I use the case without the separator insert. I put in a larger lens and above over it the camera with screwed Standartobejktiv. In the mesh pockets the charger and the charger cable are suitable. In the front pockets, a battery and lens covers. On the inside of the "lid" is still a zippered mesh pocket for a bag (if it is pouring rain) and memory cards.
It fits my complete camera equipment in this one bag. She looks sturdy and you can attach the supplied strap at different locations. As Gürteltasche this massive bag is probably not appropriate. Waterproof against smaller quantities it seems to be.
Overall, I am very happy with this purchase.
