Rollei TLR optical glass pressure plate

[john_c.]

Some models of the Rollei TLR (e.g., 3.5F models 2 and 3) have internal

release pins to accept an optical glass pressure plate, supposedly to

ensure optimal film flatness. Does anyone use a TLR with one of these

plates? Are they useful, i.e., do they make a difference in picture

sharpness? And, are these plates available in the market today? Thanks.

John,

I used to own a Tele-Rollei that still had the glass plate with it. There is a place in the camera case to store the plate, that's where I

found the one for my camera. I tired it with and without, did not see

any major difference. The only problem was keeping the glass plate clean, I would always have problems with small particles of dust or lint from the paper backing from the film sticking to it....Bill

Dear John,

I think this glass plate will help when you use the camera in some photogrammetry work which need good flatness of the media to get corect dimension form it. so with some software you can bring out dimensions from the object you photographing.

Tariq,

 

I rather think that Rollie's glass pressure plate pre-dated photo-grammetic software, by a decade or three!
