Roger:
The 2.8F (K7 F) uses the Bay III created for the 2.8 B (K7
B) with the Biometar 2.8/80 in 1952 and then you have: BI= 28mm; BII=
34mm; BIII= 38mm.
Rolleiflex 2.8/80 lens TLR 6x6 cameras use shutters 0 size and
Rolleiflex and Rolleicord 3.5/75 lens (BI and BII) TLR 6x6 cameras use
shutters 00 size and then the shutters are different.
