Sigma APO DG OS HSM 737306 150-500mm
85 out of 100 low confidence 9 reviews
Users are overwhelmingly positive about this Sigma 150-500mm lens, praising its excellent image quality, sharpness, and value for money compared to expensive Nikon alternatives. Many note it is heavy and requires good technique, especially at 500mm, but the optical stabilization works well. A few mention autofocus issues over time or in low light, and the f/6.3 aperture limits indoor use, but overall it is highly recommended for wildlife and outdoor sports photography.
