“An interesting innovation in the Tele-Rolleiflex is a removable glass
plate within the camera, in front of the film. With such a long focal
length lens, it’s understandable that the maker of the camera should want
to keep the film plane as precise as possible.”
“You’ve got to inspect the glass each time you load. Beware of
thumb-prints, grease or dirt that sticks. These will cause greater harm to
the negative than if they were on the lens itself! However, we shot most of
our pictures with the glass in place and each picture we took came out
” We then took the Tele-Rolleiflex out on actual field tests. Besides
checking the lens, we were also interested in discovering how well the
glass plate kept the film flat – in terms of actual picture sharpness.”
“With the glass in place, overall sharpness at f/4 was very good with only
the slightest fall-off in definition at the corners and a tiny amount of
flare. Maximum sharpness was achieved at f/8 – and this was sharp indeed.
This sharpness held right down to f/22.”
“Curiously enough, when we removed the glass plate, the loss of sharpness
was almost too minute to notice. – H.K.”
