I recently bought a MPP Mk VIII camera outfit with two Schneider lenses, an old 150mm Xenar & a 90mm Angulon f/6.8 (Not Super-Angulon). I have just bought a spare lens panel for it as I would like to add a more modern lens like a Schneider 180mm APO Symmar-S or similar. What I was wondering was, will I be able to close the camera up when I have finished using it the same as I can with the Xenar lens? Also, would someone suggest a good focusing loupe that is not too expensive? Thanks.
