These are the filters only- the system also requires a filter holder and adapter ring (sold separately)

A neat little camera

This is a new-production version of the classic Zenit Jupiter-3

Leica Winder M4-2 format_620 These are the filters only-The Leica Winder M4 2 attaches to compatible Leica M cameras and makes them loud. Serial 15868, so this one has a maximum of 3fps advance. In excellent cosmetic condition overall, with a bit of a waxy texture to the leatherette, very minor surface wear from light use and handling. Includes box. Works, but these have a reputation for being a bit rough on cameras, so use at your own risk.
