Hello. First question. When in, say, aperture priority, do I have to have the lense switched over to 'M', instead of 'A'? And another, is there a thread or sticky somewhere on how to use manual modes? I am trying to learn, but get stuck. If I put it on P mode, and move the command dial, someimes nothign changes at all, all though my book sais "moving the dial right will increase f/# (lower aperture) and left will....." it might be the other way around, but either way, it often won't change anything at all. I just really want to use the camera in manual modes, no more auto. I want to be more involved with each picture. Let me also say that I've had my camera for like a week, and have been out 3 times to take photos, always using the preset modes (landscape, auto, macro...you get it.) Thanks! I am also going tomorrow morning to hike at a state park here, but unfortunetly will be using auto, for I doubt anyone will respond before I go. Well thanks!
