I'm looking for a decent bag for my M645. Right now I have to use one bag for the camera and extra lens, and another to carry film, 2 extra magazines, and my Sekonic meter. I usually have the camera set up with the 80mm lens and prism, and keep the 150mm and WLF in my bag. Most bags are designed around a 35mm SLR or DSLR, and just don't really work that well. What bag do you owners of medium format SLRs use on a regular basis?
