Sigma APO DG OS HSM 737101 150-500mm
85 out of 100 low confidence 8 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. The optical stabilization is highly effective, and the build quality feels solid and professional. However, the lens is noted to be very heavy, and its slow aperture (f/5-6.3) makes it challenging for indoor or low-light sports photography. Some users also reported autofocus issues after extended use or in low light.
