I am afraid that even Pentax acknowledges that there is no improvement in focus speed with the SDM lenses. They are just quieter. Note that their product description doesn't even talk about speed: "advanced SDM system that ensures smooth, quiet autofocusing operation using the supersonic motor installed in the lens body"
