I have a Lowepro Event Messenger bag that I use to haul around a pair of Rolleiflex 2.8Es with lens hoods attached. I also fit a dozen rolls of film in the main compartment. The dividers are Velcro so you can move and re-arrange them if you need. The meter, Rolleinar closeup adapters and other odds-n-ends go in the front zipper compartment, and there's a slot in the back for a tablet or other similarly slim computing device. Best of all, it's cheap (under $50 IIRC). It served me very well on my trip to Paris for 10 days last October, and it looks sufficiently unlike a camera bag as to be inconspicuous when out and about.
