Overview

The Nikon Reflex-Nikkor 1000mm f/11 is a catadioptric lens offering extreme reach in a compact barrel. Optical strengths include sharp results when used on a sturdy tripod with high ISO, but it suffers from fixed f/11 aperture, manual focus, and optical vignetting. Build is compact and light for its focal length, but handling requires technique and a hefty tripod. It suits patient wildlife or aircraft photographers willing to work within its limitations.
