#1 I just bought the D70 and can't seem to set it to where the 5 focus circles can be highlighted when using the thumb control as on my N80. It lights up where it focuses, but I don't have the control. What do I need to do?

#2 Is there a way to save (on the camera) a zoomed image? When reviewing you can zoom in to a particular part of the image - but is there a way to keep that image? Or does that have to be done with the software?

Thanks in advance!
