Sigma 50-500mm DG OS HSM lens F4,5-6,3 (95mm filter thread) for Nikon (Electronics)
The Sigma 50-500 I shot for about 6 months in operation and approximately 2000 images. As a camera, the Nikon D90, the new Nikon D7000, was now in use. At the beginning of the lens had to be returned because the autofocus did not work really reliable
