(From company literature) Sigma Corporation is pleased to announce the launch of the new 17-70mm f/2.8-4.5 DC Macro lens. It can be used with wide variety of subjects and it is an ideal large aperture standard zoom lens for digital SLR cameras featuring an APS-C size image sensor.

This lens has a minimum focusing distance of 20cm (7.9") 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 f/2.8 at 17mm wide angle and yet it is compact, with an overall length of 82.5mm (3.2") and diameter of 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.

Prema onome što sam do sada vidio sa te sigme, jako dobar za te pare (kolko se sećam nešto oko 340€). Ima zavidan macro, filter je 72 mm, i što je čudno, samo na 17 mm je 2.8, odmah iznad kreće da raste blenda. Verovatno će neki biti protiv kupovine ovog objektiva pričajući da su neki drugi bolji.

Moje mišljenje je kao za sve, uzmi probaj pa ako odgovara pazari.
