I've been using the backpack for two weeks now and I'm very pleasantly surprised. With the pockets and compartments it is surprisingly practical. I have a Sony Alpha 6400 with the 70-350mm and four other lenses in the lower compartment, which fits completely without any problems. There is then space at the top for the day trip. I also like that you can remove the divider between the top and bottom compartment if you need a backpack with a very large, one-piece compartment. The side pocket is ideal for quickly accessing the camera. Outside, in the side pocket, I have my Rollei travel tripod. Since this is made of carbon, I don't notice any lateral imbalance, which fits very well. The tripod can also be attached easily, a well-rounded thing. The backpack is still very dirt-repellent, which I like. The waterproofing will definitely need to be refreshed at some point, but it shouldn't be a problem. The backpack stays upright empty and full, which is good. It's a shame that the floor isn't protected against dirt with rubber or artificial leather, there's still room for improvement. The wearing comfort is remarkably good, both when walking and on the bike.
