Adapter Contax-Yashica/M42
For using Yashica/Contax cameras (FR,
FX-3, 109MP, S2B and others) with M42 lenses (Praktica, Zenit). Delivery set:
the adapter ring, and the wrench for setting the adapter. M42 lenses are completely
interchangeable with Contax/Yashica optics, as they have the same flange base.
You should remember that the pusher
with the fixed ring doesn’t work, so diaphragm control of the lens is set manually.
This adapter can work with lenses having both only automatic diaphragm (A) and
selector A/M (automatic/manual diaphragm). It is possible to use Macro rings
and other accessories.
Settings:
- Put little groove of the adapter and the
red mark of lens collar together.
- Set the wrench to both rectangular grooves
- Turn the adapter clockwise till the fixative
click by the wrench.
Removing:
- Set the wrench to both rectangular grooves
- Press stop button on the camera, turn the
adapter anticlockwise by the wrench.
