Some people seem to think that you have to be completely detached from something in order to be objective. As a corollary, this would imply that people are the greatest experts on things they have no experience with; basically, it's like saying that only your enemies can have a valid opinion on you, since your friends are biased. This, of course, is utter nonsense. Knowledge comes from familiarity. Of course Michael has a slight bias towards Canon. He has good experience with their stuff and it obviously proved itself, or he'd sell it. What's he expected to do - sell all his cameras and lenses? Regularly write a disclaimer saying "I hate all the equipment I use"? Bleh. People should read his review of the Kodak digital back, where he basically expected it to be crap, probably from the experience with their SLR camera, and ended up so impressed he actually bought one. I guess if Olympus manages to make a pro body as good as his Canon 1Ds, he'd praise it all over, but right now, I own E1 and like it, but if Olympus doesn't make something soon enough, I might regretfully buy into another, more expandable system. I'd do it reluctantly, though, because resolution and noise performance are really my only objections to E1, which is otherwise ideal for me.
BTW, did anybody notice that people on the Sony forum on dpreview actually praised Michael for the same article?
