Help!! TC-14EII connection problem..
I have a dimming problem using my Nikon 1.4xTCII (second version) with my D800E coupled with my 500mm f/4 VR lens..
The focus motor is working as I can see, hear and feel it hunting for acquisition but the aperture blades are fixed closed nearly.
Once I take the TC off the camera and lens works perfectly.
The lens is nearly new, only used the TC once with the body which is also nearly new.
The teleconverter is only a couple of years old and hardly used so I don't think it's a wear problem as there's hardly a mark on all of the contacts, to which I have thoroughly cleaned using professional Eclipse and a cotton bud (Q-tip)..
Can anyone help?
