> which teleconverter can i use in autofocus
> mode or manual mode
The recommended TCs for that lens are the
TC-14B and TC-301. Nikon does not make a
teleconverter that will maintain AF with
the 300mm/f4.
I've used the TC-201 with the 300mm/f4. It
works fairly well -- fine for prints up to
5x7, and OK on 8x10's.
Nikon used to make an AF converter called the
TC-16A. I've played around with one a 300mm/f4.
Optically the combination's OK, but the TC's
AF focusing accuracy isn't acceptable on long
lenses.
Third-party companies do make real AF TC's.
In fact, almost everybody BUT Nikon makes AF
TC's. I don't know which (if any) of them
would be a good match with the 300mm/f4.
