Canon Lente 17-40mm f/4L USM USA

Comments about Canon EF 17-40mm f/4L USM Lens:

As I use a Canon EOS-1D Mk 1V most of the time, this particular lens gives me an effective working range of 22-52mm, making it a very versatile short focal length zoom. As the 1.3x magnification factor allows me to utilize the center of the lens, I have no trouble with any image quality fall-off in the corners. I find it a very well made lens in the L series tradition, and now wonder why it has taken me so long to get around to buying one. To me, it seems far better value than the double-the-price 16-35mm f/2.8L unless you really need that extra stop. A cracker of a lens.

I was very close obtaining the faster f/2.8L, but elected purchasing the f/4L... I could not be any happier with this lens, in fact I Love it!!!

Comments about Canon EF 17-40mm f/4L USM Lens:

- I use it for architectural shots
- Both night and day
- Hard to focus, but can do it manually, since you should be in the first place
- Very reliable for the price you pay

I use this lens with a Canon 5Dmk2, shooting 1080p video "beauty shots" on lakes and ponds, rivers and streams. I am totally pleased with the footage I'm getting with it... My other main lens is a CANON EF 70-200/4L IS USM, which compliments the 17-40 nicely.

Cannon lenses never fail on me!

This lens delivers beautiful results. I originally had my eye on the 16-35mm 2.8L however the price of that one is just too outrageous. This lens is the best value in my arsenal. I also recommend the Hoya 77mm (Moose) Warm Circular Polarizer Glass Filter with this lens.

work as a photographer and I love the new lens. Very soft! I am eager to try on a fullframe, where the opening is fantastic!

Im used for everything places,arquiterus and stills lifes.Its very good results all the things to do.

I was very surprised with the quality of this lens, it's actually sharper them my 70-200 and 24-70, I use it mostly for landscape and bmx photography, I don't normally use uv filters i normally just use the lens hood but i think a filter is a must to protect this lens.

I have had this lens for about 3 months now. I got it right before a trip to Yellowstone and surrounding areas. It proved to be very useful. Previously, I had the Tokina 11-16 2.8, but I quickly discovered I was not happy with the outcome. I also had the 28-135mm lens - which overall was great, but couldn't get quite wide enough on my 7D. Of course I contemplated the 16-35 2.8, but I wanted to invest that extra 800 bucks elsewhere.
I have found this lens to produce great images. I use it mostly for landscape work. There is significant distortion even on a 1.6x crop camera, however some can be fixed in post processing and some kinda looks neat...and considering a tilt shift lens is about 3x the price, you learn to live with it.
I have not found much need to have IS with the lens. Handheld at 1/40 can produce good results. I usually bump up the ISO a bit if I need to keep the aperture fixed so that I don't have to use slower shutter times.
I have not found many instances where I wished I had gotten the 10-22. I think that is a whole different comparison. As I said, 17mm is usually wide enough. I don't have any problems photographing cars at that focal length (I sure did with the 28-135 - had to be too far back and people always got in the way).
I recently used it in the Crystal Caves at Sequoia NP, along with the 580EX II flash and got pretty darn good results at ISO 400; f/5.6; 1/60; and autofocusing.
Overall, I am really happy with this lens and have no intentions of getting rid of it.

This lens is better than I anticipated. I wanted the 2.8 but didn´t had the money. But this one is very good.

Comments about Canon EF 17-40mm f/4L USM Lens:

Purchased largely for landscape shots with my 1DMKII. Did alot of research and am happy and pleased with it.

Comments about Canon EF 17-40mm f/4L USM Lens:

This lens is perfect for all purpose use. The only reason I gave it 4 stars is that it is an f/4--I really wish canon made a 2.8 version.

Comments about Canon EF 17-40mm f/4L USM Lens:

I am an advanced amateur that does a little freelance work on the side and I have been looking for a wide zoom to pair with my 7D. I was looking at the 10-22 EF-S but wanted to future proof my lenses for a FF so got this instead.

I have been very pleased indeed with the results. Colour reproduction is good, my copy is sharp right throughout the range and it is built like a truck.

Focusing is quick and accurate and I love that it is all internal movement - very handy when it spends a fair bit of time outside. L glass is great for its weatherproofing and this is no exception. It is surprisingly good up close as the minimum focal distance is very short.

My biggest gripe is the f/4, if it was only 2.8 I would be ecstatic.

I would recommend this to anyone and although it is nowhere near as wide as the 10-22, the other feature make it well worth it.

This lens is currently being used on a 40D that is about to get upgraded to a 7D. I have owned and used a number of lenses on my 40D.

At first, I used the 18-55 mm kit lens but upgraded to Tamron's SP 17-50mm F/2.8 lens. I loved this lens – it was small and light with excellent image quality. However, living in a humid, subtropical place and using it in more challenging conditions (sometimes in wet weather), I put it away for a few weeks only to pull it out again and find it full of fungus. It then went straight into a dustbin.

Then I got the 24-105 mm L lens, and while I found it excellent for people photography, on a crop camera it was rather too long for landscapes and much outdoor photography.

The 17-40L offers bullet proof build quality, and focal length changes entirely within the sealed casing, enhancing dust and water resistance. By the way, although claimed to be dust resistant, I was surpised during my ownership to find the 24-105 mm L, even with a filter, was not entirely so. For genuinely high dust environments the EF 17-40 is a better option.

17-40L image quality is excellent, comparable to the 24-105 mm and probably slightly better than the Tamron 17-50 mm. It is better value for money than the EF 16-35 mm f2.8 L II USM, but somewhat of a niche lens on a camera with an APS-C size sensor. It is best best purchased for this format in the following circumstances:

• When one is looking for a professional build quality, wide angle to close to standard zoom range lens, especially if needed in high dust or moisture environments.

• When most of your photography is out-of-doors, and people and portraiture are not your primary subjects, and image stabilization is a bonus rather than essential.

For me this is the case, so this is going to be a keeper lens. However, if this does not apply to you, then Canon's better quality EF-S standard zooms are better options. If looking for a L standard build quality in a 'people' lens, then the EF 24-105 mm L is recommended, and its image stabilization is a great advantage in low-light environments.

It is unfortunate that the EF 17-40 L is not image stabilized, but as this is after all intended as a wide angle lens on a full frame camera. It is unfortunate that Canon's professional grade lenses are intended for full frame platforms, as many enthusiasts will stay with APS-C sensor cameras but would buy a L quality, standard zoom EF-S lens, if this were available.

one of the great L series lens with reasonable price. very sharp and great focus

Comments about Canon EF 17-40mm f/4L USM Lens:

Purchased this lens to replace a Tamron 11-18mmm 4.5-5.6.

Obviously the Canon is a much more superior lens in all aspects.

Build quality is very nice and it's got a nice weight to it. Not heavy, but has a solid feel to it.

Since I'm shooting with a crop body(7D), only thing I wish was different would be it being a wider lens such as a 14mm or so and a little faster for low light situations.

The 16-35 2.8L from Canon would be closest to that range but over double the price so my funds only allowed me this lens for now.

Overall, I am very happy with the lens
