Opinion: A wonderful camera!
Now I'm using this camera since about six weeks and encountered only very little problems (see "Problems" section). All in all I am very impressed by the performance of the camera. It gives me the feeling of the handling of an analog SLR like F90x (speed, variety of settings etc.) combined with the advantages of digital photography. This was exactly the camera I was looking for. It is great not only for "normal" photography but also for longtime exposure, available light and I am very impressed by the IR performance!
Problems: Very rarely but I encountered it was colour moiré which was hard to eliminate in postprocessing and normal moiré that was easy to get rid of. The eye cup gets lost easily if you don't pay attention.
