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.

Thanks!
