At last I have a camera roller & backpack camera bag roll in one package. I really need this bag before my back pains gets worst because of lifting heavy gears during wedding coverages. I decided on the Airport Take Off because it has backpack straps that you can pull out if you need to carry the bag instead of rolling it. It is usually not a problem to roll a bag like this around the city, but when your climbing stairs, having rough floors or floods it’s nice to have the option to throw it on your back.
Versatile, Amazing camera bag! Very useful for my needs.
Here's a look at the Think Tank Photo Airport Takeoff Camera Bag. Converting from a rolling camera bag to a backpack for when the going gets even tougher.
