Sigma 17-70mm F2.8-4.5 DC MACRO Overview

This lens has a minimum focusing distance of 7.9" (20cm) throughout the entire zoom range. Maximum magnification of 1:2.3 enables close-up photography like a macro lens. The new lens design and multi layer lens coating reduce flare and ghosting, which is a common problem with digital cameras. A Special Low Dispersion (SLD) lens and two aspherical lens elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range.

This lens offers a large aperture of F2.8 at 17mm wide angle and yet it is compact, with an overall length of 82.5mm (3.2") and diameter 79mm (3.1"). It performs superbly even in relatively low light conditions indoors or at dusk.

The lens design incorporates an inner focusing system, which ensures fast AF speed as well as prevents the front of the lens rotating, making it particularly suitable for use with circular polarizing filters and petal shaped lens hoods. This lens is also equipped with Zoom Lock Switch that eliminates ’Zoom Creep’ during transportation

Sigma 17-70mm F2.8-4.5 DC MACRO user reviews

    "This was an upgrade for my Canon xti. What a difference. Crisp pictures, great colors. I use this as a walk around lens, but the macro feature is amazing. If you are on a budget, this is the lense to buy."

    "I bought the Sigma 17-70 for my D100 after a recommendation by a fellow wedding photographer. I was not sure how this lens would compare with my Nikon glass but I have been very happy with the results. This lens has not left my camera since I first mounted it. So far I've shot over 5000 images in just 2 months with fantastic results. Very good color reproduction, fast focus, zoom is smooth. I love the macro feature, something I lacked with the Nikon 24-120 VR. Well worth the price!"

    "I bought this lens to shoot Las Vegas, mostly at night. I was not disappointed! Crystal clear shots, fast 2.8 and ability to capture night shots with a steady hand and no tripod on my Canon EOS 30D. At less than 390.00 this is a great medium range lens. I am a fan of the powder coat finish (some are not) and the overall feel of the piece is one of quality. Zoom is stiff, not sloppy. No play or loose fittings, good weight and great all day size and feel. This lens is a huge step up from the Canon EFS 18-55 kit lens and far superior in every way. This is my first Sigma and first venture away from Canon glass... no regrets"

    "Dieses Objektiv ist ein guter Ersatz für das Kit-Objektiv, welches Canon zu den Spiegelreflexkameras der EOS-Serie hinzufügt. Das Obejtktiv ist Top verarbeitet, die Abblidungsleistung lässt für Amateure nicht zu wünschen übrig.
Top Preis-Leistungsverhältnis! Ich kann nur eine aufempfehlung aussprechen!"
