The Sigma 70mm F2.8 EX DG Macro is a large aperture medium macro lens designed for use on full-frame and APS-C format digital SLRs. Three SLD (Special Low Dispersion) glass elements provide optimum color correction and sharpness throughout the entire zoom range and Super Multi-layer coating reduces flare & ghosting. A floating internal focus system enables a minimum shooting distance of 7.4 inches, and maximum reproduction ratio is a 'true' macro 1:1. It has a reputation for being one of the sharpest lenses on the market, but autofocus is slow.

Sharp and quirky
I gave this lens a "5," but there are a few caveats if you are thinking of buying it. But first the good stuff: it is sharp. It is the sharpest lens I own, just a little more than the 135 STF. The reputation this lens has for corner to corner sharpness is well deserved (I have an APC sensor but I have no reason to doubt the reviews done with full frame sensors). The autofocus is extremely accurate (but see notes below). Even at f/2.8 and near 1:1 magnification, it nails the focus. Manual ...

Sigma 70mm F2.8 EX DG Macro
Five Stars for this beauty from Sigma. I was not looking to buy this lens but was offered it for $250 (Retail $499). Man, what a sharp lens. Sharp even at 2.8 from corner to corner. Only a little fall off, but nothing major. At F/3.5 to 11, it shines. I don't do much macro, but I have tried it with this lens and still, it shines. I use it more for portraits. Bokeh is great. Not as creamy as my 85mm 1.8, but close enough and the 70mm translates to 105mm on my D80. Anyway, if you were ...
Sigma 70mm f2.8 macro
I've had this lens for a while now, using on the D200/D300, now sold, now using it on my D700 and the F6. I have found this lens to give great results, corner to corner, the sweetspot is about f8. It is quite a light lens but feels solid. Contrast is good with a good bokeh. If its being used on a DX body Nikon it equates to a 105mm
