I've been using the backpack every day on city tours for almost a week now and don't want to give it back. The top compartment isn't huge, but it can still fit a thin sweater, a rain jacket and a 0.5l bottle of water or something similar. (The bottle also fits well into the outside of the tripod compartment, unless otherwise stated.) I can even fit my very flat 14-inch notebook into the notebook compartment (but so far only tested "on the green table"). During the trip I stored all the papers that you might need there; With a little fiddling, a DIN A4 envelope with tickets etc. fits in. Two negative points for me: 1. The buckle of the chest strap tends to "jam" when closing, meaning you have to push the two parts very precisely into each other so that the buckle can be closed. This can definitely be optimized! (I'm glad that the backpack has a chest strap and I use it regularly.) 2. I was hoping that the interior division in the lower part could be used more flexibly. I haven't managed to move the partitions so that my little alpha6000 has a firm hold in them (and is accessible from the side flap). Now the backpack is not offered specifically for such a small system camera (only larger DSLRs are mentioned), so I don't want to devalue the backpack because of that, but perhaps the note will help other interested parties.
