Sigma EX500 /F4,5 DG HSM

Zitat: Overall this lens performs extremely well and produces some excellent shots. In the specialist areas where it would be used, such as Wildlife and sports, it proves easy to handle and, just as importantly, carry. It´s supplied in one of Sigma’s semi-hard pouches, this time with a sturdy shoulder strap and is much easier to transport than a metal carry case. The pouch still provides adequate protection. Although not lightweight, the lens is not such a burden that it wouldn’t get used for its intended purpose. Far out-performing, for example, our 170-500mm zoom, if you have a genuine need for this type of lens, you won’t be disappointed. In summary the main positive points of the Sigma 500mm f/4.5 APO EX DG are: Good build and finish Fast quiet autofocus Very usable wide open Manageable for its type Close focus distance is good. Negative points are: Lacks a little contrast Hood a little short for the focal length.

Zitat: This rugged, well-designed APO lens boasts an unusual degree of convenience, with features like its built-in grip, rotating filter drawer, and factory-replaceable front element of optical quality glass that offers a built-in level of scratch protection.
