Jupiter 8M in M39... frankenlens?

I think you're right.

Another opinion: personally, I don't call f/2 "fast". It's certainly faster than f/4.5, but to me anything wider than f/2 is "fast". Relative and subjective, I guess.
 
It is (probably) a Kiev-mount J-8 optical block in an Industar 26 mount. Advantage of clicks-tops (if you like them). Disadvantage is that it may or may not be shimmed correctly, so anyone's guess if it will focus properly on an LTM body!
 
that's what I thought. It looks nice, but I don't think it would work properly. Besides, I had never seen a J-8 with copper blades; tha samples I know all have black blades.
 
I have seen several of these on ebay lately, in I26 or I61 mounts. I guess someone has a bunch of old Kiev lenses to get rid of. I would be pleasantly surprised if they have been shimmed correctly.

Cheers,
Dez
 
[FONT=arial, sans-serif]Dear xxxxx,

Thank you for your interest in our products.
This Jupiter-8m has no click-stop. Aperture ring turns without stopping.

When I sent the lens for sale, check it only to infinity.
Now I specifically at your request checked the lens at a distance of 1 meter.
All right of Compliance label 1 meter on the focus ring.

Thank you.
Oleg

[FONT=arial, sans-serif]Dear grandseller,

hi. thanks for listing this lens. Normally, Jupiter-8m was not made for M39
mount, only the Jupiter-8. So my question is: a. Does your 8m have
click-stop b. have you tested the focusing, ie. 1m = 1m ?

thanks

There are more on that page from the same kind: have a look at the black ones. Btw I don't think they have click stops, since the optical block stems from the Ju8
