The Pony Premo No. 3 is one of Rochester Optical Co.'s famous wooden drop bed folding view cameras. It was made for the popular 4×5" film plate format. It has an exciting feature, a diaphragm that can be stopped down to f/128. Such a small aperture might cause diffraction problems when actually used. Therefore the camera's aperture scale reaches a bigger aperture than f/8 on its other end. Five different shutter speeds from 1 sec. to 1/100 sec. plus T and B mode, and a Rapid Rectilinear lens of Kodak let it be a mighty instrument for the ambitious amateur of its time. But it has just a reflecting type viewfinder. Maybe the camera's Victor shutter is an advanced version of Bausch & Lomb's famous Unicum shutter, with one piston for speed control, and the other to connect the air tube of a shutter release bulb. The camera model was continued when Kodak took over Rochester Optical.
