Does anyone know if the 7" Aero Ektar will infinity focus when mounted on a Graflex RB Super D? I understand that the 7" is a little shorter than what the Super D was designed for, not to mention the size of the optic and mirror clearance issues. Anyone know for sure by chance? I'm really interested in a Super D that's available to me, and I like the idea of mounting either an 8" Pentac or a 7" Aero Ektar for portrait work. Suggestions?
