How to use

Attach the lens to a compatible Leica M-mount camera by aligning the mount marks and turning until it locks. Use the viewfinder or rangefinder coupling to achieve accurate focus; fine adjustments are performed on the manual focus ring. Set the aperture with the aperture ring to control exposure and depth of field—wider apertures (f/2.8) for subject separation and lower light, smaller apertures for increased depth of field and sharper overall images. Metering and shutter speed selection are handled by the camera body or your chosen exposure method.

Usage recommendations

For best results in street and travel scenarios, carry the lens mounted on a compact M-body to minimize handling time. Use apertures between f/2.8 and f/5.6 for a balance of subject separation and overall sharpness. When precise critical focus is required, use a focus magnifier or zone focusing technique. Keep the metal mount and front element clean, and store the lens in a padded case to protect the finish and mechanical components.
