My first post on digital images captured with the Canon nFD 50mm 1:1.8 was titled Five Frames with a Canon nFD 50mm 1:1.8, Tagging On RawTherapee 5.4 as it was more about the RAW image processor rather than the lens itself. Let's hope that this post will give more justice to the lens itself.
The Canon FD 50mm 1:1.8, first introduced in 1971, was the smallest, lightest, and cheapest of Canon's 50mm primes. The first version sports chrome filter threads and a silver breech-lock ring. The model was replaced in 1983 by a version with black plastic filter threads. The 'New FD' range, where the breech lock mount was replaced with an internal locking device, was introduced in 1978, and this series is commonly recognized as the 'nFD' lenses.
The update saw the minimum aperture of the lens lowered from ƒ/16 to ƒ/22, a reduction in the number of aperture blades from 6 to 5, and with more plastic components incorporated, a decrease in weight from 255g to 170g. Mounting the lens with the new lock mechanism is much easier, and can be done using only one hand.
Except for the 50mm 1:1.8, all other lenses in the 'nFD' series were given the S.S.C. (Super Spectra Coating) treatment. Image quality, as can be seen from these images, may not auger much if you are thinking about this lens as the top prime of your collection.
