I can put in and no problem, my D90 with handle and nikkor 18-200, SB-900, a 28, 50 and 85 mm without any problem, and the additional inner compartment can store two three odds.
The "foot door" air resistance, and once the foot attached, it hardly moves, handy when you want to run ...
The only less concerns the main opening. Indeed, once the full bag it is more difficult to open and close quickly due to the small tab "Rain" (I ask). But nothing too bad.
Ps: do not expect to store a thousand objects in the side pocket because it is relatively narrow.
