I shoot with a Canon 5D Mark III, and I keep a battery grip on the body all the time. I have about 5 lenses, but don't always travel with all 5. A 16-15, 24-105, 70-200 (the F4), 100 Macro, and a 50mm.
I also have some accessories, and occasionally lug along the 600 EX-RT flash. I currently have a Lowepro Compu-Daypack, which is a decent bag, however, with the 5D and grip the camera compartment is VERY tight. Also, when placing lenses in the upper compartment, it only has one zipper, so opening the bag is kind of a risky procedure (lens could fall out).
I've looked online at the Tamrac and Lowepro offerings, and some seem nice but I'm not a huge waist-belt fan. I'd really like to stick to a backpack, and ideally like the idea of a small amount of space for day trips, walking around the city, etc.
Any suggestions?
