This pack is really a great option for anyone wanting to be mobile. It has lots of places for lenses, and extra things. Though its not huge, it will give you ample breathing rooom. The quality of the material of the pack was surprisingly good. And it looks really well made. Best thing about it is, just throw it over your shoulder and go. Lots of external ties for tripod and such too. And I feel confident that my 20d is well protected. This is a must have for the mobile photographer with a moderate set of equipment, or anyone that just wants the stuff easy to carry around.
