Folks: I’ve spent my life reviewing camera bags that are attached to the photographer (me). Now that I’m older and wiser I realize that the correct way to use a camera bag is to have it be attached to an assistant (i.e., someone younger and stronger!). Suppose that I have an assistant who can carry a small photo backpack or similar. Let’s say that bag needs to hold a Canon 5D, 24-70/2.8, 70-200/2.8, 300/4, 1.4 teleconverter, and 16-35/2.8 (to keep the size manageable maybe the 24-70 could be replaced with a 50/1.4). It should have a rain cover in case the weather turns bad. But most importantly I want to be able to put a lens away and take out a new lens while the backpack is still on the assistant’s back.
Has anyone found a good photo backpack to be used like this? There are a lot of good photo backpacks, but the classic ones are designed to be taken off, set down on the ground, and then unzipped for flat access (if you did this while the bag was still attached to someone, the lenses would tend to fall out). The newer designs tend to innovate by trying to make it easier for the person wearing the backpack to get to some part of it, but that’s not quite what I want.
