Lens looks nice. But it has couple problems. First, auto focus is very stiff, so lens is not auto focusing. But it can be used in manual focus mode. Focus is still smooth, just too tight for auto focus. and second problem is aperture blades don't spring back. It seems that spring is damaged. But aperture can be adjusted manually, using aperture ring. On digital cameras that would cause FE error. Still lens can be used in M mode. So it still works in manual focus and manual aperture modes. My guess is that lens has been dropped and damaged. Even though I am not sure what might have caused these issues. Other then that, lens looks very nice. Glass is very clean. I don't see any scratches on the front. It has some scratches on the rear element (near the mount). I don't see any haze or fungus inside the glass. Please look at the pictures and video. Model AF Nikkor D 24mm f2. 8.
