What to expect#

Aperture control: these are mechanical lenses with aperture rings — set the aperture on the lens and shoot in aperture-priority or manual.

Focus: use focus peaking and magnification in the viewfinder. Exposure metering works normally because the camera meters through the lens at working aperture.

Frequently asked questions#

Will Leica R lenses autofocus on Sony E-mount?

No — adapted lenses are manual focus on this combination.

Does a Leica R to Sony E-mount adapter affect image quality?

A glass-free adapter is just a precisely machined spacer, so image quality is unchanged when it is built to the right thickness. Cheap adapters can be slightly too thin or thick, which shifts the infinity mark.
