Ken Rockwell has posted side by side reviews of the old and new 60mm lenses on his site here:

and here:

This mostly confirms what I believe and have heard from others namely that the AFS is sharper in the corners and is fast and reliable, better than the 105mm VR.
But he made some interesting points that I was suprised about:
1) The AFS version has slightly more distortion and falloff than the old version
2) The AFS version doesn't focus reliably on the D3 or D300
3) The AFS has even less working distance than the old version. This is no doubt due to the IF.
Bjørn Rørslett had a better review of this lens. http://www.naturfotograf.com/index2.html He stated that distortion was negligable. Light falloff isn't an issue for me as with macro highlighting the subject is a good thing and no one shoots macro at f2.8 anyway. Distortion isn't a big deal underwater either. For you crazies out there the smaller front element will also allow you to use the 3/4T diopters with this lens in the same way you can with the 105mm VR, in case you want to photograph the lint inside your port. ![]()
Less working distance may be a problem for those that would use this lens as a true macro lens, possibly making it impossible, its so close already. But I use this as a fish portrait lens and the 105mm for true macro so again this isn't an issue
AF performance IS the issue as getting even faster results on fluttering fish is important.
Appearently Bjørn Rørslett tested this on the D300 and D3 but didn't mention any AF irregularity. I own the AFS version and have had very snappy AF results on my D70. Much faster IMHO than with the older AF lens. But I don't have and haven't tried this on a D300 or D3. Can anyone confirm Ken's findings on a D3/D300?
