The TC14 or 14B (identical optically) are fine with the 80-200mm f2.8
(useable at f2.8, very good over most of the frame by f4, excellent by
f5.6). The rare TC14C is somewhat better with this lens (excellent over
most of the frame by f4, hard to tell from the best primes by f5.6). The TC200/1 is not a happy combination with this lens (not bad resolution by
f5.6 [f11 effective aperture...], but contrast is low). The TC20E (which
must be modified to allow it to fit non-S/I Nikkors) is better, but not
ideal (good by f4, very good by f5.6 - an' I have one to spare, modified,
mint in box, $375...;-). For greatest ease of use and best optical
quality at wider apertures, I would choose a Nikkor 1.4X...
(I, fortunately, have a "C"...;-)
Hope This Helps
