I'm got my new 40D two weeks ago and I need a good bag, I've been looking at tamrac and lowepro, but I'm not sure which I should go for. Could anyone give me some advice? I'm looking at the lowepro slingshot as I've been using one for college for a while, but I'm not sure how good they'd be for photo gear. Are the sling desigs good in comparison to others? Also, I'm wondering if I should get some nice lens cases, but I'm unsure whether I'd use them if I get a good backpack for my gear. All I have at the moment is 1 Lens and the 40D, but I'm going to get another 2 lenses by the end of the year. So, I don't really need a huge bag, I think. Anyone have any advice for me please?
