Overview

The Astro-Berlin Pan-Tachar 125mm f/2.3 is a rare, uncoated pre-WWII lens known for its fast aperture and distinctive 'Tachar look' with better contrast than other Astro lenses. Its optical design uses four air-spaced elements to correct spherical and chromatic aberrations. The lens is heavy (1 lb 9 oz) with a long 350-degree focus throw and 60mm filter size. It is extremely rare in rangefinder-coupled Leica mount, likely a special factory order. Suits collectors and enthusiasts seeking a unique, fast vintage lens with character, though adapters for modern cameras can be expensive.
