I am trying to buy a bag now that will have room for the upcoming Olympus Pro lenses, the 7-14 and the 300. Currently I have two E-M1 bodies, 12-40 Pro, 40-150 Pro, E14 TC, 60MM Macro, plus flash, Polarizers, and Misc Stuff. Currently it is all in a Lowepro 300 AW back pack, but I don't think there is room for the addition of the two new lenses that I plan to buy. I travel world wide and I am mostly outside shooting. Not adverse to a different backpack, or a small roller bag that converts to a back pack. I read the other thread here and those are mostly shoulder bags, which are small and don't hold much, and gear can be inaccessible in the field. Would like to buy a carry system that will accommodate the two new Olympus Pro lenses. Any suggestions?
