The K10D is a native PTP device. Use PC for normal communication with the computer. PC-F is a fallback option that uses USB 1.1 Full Speed communication rather than USB 2.0 High Speed communication and is only useful for systems that do not behave correctly with USB 2.0. PictBridge is only used for connection to a printer.
Note that the options used for the K-x, K-7, and later models are different, and allow for USB Mass Storage Class communication as well.
