I have 2 x Nikon D70  and a Nikon D2h all with lenses mounted on them in  it, a Sigma 80-200 HSM EX, Sigma 24-80 HSM EX and Tokina 12-24mm f/4
I do have 2 other lenses that I can keep in the bag, 105 Nikon Micro and Nikon 28-200mm f/3.5-5.6G ED-IF AF that go where the lens hood and flash dome are. But they are loaned out to a friend for the weekend.
I also keep my 15 PowerBook in the back pocket, but there is not a easy way to get a photograph of it in the bag.
I love this backpack except that it is very  heavy with the 2 extra lenses and the PowerBook in it.
