The SMCP-A 400mm f/5.6 telephoto lens is power zoom and auto focus. It can be manually focused and zoomed on all Pentax bayonet camera bodies. With 6.2 degree viewing angle, it provides all program exposure modes. Power zooms to what? 400mm-400mm?! ;-) And autofocus!!!! The google search put the FA* version as the description for this lens too....geez. Anyone want to tell me how to use these features? I seem stuck at 400mm and have only MF!!! It can't be 'zoomed' on my MZ-S or my MZ-5n! ****************************************************** Brad W. Dobo, HBA (Eds.) Email: [EMAIL PROTECTED] ICQ#: 16566668
