G'day, wondering if anyone can help me with any advice or experience with camera bags. I'm looking for a day-to-day carry round bag that will fit in a EOS 30D with grip & 70-200IS lens and extender easily with space for an extra lens, few memory cards, batteries and filters etc and maybe a flash. I want something that I can have on my shoulder so I can see it easily for security and access it easily to get it out quickly without having to put the bag down. Also I do not want it to look too much like a camera bag so as to not advertise. I have a couple of Lowe Pro Belt pack type bags 'Off Trail 1' and 'Off Trail 2', one is a bit too small and the other is a bit too big, but either way both look like camera bags any way so I do not feel to comfortable carrying them if I am in and around town. I was initially drawn by the Lowe Pro Slingshot 200, but it is too small to get in a body with extender and 70-200IS and again it still looks like a camera bags. I am now drawn towards the Crumpler bags as they seem to just look like a trendy bag and not a camera bag. Does anyone use one or know if they are any good and if so what kind of size one I'd need? There seem to be loads of different sorts and I'm finding it a nightmare from the web site to find a suitable one. Does anyone have any other suggestions of other makes? Also does anyone know if they are well sealed to be dust proof?
