This task is performed, the backpack perfectly. The laptop (15.6 inches) fits. The camera (Nikon D5100) fits. The additional lens (Tamron AF 70-300) fits.
In the compartment for personal belongings fit, whatever we fly needs: purse, cell phone, headphones, Kindle (with sheath In order for the trade is even as good as completed, but much more is no longer needed, too. :)
Good processed it seems to me so far also to be. Have absolutely can not detect any defects. I'm just curious if it sees soon visible scuffs on the bottom of the backpack. I'll take it, but not to, because of the state at the bottom rubber feet are attached to protect the pack from dirty floors at least a little.
The only drawback I see is that there is no lock for the camera if you want to take out the camera on the Sling function. You open the side compartment and should thereby ensure definitely that the backpack is kept parrallel to the floor, because the camera could solve otherwise. But this subject is quite practical and once you get used to it, this represents no further problem. (If someone knows other remedial or did I miss a catch, this review can be like comments and I'll correct them :))
