I won't get into is the Nikon D700 or Sony A900 better than the 5DII - while some folks will change brands for most the investment in lenses makes that a decision not made easily. But is it better than the 5D? I have to say yes - it has better resolving power and equivalent ISO performance.


One thing that I don't see mentioned in all the strident comparisons is a huge but simple thing: Autofocus Microadjustment. If you haven't tried it on your own lenses, it alone is worth the upgrade whether you're talking 40D to 50D or 5D to 5dII. I hear people saying "I won't bother with that", but the people who actually take the time to calibrate their lenses to their camera seem to all find at least one or two of their lenses are markedly improved.
