how good are the videos and photos shot through the pouch?
The photos and video will comes out clear. The pouch protects the camera, but the lens is actually inside a clear port.
You don't shoot through the pouch. Instead, align the camera lens with the lens port and take pictures that way. Make sure you buy the correct size because if you get a pouch too big for your camera, there will be a ring effect around your pictures due to having a lens port too big for the camera.
