Hi, can anyone help me? I have just got an MZ-60, but don't understand the details of the aperture ring. The following is a quote from a review "Usable Lenses: Pentax KAF2- and KAF-mount lenses. *When the aperture ring is set at other than the A position, shutter release
is locked." Does this mean that I can only use the camera in 'A' (auto?), and can I only put lenses on the body which have an 'A' on the ring?

I am new to this and any help would be greatly received.
