good save Ryan! amazing photo there.
dltorre, thanks for sharing the video. certainly some good advice and his images look good. Phase One makes a good system for those who can afford it, lol.
Regarding the strap, I have a combination neck strap/hand stap, so when i mount to the tripod, i usually clip out the long section and then clip the short strap through the metal frame of my three way head as an extra precaution if the QR plate releases accidentally.
BTW, the Pentax 645D (and i believe 645N and maybe others too) have a very prominent knob for Mirror up on top of the camera which is really nice. I often shoot in darkness, and try not to use any light so my eyes can stay adjusted, and being able to feel all the buttons on the camera easily is really important.
