Sigma 50-500mm f/4.5-6.3 APO DG OS HSM Lens Review
From DxOMark Conclusion :
The Sigma might not have the build and outright image quality at the longer end of the zoom range of the premium marques, with Nikon’s own offering being recently redesigned and improved in lots of meaningful ways. But, given the extra versatility from the wider zoom and the savings of around $1,000 over the Nikon badged lens, the Sigma is hard to ignore.
