Specification:- The Canon EF 24-70mm f/2.8L USM Lens is a very sharp lens - few zoom lenses reach this level of sharpness. The 24-70 L is sharp in the centre at f/2.8 at all focal lengths and performs very well in the corners. Some corner softness is visible at the wide end of the focal length range and more softness is apparent in the 50-70mm corners. As usual, stopping down (selecting a narrower aperture) to f/5.6 makes a big difference in the longer focal length corners. The wide open 24mm corners are most-affected by vignetting. Vignetting is very well controlled, but apparent in the corners at f/2.8 at 24mm on a full frame body. Vignetting improves as the focal length increases and the aperture is narrowed. At comparable apertures, the 24-70 L shows less vignetting than the also-excellent Canon EF 24-105mm f/4L IS USM Lens - a typically-expected result when comparing a fast lens to a slower lens. Like most 24-xx zoom lenses, the 24-70 L shows some barrel distortion on the wide end. More specifically, a bulge in the middle of the frame. Barrel distortion disappears around 35mm. A very slight pincushion distortion begins at 50mm and becomes moderate by 70mm. Colour, contrast and saturation are excellent. CA (Chromatic Aberration) is very well controlled - especially for a zoom lens. The wide 8-blade aperture produces a nice quality background blur and a nice amount of it. Prime lenses (fixed focal length lenses) are often compared favorably to the 24-70 L. They are generally less expensive, smaller, lighter, faster (aperture) and very sharp. My personal preference is for zoom lenses for my photography applications in this focal length range. To me personally, the ability to change framing instantly far outweighs the slight image quality advantages fixed focal length lenses offer over the 24-70 L. Im often asked - can images shot with a consumer zoom lens be post-processed to result in images similar to 24-70 L images? The answer is: you can adjust contrast and saturation, but you cannot add missing detail. And, colour can be very difficult to match later. So, using a better lens will usually result in better post-processed images. Most primes and L lenses are noticeably better than consumer zooms. Image quality is not the only pro-grade feature of the Canon EF 24-70mm f/2.8L USM Lens. Excellent AF is part of the equation. A Ring USM (Ultrasonic Motor) AF system delivers quiet, fast and accurate autofocus. The 24-70 Ls f/2.8 aperture enables the enhanced-sensitivity of many Canon EOS DSLR bodys AF points. As usual for a Ring USM AF system, FTM (Full-Time Manual) focusing is enabled. The 24-70 L does not extend with focus and the 77mm filter ring does not rotate.

This short focus distance provides a very nice MM (Maximum Magnification). While not close to a 1:1 macro lens, the 24-70 L can take nice flower shots, product pictures ... Although it is not compatible with Canons extenders, extension tubes will extend the 24-70 Ls macro capabilities. Canons extension tube offering are the FE 12mm extension tube and EF 25mm extension tube. The Canon 500D is a close-up lens that attaches to the filter threads - it also allows closer focusing distances - sorry, I dont have the spec for this one. Sporting a red Canon L Series Lens ring, the 24-70 Ls build quality is also, as expected, top of the line. Though not light, the 24-70 feels solid, is comfortable to handle and has a logical layout. The focus and zoom rings are nicely-sized and operate smoothly. Weather sealing (when attached to a weather sealed body) completes the physical quality package.

Of course, the 17-55 gains its advantage by not delivering a full frame 35mm image circle (being an EF-S lens) and by having a lesser build quality. And the 24-105 allows only 1/2 as much light through its body at wide open aperture (f/4 vs. f/2.8). The 24-70 Ls 77mm filter diameter makes sharing filters (such as a circular polarizer filter) with most of Canons other L-Series zoom lenses easy (and more affordable of course). Canon Normal Zoom Lenses Size Comparison - Retracted Pictured above from left to right are the Canon EF 28-135mm f/3.5-5.6 IS USM Lens, Canon EF 17-40mm f/4L USM Lens, Canon EF 24-105mm f/4L IS USM Lens and Canon EF 24-70mm f/2.8L USM Lens. Canon Normal Zoom Lenses Size Comparison - Extended Pictured fully extended above from left to right are the Canon EF 28-135mm f/3.5-5.6 IS USM Lens, Canon EF 17-40mm f/4L USM Lens, Canon EF 24-105mm f/4L IS USM Lens and Canon EF 24-70mm f/2.8L USM Lens. Of note is that the 24-70mm L reverse extends - it becomes longest at 24mm as shown above. Most lenses including the 24-105 L become fully extended at their longest focal length setting. Canon Normal Zoom Lenses Size Comparison - Hoods On Pictured above from left to right with their respective and included lens hoods in place are the Canon EF 17-40mm f/4L USM Lens, Canon EF 24-105mm f/4L IS USM Lens and Canon EF 24-70mm f/2.8L USM Lens. Of note with the lens hoods is that the 24-105 Ls hood extends with the lens while the much larger 24-70 L hood stays in one place. Most lenses including the 24-105 L become fully extended at their longest focal length setting and their lens hoods travel along with this extension, but the 24-70mm L reverse extends - it becomes longest at 24mm as shown above. Because the 24-70 L lens hood is in a fixed position (it does not extend/retract), the objective lens retracts deeper into the hood as the focal length is increased. In other words, the 24-70 L lens hood extends much farther from the objective element of the lens at 70mm than at 24mm. The 24-70 L is using an appropriate-for-the-selected-focal-length lens hood at all focal lengths while the 24-105 and most other lenses are using a made-for-24mm hood at all focal lengths (like most zoom lenses). 24-70mm falls right in the middle of the general purpose lens focal length range. The Canon EF 24-105mm f/4L IS USM Lens review has a helpful focal length comparison that includes this range. Though not ultra-wide on a 1.6x FOVCF body, 24mm is noticeably wider than the 28mm minimum focal length provided by lenses such as the discontinued Canon 28-70 f/2.8L Lens and some of Canons consumer zooms such as the Canon EF 28-135mm IS USM Lens (a good value lens).
