Mount Adapter
Minolta MD/M42
For using Minolta cameras (XG, XD and others) with M42 lenses (Praktica, Zenit).
Metric scale M42 keeps its meanings due to compensation of the flange bases
difference. Therefore focusing can be to infinity.
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 red marks of the adapter
and lens collar together.
- Turn the adapter clockwise
till the fixative click.
- Set M42 lens.
Removing:
To remove the adapter you should unpress fixative pin and turn the adapter
anticlockwise.
