Judging by some of the EXIF info decoded by my copy of BreezeBrowser, I wouldn't like to design any type of system based on the "focused" distance. The focal length info appears much more believable. Whilst I just have one IS lens in my collection (the 28-135 USM IS), I can't remember when I last used the IS facility having largely gone over to using primes on my 10D. It was very useful on my EOS3 when shooting close-ups on Provia 100F of flowers high in the Alps under a heavy rain cloud. "Stupid" exposures of 1/4 sec got me acceptable results with my tripod safely locked in my car's boot!
