Leica's compact vintage 90mm — 3-element Elmar f/4 in chrome, a collapsible telephoto.
The Leica Elmar 90mm f/4 (3 Element, Chrome) is a compact vintage telephoto for the Leica M rangefinder system in chrome finish. Elmar designates Leica's f/4 prime class. The chrome finish indicates an early M-system production era. Leica M mount.
f/4 maximum aperture. 90mm focal length (full-frame). Chrome finish. Compact 3-element optical design. Manual focus with rangefinder coupling. Leica M mount.
The Elmar 90mm f/4 is one of Leica's earliest M-mount 90mm designs — smaller and lighter than the later Summicron-M 90mm f/2, trading two stops of aperture for a far more compact form. The chrome finish and compact optical design are characteristic of early Leica M production. A classic combination for discreet travel use on M bodies.
On the used market this is a vintage compact chrome 90mm M-mount prime. Condition checks: front element for marks or haze, aperture blade condition (oil-on-blades common in older lenses), focus ring damping, rangefinder coupling. Leica M mount. Verify production era and correct M-mount coupling via serial number.
