This backpack camera bag is an excellent buy.  Don't be fooled by the price since it is exquisitely made and quite solid.  There's lots of pockets and it's easy to customize the interior.  Most of all, the bag is comfortable on the back and can be carried by the handle as well.  The only concern I can think of is that I wish it had some extra padding although I have found this not to be a problem despite some rough handling with the backpack full of my Canon lenses and 10D body. 

Question: How is the camera strap?
Answer: excellent buy
