M42x1 ring lens adapter to Nikon photo camera 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 ring lens 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. Note: This ring lens adapter is only for long-focus lens (such as Rubinars, MTO-11CA and similar).

Settings:

1. Put red marks of the adapter and lens collar together;
2. Turn the adapter clockwise till the fixative click;
3. 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 set "0.0". Expo-modes:

1. P (program) - identical to Av mode;
2. Tv (flash priority) - doesn't work;
3. Av (diaphragm priority) - works as usual;
4. M (manual) - aperture and flash are changed. Inaccuracy of exposure defining is indicated by expo-correction.
