I have owned many different cameras, many different brands starting with Retina IIIC in 1966. Just picked up a working Topcon Auto 100, of all the manuals I have read the manual for the Topcon is one of the worse, no the worse manual I have ever had to decipher. The camera it'self is fussy, not as bad as the Retina, but making heads or tails of how how to set the shutter speed to manual, took an hour.
. Of course so did I in 1975
I went to senior prom in a powder blue tux wearing blue platform shoes
