Hy,
i just bought a used nikkor 180 2.8 AF-ED
it is in good shape but mounted on my d70 i get constant focus errors : the lens focusses a little closer than it should, so my subject is out off focus (call it front focus)
I think my d70 is fine because other lenses work great.
How can i fix it? i located a little screw under the rubber focus ring, but i'm afraid to loose focus if i try to unscrew it...
thanks for your hemp! |

Auto-focus lenses are outside the scope of this forum and I suggest you visit one of the dedicated Nikon forums.
I cannot comment on Nikon kit. However it is a fault that is relatively easy to fix on Canon EF lenses. You need to follow the service/calibration procedure and have the correct test equipment. The repair is not a simple matter of repositioning a scale or loosening a few screws to realign infinity focus.
If you are determined to go down the DIY path, get hold of the repair/service manual that covers your type of lens. |
