I use these stores. I can't vouch for ads below.

Let me save you from reading the rest of this review. If you have $1,500, want the best ultra-wide zoom on the planet for your Canon full-frame (5D, 1Ds Mk III, etc.) or 1.3x (1D Mk III) camera and don't mind a little extra size and weight, just get one of these now. It is significantly sharper in the corners over the previous 16-35mm f/2.8, and focuses much more consistently.

After thousands of shots, I couldn't make a technically bad shot with this lens on my 5D. I just kept cranking out winners. Skip to the Available Light and Flare sections to see some examples.

If you only have $700, or prefer smaller and lighter, the Canon 17-40mm f/4 L has optics just as sharp. I've owned my 17-40mm for a year, and just borrowed this 16-35mm II to try out.

When I use any of these lenses, I'm usually using them at the 16mm or 17mm end. 16mm is much wider than 17mm, so I now may go buy this 16-35mm II. I bought my 17-40mm a year ago because it had better optics than the original 16-35mm.

If you have a 1.6x camera (Rebel, 40D, etc.), get the Canon 10-22mm EF-S instead for wide angles, or the Canon 17-55mm f/2.8 EF-S IS if you want f/2.8.



1.) Sharp (better than original 16-35mm f/2.8, same as 17-40mm f/4 L)

2.) Easy operation; just works great and never gets in the way of a great photo.

3.) 7-bladed diaphragm.

4.) Canon USA is discounting the price by $100 from now through 13 January 2008. Canon calls these "instant rebates," which mean immediate discounts with nothing to mail in. At $1,339 (USA) at Adorama, it's the least expensive pro f/2.8 ultrawide zoom I can ever recall seeing.


Bad: Not much, but if I have to find something:

1.) 82mm filter thread (77mm is standard.) You'll have to buy a new filter or two, or I can hold my 77mm filters in front of the 16-35mm temporarily.

2.) If brick walls are your thing, like all ultrawide zooms, there is plenty of distortion at 16mm. Shoot at 21mm and it goes away, or fix it in DxO.

3.) Bigger and heavier than the previous big and heavy 16-35mm. It still isn't that bad, and is a few ounces (100g) less than my 70-200mm f/4 L IS. It's still comfortable to lug my 5D and this 16-35mm II around my neck all day.


Specifications     top

Intro   Specs   Performance   Compared   Recommendations


Canon calls this the Canon Zoom Lens EF 16-35mm f/2.8 L II USM.

   EF: Electronic Focus. All modern Canon lenses focus with a motor in the lens.

   L: Expensive as L. No exact meaning other than this being Canon's lingo for lenses with extra durability and weather sealing. L lenses work on all cameras including film and full-frame digital. Canon puts a red band around the front of these. See also Canon L Lenses.

   USM: Ultra-Sonic Motor: The focus motor operates silently.


Focal Length


Used on a 1.3x camera it gives angles of view similar to what a 20-44mm lens would give on a 35mm film camera.

On a 1.6x camera it gives angles of view similar to what a 26-57mm lens would give on a 35mm film camera. See also Crop Factor.


Maximum Aperture




16 elements in 12 groups.

Three of these elements are aspherical: one is an expensive custom-ground aspherical element, another is a replica (plastic) aspherical element and one is a glass-mounded (GMo) element.

Two elements are made of Ultra Low Dispersion (UD) glass (same as Nikon's ED glass), which helps reduce color fringing.



7 blades.

Stops down to f/22.

It's round until f/4 and heptagonal from f/8.

It gives great 14-pointed sunstars.


Filter Size


In the days of film this non-standard size would mean I'd have to buy another dozen filters just for this lens since today's pro standard size is 77mm, but for digital, all I'd have to buy is an 82mm Tiffen grad ND 0.6. Even a polarizer is optional, since polarizers rarely are appropriate for ultra-wide lenses.


Close Focus

The Canon 16-35mm f/2.8 L II is a great lens that just works. When mine arrived, I took it out and shot with it for two weeks in California's Eastern Sierra and Yosemite before I bothered to pick it apart with any formal tests.

The results for real photos are simply stunning. You ought to see them on a 30" monitor or in print! All I can show on your screen are much smaller vignettes.


Focusing   back to Performance or back to Introduction.

Focusing is excellent in every way. It's much more consistent than the original 16-35mm.


What Moves

The focus is entirely internal. Nothing moves externally when autofocused.


Ease of Manual Focusing

Excellent. Just grab the ring. Manual focus requires no switches.



AF speed, like most wide lenses, is just about instantaneous.


Autofocus Offset

I get dead-on focus on my 5D.


Autofocus Consistency (how often is it in focus?)

I get perfect focus every time on my 5D. This is much better than the original 16-35mm f/2.8, with which I got a disturbing few percent of images that were simply out of focus, even though the AF system confirmed that it was locked on.

We pay for the speed of the Canon AF system in that a small percentage of shots, even when the AF system confirms perfect focus, are simply out of focus. Nikon may be a little slower, but it never misses.

The percentage of misses varies with lens and camera, from 100% OK, as I get with this 16-35mm II and my 5D, to several percent bad, as I get on my Rebel XTi and some other lenses as mentioned in their respective reviews.


Focus Breathing

Breathing is a motion picture term which refers to what happens as you pull (change) focus from near to far while the camera and subjects remain in the same place. I list this for people putting these lenses on their Canon XL-1s for shooting video.

At 35mm there is no breathing.

At shorter settings like 16mm, the magnification reduces as one pulls focus closer. This is the opposite from most traditional lenses. Also, with a fixed camera and subject, the distortion becomes more barrel as one pulls focus closer.


Available Light    back to Performance or back to Introduction.

f/2.8 lenses are more than fast enough for hand-held night shooting with digital cameras. f/1.4 lenses are for shooting my favorite ISO 50 Fuji Velvia.

With digital cameras, ISO 3,200 is eminently usable, and even f/5.6 lenses are fine.

Here's a hand-held grab shot:

Redwood Motel, Bridgeport, California

Redwood Motel, Bridgeport, California. (at 25mm, 1/6 of a second at f/4, hand-held, ISO 3,200, 5D.)

25mm and 1/6 of a second at f/4.

Unsharpened, unaltered crop from center at 100% (44" [1.1m] wide print).

And here's another hand-held shot while having dinner:

Rhino's Bar and Grill, Bridgeport, California

Rhino's Bar and Grill, Bridgeport, California. (at 16mm, f/2.8 at 1/5 second, hand-held, ISO 800, 5D.)

Rhino's Bar and Grill, Bridgeport, California

Unsharpened, unaltered crop from bottom right at 100%. (44" [1.1m] wide print).

This is a huge improvement over the original 16-35mm f/2.8, which got very soft and fuzzy in the corners at 16mm and f/2.8.


Lateral Color Fringes

back to Performance or back to Introduction.

This lens is approved by the PPLFPA, Professional Patio and Lawn Furniture Photographers' Association, with a grade of "A-."

You really have to go out of your way to see any, and even if you do, they are only at the widest end. There are none at the longer end.

Color Rendition   back to Performance or back to Introduction.

I see no differences from my other Canon lenses.


Construction Quality

It has a rubber gasket on the lens mount to keep crud out of your camera.



Plastic and metal.


Filter Threads and Hood Bayonet

Anodized aluminum.

Filters have a tendency to unscrew themselves from these metal lens threads, so keep checking to be sure you don't lose any.

Distortion   back to Performance or back to Introduction.

Wide angle lenses are supposed to stretch round things, like people's heads, out towards the edges of the frame . This sucking is why we love ultra-wide angle lenses.

Straight lines should always remain straight. When they curve slightly, that's the undesirable distortion of which I speak.

The distortion of the Canon 16-35mm II is typical for any ultrawide zoom: complex barrel distortion at the widest end and pincushion at the longer end.

If you waste your time shooting brick walls straight-on, an ultrawide is the last lens you'd want. Like most ultrawide zooms, shoot in the middle of the range to get the least distortion. Shoot the Canon 16-35mm f/2.8 L II at 20mm and the distortion goes away for shooting straight lines parallel to the frame edges.

The proper way to shoot walls is at an angle, in which case distortion is invisible:

Lee Vining Market

Red Market, at 16mm.

If you shoot head-on, you'd better make sure it's an interesting wall. Shoot at 21mm and there's no problem.

Lee Vining Market

Red Market, at 21mm.

Brick walls worth shooting are rarely straight.

Lee Vining

Brick wall, at 21mm.

If you're silly enough to shoot a blank wall straight-on at 16mm, you'll get this:

Wall of Shame at 16mm.

0.0: none.
-1.2 pincushion.
-2.1 pincushion.
-2.0 pincushion.

Even after this simple correction in Photoshop, some waviness will remain if you're looking for it. If this is you, use DxO for better correction.


Ergonomics   back to Performance or back to Introduction.

Excellent. Nothing gets in the way of a great photograph.

There are no switches required for macro ranges or manual focus.

The only switch on the 16-35mm II is a switch marked AF-MF, but manual focus is available any time you grab the focus ring. The switch's only purpose is to deactivate AF when set to MF.

It's a good-sized lens, but lighter than it's Nikon 17-35mm f/2.8 counterpart. The Canon 16-35 II is actually quite light when used on the all-plastic Canon EOS Rebel G, and delivers great results.


Exposure Accuracy   back to Performance or back to Introduction.

Perfect, no problems seen.


Eyeblow back to Performance or back to Introduction.

None: no wind blows out the eyepiece as I zoom.


Falloff (Darkened Corners)

back to Performance or back to Introduction.

I saw no falloff in any of the thousands of real photographs I made with the 16-35mm II, even at 16mm at f/2.8 in dark interiors.

If I deliberately look for it, yes, it's got a lot of falloff at 16mm at f/2.8. Otherwise, I never noticed it.

The shots below of an Expodisc greatly exaggerate falloff. I never saw this in thousands of real shots.





Use on 35mm Cameras    back to Performance or back to Introduction.

Perfect. It's designed for 35mm film and full-frame digital.


Use with Filters   back to Performance or back to Introduction.

It works perfectly on full-frame with any traditional old, thick filter. I tried it with my 7.2mm (0.28") thick traditional Hoya polarizer.

There is no need for expensive thin filters.

You will get some vignetting with two thick stacked filters. Zoom to a longer focal length if you insist.

As you can see below, I was able to drop my 77mm circular grads into the front of the 16-35mm II and hold them with my fingers. When I did, I got no vignetting even at 16mm, except if my fingers got in the way!


Flare and Ghosts   back to Performance or back to Introduction.

You really have to push the 16-35mm II to get ghosting. You can do it, but you're on the verge of going blind. All these shots were made with completely uncoated Tiffen glass filters, either a two-stop grad or an 812. The Tiffen 812 filter is a mild warming (magenta/amber) filter. I used it because it was the only 82mm filter I had handy to protect this borrowed 16-35mm lens.

Canon 16-35mm II flare

Dawn, Yosemite Valley. (at 25mm, f/11, uncoated 812 filter)

The two examples above were extreme. In most cases, just move an inch (cm) either way to hide the sun a little bit more behind a leaf and the problem goes away.

Blinding glare, Bodie. (at 16mm, f/11, uncoated 812 filter)


Sharpness  back to Performance or back to Introduction.

Sharpness is excellent. Sharpness is the same as my Canon 17-40mm f/4 L, which is also excellent.

Conway Summit

Unsharpened crop from left side of 100% full-frame 5D image from Conway Summit above. This is equivalent to a crop from a 44" (1.1m) wide print. (at 28mm, f/5.6, 1/60, had-held, uncoated glass 0.6 ND grad.)

When compared to the Canon 17-40mm f/4 L, which lens is sharper depends on which corner you are comparing! Normal slop in the position of zoom lens elements means sharpness will vary from shot-to-shot and corner-to-corner more than any sharpness difference between these two lenses

This 16-35mm II and the 17-40mm L are much sharper in the corners at wide settings and larger apertures than the original 16-35mm f/2.8 L, which was awful at 16mm and f/2.8 if you were looking hard. The original lens, designed in the days of film, could be so sloppy in the corners on digital cameras if used improperly (shot at f/2.8 for sharpness tests) that many people mistakenly thought their lenses, or Canon's full-frame cameras, were defective. In fact, it was the photographers who were defective.

Diffraction is usually the sharpness-limiting factor for all lenses, especially digital SLRs, at about f/11 and above. See also How Sharpness Varies with Aperture.

It's also extremely sharp on 35mm Fuji Velvia 50, as well as digital.

My particular sample has what seems like the usual manufacturing variation, and has its field shifted a little such that if its focused at infinity on the right, the left side is focuses a little closer at 16mm.


Sunstars   back to Performance or back to Introduction.

Canon 16-35mm II Sunstars

Dawn, Mono Lake Picnic Grounds. (at 16mm, f/16, uncoated 812 filter)

I love the 14-pointed sunstars caused by the 7-blade diaphragm. The effect is strongest at small apertures like f/16, and less at large apertures like f/4.


Zooming   back to Performance or back to Introduction.

The zoom range is evenly-spaced along the zoom ring. It's trivial to set precise composition holding the camera in one hand and using one finger to zoom.


Zoom Creep



Focus Shift while Zooming

I can't see any focus shift. Feel free to zoom after you've focused.


Focal Length Encoding Accuracy

The EXIF data agrees with the settings marked on the lens at 16, 20, 24 and 35mm.

I have not correlated the accuracy of the markings with actual focal lengths.

Recommendations     top

Intro   Specs   Performance   Compared   Recommendations

For a 1.3x, full-frame or film cameras, just get one of these. It's lighter than you think for such a fat lens.

Canon USA is knocking $100 off the price from now until 13 January 2008, so just get one if you're contemplating it. I doubt anyone will be disappointed. This new 16-35mm II is much sharper in the corners at 16mm and f/2.8 than the previous 16-35mm f/2.8, and it focuses much more consistently.

If this 16-35mm II was available in 2006 when I bought my Canon 17-40mm f/4 L and 14mm f/2.8 L, I probably would have bought this 16-35mm II instead. The significantly wider 16mm setting vs 17mm may have saved me having to buy the $1,800 14mm f/2.8 L with which I can't use filters.

I'm a sucker for a deal, so I just may buy one of these for myself anyway. I borrowed the one I reviewed here.

If you aren't as addicted to the 16mm end as I am, the Canon 17-40mm f/4 L is just as sharp, weighs less and costs half as much.

For a 1.6x camera, get the 10-22mm EF-S instead for ultrawide, or the Canon 17-55mm f/2.8 EF-S IS if you want f/2.8.
