The Canon EF 17-35milimet f/2.8 L is a lightweight full-frame f/2.8 professional ultrawide zoom for all Canon EOS digital & 35milimet autofocus cameras. It"s the same form size as today"s Canon 17-40milimet f/4 L, but built tougher and a stop faster.

This 17-35mm has instant manual focus override simply by grabbing its focus ring at any time.

Used on a modern camera lượt thích the Canon 5D Mark III with a lens profile loaded, any color fringes are corrected in-camera. This gives better image chất lượng today than we ever could get with this lens when it was new.

Compatibility & Formats

This lens is optimized for 35milimet film & full-frame digital, & of course works on all 1.3x and 1.6x Canon cameras.

This Canon EF EOS 17-35mm f/2.8 works perfectly with every Canon EOS camera ever made, meaning every Canon DSLR & every Canon autofocus 35milimet camera made since 1987.

This means of course it works great on today"s 5D Mark III & Canon 7D, but it works just as well on my original Canon EOS 620 from 1987!

As a full-frame lens, this works on all Canon SLRs, regardless of format. As a full-frame lens, I will be reviewing this lens on full-frame.

Canon calls this the CANON ZOOM LENS EF 17-35mm f/2.8 L ULTRASONIC.

EF means "electronic focus," meaning that there is an autofocus motor in the lens itself. All Canon lenses since 1987 have sầu been EF.

L means expensive sầu as L.

ULTRASONIC means USM, which means you may grab the focus ring at any time for instant, silent manual focus override.

OverallAutofocus Breathing Màu sắc Distortion

Ergonomics Falloff Filters Flare Lateral màu sắc Fringes

Mechanics Sharpness Sunstars

Overall performance top

The Canon 17-35milimet f/2.8 is a well-made, great-handling, lens with optics easily corrected electronically in Canon"s newest cameras.

Autofocus performance top

Autofocus is as we expect from Canon, maybe on the slow side for an ultrawide simply because it isn"t instantaneous.

Auto/Manual Switching

Just grab the focus ring for instant manual-focus override.

You never need lớn touch the AF-MF switch unless you want to lock-out autofocus.

AF Speed

AF is relatively leisurely for an ultrawide lens.

AF Accuracy và Consistency

AF accuracy is fine on my Canon 5D Mark III.

Manual Focus

Manual focus is easy; just move the ring.

Focus Breathing performance top

Focus breathing (the image changing kích cỡ as focused) is mostly of interest lớn cinematographers who don"t want the image changing size ("breathing") as the lens is focused aý muốn different subjects.

The Canon 17-35mm f/2.8 has almost no focus breathing. The only weird thing I see is at the wide over that the center of the image doesn"t change, but the sides cave-in a bit as focused more closely. In other words, at 17mm, if you have two vertical lines on each side of your subject, their tops will move closer to lớn each other as focused more closely!

Color Rendition performance top

The color balance of this 17-35mm f/2.8 matches my other Canon EF lenses.

Distortion performance top

This Canon 17-35mm f/2.8 has some distortion at every setting: barrel at 17mm & pincushion at 35milimet. It"s complex, so it never fully corrects with simple tools, but you can correct it with some of Canon"s software, or in-camera with the 5D Mark III if you shoot CRW raw và then stop & convert lớn JPG in-camera in the PLAY menu.

The distortion can be obvious at the ends of the zoom range, but rarely in the middle.

Use these values in Photoshop"s Lens Distortion tool lớn remove most of it:

** Waviness remains.

For less distortion in an ultrawide zoom, chose the Canon 20-35milimet f/2.8 L (1989-1995), which has less distortion than any of today"s Canon ultrawides.

Ergonomics performance top


Canon 17-35/2.8. enlarge.

Ergonomics are the same as Canon"s newest Canon 16-35mm f/2.8 L II và Canon 17-40mm f/4 L.

The zoom flicks easily, with little to lớn no damping.

The zoom range is a little congested at the 17milimet kết thúc.

Falloff (darkened corners) performance top

Falloff is never visible with Peripheral Illumination Correction enabled, an option in the Canon 5D Mark III, Canon 5D Mark II and others, presuming you have sầu data for this lens loaded inlớn your camera.

I"ve greatly exaggerated the falloff by shooting a flat gray target and presenting it against a gray background.

Filters, Use with performance top

There"s no problem with vignetting even with thichồng or rotating filters, but don"t push your luck: you"ll get vignetting on full-frame at 17mm if you staông chồng filters.

The filter threads don"t move sầu.

My Hoya HD polarizer works fine, but don"t use polarizers on ultrawide lenses.

Gels can be cut and slipped into a slot over the rear element.

Flare và Ghosts performance top

The 17-35 has almost no ghosts if you get the sun in your image. If you do, there may be a dot or two opposite the sun if the conditions are just right.

Lateral màu sắc Fringes performance top

Used on a modern camera lượt thích the Canon 5D Mark III, which corrects color fringes in-camera when a lens profile is loaded, there are no color fringes. Hooray!

Mechanics performance top

Sharpness performance top

Lens sharpness doesn"t matter much, but it sure distracts amateurs who confuse lens sharpness with picture sharpness.

In the center, the 17-35mm is always super sharp at every aperture. It"s the same in the center as Canon"s newest 16-35mm f/2.8 L II and 17-40milimet f/4 L.

On my 5D Mark III which correct color fringes, it"s about as good at the sides & corners as the older 16-35milimet L. It"s not quite as good as the newest 16-35milimet f/2.8 L II and 17-40milimet f/4 L, but none of these lenses are all that great wide-open in the corners anyway!

Unless you"re a pixel-counter, I wouldn"t worry about it. Far more of an obstacle to lớn sharpness is that ultrawide zooms vary from shot-to-shot and sample-to-sample, & their planes of best focus are rarely planes, and often tilted! Spover too much time trying khổng lồ compare ultrawides, & you can go crazy.

If you worry yourself sick about sharpness, get the 16-35mm f/2.8 L II or Canon 17-40mm f/4 L, or just stop down to lớn f/11 with any of these lenses for much better results.

Sunstars performance top


At f/22.

With the somewhat curved blades of its 7-bladed diaphragm, sunstars are muted.

This is as much as I can get, & this is at f/22. The stars are asymmetrical 14-pointed.

AF - MF Switch

Leave this in AF.

Set it to MF only to deactivate autofocus.

Focus Point

I haven"t had any problem with this lens, but with my other Canon ultrawide zooms I usually get the most accurate focus with the center AF area.

This 17-35milimet is lighter than any other Canon f/2.8 zoom, & performs almost as well as the newest.

Get one, I did, & I already own the 16-35mm L II & 17-40milimet. I lượt thích having f/2.8 in the same compact size as the 17-40mm!
