I upgraded my camera bag a few weeks ago. I’ve chosen the same brand so it is a Lowepro again, but a Magnum AW this time.
I’m pretty satisfied with it so far. I can put all my stuff into it (see my gear here): a camera body, two lenses, two speedlights, chargers, batteries and still have some room for some future developments or a backup body.
It seems to be padded very well for protection.
I also purchased a Belt strap with it. It’s easier to carry the full bag on my shoulder with the belt fastened around my hip and the belt prevents the bag from slinging when not needed.
