Lens Overview — Leica 11078

The Leica Elmarit-S 45mm f/2.8 ASPH CS is a wide-angle prime lens built specifically for the Leica S-System, mounting via the Leica S mount. Designed for the medium format camera system, this lens delivers a fixed 45mm focal length paired with a maximum aperture of f/2.8, offering a useful balance between light-gathering capability and compact optical design for a medium format prime. As a prime lens, it encourages deliberate composition and delivers the consistency that professionals expect from a fixed focal length optic.

The lens supports both autofocus and manual focus operation, giving photographers the flexibility to switch between shooting styles depending on the situation. With an 82mm filter thread, it accommodates a wide range of screw-in filters for creative and technical use in the field or studio. Weighing 1,120g, it reflects the robust build typical of medium format glass.

Image stabilization is not included, so shooting technique and support equipment become important considerations. This lens is categorized as a wide-angle optic within the medium format format range, making it a strong candidate for architecture, landscape, and environmental portrait work on compatible Leica S-mount bodies.

Key Features — Leica 11078

45mm Medium Format Prime: Fixed 45mm focal length on medium format delivers an angle of view equivalent to roughly 35mm on full-frame, well-suited for architecture, landscapes, and environmental portraits.

f/2.8 Maximum Aperture: Offers useful light-gathering for a medium format wide-angle prime, allowing handheld shooting in lower-light conditions.

ASPH Optical Design: Aspherical lens elements reduce spherical aberration and distortion, contributing to edge-to-edge sharpness across the medium format frame.

Central Shutter (CS): Built-in leaf shutter syncs with flash at all shutter speeds, a significant advantage for location and studio work with flash lighting.

Autofocus and Manual Focus: Supports both AF and MF operation, giving photographers the flexibility to switch between modes depending on the shooting situation.
