Assuming you can do without AF, the rare TC14C is excellent, with the
TC14B slightly behind. The TC16 is for AF'ing non-AF lenses, and is
not as high quality as the TC14's. The TC201 (and Vivitar Macro 2X)
will fit, but optimum apertures make the working apertures
impractically small. I have not used the AF 3rd party converters, but
have heard negative comments about physical rigidity.
Hope This Helps
