It is definitely time for me to invest in a new bag, since my current one is barely better than a plastic shopping bag. I've got a very specific idea of what I want and looked around quite a lot, but not found what I'm looking for. I'm going travelling soon, and so need a shoulder bag, preferably with a zip and velcro flap to prevent theft. I'll probably only be taking my 450D and 18-250 Tamron because I want to avoid taking too much expensive equipment. So I'll need quite a small bag, quite flat, that would have a compartment for my camera with lens mounted, and maybe a bit of space for other items like wallet etc. All the bags I've seen either don't have a proper compartment for a camera and lens, or have way too many compartments for equipment. All suggestions would be much appreciated!
