For using Nikon cameras with Tamron Adaptall 2 mount lenses.

Allows focus 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.

With AF chip (compatible with Dandelion) installed on a lens with an automatic AI-S aperture, the aperture will be controlled through the camera similar to autofocus lenses. This is one of Nikon's strongest points: you don't have to care about aperture when using an old manual lens.

There are only three film cameras that AF chip is not compatible with: F4, F60 and F90x. It works with all other models perfectly. 

Fixed aperture value at F/2.8.

Gives correction of focus confirmation dot. Using manual control (M) mode in manual focus (MF) function is recommended.

Settings:

Put red marks of the adapter and lens collar together.

Turn the adapter anticlockwise till the fixative click.

Set Tamron lens.

Removing:

To remove the adapter you should turn the adapter clockwise.

Note:

Working with Tamron lenses acknowledgement of the focusing is not made. The aperture is not set. Expo-modes:

Tv (flash priority) ? doesn?t work;

Av (diaphragm priority) ? works as usual;
