Tokina 11-16mm f2.8 DX in Nikon D600
I tried my old Tokina wide angle lens in Nikon D600. It appears that it was registered by teh camera as an FX lens. I tried another one (Tamron 18-270mm DX) and it shows the cropping box and the reduced file size. Why does the Tokina wide angle DX behaves like an FX lens?
