Jolos TM Mount Adapter
Nikon/M42
For using Nikon cameras with M42 lenses
(Praktica, Zenit). It is impossible to compensate flange bases difference without
using an additional back lens. As a result, the picture quality becomes worse.
So metric scale M42 doesn’t keep its meanings and focusing can’t be to infinity.
You should remember that extension
ring doesn’t work, diaphragm control 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. Approximate
focal lengths: 50mm-1,5m; 85mm-3,5m; 135mm-6m.
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 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.
