Can I fine tune the manual focus confirmation on my Nikon?


I haven't seen this answered anywhere, but does something or some software exist to fine tune manual (!!) focus confirmation (the dot at the bottom left) to more accurately represent focus? If I have the triangle pointed rightward I know I'm in focus, rather than seeing just the "dot", and it's really putting me off. Would love to fix this, and I'm not afraid to use 3rd party software to get it done.



Answer



Based on discussion in the comments above, where it is experimentally verified that autofocus microadjust can move the automatically-found focus point back and forth from the point identified as in-focus for the manual focus confirmation — I think your theory is right and the adjustment is just applied as an offset to auto-focus. This is somewhat surprising, because as Kamen notes in another answer, it's just using the same autofocus sensors. Possibly a firmware update could change this, but I wouldn't hold my breath.


What I bet you can do, though, is send your camera and lenses to Nikon and ask Nikon to calibrate the manual focus confirmation for you — they can make adjustments that aren't available to end-users (possibly including physical shims, even).
