The bag has, inter alia, a (theoretically) tailored cutout for the camera with envelope. For the HDR-AS100V that currently most widely sold Action Cam from Sony, this recess is about 1.5cm long. Although you can fix via Velcro, but it remains a bit shaky. The protection is certainly given anyway. But if I have a "tailor-made" casing the manufacturer to buy, I would also like a perfect fit. In addition, the bag is much larger than I would have expected. But I would of course need only read the product description carefully. Anyway, this bag z. B. is twice the size of the protective bag for my camera. Thus, but you can then also accommodate all accessories easily.
Probably the other housing available as an optional accessory to some is cm longer and therefore measure the recess generous. I would nevertheless like better if z. B. beilägen foam filler in order to accommodate the smaller housing "wobble-free" can.
