Thank you for using Tokina products.
We have thoroughly tested all current Tokina interchangeable lenses (Nikon F mount) with the Nikon Z6, Nikon Z7 and Nikon Z50 mirrorless camera using the Nikon mount adapter FTZ.
The results confirm that current Tokina lens models showed no issues in general operations with the following exceptions:
Tokina opera 50mm F1.4 FF
Issue: Compared with general conditions depending on aperture value AF speed might be slower.
Tokina AT-X 70-200mm F4 FX VCM-S
Issue: AF communication error. However, the lens will operate normally in manual focus mode.
Please, note that due to mount adapter FTZ specifications, the following Tokina lenses do not AF but will operate in manual focus mode:
Tokina AT-X M100 AF PRO D
Tokina AT-X 107 AF DX NH Fisheye
Tokina AT-X 107 AF DX Fisheye
For any question about compatibility of Tokina interchangeable lenses with Nikon Z6, Nikon Z7 and Nikon Z50 mirrorless camera you can contact us at marcom@cokin.com.
