I have noticed that different cameras appear to have different refresh rates (frames per second) with their LCD screens. I used an oly c-770 the other day and the screen had maybe 2-5 frames per second, it made it almost impossible to use. The FZ series (FZ10 at least) seems to have a very high frame rate and almost no delay. I have never read anything about this sort of thing in reviews but it seems very important when it comes to taking photos. Has anyone ever heard of this in reviews or know if its called something else?
