Both the TC16A and TC201 are useable, but will disappoint if you wish to
maintain the high level of performance your lens is capable of - only the
TC14/14B/14C converters work really well with this lens (by one stop down,
performance is quite excellent, and it is useable wide-open). The TC14
version is occasionally seen used at good prices.
Hope This Helps
