Unveiled: Two New Canon Wide-Angle Zoom Lenses


Canon has announced two impressive new wide-angle zoom lenses: an EF-S mount lens to satisfy APS-C camera users and a full-frame EF mount L-series lens.

The EF 16-35mm f/4L IS USM Lens has been introduced as an alternative to the current 16-35mm f/2.8L II USM lens and incorporates an Optical Image Stabilizer. While the f/2.8 lens offers a faster maximum aperture, the stabilization system in the new lens compensates up to 4 stops to reduce blur when shooting with slower shutter speeds. And as an L-series lens, it provides the best Canon has to offer in terms of dust and water resistance, as well as overall durability. 

Optically, its combination of three aspherical and two UD lens elements minimizes aberrations throughout the zoom range and contributes to the creation of beautiful high-contrast images. A flourine lens coating reduces ghosting and flares and its circular 9-blade aperture enables pleasing background blur. The EW-82 Lens Hood is included with the lens to block stray light from entering the lens.

An inner focusing system, combined with ultrasonic autofocus motor (USM), realizes fast, quiet, and accurate autofocus and, when necessary, full-time manual focus is available. The minimum focus distance throughout the zoom range is 11" and its filter thread diameter is 77mm. L-series lenses are designed to meet the utmost in physical and optical standards and are regarded as a high point in the Canon DSLR lens line. The EF mount of this 16-35mm f/4L is designed for full-frame cameras, such as the current Canon 1Ds and 6D cameras and those of the 5D series.

Switching over to the APS-C side of the fence, Canon has brought forth the EF-S 10-18mm f/4.5-5.6 IS STM lens to shoot with current crop-sensor DSLRs, such as the 7D, 60D, 70D cameras, and those in the Rebel line. The 10-18mm offers advantages over the current EF-S 10-22mm lens in that it is significantly more compact and lightweight and it provides image stabilization.

Like the above 16-35mm lens, the EF-S 10-18mm is considered an ultra-wide-angle zoom lens and its 35mm focal length equivalence is 16-28.8mm. It optimizes its 4-group optical design to maintain a compact form factor that sits well on the generally more compact APS-C camera bodies. The optical system comprises a “large-diameter” lens element, as well as one aspherical and one UD element to control aberrations and create high-resolution, high-contrast images. Enhanced lens coatings also improve color balance while minimizing ghosting and flare.

As mentioned, the 10-18mm lens features Optical Image Stabilization for up to four stops of compensation against the blur from camera shake and its rear focusing system with stepping motor (STM) and improved autofocus algorithm provide fast AF and support the Canon EOS Movie Servo AF function for smooth and quiet continuous AF when shooting video. Full time manual focus is always available, even when in AF mode, and its minimum focus distance is 8.6". An optional dedicated lens hood, the EW-73C Lens Hood, will help to deflect unwanted light, reducing flares as well as protecting the lens from damage due to accidental impact.

I realise that this question is being posted Way after the lens was realeased. I currently own a not so new! Canon cropped sensor 450D.

The compromises made in not going, at the time for exteremly expensive full frame body Canon bodies, has to an exttent been offset by only purchasing L glass e.g 24-70 2.8 - really my go to lens which remains on the body most of the time- a, 7-200 2.8 IS and several Sigma Art series lens.

I want to purchase a true either a new 80d at is has a huge pixel count, but am well catered for now except true wide angle which is a fact of life when using a cropped sensor body.

Question one, given age of 450 digtial body, will this lens function with the body.

If there are any issues will either get 80d body, or full frame sensor Canon body.

At the moment would prefer to stay wiht small sensor body and look at this lens.

Reason for purchase, I reside in Australia and our family has farm/ranch with spectacular distanant range backdrops that wish to photograph. To date, been taking photos of areas in question with superb quality Nikon manual focus lens on the great Nikon FA and F100 film bodies. 

Thanks for any assitance you can provide.

Both the Canon EF 16-35mm f/4 IS and EF-S 10-18mm f/4.5-5.6 IS STM discussed in this article would be fully compatible with your Canon 450D. Both could also be used on the Canon 80D. As for full frame Canon cameras, the EF 16-35mm lens would be compatible while the EF-S 10-18mm lens would not.

Hi. Would this lens be great on a 600d? Thanks 

Both lenses listed will be compatible on the Canon 600D.

You haven't specified which lens you were referring to Vanessa. The EF 16-35mm lens is made specifically for full frame cameras. However, it can be fitted to an APS-C (cropped) camera body such as the 600D, but it will have a different field of view. The Canon APS-C cameras have a 1.6 times crop factor so it will be the equivalent FOV to a 25.6-56mm lens on a FF camera, so not a super wide angle lens at all. On the other hand the 10-18mm EF-S lens is specifically made for APS-C cameras (in fact they can't be used with FF cameras) and the field of view would equal a 16-28.8mm EF lens on a FF camera. Hope this answers your question. 

I am planning to buy Canon EF 16-35mm f/4L IS USM Lens but I am currently having a Canon 60D body. Does the lens work well with the Canon 60D?


Yes it does, it is fully compatible.  The 60D is an APS-C format camera, and Canon APS-C models cameras are compatible with any autofocus lenses made for the APS-C format (called "EF-S" type lenses) as well as those made for full-frame cameras (called "EF" type lenses).

everybody, stop being noobs and learn photography, i mean completely

Does the 10-18 lens work with a Canon 5D DSLR?

No it does not.  It is an "EF-S" type lens which indicates it is only compatible with APS-C model DSLR cameras.

Please tell me that the EF-S 10-18 will fit my 10D

It will not fit your 10D unfortunately.  The 10D predates the design of EF-S lenses and as a result is not compatible with any EF-S lenses, even future ones.

When is the lens coming out? Here is the gist of the situation: I am going on vacation the 17th of June. If I order it, will it be here in time?


Currently Canon has not been more specific than to estimate them to be available sometime in June.  Unfortunately due to this we are not able to garauntee its arrival/fulfillment to you by any particular date.  I am sorry about that.

I had been wondering why I found the EF-S 1-22 marked down for a while now. It had to be something new coming out.

Now I am faced with an interesting but difficult decision - one that we all may be faced with more regularly in the future ...

It seems an IS is now cheaper than the extra f stop in glass. Is it also the better choice? Most reviews of the older lens have said that for "perfect" image quality you have to stop the lens down a bit anyway. Now the new lens comes "pre-stopped-down" and is quite a bit smaller, lighter and cheaper. Will its overall quality prove to be comparable to the older model?

I suppose we will all now wait for the review of the new lens to make up our minds.

(The STM vs. USM discussion doesn't touch me too much at this point - my 50D wouldn't care, but I am looking at a 70D and that could change my priorities a bit.)


I have pre-ordered the 10-18mm to compliment a Tamron 18-270 I carry when I hike. the smaller size and weight will allow me to have full wide angle shots when I wish to use them. I did not have that previously and chose not to carry the 10-22 EF-s due to weight and size.


subject: Canon EF 16-35mm f/4L IS USM, 

I notice that the max aperature has dropped from F 2.8 to F 4, so I have a concern. I like the IS feature on a 70-200mm when I am shooting an event and walking around. 

How many photographers intend to use a lens like this off tripod?  How many use the lens 'wide open'?   I am looking to fill in my zoom lens needs below the 35mm and initially thought this a good fit. Another photographer who has the current model is asking me these questions and making me think. Should I buy the F2.8 model without IS?

Is the Image stabilization a valuable trade-off for the slightly more restricted F 4 ? 



According to Canon, the IS in the 16-35mm f/4 IS can compensate for up to four stops.  So, as you are only losing one stop going from f/2.8 to f/4, this lens can be shot hand held in lower light than the 16-35mm f/2.8 version of the lens.  That makes this lens an excellent choice when shooting in low light areas, where you might not always be able to bring a tripod along with you.  Nikon has had an image stabilized 16-35mm f/4 on the market for several years now, and it has been an extremely popular wide angle zoom among Nikon shooters (and one of my personal favorites).  I cannot think of why the Canon 16-35mm f/4 IS won’t have the same type of popularity among Canon shooters.

What i have been waiting for, a reasonably priced super wide for my Rebel.

Quick question - is the camera mount on the EF-s 10-18 metal or plastic?  I have seen too many plastic mounts broken in what should have been a survivable accident.

Canon has not indicated anywhere that I have been able to find which material the mount is made from.  The only two stock images I’ve seen so far appear to be plastic, but I can’t confirm at this point.  Once that information becomes available we will post it here for you.


I have Canon 6D and i am interested in wide angle lens -so, should i take the 16-35 2.8, or wait for the F4 IS L?

If you feel you would benefit from the shallower depth of field that shooting at f2.8 affords you, then you should opt for the f2.8 version.  However this new f4 version is quite appealing in that it is lower in cost, has a smaller sized filter which uses less expensive filters, and adds IS Image Stabilization which is a great benefit.  To date it’s their widest zoom lens to offer the feature for a full-frame camera.

This is showing up right on time. I'm in the market for just this thing. I'd have liked to purchsed the 16-35mm 2.8 but can't really justify spending that much cash. So I was prepared to settle for the 17-40. Now, if I could get it bundled with the 5D Mrk III I'd be in photog heaven.

The new 16-35mm f4 'L' IS USM lens is a far better buy Robert, but seeing as your post is 1 yr old you have probably already bought the f2.8?

That new 10-18 IS STM is an INCREDIBLE deal - less than half the price of the 10-22!  I've owned the 10-22 for a few years now, and it's a great lens, no question, but nowhere near the value proposition the 10-18 is.  I think that will get a lot more people interested in wide-angle photography, and it fits in nicely with the kit lenses most of these newcomers would already own.

What I've personally been waiting for is a version of the 22mm from the EF-M line that works on EF-S cameras...that would keep me in the Canon camp full-time (pair it with an SL1 to have a killer compact setup) instead of shooting m4/3 when I want to travel light.

I'd rather see Canon fully flesh out lenses for the EOS-M system:


        30mm F1.4 IS

        70mm F2.0 IS

        17mm F2.8 IS

         11mm F3.5 IS

          90mm F2.0 IS quasi macro (to 1:3 or so) 

With all due respect to B&H who is providing this space, if you need a wide angle for the EOS-M, the Canon EF-M 11-22mm f/4-5.6 STM lens is available from a variety of Canadian vendors. I have found this to be an excellent lens and feel that it is just as sharp as the 22mm prime. 

Which lens of the 2 confirgurations of the 10 - 18 mm lens should be used on a 20D for a housed camera underwater?  Also, does Ikelite now sell a port that will work with the 10 - 18 mm and allow the use of the zoom function?

Thank you.

There is only one version of a 10-18mm lens so I am not certain what the other “configuration” you are referring to may be.  If you could clarify that I’ll be happy to comment on it.  As far as a port for the new 10-18mm lens from Ikelite goes, this lens is just announced and there is not yet a port offered but they very likely will.  Feel free to check back with us in the future regarding its availability. 

You have two lens identified one is an STM and the other is a USM, all my lenses are USM so I don't know what STM means.  That is what I have referred to when I asked which would be correct for the 20D and a housing with a port.  Ikelite makes a port for Canon's 10 - 22 mm lens so my question regarding port availablity was based on the use of existing ports for this new lens.



We identify lenses by their numerical focal lengths.  Currently Canon offers only one lens in the 10-18mm focal, which is an STM type lens introduced in this article.  STM type lenses are designed to allow continuous autofocus on select video enabled Canon DSLRs such as the ones listed in the chart above.  The Canon 20D will autofocus when capturing still photos with the lens. 

Since you referred to the 10-22mm USM lens in your reply I understand better what you are inquiring about.  The 10-22mm lens is also a compatible option for the Canon 20D and as you commented Ikelilte does make the port for this lens.  As for the new lens 10-18mm lens, it will likely require a different port; we have to wait on Ikelite to make an announcement that they will make a port for the lens.  My assumption that due to the smaller design of the new 10-18mm lens, that it will require a new port.

Does anyone know please tell me,

Is this lens it's going to replace the 16-35 there today? Or it will be th place 17-40 is Aperture 4, and getting out another 16-35 new well and she will be with Aperture 2.8?

And it really going to come out 14-24? That has been from 2012 talking about it ..

Thank you.

Canon has not indicated that they are discontinuing the 17-40mm f4 L series lens as of the present time, but the new 16-35mm f4 IS lens could be a replacement for it should that be the case.  As far as any 14-24mm lens goes, Canon has not made any announcements on such a lens.

I doubt Canon will bother with a 14-24mm. The rumors are there largely because of Nikon's lens. My own guess is it that Canon consider the 16-35 a more popular lens and that 14-24 is less likely to be a big seller, as I would suggest is the case for Nikon's behemoth. Having said that, I would have liked a 14-24 f4 IS that would be smaller than the new 16-35, but I doubt it will happen now.

Looks as though they went a step further with the introduction of the 11-24mm f4 lens in May 2015.


I have a canon 60D and I am interested in recording video with the EF-S 10-18mm f/4.5-5.6 IS STM Lens, my question is the STM works with my camera?, thank you.


My best regard

Yes it will work. The kit lens 18-135 is also STM.

It should work on 60D as it is designed for crop frame.

STM lenses including the EF-S 10-18mm f4.5-5.6 IS STM lens are compatible with your 60D camera.  In still photo modes the autofocus is supported.  However for autofocusing with video recording and the 60D, please note:

The Canon EOS 60D pre-dates the STM lens design and bodies which support the full-time Movie Servo AF system (known as the Hybrid CMOS AF system).  When recording video with the 60D, if you depress the autofocus button, the autofocus will deploy, but is not recommended as it might momentarily throw the focus off and change the exposure.  The AF drive type in this camera is not designed to work continuously during video recording so the system may not end up focusing where you want.  As a result, manual focus is the more accurate means of shooting video with the 60D.

The bottom line is the 60D lacks Hybrid CMOS AF system found in the Rebel T4i and other similar bodies designed to work with the STM lenses and focus system.  If recording video with continuous autofocus is a priority, you should consider upgrading to models such as the T4i, T5i, or 70D which have the Hybrid CMOS AF system.

When is Canon going to Quit with the Greed, and Just include the hood with a lens. You pay 500 bucks for a lens, You should get a Hood. Vellos doing great though.
