It seems like a shoulder bag would be too small for the job. Check out the Lowepro Commercial, that's one of the shoulder bags that will hold all your stuff.


A backpack would be more comfortable to carry around as the bag which contains all your stuff is not going to be weightless. My Nature Trekker will do and it's comfortable for the trips (largest carry on backpack for flights). I don't find myself carrying all my gear (in fact, not even half) when I'm going for a photo shoot event. I need such big volume only when I'm travelling for months and I need to take all my gear.


A bag with wheels makes sense too, depending what you're going to use it for.
