Old Sigma 105mm vs New Sigma 105mm

[dEARlEADER]

Am I in for any major loss of quality if I get the old (non DG) 105mm f2.8?

I was reading something about reflective coatings being more important for digital sensors??

ps-
I realize I can't autofocus with either version with the D60 and this is not important to me...

Be more specific. There are 2 current 105mm Macros in the Sigma lineup, both are DG so that didn't narrow it down. One has APO coatings. Both perform remarkably well.

Load of marketing fuzz. The coatings affect flare and contrast and the problem is identical regardless if you're using film or digital.

The one I'm thinking of picking up is used.... the manual description is

Sigma 105mm EX F2.8 Macro

It doesn't mention the "DG" which I'm assuming is the redesign for digital?

I just want to make sure there is no major difference in quality... if anyones knows that would be great...
