Mac,

Have you tried your 80-200 AF-S with Nikon's latest TC1.4? Just curious about how the TC affects the AF speed.

I purchased a used Nikon AF-I TC 1.4E about a year ago but never really worked with it other than to ensure it was functional so cannot comment on any difference AF speed.  My concern was IQ and could not discern any significant degradation with the Nikon 80-200/2.8 AF-S.  Thought has always been that if I needed a little extra reach, I could pull it out.  The TC 1.4E was more of a curiousity than a real need.  I have never had a lot of confidence in converters though never owned a high quality one like the Nikon.  Given the lens motor speed and an effective aperture of f/4.0, I wouldn't expect any AF speed degradation in normal lighting.
