i need a sling bag that can carry the 70-200L (not mounted) and my 5D2 gripped with 24-105 mounted and laptop.
i've been looking at the kata 3n1-22 and have heard many say the supporting strap is weak and bouncy?
i like the lowepro sling.. but looks like there's no place for me to store my 70-200L.
any others? need it for an upcoming trip to SD-Sea World.. so would like to carry my 70-200 and sit back and shoot the whale and dolphin performance without getting wet...
