The EF17-40mm f/4L USM is an ultra wide angle Canon EF zoom lens meant for professional and high amateur SLR EOS camera users. While it is an excellent lens when used with an analog SLR camera, the EF17-40mm f/4L USM is especially well suited for digital SLR cameras with an imaging sensor size smaller than the 35mm format. Indeed on such digital SLR cameras these focal lengths can give an angle of view approximately equivalent to that of a 28-70mm lens used on a 35mm camera, which makes it the ideal standard zoom lens.

The EF17-40mm f/4L USM has 12 lens elements arranged in 9 groups. Super Spectra Coating on the elements ensures excellent color balance and minimizes ghosting and flare. To provide superb image quality over a 17-40mm zoom range the lens uses three aspheric elements of two different types, while Super UD (Ultra-low Dispersion) glass is used to prevent the chromatic aberrations that often can degrade the subject edge clarity.

Minimum focusing distance is just 28mm throughout the entire zoom range. The Auto-focus works silently and quickly thanks to a fast central processing unit with an improved AF algorithm. You can override AF mode with manual focus should you wish. Controlled by an electromagnetic diaphragm, the EF17-40mm f/4L USM's circular aperture can achieve a more attractive appearance to out of focus background areas in a picture. The front of the lens does not rotate as you focus. This means, for example, that polarizing filters still function effectively as you zoom in and out. At the rear of the lens there's a drop-in gelatin filter holder. Highly resistant to moisture and dust, the EF17-40mm f/4L USM is ideally suited for use in harsh environments. Environment friendly lead-free glass is used throughout its construction.

5 out of 5 eggsAwesome lens

Pros: Great detail and color in photos really can't ask for more here.
I am a novice in the full frame camera world but I have to say this lens does everything I ask of it.

Cons: Slow focus time and sometimes the lens can't focus at all if what you are looking at lacks enough detail to get the right sharpness. Zoom is very small and basic but decent for close ups.

Other Thoughts: This lens is well worth the price and I hate paying high prices for things. I would give this lens a 9/10.

5 out of 5 eggsBest Bang for your Buck

Pros: *IQ is very good
*Very sharp pictures
*Great colors
*Inexpensive "L" lens
*Makes a good walk around lens for crop sensors
*Focus is very fast
*USM makes thing silent
*Comes with a carry bag
*Comes with a lens hood
*Good bokeh
*Great for landscapes and panorama pictures
*The "L" lenses have the best quality of any lenses out there. Will never go back to 3rd party lenses

Cons: *No IS (but you don't need it cuz this is not an indoor lens)

Other Thoughts: This my 2nd 17-40L lens. I sold my first one a year ago and missed it dearly so I bought another one. Canon "L" lenses retain about 95% of their initial price so you can always sell them for what you pay for them.

For those of you who are looking for an indoor lens, you gotta spring for the 16-35L Mk II which is twice as much, but with flash, this makes a wonderful lens indoor.

This lens will make you want to buy more, better lenses. Another good starter lens is the 70-200L F4. It's about the same price if not cheaper than this lens.

You better start selling your arms and legs now to save up for your collection. The 24-70mm is next on my list.

5 out of 5 eggsPerfect.

Pros: I've been a photographer for over 20 years, not that years make anyone any good, but, I've seen gear come and go.....I don't want to see this lens go any time soon.

It's simply awesome.

I've been reluctant to get the wide L's for a while, well, you know how long. Canon's zooms are stunning, however, I hadn't read any reviews which stated what I was looking for in a wide. That of low lens flair, nice bokeh, sturdy and pin sharp...kinda like that perfect job - where you sleep in your own bed all day, party all night and get paid for simply existing...hard to find.

I'm so glad I didn't take any of the "experts" too seriously when it came to swapping out my 'pond marinaded' wide sigma.

This lens ticks all the boxes for me; I'm amazed it's only $699, and more than a little surprised to find it in stock on newegg rather than anyone else. I'm not a great fan of the hurts to compliment them. :-)

The lens is perfect...for my needs.

Now to find that job....

Cons: It doesn't come with a free massage.

Other Thoughts: I have so many thoughts, although, none pertinent to this lens.

World hunger, I'm-a-dinner-jacket's atomic ambitions (I think he's over compensating for being a bit of a botty bandit), how to move some of my belly fat to my upper torso and derier...the list goes on.....

I guess if the mensa club of Iran succeed with their bomb, I have a lens wide enough to get the whole mushroom cloud in view, but, I'm gonna have trouble with the's gonna get bright I'm thinking.

Off to get some factor 50,000 sun cream....and then to for a ticket to the 'Mental East'...

Have a good one!

5 out of 5 eggsDurable and Precise

Pros: I bought this lens with an xti body, avoiding the kit lens, on the advice of an insider in a large photo dealer (I usually buy from NewEgg but this time went over to the dark side). Pros: the price, the quality, the sharpness and durability. It has all that a quality lens could offer and maybe even more. I bought this Canon "L" series lens because I was going to be shooting in Dubai and Egypt for a corporation's publication and advertising. I had ruined more than one camera shooting in locales near deserts (unbelievable how fine that sand gets), my last being a Minolta film camera and auto-focus telefoto lens sacrificed to the Takla Makan desert in western China.
I had fears about the new Canon, since I paid over my mental budget and did not want to sacrifice it to the desert sands. Joyfully, it survived two sandstorms and the dust and pollution of Cairo without a mark (I kept a filter on the front at all times). A polarizing filter helped to cut through the haze considerably.

Cons: The usual: it is heavier than some of the more compact lenses, I miss the telephoto range, I would like a faster aperature. None of these thing matter considering the advantage of taking my camera without fear from desert to jungle to the REALLY challenging weather of a Brooklyn Spring.

Other Thoughts: The lens performs well indoors and out, no problem using a primitive 220EX flash with a diffuser. I don't use the lens hood so I can't comment on vignetting. Sharpness apparent when I enlarge a shot on PhotoShop--who needs a telephoto?

5 out of 5 eggsGreat lens

Pros: Crisp, Clear, Fast AF, well built/weather sealed.

Cons: None

Other Thoughts: This is a great lens. I've used it on my old XT and now my 40D with outstanding results. It's best use is outdoor or in bright indoor light.
Indoor use will require a flash, high ISO or a slow shutter speeds/tripod.
If you want a faster lens (F2.8) for indoors/hand held work on a 1.6 crop sensor go with the Tamron 17-50 or 28 – 75 (Tamron cons, less consistent AF, no weather sealing).

5 out of 5 eggsAwesome

Pros: its ones of the sharpest lenses canon makes, whats there not to like?

Cons: aperture, but if it was any lower it would cost easily over $1000

Other Thoughts: i've put this to use numerous times in automotive photography and has served me well so far.

5 out of 5 eggsGreat Lens

Pros: I use this on my 40D and after getting it I hardly use any other lens. The zoom and focus rings turn nicely and there is no zoom creep. Using this lens on a crop body, aka all rebels and 10D-50D, makes this lens a 27-64mm perfect for indoor use. The build quality is very solid. I have had this lens rained on with no problem. Image quality is excellent.

Cons: Some might say the lens is too heavy especially if you are going from the 18-55mm kit lens but I think it is well worth the weight. My not be a con but I have not had much time with this lens outdoors but indoors I usually use my 550 EX II flash since this lens it not very wide but it has very good results.

Other Thoughts: this is one of the last lenses that I purchased for my photo gear and I only wish I would have done it sooner. Don't worry about the price, just get it and you will be happy you did, I am. Besides It is one of the cheapest "L" lenses canon makes and there is a huge in build quality and optical quality between the consumer and "L" Lenses.

5 out of 5 eggsAwesome Lens

Pros: The zoom and focus rings are very smooth turning. There isn't any slip in the movement or any hangups. Also with the auto focus on, one can override it and manually focus, which is nice. I like that the lenshood has a lining that catches lint, helping reduce dust and lint of the lens and filters. The internal focusing is also a plus for me.

Cons: I don't have a use for the gelatin filter holder.
It's not really a lens you can put on the camera and use all day for everything.

Other Thoughts: It is a heavy lens, but it is very durable and well made. I've used this lens on humid days and rainy days, so its gotten wet. But I have had no problems whatsoever. The quality of this lens is excellent. I compared pictures taken with this lens and the kit lens from my XTi and, obviously, the pictures taken with this lens were crisper and more saturated.
