Product Description

A medium telephoto macro lens which is designed for traditional and digital SLR cameras, its lens power layout produces an excellent optical performance. The lens coating cuts down ghost. The DG lens is designed to reduce the influence of harmful light caused by reflections from the digital image sensor. Its outstanding optical performance provides the ultimate correction against lateral chromatic aberration and distortion. This lens boasts compact dimensions of 2.9" (maximum diameter) and 3.7" (overall length). It has a filter size of 58mm and, at just 15.8 OZ, is also extremely lightweight. The minimum focusing distance of 31.2cm (12.2in) is capable of macro photography with a maximum magnification of 1:1. It is possible to enjoy photography from life-size close-up to infinity. This lens is equipped with a "Focus Limiter Switch" that limits the AF range so improving the speed and accuracy of auto focus. It also incorporates a Dual Focus (DF) system that is designed to make the lens easy to hold during auto focusing. The large focus ring offers smooth and positive action whilst focusing manually. A screw-in hood is included, for convenient use of circular polarizing filters. This telephoto macro lens has an equivalent field of view of 178mm on a digital SLR camera (when used with the SD10).

Sigma 105mm f/2.8 EX DG Medium Telephoto Macro Lens for Pentax and Samsung SLR Cameras Review

I was looking for a prime lens with macro capability and since I already had the Pentax 50mm f/1.4, I needed something in the 100mm range. There were two options: this Sigma and the Pentax equivalent that was slightly more expensive. I've seen some great recommendations for the Sigma on photo.net, so I decided to go with it and I don't regret that choice. If you've been using cheaper lenses, this lens will show you why it's worth investing more into a good prime lens. I've been using it for macro photography (flowers) and for portraits with great results. I also recommend the Sigma DG 58mm Multi-Coated UV Filter to go with it.
