Bojidar: Interesting approach and conclusion. I can see your reasons for leaving... But don't ever forget that it is the photographs that make the difference not the camera, not even really the lenses. If you want the latest and greatest USM, IS etc, go out and get it, but it really won't make you a better photographer. As I have said before, IS is fine for lazy photographer and special applications like shooting from a boat or something) but I use a tripod almost all the time and IS lenses would add nothing but cost to my outfit... I'm not saying that if Pentx came out with an IS lens I wouldn't buy one, but I certainly wouldn't change systems because of it. My suggestion would be to invest in film rather than the latest equipment....
