Pentax Z10 lens joining??

Hey everyone,
I was just wondering if anybody could help me? I have just purchased a z10 but have not received it yet to have a look, but i wanted to know how u attached the lens, is it screw on or does it click on?? Its just i am also looking at lenses and want to purchase the right type.

Thanks and i appreciate it

(also, is there an online manual for this camera, i cant seem to find one via google)

Hi Spenck,
The Z10 has a bayonet mount. If you want a manual try here

You need to look under PZ10 because it's a US site and that's the name the camera was sold under there.
