Contax Yashica Lens to Nikon F mount adapter ring

With AF Confirm Chip for Nikon

With correction optic, focus infinity

 

Detail Information

For using Nikon cameras with Contax Yashica (C/Y) lenses. It is impossible to compensate flange bases difference without using an additional back lens. As a result, the picture quality becomes worse.

After adding optical element, focus infinity becomes possible. Please note that diffusion effect occurs when the aperture is larger than F/4.0, adjusting aperture to lower than F/4.0 is recommended.

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.
