As a beginner, I find the pocket just perfect. The allocation by the inner workings can be changed individually by velcro. The spare battery keeps me still very good services and as an addition to this bag a great addition. However you get into only 1 camera and more than 1 objective in this bag. For me, this bag quickly became too small, so that I could no longer use. Also, opening the bag bothered me immensely after a while. This is fitted with a zipper is applied very funny in my opinion. One has the flap, recover to open the zipper. Well because there are better techniques. But everyone must decide for themselves.
