Thinktank Airport Acceleration v2.0 &nbsptype_Lens & Sensor Cleaning it might actually be aThe Thinktank Airport Acceleration v2. 0 is a roughly carry on sized bag designed to hold a fair bit of camera equipment. I say "roughly" because with the backpack straps stowed, it takes a bit of squishing to get it down to the standard 9 inch carry on thickness. That's right: this carry on bag is also a backpack, if you hate yourself. Holds a complete multi camera setup, including very long lenses: interior dimensions are approximately 17x33x45.
