Hi guys!
having a technical issue with this combination on Nikon D500. When using the Kenko TC with a different lens on this camera it will work fin. When using the Tokina on the D500 it will work fine. But the combination won't work. it says F0 and neither aperture nor autofocus can be used. I thought this is a combination which is used frequently so I must be doing something wrong. I tried different options like turning the camera on and the mounting tc first and then the tokina. Mounting tc and then turn on camera and so on. Putting them together, mounting them and only then turn the camera on or mounting the combo with camera turned on... No way to make it work. Happy for any suggestions
