I have and really like the Lowepro Flipside 400AW (and a couple of other Lowepro bags, too). TheFlipside400AW holds an impressive amount of gear -I can carry a gripped 7D, two white zooms (100-400mm, 70-200mm f/2.8 IS MkII) and 4 black lenses (10-22mm, 17-55mm f/2.8, 85mm f/1.8, 100mm L Macro) all with hoods, plus a 1.4x Extender II and a 430EX II. The various filters (CPL, NDs), cables, cleaning supplies, etc., go in the front pocket.


That's probably a bit big for your collection - the Flipside 300 might be a better fit, both for your gear and your budget.

Like many choices with photo gear (and in life), that's going to involve some compromise. A shoulder/sling bag is not going to be comfortable when worn for long periods with relatively heavy gear (the 24-70mm is called 'the wedding brick' for a reason). A backpack-style bag will be more comfortable to wear, but less convenient.


For comfort, don't forget about the camera strap, either. Based on recommendations here, I picked up a BlackRapid strap - it's great, and much more comfortable than a neck strap. I can put the strap over my shoulder, then put the backpack on over that. With the Flipside, to change lenses I pull the camera up and to the side, then slide the bag off one shoulder and pull it around the other side so it flips down (as designed) and provides a platform for changing lenses on-the-fly. Sounds more complicated than it is.
