Originally posted by Kunzite Right now it's not a given that it's anything other than a Pentax. We have to wait
Is there a patent out for a Pentax 70-200 f4? That would be an early decider of whether it is an entirely Pentax lens, and a new design too.
A patent would need to be registered as I presume the optical design for such a new Pentax lens would be substantially different from the DFA 70-200 f2.8. It could not merely be a shrunken down DFA 70-200 f2.8. The optical design of, for example, the Nikon 70-200 f4 is clearly different from the Nikon 70-200 f2.8, ditto for the Canon f4 and f2.8 70-200's.
