I got this to house my Sony Alpha R7 and the lenses I so far have for it, especially when I am traveling long distance. Knowing my camera was resting directly on my back gave me a lot more peace of mind that I wasn't going to be stolen of fall out because I didn't do up the zipper properly.I recently used took the bag on a trip to England using it as my personal item/laptop bag. I think this was what impressed me the most about this bag normally I would have had to put my camera into my carry-on bag and lose space in there. With this bag, I was actually able to carry not just my camera and lenses but also pack a couple of t-shirts, and books in it along with an ipad, 2 portable hard drives and other things. In fact even though the bag is rated to carry only very small laptops (13.3") the reality is I could fit my 17" work laptop (Toshiba Tecra Z50-A-17W) into the camera compartment. In fact if not for the rounded corners of the bag relative to the length of my personal HP Envy-17 3090NR laptop (17.3"), that too would have fit.It is a very light weight bag and I have had no problems carrying is for long periods of time. The straps are also fairly generous, so I could wear it on top of my thick -50degree Celsius rated mid-length dawn feather winter coat.One thing missing in this model is the waist strap that's on another model of the bag to allow easier (sling bag type) access to the camera without having to take off the bag
