What to expect#

Aperture control: lenses with a manual aperture ring work directly; electronically controlled lenses (no ring) need a smart adapter or one with a built-in aperture lever.

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

Image circle: Four Thirds lenses are designed for a smaller sensor (≈2.0× crop), so expect heavy vignetting on a full-frame Sony E-mount body unless you use its crop mode.

Frequently asked questions#

Will Four Thirds lenses autofocus on Sony E-mount?

No — adapted lenses are manual focus on this combination.

Does a Four Thirds 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.
