Does the Tokina atx-m 11-18mm f/2.8 E fit the Sony a1?

Yes, it mounts — both are Sony E. But the Tokina atx-m 11-18mm f/2.8 E is an APS-C lens on a full-frame Sony a1, so the body uses only the centre of its sensor (crop mode, lower resolution). The 11-18mm then frames like 17–27mm.

What "crop mode" means here

The Tokina atx-m 11-18mm f/2.8 E is designed to cover an APS-C sensor, and the Sony a1 has a full-frame one. The lens mounts and works, but the body reads only the centre of its sensor to match the lens — a lower-resolution file than the Sony a1 produces with a full-frame lens. Framing follows the crop: 11-18mm looks like 17–27mm.

If you want the Sony a1's full resolution, use a full-frame Sony E lens instead — all 76 of them are listed here.

FAQ

Does the Tokina atx-m 11-18mm f/2.8 E fit the Sony a1?
Yes. The Tokina atx-m 11-18mm f/2.8 E is a Sony E lens and the Sony a1 is a Sony E body, so it mounts. Because the lens is APS-C and the body is full-frame, the Sony a1 switches to crop mode and uses only the centre of its sensor, producing a lower-resolution file.

Will autofocus work?
We do not publish autofocus behaviour — FitMyLens stores only the specs that are fixed facts of the product (mount, focal length, maximum aperture, sensor coverage). Check the Tokina product page for AF support on the Sony a1.

What focal length will I actually get?
17–27mm equivalent. In crop mode the Sony a1 reads an APS-C-sized area, so the 11-18mm frames like a 1.5× longer lens.
