Smart adapter for converting EF lenses to NZ mount. - Brand: fringer - Model Name: FR-NZ1 - Type: Mount Adapter - Included Items: Warranty card - Color: Black Thank you for viewing. I have been using this adapter almost permanently attached to my Nikon Z5. Although there seem to be some EF lenses that don't work, all of my lenses worked. The tracking AF for super-telephoto lenses also performed reasonably well. APS-C specific lenses could also be used with cropping on a full-frame camera.
