Is there any connection between any of these random, rambling posts and "Sigma macro's AF inaccuracies call for new optic!"?
Trying to regain some order, Sigma ART lenses can be tweaked.
However, Sigma's macro ART lens (70mm f2.8) is not available, and will not be available, in Nikon F-mount. This is due to technical reasons in making AF work properly (I was told this by Sigma Japan).
*THE* macro lens for Nikon-F is last year's ("F017") Tamron SP 90mm f2.8 AF VC lens.
