I transport is a Sony A7 and 4 lenses (but not a big telephoto), 2 flashes, accessories and my tripod (to the tripod receptacle) and am thrilled with the Felxibilität.
The classification can be superbly adapted to their own desires and offers more than enough space for the equipment of an average amateur.
The carrying system is very comfortable thanks to the wide hip belt and allows easily transporting heavy equipment. I could feel again pack 5 kg in the backpack and would not be overwhelmed on long journeys.
Access to the rear compartment is done by rotating the backpack while the hip fin is still closed. For me personally, a very good solution, because it so both hands free so you "handle" to and all parts can be reached immediately. And I also this type of access appears the safest in terms of theft.
The workmanship is as usual very well from Lowepro.
Who has to carry little Eqipment or a completely unobtrusive solution examined is however certainly better off with a messenger bag.
