I shoot the new Fuji instant pack film--the 3.25 X 4.25 size--and I was wondering--what cameras are made for this size film (new or used)?

Obviously you can put a polaroid/fuji back into any 4x5--but is there a camera especially made for this size, or something smaller than 4x5 that would take the pack film in some way?

What got me thinking about this is looking at the 6x9 Linhofs--and wondering if they would take the pack film (I still don't know yet). I'm especially interested in handheld use.

It would be cool to have camera that I could use handheld and shoot polaroids...(I mean, fujis...)
