I'm looking for a somewhat smaller backpack that will accommodate a Rebel series body with attached 70-200 f/4. The backpack will be used as a "carry all" pack, but needs to be good for day hiking a few times a year. All the gear I need it to hold is the aforementioned Rebel body with attached 70-200, my 18-55 kit lens, a flash, a decent tripod, plus the cords that go along with a camera. I would like to have the ability to carry a water bottle, either with a dedicated pouch or a carabiner-style attachment, and a small pouch for snacks.
When I went to the local camera shop I didn't really like the Lowepro Flipside or Fastpack line; they just didn't appeal to me for some reason. I'll revisit them if thats the consensus of what the community recommends. Every backpack that I find that holds an attached 70-200 is huge with lots of compartments that I don't need; I have no intention of carrying 4+ lenses any time soon. I'm looking for something with the smallest possible size that can still do all the things I want it to do.
