>>2921605 The lens design for SLRs and rangefinders is different - accounting for different flange distance - between the lens and the film.
While there are adaptors, such a lens won't focus to infinity and is only good for macro or closeup stuff.
The kiev/contax mount jupiter-9 is a pretty rare beast compared to its m42 and m39 brothers, so your best option, unless you intend to just use it in a contax/kiev, is to sell it and buy an m42 version.
>>2921629Yes, b/w film keeps very well. Bracket a few testshots on first roll to learn how to best expose them.
There is a problem, however - all the ORWO rolls from your photo are SL casettes - a rapid loading system made in the east to rival kodak's amateur-friendly 126 format.
They are meant for approx (iirc) 12 or 16 square 24x24mm shots on each roll and only fit SL-compatible cameras. Which is a small array of low-end viewfinder point&shoots, mostly. The list's on camerapedia. They won't work in normal 35mm film cameras.
