The Canon G7X III is an amazing camera to use underwater. It’s a great system to grow with and with additional accessories is capable of nearly anything.

All housings available are good choices. The Fantasea housings have been our top sellers for years and provide the best value for this camera. They also provide better ergonomics than the Ikelite and have the vacuum system built in for a lower price than just the Ikelite housing. Fantasea also allows access to pop up the flash underwater, whereas with Ikelite you have to remember to pop it up before closing the housing.

Ikelite has the advantage of switching to a dome port instead of the standard flat port, and benefitting from a wider field of view without fussing around with wet lenses. It’s also better for split shots, rather than using a wet lens.

If you prefer to get the best – Nauticam is the way to go. Better quality materials, excellent ergonomics, interchangeable ports, vacuum system available, access to pop up the flash and more. The catch is of course the price – more than double the Ikelite / Fantasea housings. If it’s within your budget, you’re going to love it. However, if your budget is limited and it’s either getting the Nauticam housing alone, or getting a polycarbonate housing + strobe, we would recommend getting a strobe which would improve your photos far more than the type of housing you use.
