Sigma 105mm f/2.8 EX DG Medium Telephoto Macro Lens for Nikon SLR Cameras

The Sigma 105mm f2.8 EX Macro delivers superb, distortion-free images throughout its broad focus range, from infinity telephoto to 1: 1 (life-size) macro, as close as 12.3" without accessories. Its non-rotating front lens group makes it easier to work with polarizing filters and has a focus limiter.A "focus-free" mechanical design allows the lens to auto focus without any interference from the manual focus ring. This makes it easier to hold the lens without affecting the speed or normal operation of the autofocus function. Rugged mechanical construction also makes it durable enough for even the heaviest use required by professional photographers.The Sigma 105mm f2.8 EX Macro features the new deluxe external EX finish. These features and other Sigma optical advances, including an uncommonly broad range of focus, make this an ideal lens for a wide variety of applications, from nature photography to portraits. A handy screw-in type metal sunshade makes it easier to rotate a polarizing filter.

    Amazon.com Product Description
    Optimized for Nikon digital SLR cameras but also compatible with film SLR cameras, the Sigma 105mm f/2.8 medium telephoto lens allows a greater working distance between the lens and the subject, helping it excel in all shooting ranges. The increased working distance of the lens is ideal when taking the picture of a flower among several branches, or an insect on a leaf. The narrow angle of view helps simplify the background, while the shallow depth of field makes it easier to handle the composition. The lens also offers a super multi coating that reduces the flare and ghosting that tends to occur when using digital SLR cameras, helping create crisper, sharper photos. And thanks to the Dual Focus (DF) system, the lens is easy to hold during autofocusing, but also offers smooth and positive action should you choose to focus manually on images. Other features include a minimum aperture of f/32, a screw-in lens hood that supports the use of circular polarizing filters, and a minimum focusing distance of 12.3 inches. Offering a 35mm equivalent field of view of 178mm on a digital SLR camera, the lens carries a one-year warranty.

    Sharp lens5
    Sigma did a fine job of building this lens. I get really detailed shots in both telephoto and macro. This is one of their best.

    Great lens!5
    I have been using this lens in my studio for close to a year now. I'm very happy with the results I've been able to achieve and would recommend it to others.

    Images I've shot with this lens have appeared on clients websites, advertising in magazines, and used in various printed materials.

    At this time I use it exclusively in my work in the studio along with my Nikon D80.
