As good as it gets (S. Svarovsky, Phoenix, AZ, USA, 2008-12-27)

I can't say enough good things about this lens! The build, feel, sharpness are all top notch. The velvety EX finish screams quality even on the lens hood. I tell you my Nikon 18-200mm feels like cheap chinese knockout next to this one. I also compared it to Nikon 105mm VR and see no difference in performance, i.e. speed, bokeh, etc. If you are ready to fork out extra $200 for VR, then go for it. Otherwise buy this one -- you won't regret (btw, top choice digital has an excellent price on it). Despite what other people say, the focus on this puppy is very quiet and fast, fast, fast...unless you are focusing on low contrast subjects in a cave of course. The lens is good not only for macro, but is excellent for close up portrait and tele work. Great job Sigma!

The sharpest lens (G. Cheng, Mystic, CT, 2008-12-20)

The lens is sharp, not just as a macro lens, but as a general lens as well. I was concerned about the auto-focusing speed, but it turns out fast enough for me, at least on my Nikon D300 anyway. The lens has a helfty feel, which makes it easier to hold sturdy in hand for general usage. For macro work, the lens is on tripod of course. I especially like the tripod foot, much easier to rotate from lanscape to portrain position. The sharpest lens I have (compared with 50mm f/1.8 and 17-55mm f/2.8).

Very Sharp (Snap Shot, Richmond, VA, 2008-10-23)

I have nothing bad to say about this lens. It's very sharp, fast focusing and tough build. I also like the additional working distance over my 90mm macro lens.

Great macro lens (Julien Cap, France, europe, 2008-09-24)

On nikon mount: pretty good working distance (1:1 magnification at shortest distance, magnification decreases as distance increases), needs a tripod to start working with. The autofocus - though you don't really need it in macro - is silent but spends a lot of time searching in low light conditions (no miracles!). Really sharp.

Great great product (Davide Manca, Milano, ITALY, 2008-09-04)

Great product with excellent quality and crisp framing. The image quality is very high and possibly better than the SIGMA brother that works at 180mm.
Macro photography gets a real improvement through this lens especially when insects are concerned. Actually, the focusing distance is usually more than adequate to keep the photographer rather away from the framed insect so to avoid any disturbances or unwanted interactions.
I love it!Sigma 120-400mm f/4.5-5.6 AF APO DG OS HSM Telephoto Zoom Lens for Nikon Digital SLR Cameras
