Why does a manual 50mm lens show f/0 on a Nikon D7000, and why can’t I change aperture from the camera?

I’m using a Nikon 50mm f/1.2 manual-focus lens on a Nikon D7000. When it’s mounted, the camera shows unusual aperture values like f/0 to f/7 instead of the lens’s actual f/1.2 to f/16 range. I also can’t change aperture with the camera’s command dial and have to use the aperture ring on the lens. Is this normal for this lens/body combination, and is there a way to make the aperture display correctly?

In your menu go to the setup menu (spanner). Near the bottom is non-cpu lens menu option. Here you can set up to 9 lenses manually. This will get the aperture display to show correctly.
For example i have a 50mm 1.4 with which i use an adapter. This lens i have set to number 1. That way when i change f number the camera knows what the setting is.

Yes — this is normal for a non-CPU manual lens. That 50mm f/1.2 has no electronic contacts, so the D7000 can’t control the aperture or automatically know which f-stop the lens is set to.
What to do:
- Set the aperture on the lens’s aperture ring.
- Use the camera’s Non-CPU lens data menu to enter the lens focal length and maximum aperture. This lets the camera display aperture information more correctly and meter more usefully.
- The camera still will not physically change the aperture for you, because the lens is fully manual.
So nothing is necessarily wrong with the lens. The odd f-number display happens because the body doesn’t have electronic communication with it until you configure the non-CPU lens settings, and even then aperture control remains manual.
