I just got the new Nikon Z7 camera.  I tested several lenses.  All worked well except my AF Micro Nikkor 60 mm which does not focus.  It worked well with my D850.  But with the Z7, in my settings it is frozen to "Manual focus" even if the lens is set to A instead of M.  I cannot change in the i" menu from MF to AF-S, it os frozen to MF.

What could be the problem ?

What version is the lens?

The adapter needs lenses with a focus motor in the lens for the AF to work. The two versions from before 2008 depend on the camera having a focus motor.

What Peter said. If it's a 'D' lens like the one I have you'll only have manual focus with the Z7 and the FTZ adaptor. For whatever it's worth, I never use my lens in AF anyway. It's much easier to focus manually with this lens. At least in my experience.

I don't have that specific lens but, when I do macro work,
I only use manual focus except for focus stacking.

Thanks all of you for your useful replies.

Yes. I have the AF MICRO NIKKOR 60 mmm 1:2.8 D lens and it may not have an internal focus motor.  Since it worked with the D850 it means that this lens relied on the body focus motor to operate the autofocus, is that correct ?

Anyway, you are all right in saying that doing macro is better using manual focus than autofocus and I started lately to do this to better control which area should be in focus.

When using the Nikkor 24-70mm a version I bought may be more than 10 years ago, and a Nikkor 14-24 mm f2.8 (bought a year ago) the autofocus works well with the Z7 and would this mean that theselenses havean internal focus motor? (probably yes since they are quite heavy to carry)...

Lenses with the motor built-in are designated AF-i, AF-S or AF-P. The suffix indicates what type of motor it is.

 

The mass of your lenses are because of the amount of glass needed for fast zooms as the gearbox for the screw-drive is about equally heavy as a motor.

 

You are correct in your assumption that the 14-24 and the 24-70 are both AF-S lenses.

if you have any D lens lenses they will be manually focus only. no motor on inside of body to autofocus. now if nikon was smart and thought about making tons more money would come out with lens mount adapter that would make all d lenses autofocus.

Not quite. There are a few AF-S D lenses that have both the aperture ring and the built-in focus motor. The 17-35, 28-70 and AF-S 80-200 are all D lenses with AF-S. So are the early versions of the AF-S Tele primes.
