There are no known issues with general operation with Tokina lenses when used with Canon full frame mirrorless camera. But Tokina do state that the Tokina AT-X 17-35 F4 PRO FX lens has one issue about the image Cropping/Aspect ratio. This will be fixed by Tokina in a future firmware update.
Looking for the Canon EOS R availability? Due to high demand of the Canon’s full frame mirrorless camera, here is the Canon EOS R in stock tracker.
Compatibility of Tokina interchangeable lenses with the Canon EOS R
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.
