Overview

The Leica Summicron-T 23mm f/2 ASPH is a compact, well-built lens equivalent to 35mm full-frame, offering fast, near-silent autofocus and internal focus design. Its optical design includes two aspherical surfaces to control aberrations, and it performs well wide open for subject isolation. However, the lens is limited to the Leica T mount, restricting compatibility. Build quality is high, with a metal construction and included hood. It suits photographers seeking a discreet, high-quality normal-angle lens for the Leica T system.
