I'm meaning that when you depress the shutter halfway, the camera will do the focus. If you keep the shutter depressed halfway, it will stay locked focus to that distance and you can move the camera to the framing you'd like. It's a bit difficult with fine focusing though. It'd be nice if it'd show you the focus in the viewfinder like on an SLR, but I'm sure I'll get used to it. OTOH, I got your e-mails Craig. Thank you. I'm still looking through them.
I am still curious about the non-exposures I was dealing with though.
