Re: [Leica] 'Russian' Leica-fit lenses

St.

A couple of weeks ago, you commented on the jupiter 12
lenses.  Just after that, I purchased a Jupiter 8, black f2
50mm.  The lens seems to be quite sharp and smooth to
operate.

The one issue I run into after so many years with other
lenses is the diaphragm setting that rotates with the front
of the lens when I focus.

You noted in your discussion of the Jup. 12 that it has an
"awkward" diaphragm setting.   My question, (finally)  . . .
Do all Jupiter lenses rotate their aperture setting?

Thanks,
