Helios 77M-4
Tried the ND8 on the Helios 77M-4 to take full advantage of its f/1.8 in full sun, and honestly, those AF confirmation chips are a godsend. It used to take me far longer to compose in live view; AF beep through the viewfinder is nothing short of miraculous.
Also tested it using the 12mm macro extension tube, though for my own use something like a 7mm would probably be more usable. Keep an eye out for the first test of the Helios 44M-4 coming soon to a blog near you!
