And an angle finder does almost the same job (not
quite, I admit). But
how many 35mm film cameras did? An Exacta, a couple of Nikons, and not
many others.
Off the top of my head, and ignoring camras like that older Prakticas
that had a built0in waist level find and a clip-on pentaprism option that
fitted into the hood of the waist level finder...
Nikon F, F2, etc; Canon F1, etc; Exakta Varex. Exa 1, Exakta RTL1000;
Paktica VCL (and later models in that series). Miranda Sensorex, etc.
Pnetax LX (I think); Start; at least one Zeise COnsarex (not the Bullseye
one); Leica Visoflex attachment for rangefinder cameras; etc.
And therre's even the 16mm film Narciss.
