what it is ?

Basically it is a nikon AF emulator chip which can be attached to all types nikon mount adapters (see my pictures below)

what it does ?   

I)  prompt for focus confirmation --  no more guestimation for focus.

You still need to manually focus your lens; Precision focus will be acknowledged by a sound and light signal. On the screen you will also find highlighted spots that got into focus area. Junior level digital cameras will provide an acknowledging beep.

II) The chip has the programming option, that is, you can change AF emulator chip’s aperture and focal length settings without removing it from the camera. In addition, the chip has calibration function that makes focus confirmation more accurate.  You can program the following parameters:

work for my Nikon ?

it works perfectly with all digital and film* Nikon AF cameras, except the following 3 models:

F4, F60, and F90X

and for F5 and D1X/H models, the programming will not work...

you can also attach the chip to a manual nikon/nikkor lens

(below is the chip attached to a nikkor-H 50f/2 lens)

note: some lens has parts get in the way where the chip should go, in that case, 'surgery' is needed to clean the way for attaching the chip

------ FYI ..  a quote from one of the customers...

"Some information for your customers. For NIKON lenses, the centre of the 4th pin, must be exactly in line with the centre of the top most screw on the mount of the lens. For non-Nikon lenses, and some Nikon accessory rings, the screw pattern positions of the mount differ to those on NIKN lenses, so people will need to measure from the locking slot at the left of the lens when its mount is viewed from the rear."

Please... be careful when attaching the chip... do not glue it permanently without checking it first..

by 'checking'...   note, you're forbidden to check it with the chip direct (without attaching to the adapter first) on a nikon camera, see picture below:

most of the cases, this will cause a short circuit, and damage the chip....
