I've skimmed though a lot of the posts, but have certainly not read them all. I went to a preview event today and got to shoot with one. First impression was great. The size, weight, handling all felt like a very compact, but solid camera. When you take the lens off, the body looks like it's ALL sensor. It's pretty amazing to see that they took what was the size of a digital back and fit it into the small body that they did. The AF seemed to be very accurate and the MF has a very nice long throw. The image kind of popped into focus, I'm not sure of the tracking capabilities. I didn't mess with any of the AF settings. The lenses were well sized and balanced. The HC adapter will allow use of the other lenses, but will add a lot of space between the mount and the lens. So it won't balance as well. It was pre-production firmware, etc. so we couldn't shoot to our own card.The EVF looked good, though not quite as good as the SL's. But I am very impressed so far and they are still working on adding a lot of functionality to the camera before release. If you are thinking about getting the camera, I'd highly encouraged you to find one of their demo days as they travel around the country with it. Hope this helps.
