On the older screwmount Pentax cameras and MX's, the trick was to give the shutter release a very quick flick, like you were flicking a crumb off a picnic table. The mirror would go up, but the shutter wouldn't fire until you gave it a follow-up push. Not an easy or reliable way to get mirror lock-up... Regards, Bob S.
