As much as I like the stealth bag that I got, it just seems too boxy to be practical for carrying out and about. I can foresee me ending up with a backpack of some sort for it, but again the times when I would want to use a backpack, chances are Ill be wanting to carry more important things with me instead!
The stealth does quite handily fit the body, 50mm, 17-85mm and 100mm lens though for storage purposes. I pointed out to Binary the other weekend that the rain cover is actually it bit of a let down, theres 2 slits in the top that are there for the shoulder strap to run through. If its raining enough I can foresee the rain running down the strap and through those slits. Yeah it still offers protection, but its a bit of a design flaw. For weatherproofness Id rather take the Jessops bag, as it fits inside my Osprey backpack, which has a proper raincover!
Test the bag in the shower?
