i feel that your logic is flawed. why do you need to bring all your lenses to wherever you go? pick and choose the appropriate ones for what you are going to shoot, no need to lug every single lens around.
and why 24-70L and 70-200L? sounds like some L-BBB to me.
Hmm, I think I just use 10-22, 18-55 and 55-250 for now.
Thanks everyone for your help~!
Understand! Will stick to this 3 lens! =)
10-250, u had covered every inch with minor overlapping. Mayb u can pratice carry any 2 lens for shooting. By thinking ahead what's ur environment and ur subjects can save u some troubles.
