I brought the Zorki Jupiter 3 on a three-week trip to Paris and London along with my M10 and liked the character of this lens a lot. Just for reference, this is a 50mm f/1.5 lens with a variable, non-stepped, aperture ring. It’s compact, and light and when I got it a few years ago in Tokyo it was about $80, but like everything else, I think they go for a bit more these days.
The gallery below is a mix of black and white and color images. They’ve all been edited in Lightroom. If you’d like, let me know and I can provide an unaltered DNG.
