I'm having a hard time believing these lenses will focus faster than Canikon's USM/SWM ultrasonic lenses. If they will, that'd be great, but Pentax never has been faster.
Yes, apparently. Larger, higher torque, higher speed, more precise.
Why do we refuse to believe Ricoh isn't Hoya? - and neither is it Pentax Corp? They don't release something until it is ready at the their standard.
Until it is shown to be otherwise, I choose to believe this is a superior lens that will surprise us. It needn't focus
faster than a USM/SWM lens - it need to focus
as fast and
as accurately. The coatings (superior final IQ) and the build are the differentiators.
I choose to believe the D-FA* is a truly professional quality lens.
My default belief is Ricoh does it right unless they've made a mistake (and mistakes will be rare). Hoya (and to a degree Pentax Corp) did it wrong unless they made a surprise (K10D).
