Does the Tokina atx-m 23mm f/1.4 E fit the Sony a1 II?

Yes, it mounts — both are Sony E. But the Tokina atx-m 23mm f/1.4 E is an APS-C lens on a full-frame Sony a1 II, so the body uses only the centre of its sensor (crop mode, lower resolution). The 23mm then frames like 35mm.

What "crop mode" means here

The Tokina atx-m 23mm f/1.4 E is designed to cover an APS-C sensor, and the Sony a1 II 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 II produces with a full-frame lens. Framing follows the crop: 23mm looks like 35mm.

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

FAQ

Does the Tokina atx-m 23mm f/1.4 E fit the Sony a1 II?
Yes. The Tokina atx-m 23mm f/1.4 E is a Sony E lens and the Sony a1 II is a Sony E body, so it mounts. Because the lens is APS-C and the body is full-frame, the Sony a1 II 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We do not publish autofocus behaviour — FitMyLens stores only the specs that are fixed facts of the product (mount, focal length, maximum aperture, sensor coverage).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 II.

What focal length will I actually get?
35mm equivalent. In crop mode the Sony a1 II reads an APS-C-sized area, so the 23mm frames like a 1.5× longer lens.
