No AF, etc., but DOF works fine with the converter. The TC14A
is OK with the 20mm f2.8, but not great (the 16mm fisheyes are
really excellent on the TC14A), and the *AIS* 28mm f2.8 works
well, even making a decent macro lens on the 2X... It should
be good (not as good as without it...) on the other lenses
mentioned, and is good on the 180 AF.

Look at the end of my Nikkor evaluation list, on my web
page, under "I babble", for a description of all the Nikkor
TC's...

AF and MF are optically identical, but the MF is more
nicely constructed, and nicer to use for MF (though the
AF isn't bad for this). Teleconverters work well with
some lenses, OK with some, not well with some (put the 20
somewhere toward the right in this grouping...;-).
