Hi! You skipped a step in the lens evolution. First breachlock lenses were "manual" as you described. A new generation was issued shortly after (not sure when) which had a spring to turn the breechlock partway so the lens was now almost fully mounted. I still needed a short turn to secure it fully.
As far as I recall there are also an even older version of the FD lenses that has no spring apperture. So you have manual stop down the aperture when pressing the shutter.
Those are "FL" lenses! Technically a different lens mount, although the lenses can be mounted and used on FD cameras in stop-down mode, like you said. Before that, even, they had the Canonflex cameras and their "R" mount! It has the same physical dimensions but different internal pins and springs, so it won't work properly on newer cameras. But they brought that breech-lock along for the ride for quite a while! Thanks for watching! - Connor
Does somebody know if the very early chrome lenses have single or multi coatings? I have 35mm f2. It is quite a nice lens but it has a bit of yellow tint on it. Actually I don't even mind it since it works well with 500t film in daylight.😅😅😅
Some have single, some have multi! It's the same SC and SSC system, just not marked on the lens. The 35mm f2 should be multi-coated. Thanks for watching! - Connor
One more annoying thing i've found about FD lenses is, if you're using extension tube for macro. It's really easy to twist the extension tube ring when you're trying to get the right aperture.
If I had a dollar for every time someone couldn't get the rear cap off their breech mount FD lens I'd be wealthy. When I simply twisted the breech ring and the cap popped off they were amazed. They were rotating the cap, not the breech ring.
Sollte sich der silberne ring nicht durch Federvorspannung von selnst drehen und arretieren? Zumindest macht das noch der Zwischenring welcher ich für mein 100mm f4 Makro hab. In anderen Videos habe ich das auch schon mehrfach gesehen. Ich habe allerdings nur nFD objektive. Daher kann ich das leider nicht ausreichend verifizieren.
The silver ring should turn back on its own with spring tension, yes. That being said, many lenses today require a bit of assistance to lock in fully. The spring gets them about halfway and then the user twists it the rest of the way. Hope that helps! - Connor
I prefer the older FD lens mounting, I find the nFD to be overly complex, and more susceptible to jamming, use FD lenses daily and have tone for 35 years
Very good video showing the differences between FD mount lenses. I have a bunch of them. Thanks.
Glad you enjoyed it! Thanks for watching!

thank you so much for this video

@@Kamerastore - thank - "FL-lenses" I had forgot they had a different name.

That’s only happens when the person has absolutely no idea what they are doing.

I have the SSC & the nFD. The Nfd is sharper & has better color & contrast. The nFD is actually an impressive lens being from 1981
Some people like the build quality of the older leneses but on the other hand they're older leneses with all problems that come with age
