Yes, but the PL is only in use in P-mode (green button pressed in Hyper-P or if using P-mode with program shift).
It would have been cool if PL was in use with other modes as well, FI when changing aperture or shutter speed in Hyper-P.
And having "sports" PL available in Av might be even more useful than TAv.
BTW, K30 seems to have ISO available in manual mode. But I don't know if it works with stop down metering.
