do you mean transport, like on an airplane, or to carry a smaller subset while out and about.
There is a big difference.
I have several photo backpacks and 2 shoulder bags.
the biggest backpack can carry 2-3 bodies, my 70-200 F2.8,,my 300F4 and perhaps 5 other lenses and my 1.7x AFTC and 2x TC and a flash or two.
the smallest back pack can carry 2 bodies my 70-200 F2.8, my 10-20, my 28-75 F2.8 and a TC
I have a shoulder bag that can hold 2 lenses or a lens and body, that I take with me, while keeping one lens on the second body in my hand. (note the 2 lenses exclue the 70-200F2.7 or 300F4
