I used this case once and then I went to buy another. 2 controls the camera "canon" are not accessible when in the case (including flash). The thong (lousy incidentally) was taken down when I pulled it lightly. The case is in two parts, a base and a front guard attached by two pressures. To take a picture, you have to win a pressure allowing décapuchonner protection that frees the goal and commands. If it was well this part of the case would remain attached to the base of the case by the remaining snap but being hurt loose as the second pressure by the weight of the detached part. I do not know if I am quite clear in my presentation when I sum> the stew.
