The CANON 17-40 WIDE-ANGLE ZOOM LENS is one of Canon's best all time selling lenses. Does that mean it's a good choice for you? This post will give you some ideas if it's worth the money for you to consider.
The 17-40mm f4 is the most affordable of Canon's wide angle zoom lenses. The 16-35mm f2.8 and the 20-35mm f2.8 are both faster, but they're more expensive.
This Canon lens has the full-time manual focus. It has the USM (UltraSonic Motor)for fast and quiet focusing. It is actually considered an Ultra-wide lens when used with a full-frame DSLR.
The maximum aperture is f4 throughout the zoom range.It has the common 77mm size for filters as well as a holder in the rear of the lens for filters. Just like other Canon "L" lenses it has the weather-resistant features built into the lens as well.
LANDSCAPES PHOTOGRAPHY. When your shooting the great outdoors, you often want to fit more of the scene into your composition. The 17-40 is considered a super-wide angle lens and gives you the perfect range of a super wide to moderately wide angle of view.
SMALL INTERIORS. The 17mm setting will give you the ability to shoot wide shots in cramped interior areas. Real estate photographers must used them to be able to show as much of a room as possible in each photo. The Canon 17-40 is also great for shooting a large group of people indoors where you don't have much room to use.
ARCHITECTURE. Similar to shooting landscapes, you need to show as much as you can of a large subject. Tall buildings, bridges, any large subject needs a lens to have a wide view to fit large subjects into your photograph's composition.
STRONG PERSPECTIVES. Super wide angle lenses the the 17-40 give you strong perspectives for creative photography. Objects closer to the camera appear disproportionately bigger than objects further away.
Watch this video shot while using the 17-40 lens on a full frame camera. You'll get a good feel on the angle of view at its widest setting of 17mm and see that compared to the view from a more typical 24mm wide angle lens.
For me, no. Can you use the Canon EF 17-40mm lens for portraits? Yes, but really only for large group portraits or for strong perspective portraits where you want size distortion of your subject on purpose. Portraits are more flattering if a more distant, flatter view of your subject is used. Longer mid-length telephoto lenses are more typically thought of as good for doing portrait photography.
The 17-40 is more typically used for shooting landscapes, seascapes. nighttime photos of the skies and photographing interiors where the spaces are tight.
Super wide-angle lenses are really not the best choice for macro photography because your close working distance can be challenging. With that said, the 17-40 lens focuses as close as 11 inches and gives you a 1:4 macro ratio.
Generally speaking, most macro photographers prefer longer lenses. Normal focal length macro lenses, and even more so with telephoto macro lenses, give you farther working distances and flatter perspectives for shooting close-up photos.
If you're like me you like to save money. I wanted to try out an alternative and report back to the readers of this site.
After a bit of research, the ongoing favorite as an alternative to the Canon 17-40mm lens is the Tamron 17-35 f/2.8-4.0. I purchased the lens below in 2014.
There are alternative wide-angle lenses for you if you're not a Canon loyalist. At a much lower cost than the Canon lens, the Tamron is an alternative lens to use on your Canon DSLR.
I purchased this one and have been quite happy with it, accept for it's focusing noise when shooting video with my 70D. You can read reviews by quite a few photographers who have purchased it on Amazon below.
When I don't use Amazon, I buy from a leading online camera retailer, Adorama, for many of my purchases.
Have a blast shooting with your Canon!
