This is exactly the backpack I was looking for. The camera I use is 10" long with the lens and hood. This fits with a little extra room in the side pocket of this bag. I've been using a sling bag but I have to tilt the lens up and I always get fear of not getting it right and falling when I pick it up. This bag solves that problem and gives me much more peace of mind. I also found that I can use the dividers to angle it slightly so that the body sits up a little to make it even easier plus the footprint. I started with the small divider and made a little bump to put it in, but then moved on to the larger divider. I made a ramp with it, and the lens slides right into place. It's better than any other bag I've ever seen. I've used it before. It has lots of options to divide it any way you like, or you can leave it wide open and use it as a big padded container. The dividers feel nice and rigid and hold the shape I make very well. back is a firm gel. That's OK, but it allows the air channels to stay open so my back doesn't get sweaty. It's fairly well protected, but it also comes with a rain cover. I found out it's reversible in case I don't want to advertise what I have in my bag. The flap at the top is extra security as this bag can be fully unzipped for easy access to all your gear. The flap attaches to hooks in the middle of the pack. If there's one thing I would change, it's these hooks, as I've never liked the way they work. It's a minor gripe because I just don't use them, and the bag's other features far outweigh that small issue. The overall quality of materials and stitching is extremely good. Even the top handle feels more substantial than other bags I've used. Overall a fantastic bag. Highly recommended.
