Lens Review
Introduction | One of the sharpest long telephoto zoom on D800 | Sigma APO 50-500mm f/4.5-6.3 DG OS HSM Nikon performance | Sigma 50-500mm F4.5-6.3 APO DG OS HSM Nikon Versus Nikon AF-S NIKKOR 80-400mm f/4.5-5.6G ED VR | Conclusion

Sigma 50-500mm F4.5-6.3 APO DG OS HSM Nikon mounted on Nikon D600:

On a 24-MPix Nikon D600 the Sigma APO 50-500mm f4.5-6.3 performs very well indeed. Achieving a DxOMark score of 20 points, the lens is one of the highest scoring super-telephoto zoom that we’ve seen.

Although the sharpness varies a bit over the zoom ratio (it performs best at 50mm) the 14P-Mpix score places this lens very close to the Nikon 80-400mm rivals for sharpness. An average Transmission of 6.6T is slightly disappointing (it’s measured at 5.3-7.5T across the zoom range) but figures for distortion, vignetting and CA are all very good for a lens like this.
