I would like opinions on camera backpacks please. I have an Olympus e420 and a few lenses. I'd ideally like it to have separate padded pockets to hold these and maybe a place to carry a tri pod on it as well as other accessories. It would be nice to find one that can hold my iPad as well, but that's not necessary. I'd like more of a backpack style because I think that it would draw less attention to the fact I'm carrying some pricey stuff. I've checked all over online for a sturdy one but am not sure what to get as some people are saying things about the stitching pulling out, zippers breaking, etc. Thanks in advance!!
