I adore this bag; very solid build and very spacious. Currently I have my DSLR body, 3 kit lenses, a zoom lens, and plenty of other little tidbits like filters, cords, etc. tucked in there -- with room to spare.
It easily surpasses any other camera packs I've had in quality.
The only downfalls:
- there isn't really a space to sneak a laptop in comfortably
- to switch out lenses etc. you have to take the pack off entirely
