Hello everyone, I am very new to photography but also very passionate. I just bought a D5000 and am looking for advice on a good camera bag. It has to be compact, have space for a couple lenses and some other accessories, and hopefully have double zippers so I can lock the pouches when I'm traveling in urban areas. I was looking for a easy access sling style bag that can be used when backpacking and camping, maybe it could fit in my backcountry pack? I know its sort of a random/specific question but any recommendations? Thanks!
