Leica Macro-Elmar-R 100mm f/4 - Leica R Mount

The Macro-Elmar-R 100mm f/4 is a dedicated macro lens for the Leica R system, offering a 1:2 magnification ratio natively (reaching 1:1 with the dedicated bellows or Elpro attachment). It is highly regarded for its flat field of focus and exceptional sharpness across the frame, making it ideal for close-up work, product photography, and document reproduction. Its relatively slow f/4 aperture allows for a compact and lightweight design. Potential buyers should ensure the long focus throw is smooth and consistent, as any grit in the helical will be magnified during precision macro work. SDS checks for internal dust and ensures the aperture diaphragm is clean and responsive. The lens mount should be inspected to confirm if it is a 2-cam, 3-cam, or ROM version to ensure compatibility with your specific Leica R body.
