I just purchased/inherited (it was supposed to be for my hubbies video camera) a Lowepro Flipside 400 AW pack. I have tried a couple of times to arrange it, but just haven't been happy. The question that I have is, how do you pack it? Can people post pics of how they pack their backpack? (Not really needing to see just the 400, but backpacks in general.) Do you leave your hoods reversed on the lens? Do you allow for quick design change. Sometimes I will want the longer lens on the body, sometimes the shorter. What I am trying to fit in is below 5d canon 24-105 f4 canon 70-200 f4 canon 50 f1.8 flash There is other miscellaneous stuff (white balance, trigger, spare battery, etc) but I can fit that in with out too much trouble. Any feedback about how you handle stuff is appreciated.
