The bag depends on the camera of course, but for small stuff (5x7/5x12) I have a Zone VI "cooler" white bag that can hold the Canham 5x7, several lenses, my Minolta Spotmeter F, cable release, and a half-dozen or more holders. If I'm packing the 5x12, the bag holds the camera plus five holders, and a second canvas Whole Foods grocery tote has the meter, lenses, cable release and Sawtooth Designs darkcloth. If i'm feeling particularly gutsy/insane, there's a Tenba shipping bag that hauls around the 14x17 plus the Saitta bag for the 5 14x17 holders. The canvas tote makes another appearance with that outfit hauling the two lenses, cable release, and meter.
