From Tokina:

We have thoroughly tested all current Tokina interchangeable lenses (Canon EF mount) with the Canon EOS R mirrorless camera and the Canon EF-EOS R mount adapter.

The results confirm that the current Tokina lens models showed no issues in general operations, with the following exception:

  • Tokina AT-X 17-35 F4 PRO FX

Issue: the image Cropping/Aspect ratio would be fixed at “1.6x (Crop)” and cannot be set at “Full (3:2)”.

We are currently preparing a firmware to fix the issue, which will be specifically notified about in due time.

Furthermore, when using Tokina APS-C format lenses (Tokina DX lenses), in case the Cropping/Aspect ratio is set otherwise, it is necessary to reset it on “1.6x (Crop)” manually. When shooting with a different Cropping/Aspect ratio setting, vignetting is likely to occur.

For any questions about the compatibility of Tokina interchangeable lenses with Canon EOS R mirrorless cameras, please contact us via the contact form.

  1. I have a old discontinued tokina 17mm f/3.5 that seemed to work fine for the brief time I tried it on my R. My type of photography generally does not include focal lengths wider than about 28mm, but I keep it around, just in case. I've had wider lenses, but sold them all, virtually unused. If the 28-70 f/2 weren't so big, heavy, and expensive, I'd be more interested.
