Reason:
My camera fits just right laboriously in the appropriate tray and the Velcro can be closed with inserted camera only about half. You always have the feeling (because of the relatively stable bag shape) that the Velcro rises every moment. In addition, the second compartment is characterized quite useless. When I plug in my spare battery there, the velcro is hard to close. I also the risk is too great that by the pressure that the battery on the display / lens (depending on how one camera pushes into the tray) exerts, is too high, preventing the camera may be damaged.
Conclusion: a good bag for smaller cameras as the PL210.
