Customer Reviews:

  • Fantastic Lens.
    This is my first L lens, and i am very happy to own this. sharp pictures, Light weight. I have now ordered another 70-200 F4L after seeing, how good the L lenses are.

  • Good lens, typical L quality
    It's a great lens and a good value in the L lens category. Once you have an L lens it's hard to settle for less and this is no exception....more info
  • My best lens
    These are the best lens I have, if it works this way I can't imagine the outcome of the 16-35. The 17-40 lens takes a lot of detail and for what it does is not that expensive. I recommend this item for anyone interested in not betting that much (16-35) at the moment. ...more info
  • It's really nice, but...
    this lens is my first L, and i was hoping to be blown away. perhaps that was my own mistake for setting my expectations too high. don't get me wrong, it's a great lens, and it does everything i need it to do very well, but i could have gotten a lens for $300 cheaper that would do the same at about the same quality. one thing i do really like is the ultra fast, ultra quiet auto focus. the design is very sturdy, and it does take some great shots. honestly, though, i keep returning to my <$100 50mm to do the serious shooting. ...more info
  • nice lens
    This is a nice lens. It should be for it's cost but it's an "L" so that is expected. I almost only buy "L" lens anymore because they are so good. I don't get as many as I used to but quality has it's price. I have been a Canon user for 35+ years and they are better than ever....more info
  • Simply worth it
    I bought this lens to replace the kit lens I got with my RebelXT, all I can say is that it's worth every dollar i paid.
    Sharp, fast Auto Focus, great build, looks good, feels good and delivers the quality image I expect from an "L" series lens. This is my second "L" lens and both have delivered handsomely....more info
  • Great Lens and very sharp
    I have had this fabulous lens for 2 months now. This is my second lens in Canon's line up of L lenses. I have a 70-200 f4 non-IS also. This is my first wide angle zoom L lens and i have come to know what i have been missing. Till now the widest lens i had was a 50mm f2.5 macro and 50 f1.8. Although on a 1.6x sensor like 20D which i own, this lens is not so wide it performs excellently. The focusing is very fast, sharp crisp images and consistent quality as the aperture range remains the same throughout the entire zoom. This may not be suitable for some the semi-pros or pros since its a little slow being f4, i would recommend this to anyone who does serious photography as a hobby. In indoors too it performs flawlessly. Most of the time i dont use a tripod and its difficult to maintain a fast enough shutter speed especially with aperture more than 8. so if you are like me, then you may want to take a look at the 17-85 IS or the 17-55 IS since the IS compensates atleast 2 stops in low light for hand holding. But if its outdoor then u can easily handhold this and shoot some great photos in good lighting conditions. Also i would like to mention that being a L lens this is a little heavy because of its solid construction. Its also big compared to the other startup lenses. It takes 77mm filters and it can be used even on full frame cameras like 5D. hope you enjoy this lens as much as i am doing....more info
  • Canon EF 17-40mm f/4L USM Ultra Wide Angle Zoom
    I bought this lens after contemplating buying the new 16-35 2.8. I had the money to buy the more expensive lens but I didn't and here is why. I was told by an aquaintance who test for Canon that the 17-40 f 4.0 is over all sharper and has less distortion than the new 16-35 f 2.8 (as of Aug 15 2007). I have heard this from other photographers as well. Also although it isn't an f 2.8 as like the 16-35 it does have a bit more range and I have found the focusing is pretty fast regardless. I think it is the best $700 I ever spent on a piece of camera equipment....more info
  • Definitely worth it.
    I own a lot of L series lenses from Canon and love this lens. I used it for a year on my 40D and was pleased, not extatic. Upon upgrading to the 5Dm2 I became extatic. The quality is great on a crop factor but when you compare it to the full frame, you will notice the difference.

    I also own the 16-35 f/2.8 and if you can afford it, that is the better lens to go with it. The price does correspond to the quality (in my opinion).

    Overall, I think that anyone buying this lens will be very happy, full framers more so than crop factor types....more info
  • Great on full frame, average on crop bodies
    This is a good lens, but it's certainly not great. Along with all other L-series lenses, it's more durable, weather resistant, doesn't rotate the front element. It has a virtually silent focusing motor which is a pleasure to use. The lens is light, feels solid.

    But as far as quality is concerned, it's average. On a full-frame camera, such as the 1Ds or the 5D, the corners are much sharper than that of a 28-135, for example. But on a cropped-sensor camera such as the 40D or the XTi, you will not see almost any difference in quality between this and the 18-55mm kit lens. I've tried, you just can't. If you're trying to stay on a budget, look into the cheaper EF-S, Sigma or Tokina alternatives....more info
  • Great Lens, but not sure if Gray market version
    Hi,

    The Lens itself is really excellent. When I received it, I wasnt sure if it was a gray market or US made. I only wanted a US made lens, to avoid all the warrantly issues with the gray market. I returned the lens back to amazon, and got the exact same copy from BH.
    As termns of quality, its overall excellent. The built is perfect, size not too large, and picture quality is sharp. When photographing people, I wouldnt recommend shooting at 17mm, since it distorts quiet a lot I thought. Once you get around 24mm, its excellent. For outdoors, the lens is amazing. I use it on canon 30D, and the wide angle is perfect. Obviously, if shooting with a tripod, a lower F stop will give sharper results. F11 is awesome.
    I'm not really sure if amazon sells US or gray market versions, but since I couldnt find any info on the site, I decided to play it safe. I also got 70-200 F/4 and its definitely US version. The guy at BH told me, that US models have 3 serial Numbers listed in a row on the box, and Gray market versions only have two.
    Canon doesn't warranty Gray market lenses, but you'll just have to pay for it....more info
  • Canon EF 17-40 L-series lens
    An incredibly sharp lens. I have used Canon lenses for years, but this is the first time I,ve ever used one of the L-series lenses. I am completely sold on these lenses, and will never buy anything but the L-series from now on....more info
  • This lens completes XTi (or 30D).
    Although this lens is considered as ultra wide lens, for XTis and 30D's, this is really a 28-65mm lens (not "ultra" but regular wide). I purchased this for about $700 at Amazon to replace the kit lens 18-55mm the XTi came with. I am very pleased with the photos that I am taking. The focus is quick. The images are sharp, and the color is beautiful. I like the lens a lot. Because it's a F4 lens, I do need to use the flash. With 430EX flash I am getting pleasing shots in low light situations as well. I suppose a lower F stop might be better but I don't think Canon makes a lower F stop lens of comparable build. I did consider 28-70mm F2.8L (45-112mm on the XTi), but then it's no longer a "wide" angle lens. Compensating for the crop factor, getting a wide angle lens meant 17mm or less. So, this was really the only choice I had for an L quality build at this price range. Over all, I am very satisfied with the build quality and the results. The 40mm (64mm on the XTi) is a bit short, and I wish it were longer. However, giiven that this lens costs only (did I say "only?" lol) about $650, I have no complaints about the lens. Something's gotta give. It's weight is nicely substantial (not too heavy), and since I use my XTi with a battery grip all of the time, the combined weight balances well in my hands. To me, the battery grip and this lens are perfect companions to make the XTi's complete. I like this 17-40mm f/4L USM Wide Angle Zoom Lens for my XTi....more info
  • AMAZING
    I bought this product for my sons graduation. He absolutely loves it!! He had wanted it for a long time and he said it was worth waiting for. Thanks for the great service also....more info
  • Two Nations Tour
    "Great lense and very sturdy. I bought it for our to trip to Seattle, Victoria, and Vancuvar. It took great pictures. A bit pricy, but no regrets. Now I want to buy the telephoto lense."

  • Really, this lens is worth what you pay for it.
    This is one of Canon's best deals as far L's go. I use this on a full frame 1Ds for wide captures and on an XTi for use as a standard zoom. The F/4 aperture is something you'll just have to work with and the image quality is very good. The lens is incredibley tough. For a cheap price you're getting a lens that can withstand a drop from about 5 and half feet and still be good. I droped this lens on concrete - it landed on the front lens cap corner and then landed again on the rear lens cap corner. It still performs like a charm. You see.. this lens will last you an eternity. ...more info
  • I'm happy.
    I debated for quite a while between this lens and the 17-55 f/2.8 EF-S IS. I'm still drooling over that lens, but what it came down to in the end was my plan to upgrade to the 5D when, and if the Mark II is released. Of course, the other lens that could have made the decision even more difficult is the 16-35 f/2.8L, but it was way out of my price range.

    I'm happy with my choice. The lens is well built and sharp. If I have any complaints it would be CA. This lens does tend to show a bit of color fringing, but nothing and extra five seconds in raw processing can't fix. So I guess that point is moot.

    Overall, this is a good lens. Well worth the money. Especially at this price....more info
  • Walkaround for 40D
    I like many others who got their hands on a 40D considered the 28-135 for a walkaround lens. As good a lens as that is, I decided instead to opt for my first L lens - the 17-40. As soon as I had a chance to review my first photos I knew I had made the right decision. My 17-40 is incredibly sharp, the bokeh at f4 is excellent, and the colors are perfect. Obviously I lose a lot of range on the long end but gain quite a bit on the wide end. I have found it to be a good combination with the 430EX flash for inside photos (watch the white balance). Outside, it is my everyday choice for walking around, sometimes requiring me to move physically closer to subjects (that is a good thing). The 17-40 also means that my next "L" purchase will be the 70-200 f4, 70-200 f4 IS, or the near perfect 135. One of those, combined with the 17-40 and 50 1.4 will meet almost all of my needs. The 17-40 is a wonderful lens and well worth the investment, especially if you are an amateur lucky enough to have a 40D....more info
  • Good Lens however...
    I got myself a 30D and after hearing all reviews about the kit lens decided I should upgrade to an "L" series lens. I did a side by side comparison on a tripod of the 17-40mm L vs. the 18-55mm kit lens. I used different apertures and focal lengths. Overall, my opinion is that the 17-40 is better. However, it was not, in my opinion, a huge difference. At some settings, I really had to look hard to find some differences. Don't forget this is just a subjective test. Perhaps I was expecting more from a lens that cost me almost $900 CDN. For me, the jury is still out on whether it was worth the amount I paid. Ok, some say I got a "bad" lens but I've heard others that have had similar results with the lens. I shouldn't have to and I don't have the money to shop around for a "good lens"....more info
  • canon EF 71-40mm f/4l lense
    THIS IS ONE GREAT LENS ,VERY SHARP WITH GOOD CONTRAST ,FUN TO USE AND GREAT RESULTS .I HIGHLY RECOMMEND IT . ...more info
  • Pleased but not amazed
    I'm sure this would give you a lot more performance on a better body (I have a XSi). It provides wide-angle- you can go into a room and capture wall to wall with not too big of a problem. 17-40mm is a good range to get landscapes and then the occasional portrait. Night shots are amazing with a tripod, I was stunned.

    The bad:
    Not great with portraits if you want a lot of bokeh. I had fun zooming out and taking self portraits with friends or objects in the background but when you want to really focus on the subject, you won't get extreme bokeh.

    Overall, you are paying ~40% less than any other L lense and let's face it, that L is worth a lot. I use this mainly but I am upgrading to the 24-135mm 3.5-5.6, I miss the upper range (used to have a 70-300). I would say this lense would rock for HDR- something geared toward landscape shots, but portraits, macro, not that useful....more info
  • Great value
    This lens is really sharp and feels really solid. Weather sealing is a nice touch too. I would have gotten the 16-35 f2.8 if i could afford it, but i don't regret getting this one a bit. Besides, if you want a lens for landscapes, you won't need something at f2.8 anyway. Save the money and get a fast prime for low light stuff. ...more info
  • Love it
    Got this to go with my 5d. Great lens, sharp as a tack for a wide angle zoom. Very quiet motor and fast focus for a wide zoom. Love it as a beach walk around lens....more info
  • you dont really get this lens..this is only for full frame dslr
    this lens is good
    very sharp
    and very good
    but not enough zoom range
    and it is only for full frame machines
    especially for film slr s
    because in a crop factor dslr it is not enough and it is not wide enough..canon 10-22 is more good than this
    for a full frame there is some vignettint issues and corner softness..so this is only good for film slr
    if you have rebel series or 20d 30 d go with canon 10-22
    if you have film slr buy this lens...more info
  • Not too impressed...
    This lens takes pictures as though the lens has a cataract. I know it's not a prime, but I would think for an L series, it would take better pictures. I have a prime 20mm & 50mm F/1.4 which takes razor sharp pics in comparison.

    I just read another review which states Canon sometimes ships lemons which need adjustments. I will be contacting Canon and give an update on the outcome.

    On a side note... This lens feels very well made, is light, short, and ultra fast. I just wish is was sharp.

  • Great start to the L series addiction!
    This is my first L lens, and as others have said in these reviews, it certainly causes an addiction to the highest quality glass Canon has to deliver. Everything said about quality in the image and focus speeds is correct, as this lens in amazing!

    My only fault with this lens is that a 17-40mm range is just not good enough to be a full-time walkabout lens, but I knew this before getting it. My current use for it is as a lens on my second camera that hangs from my shoulder as I shoot events, and an excellent lens it is for that purpose! I suppose, paired with the 70-200/f4L it would work great, but you see there this is more of a combo lens than a solo workhorse, at least in my opinion. Fortunately, carrying two cameras is something a lot of photographers already do, and using this lens as part of a combo team just makes you even stronger with your capabilities as a photographer....more info
  • Wow
    Okay, nobody is going to rate this as a good review, because I am not going to elaborate.

    Basically, I love this lens. Love, love love love love. I am a fan of having a zillion lenses, and if you are too, you should probably have this to add to your collection. I have 7 lenses for my old 35mm Olympus, and wanted to outfit my 30D with all those fun things. So, I did. This is my favorite of all my lenses I own. I haven't found a single problem with it yet.

    The only hassle is finding 77mm filters. A lot of places don't go that big....more info
  • mediocre lens for L-glass
    Perhaps it's always true of wide angle lenses (i'm still new to this arena), but this lens seems a little dark, a little sloppy, just not quite good enough. With the exception of a few panoramic lake-front or ocean beach shots, i've seldom been pleased with the results, despite pairing it with my full-frame Canon EOS 5D. In contrast, i love the photos from my not-L-glass Canon 100m macro or my similarly "inexpensive" Canon 70-200L f/4.0 (which has amazing color rendition and excellent bokeh). It could all be my fault, but i think this lens just isn't sharp enough (despite its L-glass designation), and the color isn't rich enough. Sure, there's always post-production, but i hope Canon comes out with a better wide angle lens in this price range. ...more info
  • Worth every penny!
    Great lens for the beginner as well as for the seasoned pro. Razor sharp images....more info
  • overrated

    This is my first L lens. I own a Canon 50 f1/8 and also a 100 f2, both
    fixed length lenses. My rating is not so much to say that this is a bad
    lens because it's not. For 600+ dollars it is just extremely average. I
    would recommend looking at aftermarket lenses before buying this one.
    You could save a lot of money. ...more info
  • newest most used glass!
    this lightweight little wonder is always on my camera, i really hardly ever take it off...i do however, find the hood a bit...much, that being said the feel and operation is obviously that of an 'L' lense ...more info
  • Nice glass, well made.
    If you are going to purchase this lens then you have read the reviews. It is all that people say. F/4 is a little slow but it is a short lens so low light shots hand held are possible with a steady hand. Great build, nice weight, great lens....more info
