Shooting Rolleicord VB 50% of the time.
I have just picked up a Minolta Autocord (export), Ricoh Diacord G, and a Yashica-Mat ... I have yet to run any film through them, so I cannot say exactly how they compare. From all my research the IQ of these are in the order that I have listed them. I have even read that some think the Minolta is as good as the Rolleiflex's.
dxqcanada: results of your testing of these 3 fine cameras would be of interest.
