Description — Leica 11845
The Leica 11845 R Focus Module 2x f/5.6 is a telephoto prime optical component designed exclusively for the Leica R mount system. Built to serve full-frame DSLR photographers within the Leica R ecosystem, this module operates at a maximum aperture of f/5.6 and relies entirely on manual focus — there is no autofocus functionality present. With no image stabilization included, users working at telephoto distances will want to use a stable platform such as a tripod to maintain sharpness.
The module's full-frame lens format ensures it is designed to cover the complete image circle of full-frame Leica R bodies without compromise. Filter thread size and weight data are not available in the current specifications. This is a purpose-specific component for photographers already working within the Leica R system who require telephoto prime performance and are comfortable with manual focusing disciplines.
