Kr and remote shutter control

I recently bought a Kr to upgrade from my ds. Very nice but disappointed to find no jack socket for a remote. I want to shoot long night exposures but the manual says shutter open as long as button pressed but I don't want to hang on to the camera for 5 mins. Is there another remote that I can use which will do this for me, an IR one perhaps
thanks in anticipation

On the k5, when in bulb mode you can select that first remote click opens the shutter, second closes it. You might be able do the same on a kr, you'd need to check the manual.

yes it is the same with the k-r

thanks for that. It has pointed me in the right direction. i'll check with a Pentax store to see the best thing to buy.
Thanks again.
