Life after death

Canon FD 50mm f/1.4 S.S.C. (Built in 1977)
This lens was actually alive and well when I bought it overhauled, but the large amount of lubricant was blocking the diaphragm blades.
I had to remove the entire lens top, diaphragm and control plate with its spring.
The blades and mechanical parts were washed with isopropyl alcohol, then I reassembled the pieces and checked the good functioning of this superlative lens!
You can evaluate the quality of this lens yourself in the images you will find in this Gallery: https://pbase.com/bracciodiferro/wettshirt

I dared to clean a Nikon 610 sensor, a special magnifying glass with LEDs fitting the camera lens opening helped plus a nylon brush, sensor size wipes and special cleaning liquid. And indeed learning first how to do it. I am a big admirer of your photographic work, congratulations.

Good job boss. I recently acquired the Canon 50mm f/0.95. I only shoot it at 0.95 so I'm not sure if it has this problem. :-) V

Good description. From the last image, I see why you needed to clean the diaphragm blades!

Your a far braver man than I....I don't imagine that's a inexpensive lens, one little mistake could have been costly. It sure did take great images after you finished with it though.

What an interesting gallery, and very impressive that you were able to repair the lens yourself. V.

Pretty interesting. Now I know how they remove the ring holding the front element of the lens, they have a tool for it. BV
