Digital Cameras Photo Reviews of Canon EF 17-40mm f/4L USM Ultra Wide Angle Zoom Lens for Canon SLR CamerasCustomer Review: Value, quality and lightweight Summary: 5 Stars
Having owned the distortion-prone Nikkor AFS 17-35 f2.8D for six years, it was time to switch over to Canon's EF 17-40 mm f4L USM. Canon's version was over a $1000 cheaper, optically superior and lighter in weight. For me, an outstanding standard lens when coupled with the Canon 5D.
Vignetting at f4 is minimal. Adobe Photoshop CS2's vignetting tool can correct the vignetting.
Distortion at 17mm is minimal. Less than Canon's EF 16-35 mm f2.8L USM set at 16 mm.
With the 5D pointed at a blue sky, the EF 17-40 hunted for a focus point while the EF 16-35 didn't.
Flaring is minimal when compared to the EF 16-35.
Portraits taken at 40 mm produced better results than the EF 16-35 and AFS 17-35 at 35 mm.
Images produced at f4 are sharp. At f8, the images are very sharp.
This lens is a definite keeper.
UPDATE (13-July-2007): Please see some of the images taken with this lens.
Customer Review: Such A Solid Little Lens Summary: 5 Stars
My school owns this lens, and after using it, I realized that I had to have a copy of my own.
I recently purchased a 1d Mark II N and I also got the 17-40 L to go along with it. (Take Into Account The 1d2n has a 1.3x Crop factor, not 1.6x like the 10d, 20d, 300d, etc)
To start off, I've had my share of lenses and this lens stands up among the rest as being one the best. Solid, fluid USM with the ability to manual focus while in autofocus. (full time manual focusing)
(...)
Pros: Size (it's solid, but light compared to the sigma 24-70 2.8), USM, comes w/ lens hood and lens pouch, sharpness, color, contrast, sharp even wide open at f/4, very wide on the 1.3 crop body (as wide as my old 15mm fisheye on my old 1.6 crop body)
Cons: Little pricey, f/4 can be a little tedious in low light
Overall: This is an excellent lens. I love its size and I can feel confident shooting with it wide open.

Customer Review: Excellent quality and amazing pictures Summary: 5 Stars
I have had this lens for almost a year now. I bought this with a 350 XT body only. For a long time this was my only lens and pretty much this is all I needed.
I have used it extensively, the contrast and sharpness are great, it is relatively fast and extremely reliable, the success rate with this lens is excellent. The outdoor scenic shots are breathtaking. For the money this is the best wide angle lens you can buy.
Compared to the 2.8 's it is way less expensive and easy to carry. The 2.8 to 4.0 gap can easily be covered by changing settings on the XT in most cases.
Also it gives a nice grip when held from the lens and this results in steady shots at high ISO settings. I have used it for nightshots, the shutter speed has to be slow to get the shot, got good and sharp results with the lens.
I have added a 50mm 1.4 prime lens to my collection but the 17-40mm is the one I have on most of the time when going out.
Customer Review: After a 18-55 f/3.5-5.6 IS, a great upgrade. Summary: 5 Stars
I picked this over the 17-55 f/2.8 IS because of its lower price and L-series construction. Theses lenses are intended for different uses, though. I don't need a lens that fast.
Never used the 17-55 f/2.8 IS, but both versions of the 18-55 (II, the XT & XTi kit lens; and IS, the XS, XSi, etc kit lens) and this lens is a beast in comparison to those. Amazingly solid construction, fixed-aperture, sealing, fast USM (which makes no big differences on Wide Angle lenses, but in noise does) and FTM are pros on this lens. I will not review optics, you can find websites on that much more detailed than here.
On the other side I must say the hood included doesn't seem to be very effective, because it's so shallow. It makes polarizing easier - eyes on the viewfinder, one hand on the grip/shutter button and the other rotating the polarizer. No tripods or snapping hoods on and off.
I love this lens and would defintely buy this again.
Customer Review: Great general lens for a digital SLR Summary: 5 Stars
If, like me, you are a fan of wide angle shots with their greater sense of depth, and encompassing vision, then you will love this lens.
The 1.6X multiplier of my Rebel XT takes away the extreme wide angle capability of this lens, but nevertheless the range is impressive at an effective 27 to 64mm. This makes the lens a very effective general purpose lens, ranging from a great wide angle to slight telephoto. I normally leave this lens on my camera, only swapping it for a telephoto zoom for outdoor/sports shots.
The quality is just great - the pictures jump out at you for their color, contrast and sharpness. Even though this lens costs almost as much as the camera body, there is no question that it is worth every penny. If you are thinking of buying the new 30D with a lesser lens, then you might want to consider saving the money on the body and splurging on this lens instead.
You won't regret it!
