Jolos TM Mount Adapter
Sony Alpha (DSLR-A100 )/Minolta AF/M42
For using auto focus Sony Alpha/Minolta cameras 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.
Bear
in mind that aperture pusher is not pushed. 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.
Note:
Working
with M42 lenses acknowledgement of the focusing with green light is not made.
The aperture is not set. Expo-modes:
- P (program) – identical to
Av mode;
- Tv (flash priority) – doesn’t
work;
- Av (diaphragm priority) –
works as usual;
- M (manual) – aperture and
flash are changed. Inaccuracy of exposure defining is indicated by expo-correction.
