Comments about Sigma Sigma 70mm f/2.8 EX DG Auto Focus Macro Lens for Sigma Cameras:

I use the Sigma 70mm Macro on my Sigma SD-14 to take product shots for use on our website and [...]. The lens is tack sharp at all apertures! Also very contrasty, which is good. The lens is made very well and the focus snaps into place very easily. The auto-focus could have been better with a hypersonic motor, but it still focuses quick enough and accurately. I really like this lens and it seems to do a little better than 1:1 which is a bonus. You can literally press the front glass right on top the subject and still be in focus. Not much working distance so I am probably going to compliment this lens with the 150mm macro as well. Sigma didn't have such a great reputation about 10 years ago, some of their lenses were good but mostly bad. They have sure turned that around with real good glass and designs and they are making some very fine lenses now that are better than Nikon and Canon's. The build quality is also much better. The coatings are also far improved over the older lenses. This is a fantastic lens that I highly recommend. I mostly shoot Leica, but for my business I use the Sigma products and I have been very happy with them.

Comments about Sigma Sigma 70mm f/2.8 EX DG Auto Focus Macro Lens for Sigma Cameras:

I was looking for a full frame 70mm Macro prime lens and as all of my lenses are Canon L glass, I was disappointed that Canon did not make a full frame prime 70mm f/2.8 lens. For this reason only, I looked at the Sigma 70mm f/2.8 EX DG macro. The results I am getting from this lens are exceptional. The focus is very accurate, even in dim light and corner sharpness even at f/2.8 is very good. I am very pleased with my purchase.

The only small complaint I have with this lens is that you have to manually switch to manual focus should you need to.

I use this lens for product and wedding photography.
