My blad kit all fits into a lowepro AW 'Orion' Hip back that is also convertible to a backpack. I can get my Hasselblad body, 50mm, 80mm, 150mm, and a darlot petzval, my 'great hassel lens', a spare back, 10 rolls of film and my gossen Luniasix 3s into the bottom half. You can get the Lowepro lens cases to fit around the waist belt if you needed one, or just put them inside the top half of the backpack when you want to go fully laden. It makes for a very compact and modular set up.
