The Industar-61 L/D 55mm f/2.8 (Russian: "Индустар-61 Л/Д 50/2.8") is a kit lens for FED rangefinder cameras. The  application of lanthanum glass made it possible to get rather high resolution while preserving a simple optical scheme and a 2.8 lens speed (44/30 lines/mm center/edges).

Besides the barrel, a blackened aperture with the greater number of blades (six vs. five) sets Industar-61 L/D apart from other SLR versions.

-strong OOF fringing

-ice cold colors

-blueish CAs sometimes also when stopped down

-rather low contrast

-bad flare control

-optimum performance F8-F11 (depending on quality spreading)

-under average sharpness, also stopped down to F8-F11

-low acutance

-bokeh is not my taste

-Alu build, very soft


Comments:

I don't get why this lens has such a good reputation. It's imho one of the worst 50mm lenses on the market.

I had several other USSR and GDR Tessar(-like) lenses and this was the worst of them. Industar 50-2 and Industar-22 are better for my taste, aswell as CZJ 50/2.8.

Many cheaper 50mm are better. Minolta MD 50/2 for example.
