<p>Hello, I would like to use my 200mm Canon FD prime on my Lumix GH-1 and am wondering how this will ultimately affect, if it will affect, DPI for any prints I wanted to make. Do I still have an effective 12.1MP's? I'm primarily a film photographer and am wondering if I need to upgrade to a FF sensor in order to best utilize my old FD lens arsenal. Probably won't be looking to enlarge much past 8x12".. Thanks everyone, Mark</p>
