AF 2.8/80 - Df

[herman k]

Hi
Is it safe to use the AF Nikkor 2.8 /80mm on my Df ?   ( was intended for the F3AF )
The manual says 'not competible' .
Does that mean AF is not working - which is no problem - or will it possibly damage the camera.

Has anyone tried this?

It doesn't hurt to try ....

The pin-outs are different on the AF 80 thus it's unlikely AF works. Metering might run into similar issues however one has to try to tell what happens.

The earliest Nikon DSLRs had significant problems with the AF 80 though, as the pin-out configuration lead to a short-circuit of the camera battery I think the modern Nikons are capable of coping with this?

(I changed the CPU and contact block of my AF 80/2.8 many years ago to a modern layout, so cannot test the original lens)

I didn't encounter any problems in the DSRL's from D3/D700 and later with the 80/2.8.  Also the D200 and Fuji S5 pro work with the lens. This also applies for the big brother: the AF 200mm f/3.5

Did you get proper metering as well? I assume AF didn't work.

[John Geerts]

Metering works just like an ordinary AIS lens.  AF does not work,  AF will only (limited) work with an adapted teleconvertor:  TC-16a

Great!

I was a bit afraid of damaging ( ) something.

Birna; to disable the CPU circuit is an easy job to do?  or ( John?) not necessary as you are using it with the D3 ??  No battery drain?

I never noticed any battery drain on the D3 and later camera's with all the F3AF lenses I use and have used. I always left the CPU circuit in it's original state (as received after purchase) Standard the AF will work on the F3AF and the F4 camera.
