    This is a magnificent lens deserving of high praise. In general, I tend to shoot "available light" and towards wide angle, and EF 17-40 F4L is one perfect lens for someone like me. On an APS size sensor camera (mine is Rebel XT), it works approximately like a 28-70 mm zoom--a perfect walk-around lens, giving you decent wide angle and at the tele end, a pleasing perspective on faces you expect from a moderate telephoto. I spent two weeks with EF 17-40 on the coast shooting nature and street stuff in small towns. It performed perfectly. But I only realized what a real treasure I have when I began having second thoughts about it on the eve of a long overseas journey. I asked myself whether I would not have done better buying EF-S 17-85 F4-5.6 IS. After all, it gives you better reach - an equivalent of 28-135 mm zoom on a 35 mm camera. Would it not be a perfect lens on an overseas trip? A dilemma worhty of Hamlet. So I decided to order it from Amazon while I still had time to return EF 17-40. As soon as EF-S 17-85 came, I did some tests taking pictures of still life, flowers and a portrait at similar focal lengths and at full zoom. The results put 17-85 to shame. Color and light were flat and paled next to 17-40. But there was still the problem of reach. I took a portrait at full zoom of the same person (40 mm or 65 mm equivalent and 85 mm or 135 equivalent), cut out the critical focus area from both pix and equalized the two crops in terms of pixel numbers. Unprocessed, 17-85 produced a perfectly focused picture, the 17-40 crop was visibly softer, but in terms of tonality and richness of gradations, it was way ahead of its rival. Photoshop to the rescue! After I fiddled with sharpening and contrast in CS2, the focus softness in 17-40 was gone, and the result was a better all-around picture of the same portrait detail. In other words, if you wish to take a picture, say, of a building's detail or a monkey mug shot in a zoo--a situation calling for a telephoto of 135 mm that 17-85 is capable of--EF 17-40 F4 can do the job, in fact a better job in terms of textures and tonality--and focus, too, if you do a little post-processing in SC2. I am returning EF-S 17-85 and will stick with EF 17-40, taking it on my overseas trip. Unlike EF-S 17-85 F4-5.6, which is a feels like a decent consumer zoom, EF 17-40 F4L is built like a tank and has weather sealing. It should also come in handy if and when I decide to switch to a full-frame camera (EF-S lenses work only with the APS-size sensors).
