Actually the second is the J-3! Sonnars always have a distinctive look to the out of focus areas, and also render colors warmer, in my experience.

There are a few Soviet lenses that looked like the Elmar 50/f3.5, with slightly different formulas and coatings. Internally they use a Tessar formula, so they aren't technically Elmar clones except the outward appearance. Those are the the Industar-10 (usually just labeled "FED 50/f3.5"), the Industar-22 made after 1947-ish, and the Industar-50 made after 1953. All lenses made after 1948 or so are coated. I'm under the impression that most fake Elmars are made from the later lenses lenses, unless you have a more carefully faked lens with a more Elmar-like aperture tab; those are usually from older Industar-10s which had a very similar tab.

Hi,

Weren't the taller ones (? Industar 50) a proper Contax Tessar clone? And the shorter ones the Elmar clone? I can't see them neglecting the Contax f/3.5 lens when they'd acquired it.

It would be interesting to see if they ever improved on them over the years, apart from the coating (and paint in the engraving). But until we get our hands on the factories drawings, we'll never know.
