Interesting answers.


I won't repeat any of the previous dialogue, but I will mention a few things I notice. I too own a 1D MKII and a 50D (plus 3 other bodies). I do a lot of shooting where I pair up bodies and lenses for an event and then have pictures from many bodies to work with I'm compiling proofs for a client. Some days, this means I'm looking at8MP images from the 1D MKII and XT, whilealsoworking with 22MP images from my 5D MKII. There's too many variables to analyze, but sometimes one body just handles white balance, focus or some other variable better than the others.


My1D MKII never focuseswell with the 2X converter, butmy XTi willwork perfectlyin the same lighting. My 50D needs moresaturation in post processing than anyof my other bodies. My 1D MKIItakes sharpeningbetter in the RAW files than any of my other bodies...and the differences go on and on.


Ithink there are a lot of small variables with lenses and bodies than impact image quality. Anyone out there who hastwo copies of the same lenshas noticeddifferences...
