Took to the street (again!) yesterday with the GXR + Helios 58mm and Industar 50mm. Both great Russian lenses. Some here and also on the blog for those interested...
I may be joining you! I just got home this afternoon armed with a new purchase. Got a GXR body, the M-Mount and electronic viewfinder (all together as a very clean, well in fact as new used from RG Lewis in London). The M6 has gone but I retained the CZ 21mm f2.8 Biogon lens to use on it. This will replace my GRD3 which has a scratched lens. Looking forward to getting some use out of it. Heading into town for a night shoot.
From the look of your excellent shots here, it does street very well indeed
