Yep. Glass type tc.
Refund received. Have contacted B&H asking about their FotodioX product. If anyone here has any experiences with the FotodioX adapter I would appreciate hearing them. Looking to use it with Pentax DA14, DA 21, DFA 100, Sigma EX DG 24 f 1.8 on a Nikon D800. The ebay one I have returned would not lock the these lenses into position, and as you had to use them in full manual mode, when ever you adjusted the aperture ring, the lens would turn and come off.
