The Sigma 105mm f/2.8 EX DG OS HSM Macro Lens for Nikon AF Cameras delivers superb, distortion-free images throughout its broad focus range, from infinity telephoto to life-size (1:1) macro, as close as 31cm without accessories. A Special Low Dispersion (SLD) lens and one high refractive index SLD lens provide excellent correction for all types of aberration and distortion. Its non-rotating front lens group makes it easier to work with polarizing filters. A focus limiter helps divide the broad focus range into more manageable chunks.
The HSM (Hyper Sonic Motor) ensures quiet and high speed autofocus as well as full-time manual focus capability. The "focus-free" mechanical design allows the lens to autofocus without any interference from the manual focus ring, making it easy 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. An ideal lens for a wide variety of applications from nature photography to portraiture.
