Hello new list readers, Bob, your understanding is incorrect, both of these lenses EF 17-35 2.8L and EF 16-35 2.8L were designed for use on full frame 35mm format cameras. I've owned and used both of these lenses and while not perfect this lens fills a pretty broad range of uses on my 1.3X and 1X bodies. When I bought my first EF 17-35 2.8L there were no practical, usable professional quality digital bodies available for the Canon EF mount. When I bought my first EF 16-35 2.8L the first new professional 4MP EOS 1D bodies had been announced at $7,000 but you couldn't get them at any price unless you were a Sports Illustrated or ESPN, they were very, VERY scarce and film was the main media of the 35mm format SLR bodies. Fast forward 4 years to 2005 when any Tom, Dick or Jane can buy a fully featured consumer DSLR with 6MP sensor for $800 and now you have an understanding that is simply incorrect. Wilber, I'm a professional photographer shooting primarily architecture and professional motorsports and I have been shooting digitally for about 3 years now. I use the EF 16-35 2.8L and EF 15 2.8 FF Fisheye lenses everyday on EOS 1DS bodies for architecture and have no problems with distortion at all. ALL of the lines in my finished images are ruler straight when using either lens. Of course there are several digital corrections involved but what do I care? When a shot can sometimes take hours to setup and light and an other 10-15 minutes to get the camera positioned and the image framed correctly what's an other 15 minutes in post capture doing distortion, perspective and vignette correction for an image? This is what I get paid to know how to do to produce corrected images. At normal distances these lenses have some minor distortion that are not noticeable to the average person without obvious straight lines running all the way through them as do ALL optical lenses. For an image where you want to take advantage of the perspective distortion that ALL very wide angle lenses have when focusing very close what do you expect, straight lines? This is simply the nature of ALL very wide angle lenses and most armatures don't realize this and then say the lens has very bad distortions, this is NOT a lens fault.
