DPReview is definitely the predominant reviewing site, and the do a very admirably and un-enviable job of trying to do very objective, rational reviews in the face of bias and rabid fans. And they do a pretty good job. I, personally, think they place too much emphasis on a few areas because it makes measuring easier (noise performance, for one), but that’s the name of the game.
All of this is lead-up is to say “Hey, DPReview has their massive 31 page review of Panasonic’s GH1 up!”
The GH1, of course, is sitting in an interesting spot, with a sensor half the size of the 5D Mark II’s, but with an interface and lens designed from the ground up to handle video better. And so far, it sounds like it wins the video battle. But, hey, read that long review for yourself and make your own decisions. Then come back to us and order yours with free ground shipping to the lower 48..
