The J-12 3.5cm F2.8 is an inexpensive wide-angle lens available in Contax/Kiev mount and in LTM. It is a coated copy of the Pre-War Zeiss Biogon. The J-12 cannot be used on the Contax IIa and Contax IIIa. It will fit on all Kiev's, COntax II, Contax III, and Nikon S-Mount cameras.
I've custom-shimmed one J-12 for a Nikon, but it was probably off to begin with. The 1960 chrome J-12 that I use now was good-to-go on the Nikon.
The lens has good contrast, color rendition, and is "sharp Enough". Watch out for flare and reflections.
All of these photo's were taken Wide-Open on the Nikon S2 at the Udvar Hazy Air and Space Museum. Kodacolor 400 film.
The Space-Shuttle Enterprise. Used for unpowered glide tests of the Airframe.
You can see the blue-reflection at the bottom of the image, from the bright window above.
