This is an extremely good bag for professional or semi-professional photo gear. I am only selling it because at nearly 70 I no longer want to carry as much around as I could in this, and I want  a different style of bag. At c2.8kg empty, it is quite heavy, but it is well padded with very comfortable straps. The main bag can be divided into at least 12 compartments. You can easily fit in 2 camera bodies, 4 or 5 lenses (subject to size) a flashgun and lots of filters and accessories. It is so deep that flashguns can be stood upright and short lenses double-packed. It has tripod and monopod straps, a large laptop compartment, and so many pockets of varied size that I am not sure I discovered them all! It is sturdy and carries a waterproof cover (which I never needed to use). It hasn't been out very much, and is very clean.
