The Takumars, of course, and many many Soviet and DDR-made lenses are still in my posession and use - a fabulous titanic Helios-40 85/1.5, a small Makro-Flectogon 35/3.5, Orestor 100/2.8 and 135/3.5, a strange but amazing Industar-61 L/Z, and others. I also cured my 50/1.4 Takumar from yellowing by intense UV irradiation, so I can shoot slides with it now without any cast
