Well yeah, that's part of why walking around being prepared to photograph while doing something else or just going for a walk with the Yashica is so much more pleasant than the Mamiya. I take a small shoulder bag that holds the camera, filters, lens hood, plenty of extra film and my Luna Pro SBC (not a small meter) and it's all still tiny, or just the loaded camera with lens hood and the meter in a (jacket) pocket. I COULD just carry the 645 with one back and lens, but even then it's much larger and heavier. Start taking the bag I keep it in with three 120 backs, the Polaroid back, several extra inserts, three lenses... the thing weighs more than my 4x5 kit with six film holders.
