Quote:The Nikon TC is +/- 0.03mm measured across the faces of the bayonet at 4 X 90°. I've never noticed anything wrong other than I don't like TCs in general.
A 500 mm Tele doesn't react on a difference of 0.06 mm (that's what ± 0.03 means ) With a (heavy) wide-angle, it's another thing. Mind you, you did not measure the play between mount and lens. This adds as well as the play between adapter and lens. So very soon you come to ± 0.3 mm if it comes worst to worst.
Sure you can buy, measure and send back to some extent. If you have enough nerves to spend on this selection...
