Well, I believe both werenŽt designed for the FED2... the FED-Industars and KMZ-Industars were meant for the LeicaII-Copies like a FED1 or a Zorkii1, not the later FEDs.Originally Posted by Ole
With grinding it down youŽll probably losen the tab.On some (but not all) of the Industar lenses the focusing tab hits the camera front just before infinity focus. I'm tempted to grind them down a bit...
Ole, may I suggest something else? Your lens is a KMZ-Industar22, whats the production year?
I have a I22 from the early 1970s here - a friend bought that for his Bessa R, got stuck with a problem and gave it to me as a gift. The problem? A nerd cut of the Tab which now allows mounting it to later FEDs but leaving it without a mechanical stop from unscrewing it.
What about exchanging the two parts - you get the "FEDed" ring, I get a functional one and we both can use it with our cameras... It seems to weight less that 20g which would allow me to send mine via "Europabrief" - a letter. Everything else would be prohibitive in terms of shipping costs.
