Lens Overview — Leica 11844
Key Features — Leica 11844
Leica R Mount: Native compatibility with Leica R system lenses and bodies ensures a direct, secure optical connection without adapters.
1.4x Magnification Factor: Extends the effective focal length of compatible Leica R lenses, increasing reach for telephoto shooting applications.
Full-Frame Coverage: Designed to cover a full-frame image circle, making it compatible with both full-frame film and digital Leica R bodies without vignetting.
f/4 Light Loss Factor: Using this module introduces approximately 1 stop of light loss; effective maximum aperture of the combined system will be reduced accordingly.
Manual Focus Only: Fully manual focus operation suits the deliberate, precise shooting style typical of Leica R system users.
Teleconverter / Focus Module: This is an optical accessory module, not a standalone lens — it attaches between the camera body and a compatible Leica R lens.

Description — Leica 11844
The Leica 11844 R Focus Module is a prime, telephoto-category optical accessory designed exclusively for the Leica R lens mount system. Built to serve full-frame DSLR camera platforms, it provides a native connection point within the Leica R ecosystem for photographers who prefer deliberate, hands-on control over their imaging setup. With a maximum aperture of f/4 and manual focus only, this module is tailored to a measured shooting style where precision matters more than speed.
There is no image stabilization, so a stable shooting platform is recommended, particularly at telephoto working distances. As a prime optical design, it maintains a fixed configuration rather than offering a variable zoom range. The Leica R mount ensures direct compatibility with other Leica R system components, keeping the optical chain within a consistent, well-established ecosystem.
Filter thread size and weight data are not available in the current specification set and should be confirmed with Leica directly before purchase.
