I've been using a Sinar P2 a lot lately, and I absolutely love everything about it except one thing it's a cumbersome behemoth! So, I'm looking for a smaller, more field-friendly camera. I know what features I want/need, but don't know which cameras have them. So, I'd like to tap your combined knowledge pool to help me narrow down the search.

I'm looking for:
(1) asymmetric tilt and swing on both standards (I've been spoiled by the P2 on this one)
(2) must be able to fit in a backpack (could even be a large backpack; folding is nice, but not necessary)

That's pretty much it! If you know of cameras that fit this description (or other features that might be important), please let me know.
