@sakkasie April , Pentax SMC vintage Prime lenses render some wonderful colours ,, so I think part of the praise belongs to the beautiful 28mm SMC f3.5 prime lens
@phil_howcroft my Jupiter 8 lens is still sitting in the box that it came in. It was for my Zorki 4 but my Zorki is having "issues." It only likes to capture half a roll of film.
