The above seems to be a bit elusive to me. I'm looking for an adapter to allow M39(LTM) lenses to fit an F mount. Yes, I know they won't infinity focus-I need to do some high magnification work at work, and I'm looking at the old trick of using an enlarger lens on a set of bellows. I had a couple in FD mount, and at one time it seemed that they were ubiquitous in pretty much every lens mount. There again, in the dark old days this was a common way to do high magnification work. The F mount version seems elusive, though. I can find plenty of adapters to put F mount lenses on LTM cameras, but not the other way around. Can anyone point me to one, or perhaps have one lying around that you'd want to part with?
