i have three of these: http://www.adorama.com ...gy.html?RRref=productPage
one carries my camera and lenses, another carries flash/lighting stuff, the third is a catch all for whatever I need that day. Having a shorter handle for carrying by hand and an additional shoulder strap is great and it has more than enough padding.
i think you can get all your gear in there no problem.
I carry: 6D, 70-200 2.8 IS, 85 1.8, sig 35A, Tokina 16-28 2.8, 24-105 f/4, SL1 and a small manual 50mm
Never seen these before. I guess I may be adding another bag to my collection. Should make my wife extremely happy.
