The camera will show the firmware version on the display if you turn it on while holding down the MENU button. The latest firmware version including SDM/HSM support is 1.30.
The firmware and instructions
for updating can be found from a couple of Pentax websites, for example
Customer Support - Official PENTAX Imaging Web Site
Its a piece of cake if you just follow the insructions carefully.
