Well, I can fit a 6x9 folder in my cargo pockets, but only if it's a svelte one with no RF on top and no bulge for the lens on the front. Which pretty much limits it (in 6x9, anyway) to my Wirgin Auta and Voigtlander Rollfilmkamera. My Super Ikonta B and Mamiya 6 (6x6, the latter with masks for 6x4.5) have too much bulge for lens clearance. My Daiichi Zenobia (in sensible original black) will fit, though. Speed Graphic is right out; that calls for a backpack.
