Old vs. New Tamron 90 mm macro MF

Pentax Bob · 03-15-2014, 12:14 PM

I just saw an add at B&H Photo for a Tamron 90 mm f-2.8 MF macro adaptal lens model B-57 -100. It is new and comes with the typical 6 year warranty. How is this different than the old Tamron Model 72 B? Does it use the Tamron PKA adaptal 2 lens mount?

Hello,

I could find little to no info on the B-57-100 lens on Tamron's US and Japan web site. Comparing our spec's to the old Tamron Model 72 B they appear to be identical with cosmetic changes. Since the 72-B spec's list AD-2 mount, I am positive the current version would have the same.
