I have been reading two things that are kinda negative. First that the Af speed is slow, slower than a P&S or DSLR? Second that its has only 1/2000 shutter speed. Please someone educate me becuase this will be my first real camera. For a P&S user like myself and my wife who most of the time would be using the auto or the p mode, will all this effect us. Or is this only for advanced users, who change settings etc. I am interested to know because either way it will affect me, I want to learn photography on this cam.
