1. Put red marks of the adapter and lens collar together.
2. Turn the adapter clockwise till the fixative click.

To remove the adapter you should unpress fixative pin and turn the adapter anticlockwise.

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.
