You have made a tactical error - just one camera bag.
You need to have several
special purpose camera bags. That way, you can hide more cameras.
Lets see, a small bag in the car, either for a 35mm Olympus and three lenses, or the larger 35mm bag, with three bodiesand a number of lenses and flashes, or the other small bag, with a 645, a back, a finder and a 70 mm lens, or the medium size soft bag, for the 645 Pro, a couple of lenses, and a couple of backs, plus meter, or the semi-hard case with the C330 or C220 and three lenses, or the large soft padded case with all the Metz 60 CT1 and CT2 stuff, or the soft Olympus bag, currently holding the new (to me) Koni-Omega, which needs its own bag, etc., etc. ...
Clearly, I don't have a problem.
