TheSigma Sport 150-600mm f5-6.3 DG is a large, heavy, quick-focusing lens for Nikon F mount cameras. The maximum aperture isn’t huge at f5-6.3, but the lens issharp throughout its zoom range, andthe image stabilizer works very well. A modern supertelephoto zoom lens with great performance, if you don’t mind carrying a bit of extra weight (it’s about 3kg by itself). Cosmetic condition is decent, with paint and finish wear; glass is clean, with minor dust, and function is good. Includes hood and case.
