I have been wanting to try the Q7 camera underwater, and I managed to find an Ikelite housing that was large enough to fit the Q7 inside.
I had to make a few modifications to both the housing and the camera, but overall this works out quite well.
The camera takes nice photographs underwater, and it is responsive enough in my opinion.
