The Nikon F3 meter pattern uses the same 13mm circle as the FM and FE series models. Nikon uses a centerweighted pattern and the weighting is 85/15 from center to edge in the F3 compared to the F/F2/FM/FE 60/40 weighting. (Yeah, I know the spec says it is 80/20, but measurements with a point light source on my F3 established quite conclusively that it was actually 85/15 weighting. I did the testing because I was curious that my FM and FE cameras gave different readings when pointed to the same scene with the same lens...)

The M6 meter pattern is a limited area pattern, not a centerweighted pattern... It reads the central white spot on the shutter curtain that's about 12mm diameter, so has a more well-defined cutoff than the Nikon F3.

In truth, and for all practical purposes, they respond so similarly there's hardly any difference between them in use.
