Way back in the 1960s, there seemed to be some sort of special trade agreement between the UK and the USSR, and a variety of Russian photo goods was available, including Leica screw lens in 28, 35, 85 and 135 mm focal lengths. I had all of these plus a Leica IIIa body - the lenses were excellent, I would not say Leica standard, but highly usable and very good value. I have always wanted to know if these lenses are still made, as the FSU is still making Leica-thread cameras, it would be logical if they made lenses as well, but I haven't seen anything but 50 (-ish) mm lenses bundled with cameras available for years.

My take on Russian cameras was and still is - it doesn't matter if they are "built like tanks", the shutters will break soon, they will be uneconomic to fix.
