How is the MLU activated with the 645N and 645NII? Pre-lock or separate lever requiring cable release?
It has both mirror lock and mirror prefire. No need to use remote releases for either. Set via the switch around the release level. One position is mirror pre-fire (2s) if the self timer is programmed that way (otherwise 12s). Another position is mirror lock. One press on the shutter release flips up the mirror. Another open the shutter.
