[QUOTE="pforsell, post: 504042, member: 7240"] I know, I have two of those. One with the contact pin swap (for my D4S + D3S + D3X) and one without (D2X). I only use them for macro though, since the image quality leaves a lot to be desired unless stopped down two or three stops. [offtopic] An interesting hypothetical TC would be a TC-12A using similar tech as TC-16A but with only 1.25X magnification and thus only half a stop loss of light. But that would increase the sales of the old superteles to ballistic. Think for a moment: AI-S 400/2.8 + fictional TC-12A would produce a pseudo-autofocusing 500mm f/3.5. If someone would produce such a gadget using modern coatings, aspeherics and ED glass, it would be capable of very high IQ. I'd pay $1000 for such a gizmo in a heartbeat. [/offtopic] [/QUOTE]
