Quote:the optical design itself is actually not new - it is based on the classic Tokina AF 100mm f/2.8 AT-X Pro macro (for DSLRs that is).
Which itself borrows its optical design from the smc Pentax-D FA 100mm f/2.8 macro (launched in 2004), the optical design of which is a fine-tuned version of that of the smc Pentax-F 100mm f/2.8 Macro (launched in 1987).
What did you say about Tokina having 'to cut corners 'in order to achieve a 40% lower price tag'?
