I have a camera bag, but it is big and bulky. It has enough room for lots of gear (not a bad thing), but it is too bulky to take when I go hiking. I'd like to get another bag that is a little smaller and less bulky. I don't really want a backpack (kind of bulky), but it would be nice to have something that I could strap to my back. Can anyone recommend this bag? http://www.bhphotovideo.com/c/product/392367-REG/Lowepro_34736_SlingShot_100_AW_Bag.html I met someone with a bag like this and thought it would be a nice bag to have. I have the 30D with the 17-85mm and the 50mm f/1.8 right now. Would the SlingShot 100 be large enough for my stuff, or should I consider the SlingShot 200? If anyone could recommend anything else, that would be great too.
