Yes, I often use it for that too. Larger bottles (1.5l) can be easily transported because they can then be additionally fixed with the upper strap. For smaller bottles (0.5l), the bag is also high and tight enough so that the bottle does not tip out.

Yes, every break that often to that above. Større flasker (1,5l) can also be transported for di du da can fikse dem med den øvre stroppen. For at least one flask (0,5l) he posen høy og tett nok til at flasken ikke tipper ut.

I have the backpack myself because it is so "unobtrusive" as a photo backpack. Meanwhile, I stow two Sony bodies with lenses (a macro and a 70 - 300 mm from Tamron) and a Minolta 28 - 80 mm in it, so your Canon should pose no problem.

Each has sekken selv fordi den ser så "upåfallende" ut som en fotosekk. I can handle Sony lenses with lenses (macro and 70 - 300 mm from Tamron) and Minolta 28 - 80 mm are there, but Canon doesn't cause any problems.
