Lens OverviewLeica 11254

The Leica 11254 90mm f/2 Summicron-R is a manual focus prime lens built for the Leica R-mount system, covering a full-frame image circle. Designated as the 3rd Cam version, this lens represents a specific production iteration of the Summicron-R 90mm line, making it relevant for collectors and photographers working with compatible Leica R-mount bodies. With a maximum aperture of f/2, this telephoto prime offers meaningful light-gathering capability for available-light shooting and selective focus work at the 90mm focal length.

The lens is a pure manual focus design, requiring the shooter to engage directly with the focusing ring — a deliberate, tactile experience that many photographers prefer for precise control. Weighing 560g and accepting 55mm front filters, the lens is a reasonably sized full-frame telephoto prime. Its Leica R mount makes it a dedicated R-system optic, though many photographers also adapt Leica R glass to other camera systems using third-party adapters.

There is no image stabilization present in this lens, which is consistent with the optical design era. For anyone invested in the Leica R ecosystem or looking to adapt a well-regarded 90mm prime, this Summicron-R 3rd Cam is a compelling manual option.

DescriptionLeica 11254

The Leica 11254 Summicron-R is a 90mm prime lens built for the Leica R mount system, providing full-frame coverage for compatible bodies. Featuring a f/2 maximum aperture, this telephoto prime offers solid performance in available-light situations and allows for meaningful background separation at this focal length. The lens is a manual focus design — there is no autofocus — placing full control in the hands of the photographer through direct interaction with the focus ring.

Weighing 560g and accepting 55mm front filters, it is a practical size for a full-frame f/2 telephoto prime. There is no image stabilization in this lens. The 3rd Cam designation is an important detail for buyers, as it determines which Leica R bodies this lens will properly communicate with.

This is a prime lens with a fixed 90mm focal length, dedicated to a single perspective without the optical trade-offs of a zoom design.

ProsLeica 11254

  • Fast f/2 maximum aperture provides strong light-gathering capability at the 90mm focal length
  • Full-frame coverage makes it compatible with full-frame Leica R-mount bodies
  • Fixed 90mm prime focal length delivers a dedicated telephoto perspective with no optical compromises from zoom design

ConsLeica 11254

  • Manual focus only — no autofocus support, which may limit use in fast-paced shooting scenarios
  • No image stabilization, requiring careful technique at the 90mm focal length
  • Leica R mount has a limited selection of native compatible bodies, and the system is no longer in active production
