s powerful optical Image Stabilizer and STM technology to deliver outstanding levels of detail when shooting stills and movies. When shooting movies specifically, STM technology ensures smooth focus transitions, as focus shifts from one subject to another. The STM mechanism also provides near-silent focusing, giving videographers the ability to shoot movie soundtracks which capture the natural ambience of the scene in front of them. Additionally, thanks to a highly-effective 3.5-stop optical Image Stabilizer, which reduces visible camera shake, users can also shoot sharp stills while using the zoom, and steady movies while capturing action.
Designed to make great photography easy
Constructed of a high quality metal exterior – a trademark of the EF-M lens range – the EF-M 55-200mm f/4.5-6.3 IS STM is also compact, lightweight and portable, making it ideal for everyday use. Inside the lens, an Ultra-low Dispersion (UD) element delivers outstanding image quality throughout the zoom range. Furthermore, its non-rotating front element makes it easy to maintain a consistent effect when using filters, and the full-time manual focus ring offers greater creative freedom to adjust focus during shooting.
EF-M 55-200mm f/4.5-6.3 IS STM key features:
· Get closer to the action with your EOS-M camera
· Image Stabilizer keeps images sharp
· Compact enough to go anywhere
· Smooth, near-silent STM focusing
· Make quick adjustments with a manual focus ring
· Shoot great quality images – full of sharp details and rich colour
Pricing and availability
The EF-M 55-200mm f/4.5-6.3 IS STM is available from July with an SRP £329.99/€389.99.

"Adopt one glass molded aspherical lens and one UD lens
The 22% shortening the overall length compared to the EF-S 55-250mm IS STM

11thCanon have published more information about the EF-S10-18 and EF 16-35 f/4 L IS
I've updated my EF-S 10-18 review with more technical info
27th Sigma to announce an 85/1.4 Art lens at Photokina? [CR]
Also mentioned, something long for next year...
24th A new patent from Canon for a 100-400 - this time it's the return of diffractive optics [EG-xlt]
Patent shows 100-400 mm F4.5-5.6 and 70-300 mm F4.5-5.6
22nd A whole series of wide zooms appear in some new Sigma patents [EG-xlt]
15-30 mm F1.8, 17-35mm F1.8, 16-50 mM F2.8, 12-24mm F2.8
All are APS-C
20th Maybe a typo, but a Canon 50/1.2L II gets mentioned in a CPN video article.
It also seems that several rumour sites have been sent the same info that the 100-400 is soon due for replacement. Not sure where it originated, but thanks for sending in the info (including that it would be a fair bit more expensive).
16th The two new wide lenses are mentioned in a CPN article.
15th A Canon f/2.8 ultrawide zoom is due for announcement later this year [CR] 14-24mm is suggested, although in the past we've had 12-24 suggested (2mm extra bragging rights for marketing ;-)
7th An imminent anouncement is suggested [DCI Goog xlt] for two lenses.
The two wide zooms are an EF-S 10-18mm f/4.5-5.6 IS STM and the EF 16-35mm f/4L IS USM.
We're also told that "all the new TS-E lenses" will be on show at Photokina.
The 10-18 will be popular with some of the real-estate agents I teach property photography to. Very few of them like taking tripods with them ;-)
It's the TS-E ones that interest me the most, but these have been in rumours since the TS-E17 was announced [Feb 2009] so I've long stopped holding my breath...
6th A few lens snippets [CR], with an expensive 11-24 and an IS f/4 version of the 16-35. There is even a suggested $3k price ticket for the all new 100-400.
It's been a thin time for Canon rumours of late. I'm assuming Canon are going to do something this year... ;-)
5th Suggestion of a replacement (or even all new) EF-S ultrawide [CR] - something for the 7D2?
Interesting article [IR] about how Panasonic address some of the issues in making aspheric lens elements.
If you didn't know it, cheaper manufacturing of aspheric elements is one of the reasons that we have so many great lenses now (at a reasonable price) compared to 25 years ago.
30th Canon celebrates making its 100 millionth EF lens on the 22nd
TOKYO, Japan, April 30, 2014—Canon Inc. today celebrated an impressive lens-manufacturing milestone with the production on April 22, 2014, of the Company’s 100-millionth EF-series interchangeable lens for EOS cameras—an EF200-400mm f/4L IS USM Extender 1.4x.
28th New Samyang lenses tomorrow:
35mm f/1.4 Canon AE
300mm f/6.3 Mirror DSLR photo lenses
Samyang 10mm T3.1
Note AE control for the Canon lens (no AF yet)
There are lots of Canon lenses in the latest US rebate scheme - full list on main rumour page,
23rd Lots of speculation around what Sigma will announce at Photokina, with a 24/1.4 looking good and a 135/1.8 doing well in the wish lists...
22nd A new product is teased at Canon's HK FB page (see main rumour page for pic)
Speculation would like a new fast prime - there are a few could do with an update (35/1.4, 50/1.4) but it could be another extremely expensive cine lens, or just a camcorder...
Samyang's 3 lenses are hinted at: 35mm f/1.4 AE lens, a 7.5mm T3.8 cinema fisheye lens for MFT and 12mm cinema lens for APS-C based mirrorless cameras [PR]
21st Suggestions [CR] that we will finally see an update to the TS-E45 and a replacement for the TS-E90 - both getting 'L' status.
This has been a regular for a few years, and some time ago we were told that new TS-E lenses would finally have encoders to allow for recording movement info in EXIF data. This could only be done with a whole new movements mechanism.
I've seen numerous comments elsewhere that the T/S lenses are fragile - IMHO that's due more to ham-fisted use inexperience than any great design issues.
Or perhaps I just treat £2000 lenses with a bit more care than a rental car ;-)
There is a Sigma 35/1.4 patent (inc. a version with IS) [EG-xlt]
It seem that someone running Samyang's FB page got a little ahead of themselves [DH-xlt] and that Samyang is not about to move to AF lenses. It seems that there is an awful lot of proprietary info needed to do it properly for most formats. Electronic aperture control amy feature, since it's somewhat easier to implement.
Given that Sigma and the like have spent years working on AF compatibility and still have problems every so often, I can see why Samyang might want to leave well alone for the time being
19th There are mumerous praises of the Sigma 50/1.4 after DxOmark agrees that it touches Zeiss Otus performance at a quarter of the price.
The next Otus is likely to be an 85/1.4 at Photokina, and with Sigma's lens designers on a roll, a matching version at a fraction of te price (and with AF) could be along this time next year (or sooner was hinted to us).
Added to this mix [CR] is the suggestion of a couple of Zeiss T/S lenses and a zoom - yes, they'll be cheap, I don't think ;-)
Meanwhile, another patent for a Canon 24-70 IS appears [EG-xlt] with 18 elements in 13 groups, this is a complex lens.
Samyang has posted a few more teasers about upcoming lenses later this month, but given their habit of pre-announcements and multiple releases, it's anyone's guess what might be coming - AF is regularly mentioned (50 and 85 suggested).
12th A Canon 22-46 zoom patent [EG-xlt] Specs look like a small size zoom for EF-M.
11th A pre-order price of just $949 for the Sigma 50/1.4 B&H | Adorama - available for Sigma, Sony, Nikon, and Canon mounts in late April.
If the early tests are anything to go by, this lens will be in short supply for a while, but more importantly, it throws down a few challenges to Canon/Nikon in the performance department.
Want to blow $300 on a creative (their word not mine ;-) lens? The Lensbaby 5.8mm circular fisheye is here. Whilst my own (15mm and 8-15) are some of the most flare resistant lenses I have, the Lensbaby has features such as:
'Polished internal barrel for creative flare & reflection' and a still more useless 'hyperfocal scale to aid in focusing'
Why do I tend to dislike such lenses? There is always a bit of a 'new toy' effect with any new kit. The man with a new hammer sees every problem as a nail... Suddenly every effect seems new and creative. I try and get past this before I risk using such kit on a paying job ;-) Most people get past it and explore what they can do with whatever new capabilities that come with the new kit, but with a more critical eye.
You've only got to see how much Lensbaby kit is available used, to see that their products are definitely aimed at the 'new hammer' period ;-)
If you want to experiment with cheaper fisheye lenses, get a good one, such as one of the Samyang models. That 'creative flare and internal reflection' features of the Lensbaby might, I suspect, quickly become an annoyance. [my own 8-15mm use]
9th Hints of a (very reasonable) price for the Sigma 50/1.4 at just over $1k [PR]
Some views of Canon's $33k 17-120 T2.9 cine lens [PB]
The Mitakon 50mm f/0.95 Sony E mount (FF) lens will go for $800 [SAR]
The Sigma review below is updated to compare with the Zeiss Otus and the comparisons are good
"The Sigma 50mm ƒ/1.4 Art is the most exciting lens we're likely to review this year. All competing lenses from Canon and Nikon fell short when compared to the resolving power of the 50mm Art. Compared to the mighty Zeiss 55mm ƒ/1.4 Otus, the Sigma holds its own, displaying nearly identical results"
6th A test of the Sigma 50/1.4 [SLG] suggests that it trounces anything other than the Zeiss Otus 55mm
31st Several Canon lens patents 50/85/100 appear [EG-xlt] - updates to some older primes?
In the very expensive category is a likely zoom cine lens from Canon for NAB [CR]
20th Several lenses from Samyang - mostly aimed at mirorless though.
There is an EF 10mm f/2.8 for APS-C - however this is the 10mm that was announced in December [full specs below] There is also an APS-C 12mm [SY]
18th Samyang are likely to make a lens announcement later this week - time to see how they handle AF?
17th Whilst Sigma is doing well these days, a Japanese court fines them [~£9m] for infringing some of Nikon's VR patents [PB]
15th An update for the 800/5.6 on its way later this year? [CR] Lighter, better optics and improved IS ?
12th The Canon patent floodgates seem to have opened with macro designs (inc. Hybrid IS) for: 180mm f/3.5 Macro IS, 200mm f/3.5 Macro IS, 300mm f/3.5 Macro IS [EG-xlt]
10th More patents from Canon [EG-xlt] 16-35mm f/4, 17-40 mm f/4 , 17-40 mm f/2.8-4 , 16-35mm f/2.8
The current 17-40 4L dates from 2003 and the 16-35 2.8L II is from 2007
3rd Diffractive optics are not dead yet... Two 600/4 patents from Canon [EG-xlt] DO is second one, a bit shorter.
2nd A range of Canon mail-in lens rebates in the US for March (links are B&H listings) As ever, check the full details needed to get your cash (not that I'd ever expect the fulfilment firms for such offers to try and pull a fast one... ;-)
18th Are we about to get some more EF-S lenses, other than the usual kit zooms? A 24mm EF-S with a new C-USM focus mechanism later this year [CR] The update to USM is likely to appear in a 50mm lens first of all.
Meanwhile, today's Canon patent is a 17-55 f/3.5-5.6 [EG-xlt] - a bit wider than the standard 18-55
4th With a 100-400 replacement expected for many years, it looks as if it might be getting closer, with a F4.5-5.6 IS 70-400 mm patent showing up [EG-xlt] No direct sign of whether the push-pull design is gone, but the fact that groups L1 and L2 diverge and L2/L3 converge, suggests it's a rotate to zoom option.
Sigma are going to expand the types of MTF chart they release for lenses [CR]
Of course this makes you wonder just how many people actually understand such charts and know what's relevant? Then again they always look good in reviews ;-)
1st Two interesting articles from Canon all about tele extenders [pt.1pt.2]
There's also one about the Canon 8-15 fisheye I found interesting to look through, even having regularly used the lens since it first came out [EF8-15 review]
27th After a flurry of lens patents, Canon show a domed (i.e. not flat) aperture device for lenses [EG-xlt] If you've ever taken apart an aperture unit (the iris mechanism) you'll see flat blades. In compact lenses, this means an air gap between elements big enough for the plane of the blades. Domed bladed let you place the aperture between two curved elements in a whole new way, giving new flexibility in lens design
25th The lens patents are coming thick and fast - this time, one I'd definitely buy, at 11-24mm f/4 [EG-xlt]
To get this field of view (up/down or side to side) I can stitch two images made with the TS-E17mm lens, which although it's going to be higher resolution, is not always a practical solution.
22nd More Canon lens patents [EG-xlt] This time with IS for medium telephoto lenses.
OK for replacing the 85 f/1.8 and 100 f/2, but the 135 f/2 L ? (not to mention the 135 f/2.8 soft focus)
21st A range of Canon Patents for EF-M wide zooms [EG-xlt]
13th At last - Canon patents a lens microadjustment automation process [EG-xlt] Combining contrast detect AF and Phase AF should allow a relatively simple adjustment process.
It's hardly difficult as it is (IMHO) but lots of emails and visits to our AF microadjustment page suggest otherwise ;-)
Meanwhile... I've been testing our new 100D with a few different lenses
29th More lens patents from Canon [EG-xlt] 18-55mm F3.5-5.6 , 18-200 mm F3.5-6.3 , 16-120 mm F3.5-5.6
The designs look to have a short backfocus distance appropriate to the EF-M specifications.
27th The 400/5.6L (from 1993) is currently difficult to source in some areas and we've had suggestions that it is due for a 400/5.6 L IS makeover. It's currently listed in the UK around £1100 (inc 20% Vat).
There are plenty to choose from and Canon have hinted at the 'year of the lens' in a recent interview. There is an ongoing update program for the non-L primes, several 'L' lenses are quite old, and there is still the so-so TS-E45 and quite good optically, but could do better in design TS-E90. Oh, and there are the perrenially 'real soon now' lenses, the 35/1.4L II and 100-400...
13th How about a 40mm f/0.85 for your EOS-M? Coming early next year for $2000 [Handevision]
Sample images via link.
10th Expected ever since the Sept 2008 announcement of the EF24 1.4L II, the 35 1.4L II is suggested as 'for real' next year [CR]
9th More Canon hints about lenses in an interview [see mirrorless page] - '2014 for lenses'
8th Samyang have announced availability of their 10/2.8 lens (crop sensor)
Given the quality of the Samyang 14/2.8 I've been testing of late, I expect it to do well. RRP in January is a just over £400.
6th Not happy with the Canon 200-400 with built in 1.4x TC?
A Canon patent shows several more examples, such as a 300-600 and 600/4 [EG-xlt]
Mainly concerns how inbuilt TC allows for much more optimisation of the TC for the lens.
Does this mean inbuilt x1.4 TCs for new versions of long white lenses?
2nd A Tamron patent for a 10mm f/1.8 and f/2.8 fisheye (APS-C 180 degree diagonal) [EG-xlt]
