Speed Magny Backs Turn Nikon F Cameras into Instant or Large Format Cameras

During the 1960s to the 1980s, photographers who wanted to check their lighting or churn out images for very quick reportage had a secret weapon: the Speed Magny. This interesting contraption allowed them to produce Polaroid prints with their Nikon F, F2, or F3 cameras. While the entire setup looks rather bulky and awkward, it was still marketed as the "Instant" Nikon.
