Overhauling Canon FD 50mm f1.8
« on: May 10, 2020, 21:05:35 »
Happy Sunday everyone!

This is me turning a non-working junk into a nice lens :)

the problem I had was the aperture was not working at all. Everything inside got scrambled and the blades were full of oil.

Having experience with Nikon, I can tell that Canon FD aperture coupling is design disaster. I am not surprise they scraped FD mount completely in late 80s.

Cheers,
Zang

Picture of lens still looks like "junk"?    …...not a nice working lens?
How did to adjust for infinity?     …..by marking the helicoid and try to assemble exactly like it was?

I put together everything as it was, but it missed the infinity (tested on film SLR). My guess is the infinity was wrong previously. I nailed the infinity by slightly adjusting the focus ring position as shown in the picture.

...

It was dirty oily and stiff to the degree that no one would think trying it would be fun ;) ... beside I had no way to use FD :)

I do not have Z. I have just bought NEX6 for $35 and when waiting for the Yashica mount Matt sent me from Vermont, I found an FD adapter for $3 :)

btw... someone gave me the lens with a body for free. The lens was not functioning. The camera is fully mechanical and has non-working 8s shutter speed. I used them for decoration hanging over my desk. Now, only the body is left as the decoration :)

I read that Stanley Kubrick got a Canon 50/1.4 modified for use on movie camera......so must have been good.
The same with a Nikkor 180/2.8.

Yeah, the adapter is Fotga brand that probably costs $10 new on Amazon. I burned more on gas to pick it up than for the actual adapter. The result is pretty impressive. This one was wide open at 1.8.

According to the information in the video:
https://petapixel.com/2015/04/01/a-look-at-the-camera-lenses-used-by-stanley-kubrick-over-his-career/

...the Canon lens Kubrick used was a FD 35/1.4     …..maybe if you can get it for a few $ you could test this lens also. It probably performs well wide open.....

Thanks for sharing the interesting video! FD lenses are pretty rare here now, though.

I can't find a picture of a FD 35/1.4   ….so I wonder if it was a 35/1.4 or maybe a 50/1.4.

Yeah, 50/1.4 could be the one :)
