If you have even wondered about purchasing this lens, now is the time to pull the trigger.This is a great L quality lens, and the deeply discounted price makes it a no-brainer. You can look at MTF curves, clarity tests, but at the end of the day, it is a Canon L series lens and if it is good enough for Canon to give it that designation, it's good enough for me to add it to my collection.It's easy to get caught up with the scorecard game, and I have been guilty of spending too much time on DXO looking at scores myself. At the end of the day, the proof is in the picture, and I have yet to be disappointed with my purchase. Great photographers take great photos, and have been doing so since before this lens was designed, the point? This lens isn't going to be the ... MoreIf you have even wondered about purchasing this lens, now is the time to pull the trigger.This is a great L quality lens, and the deeply discounted price makes it a no-brainer.

This lens isn't going to be the rate-limiting factor in many photos, so unless you are going to blow a picture up to larger than your big screen TV and look at it from 6 away, chances are you'll be just fine.It's true that the technology with their RF lenses is superior, it a byproduct of the physics (optics), but that comes at a price. Do I plan on purchasing the RF 15-35 2.8L IS USM? You betcha! Will I still have a use for the 17-40 4L USM, you betcha. Great glass is great glass!This lens works on my DSLR's and really well on the EOS RP! It's well built like all the Canon L series lenses, great, albeit not weather-proof like some of the tanks in this series.At it's current price, it is the cheapest L series lens available, cheaper than the 70-200 f/4 USM, which is another great, non-IS lens delivering great images. Even if you plan on making the transition to the mirrorless R line up, these lenses perform amazingly well, with an incredible IQ resulting in fast autofocus.

As an independent filmmaker, my camera equipment is not only by baby and best friend, but my life support. Saving up for my Canon 7D and then purchasing lenses has been, by far, one of the most rewarding and exciting experiences of my life. Talking to the experts behind the desks and then talking to the pros behind the cameras, this experience was as thrilling as interviewing movie stars in an epic film or tour guides for a grand adventure I was about to embark on. After buying multiple lenses, from primes to telephoto; the Canon EF 17-40 mm lens was the best purchase Id ever made. Instead of needing a very large and safely padded camera bag for multiple prime lenses, the 17-40 mm is lighter and far more easily stored despite the gentle circumference difference from ... MoreAs an independent filmmaker, my camera equipment is not only by baby and best friend, but my life support.

After buying multiple lenses, from primes to telephoto; the Canon EF 17-40 mm lens was the best purchase Id ever made. Instead of needing a very large and safely padded camera bag for multiple prime lenses, the 17-40 mm is lighter and far more easily stored despite the gentle circumference difference from the base to the top in physical appearance. The lens is very clear and useful due to its wide range of focus, for photos and videos. I can just as easily shoot a close-up and a medium frame based on the feeling I am going for with a simple rack focus. Good care of the lens is simple, too. With a wide face of glass, lens caps are to be kept on during storage and travel. The glass responds best to anti-static cloth, and each knob adds to the delicate but simple infrastructure of the lens. Not much can stain the body and anything on there can be easily removed by being picked off or rubbed off with a dry towel. Air cans are best for reach the nook and crannies, also to minimize the possibility of damage to the lens, itself. Like most lenses, liquids are best kept away from it, along with sand and other dusty material. The last time I travelled to China, I contemplated bringing several lenses, but in the end, I packed my 17-40 mm and a telephoto lens. As it turned out, I used my 17-40 mm the most. From beautiful landscape to detailed ornaments, this lens kept my creative eye busy and captured every angle my heart desired. Perhaps its the confidence of the red band or knowing that Canon was in my hands, whatever the case, this lens renewed my love and need to shoot, as I hope it would change your life, too. If you dont have this lens, youre missing out. I know filmmakers often prefer prime lenses, but for travel, convenience, and quality, I highly recommend the Canon 17-40 mm lens.

Update: since Canon has released an excellent 16-35mm f/4 L IS lens it is impossible to recommend this to anyone. Designed a decade ago, it is probably the best value for money ultra wideangle for Canon full frame dSLRs, and an excellent all round lens for APS-C format cameras. The colours are captured rich and vibrant and the images are contrasty. This is also a great lens to capture lovely 14-bladed sunstars, which helps a lot with landscape photography. Interior shots are also an easy task with one of those. Finally, the weather sealing helps with shooting in adverse weather conditions.

If you want a great full-frame lens for landscapes buy the 16-35mm f4L IS. It's fantastically sharp and detailed and offers image stabilisation and weather sealing. It's also nearly twice the price of the 17-40mm f4L on the used market. The 17-40mm f4L is the most affordable L-series lens that covers the general-purpose range for crop-sensor/APS-C bodies, and will be the first step into the world of L-series lens for many Canon owners. Its main competitor is the 17-55mm f2.8 IS which is a stop brighter AND has image stabilisation, but lacks weather sealing and the cachet of the red ring denoting the L-series status. Weather-sealing is very nice but so is a 2.8 aperture coupled with IS. Both lenses hold their value on the secondhand market and both offer a ... MoreIf you want a great full-frame lens for landscapes buy the 16-35mm f4L IS.

Its main competitor is the 17-55mm f2.8 IS which is a stop brighter AND has image stabilisation, but lacks weather sealing and the cachet of the red ring denoting the L-series status. Weather-sealing is very nice but so is a 2.8 aperture coupled with IS. Both lenses hold their value on the secondhand market and both offer a significant step up from the 18-55mm kit lens. The one significant benefit of the 17-40mm f4L is it won't become obsolete if you upgrade to a full-frame body as it uses the EF mount (the 17-55mm f2.8 IS has an EF-S mount so can only be used with crop-sensor bodies). The story is different for full-frame users. Here the 17-40mm f4L presents a much wider view, offering extreme to moderate wide-angles and making it ideal for landscapes and architecture. It does have its limits though and full-frame users are more likely to invest in costlier and superior lenses such as the 16-35mm f4L IS. The 16-35mm f4L IS is significantly sharper and, importantly, offers image stabilisation as well as weather sealing - this will be the ultimate Canon lens for many landscape fans. Ultimately, those upgrading from a kit lens such as the 18-55mm EF-S, or those moving up to full-frame bodies will not be disappointed by the 17-40mm f4L. Why only three stars then? If I was to score this on value then I'd give it between four and five stars. Build quality is typically excellent, earning a full five stars. But, in absolute terms, it's NOT one of Canon's sharpest when used wide open. Landscape photographers will frequently prefer to use a tripod and apertures between f5.6 and f11 to maximise sharpness, but unless you always carry a tripod there will always be those times when you have little choice but to use it wide open to maintain an acceptable shutter speed. Image stabilisation would help to a degree but it wouldn't alter the fact the 17-40mm f4L is not as sharp as other designs at its maximum aperture. In my opinion a lens should be primarily judged on its optical quality above all else, and it's to this end that I give it between 3 and four stars. If you're on a budget you can't go far wrong with the 17-40mm f4L aslong as you play to its strengths. And, as with all L-series lenses, buy a decent secondhand one and you'll recoup your investment when you decide to upgrade.
This is my first L lens to pair with my nifty 50 and I must say I'm so glad I got it. I originally wanted the 24-105 however I am so glad I got the 17-40 for the simple fact that on a Full Frame sensor 17mm is so amazing to capture a different perspective. It doesn't seem that much from 17-24 but the perception and field of view is simply stunning. It's great for those small tight spaces where you want to capture a scene and even at 40mm lifestyle candid portraits are not to bad. Now at F4 you don't get that creamy bokeh that you would from say a 2.8 or 1.4 ect however it's still pleasing if your subject is far away from anything in the background. The lens is very sharp and even at 40mm F4 you can still focus pretty close and is nice and sharp. There is def some ... MoreThis is my first L lens to pair with my nifty 50 and I must say I'm so glad I got it.

The focusing is super fast and locks on nicely as well. I would recommend this lens to anyone looking for a reasonably prices L lens who likes landscapes or just walking around and wants to capture the moment you might be in.
About 16 years ago I had purchased the Canon EF 17-40mm f/4L USM Lens with my Canon DSLR at the time. It was the cropped frame so the lens was good but was not to its full potential. I ended up getting other brands but the Canon L was still the best performer. The lens and dslr were sold. I moved up to the 5D series of cameras and they served me well. I used the standard Canon L lens provided with my 5D -- EF 24-105mm f/4L IS USM. But I was still missing some coverage on the Wide Side of photography. I purchased my 2nd Canon EF 17-40mm and I cant tell you how happy I am with this lens. I made sure that the firmware software on the 5D camera is up to date, and put this lens on and off shooting. This item is a good carry around lens for me. I have taken some wonderful ... MoreAbout 16 years ago I had purchased the Canon EF 17-40mm f/4L USM Lens with my Canon DSLR at the time.

I hope this lens keeps in production;.
The EF 17-40mm is a pretty old lens that has gotten pretty mixed reviews over the years. But I was interested to try it, becuase both the 17mm and the 40mm extremes of the focal length range could be very useful for two very different purposes: Architecture and Events. No other wide angle zoom that I know of goes up to 40mm, which is a very desirable focal length for small group photos at events. I was skeptical it would be viable, but the rental was not that expensive, so I gave it a try. After using it for three days, I was hooked!I could have purchased the lens I rented, but there was a significant difference between the price of that lens versus used copies available elsewhere.

Classic Canon L-Series lens. I purchased this with a sigma MC-11 adaptor for my Sony a7Rii. I was cautiously optimistic given the lens's age and its DxOMark pixel resolution score (16-17MP).I'm using the lens for landscape photography with some noticeable diffraction above f/11. The f/4 aperture makes the lens much lighter and its age makes it much more affordable than contemporary wide-angle zooms (especially for a mirrorless platform).Given its price and weight, I'm more than happy with its performance. The landscapes I shoot are for prints. The lens may be holding my sensor back a bit, but if the image is correctly composed with the proper settings, any sharpness can be correctly dialed in in post. Where the a7Rii and Riii sensor can be punishing on some ... MoreClassic Canon L-Series lens. I purchased this with a sigma MC-11 adaptor for my Sony a7Rii.

Where the a7Rii and Riii sensor can be punishing on some lower-level lenses, I haven't necessarily found that to be the case here. Although if I upgrade to an a7Riv, I'll likely purchase a new primary, while keeping this as a secondary.I was expecting to utilize focus-peaking in conjunction with a proper depth-of-field in my compositions. However, with the MC-11 adaptor, phase autofocus has been quick and efficient outside of low-light settings (which this lens isn't built for). You'll lose eye-AF as well as tracking, but that's not a problem for me as I only utilize those features in portraiture. Contrast AF is useless, but I generally find that to be the case on most lens platforms.Highly recommend this lens to anyone on a budget, or for a piece of gear that you don't want to be afraid of getting banged up etc.
I wanted a wide angle zoom but I could not afford one of the more expensive Canon wide angle L lenses. The 17-40 f4 offers great value for money.The copy I purchased from Camarthen Cameras was a very good example. It is in excellent condition and works perfectly. It cost me £189 pounds and I am very pleased with it. I have a Canon EOS R and I use the Canon EF-RF adapter. The lens works perfectly with the adapter. The photos I have taken have been very sharp and the colours natural and lovely.The help and advice I received from the friendly staff at Camarthen Cameras was very good. I have purchased equipment from them before and will use them in the future.
"L" lenses are not magic, so if you are expecting extraordinary image quality from this lens then you will be disappointed. On APS-C, the image quality of this lens is not significantly better than the modern kit lens in my opinion. However, this lens is built like a brick outhouse. The weather sealing and the build quality are my reasons for buying this lens, and I am not disappointed. The materials and feel are exactly what you would expect from the L series lenses. If you know what you're buying, and are okay with the price, then you will not be disappointed. If you are buying this solely because of the red ring, then I would definitely not recommend it, as there are many better options out there.

Canon EF 17-40mm f/4L USM Lens
Wide-angle zoom is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 27.2-64mm equivalent focal length range. Constant f/4 maximum aperture maintains consistent illumination throughout the zoom range. One Super Ultra-Low Dispersion glass element noticeably reduces color fringing and chromatic aberrations for high clarity and color fidelity. Three aspherical elements minimize spherical aberrations and distortions for improved sharpness and accurate rendering. Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions. A ring-type Ultrasonic Motor (USM), along with an internal focusing system, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override. Rounded seven-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques. As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions. In addition to the front 77mm filter ring, this lens also has a rear filter holder for up to three cut gel filters.

Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions. A ring-type Ultrasonic Motor (USM), along with an internal focusing system, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override. Rounded seven-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques. As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions. In addition to the front 77mm filter ring, this lens also has a rear filter holder for up to three cut gel filters.
