Manufactured in 1958 for the T and M series cameras, the PC-12 is a parallax correcting preview finder with viewing fields for lenses of four different focal lengths, 16mm, 25mm, 50mm and 75mm. Although less versatile than the octameter, it was introduced for current and potential Bolex owners who desired a viewfinder that changed focal lengths with faster speed. The Bakelite screw-in eye cup is missing.
