Overview

The Nikon Nikkor 135mm f/2.8 Ai-s is a compact, lightweight telephoto lens praised for its outstanding optical performance and sharpness, especially from f/5.6 to f/8. It exhibits softness wide open and significant chromatic aberrations at f/2.8, though these improve when stopped down. Build quality is high, with a smooth focus ring and retractable metal hood, though some note the Ai-s version uses cost-cutting measures compared to earlier Ai models. It offers excellent value for its fast aperture and is ideal for nature and portrait photographers seeking a portable, affordable prime.
