Product Description

Sigma's Macro 70mm F2.8 EX DG is a large aperture medium macro lens suitable for shooting the smaller things in our world that exist virtually unseen. A macro lens is one, which will focus on a subject close enough to render it "life-size" on the image plane in your camera. It also has a "flat field" front lens element so that it can shoot images of flat objects such as artwork or postage stamps and be tack sharp all the way across the image. This Sigma Macro 70mm F2.8 is ideally suited for taking pictures of insects or other small creature where a closer approach to the subject would scare them away. This greater distance also allows the photographer more flexibility in lighting the subject with natural light reflectors. 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 enabling ability to shoot with critical sharpness regardless of distance. So don't miss the tiny insects, flowers of the world or the details in a stamp or coin collection or a piece of embroidery all of which are seldom noticed but offer a fascinating world if you look closely enough. Capture them with the Sigma Macro 70mm F2.8 EX DG.

Sigma 70mm F/2.8 EX DG Macro Lens for Nikon Digital SLR Cameras Review

I've never been a big fan of Sigma Zoom lenses, but their prime lenses are top notch. I've been using the Sigma 105mm and 50mm macro primes on my Canon full frame bodies so I decided to pick this lens up for my Nikon D300 to give me a 105mm equiv lens for that system.

In a nutshell, this lens is fantastic. It is very sharp corner-to-corner on my Nikon D300. It is sharp wide open at f/2.8 and stays sharp up until about f/11, where it starts to soften just a bit. Lens construction is very sturdy and typical of the top-end sigma primes. Autofocus speed is adequate but not as fast as the best Nikon lenses. It also makes a little more noise when focusing. Manual focusing is excellent with a very smooth and precise feel. I really like this lens and it may be one of the sharpest prime lenses on the market. I highly recommend it.
