Hi all,

I am struggling at the moment . I am trying to set up my Canon 7D with the Tokina 10-17mm lens. I have the NN5 and I also use the arca-sytyle clamb.

Does anybody has working settings please? My lower rail settings btw are at 53.5 mm. I tried on the upper rail every mm between 90 and 99mm

Thanks
Kai
