Don't pick on me either. I have illustrated the difference between my 1Ds3 and 5D2 in the area of pushing shadows. It is a very minor difference, but one that some will be interested in. People are reacting as if I, or perhaps others, are putting this forward as a reason not to buy the camera. It is a very minor difference that you will probably notice if you go from 1Ds3 to 5D2. It's not a question of looking for problems, it's a question of noticing a difference in the camera in normal use, establishing the issue, and demonstrating it. This helps people make informed decisions. If people reading those posts set too much store by a minor limitation, let them. That doesn't mean that I shouldn't share my experiences here. There are plenty of people here who are capable of taking in the information and acknowledging the miniscule scale of the problem. Let people react hysterically, and ridicule them if you like but don't think you will be able to stifle perfectly reasonable conversation amongst those of us who do feel we benefit from these discussions and demonstrations.
I take far too many pictures, and FM is a good way of stemming the flow.
