Advantage, it is absolutely easy ... Why this purchase, I have a bag of 11 kg of gear (including stand), but sometimes I like to travel light, a box, optical, ... yes the night on the beach, souvenir photo .. . not need all the stuff, this little bag is super nice, a flash, an optical (not 500 mm) and the box with its optical, possibly filters, and accessories in the front pocket of the bag. Ass bag is rigid, it is useful if you filed your bag in the mud, or puddle. Aesthetically nice.
