I tend to use a collapsible Industar-22 more for balance of compactness and IQ, in lower light I use a Jupiter-3 more. I also have a nice chrome Jupiter-8 and a black Jupiter-8-1 (worse build quality, but better color rendition), also there's a nice zebra Industar-61 (non-LD), a rare version with 9 aperture blades — rather nice, but not much sharper than J-3 at f4 and further. Also I have a collapsible Industar-50 and a collapsible FED 50mm f3.5 — the FED is the most compact one, but has the worst IQ of these 3 collapsibles. Speaking about J-12, I have a black LZOS LTM one, I've blackened it's apeture blades myself with a sharpie-like marker — now it flares much less, but the best J-12, I guess —*it's an Arsenal-made one with Contax-Kiev mount. Older Jupiters have perfect matte black diafragms, newer ones are just plain unpainted metal — thus more flare. But newer ones have a bit more modern coatings, thus better color rendition, like the black Jupiter-8-1. But I never had any problems with color film with my ZOMZ J-3 and KOMZ I-22.
