Trouble with Pentax K-x with Rokinon 24mm f/1.4

Hello,

I just got a Rokinon 24mm f/1.4 lens for my Pentax K-x. The lense is a K mount, it fits, and it's supposed to be compatible, but I'm unable to take any pictures. The F/--- is blocking, and I'm unable to select an exposure time. When I press the exposure button, nothing happens. I've got it on manual mode, and MF. I've tried it in Av mode, but no change. Is there something in Settings I need to change to be able to use this lense?

Set the aperture ring to "A"

Number 22 in the C custom menu, set it for number 2.

On a DSLR, you should never turn the aperture ring away from "A" unless you're shooting with a bellows, manual extension tubes, etc. Doing so otherwise will compromise the accuracy of metering, remove aperture info from the exif, and limit you to M mode.
