I've decided that rather than carefully annotate all of my tests and trials, which wouldn't begin to convince anybody anyway, I'll just come out with it and say what I think. But you've got to promise me you'll read this next bit and remember it as you go along, please: I'm not the arbiter. I don't get the final say. I'm just one photographer...one more, out of many. And I haven't bought, and am not going to buy, any of these cameras, so anything I say is not brand partisanship on my part, or self-congratulatory pride of ownership, or anxiety that I might have made the wrong choice, or insecurity that somebody else might own something better than mine, or fear that having a "less than the best" camera might reflect on my bad photography, or any of the other motives that fuel all the passionate nattering.
