Features To Look For In A Compact Camera:

As you may know from reading the Underwater Photography Guide, it is important to select a compact camera that offers full manual controls, the ability to shoot in RAW, HD video, and the ability to accept wide-angle lenses like a fisheye lens. Fortunately we are now blessed with several cameras and great housings that meet these criteria. 

Compact Camera Improvements:

There have been many improvements in the compact camera lines over the past few years. Larger sensors, faster focusing and more controls have all led to a selection of cameras that work smoothly, keep size tiny and are functional with a variety of lenses and accessories to round out your underwater photography experience.

Take a look at our top picks for 2018 below.


Sony RX100 Mark V or IV

Excellent for video shooting & ambient light shooting.

Read our complete Sony RX100 IV Review.

The bright F1.8 lens of the Sony RX-100 IV & V cameras make both of them an exceptional choice for video and ambient light shots. You can also get great wide-angle photos with the RX-100 IV/V with the UWL-09 super-wide lens ,the Kraken KRL-01, or the Nauticam WWL wet wide-angle lens. Both cameras feature a large 1" sensor with 20 MP resolution which provides excellent image quality, fast autofocus, useful video modes (like slow motion) and full manual controls.

The RX100 V offers an improved autofocus system, a 24 fps burst mode (vs 16 fps on RX100 IV), and additional recording settings for video. It does, however, have a slighly lower battery life than the IV.

Sony RX100 Mark V and IV Underwater Housing Options:

Many of the housings from the RX100 IV will work with the RX100 V, however the manufacturers also released new housings with slight improvments. Some of these housings are backwards compatible with the RX100 IV as well. Check out the list below:

Nauticam Housings - high quality aluminum, great ergonomics, vacuum electronics included, and a variety of Nauticam accessories to round out your system.

Recsea Housings - both high quality aluminum and budget friendly polycarbonate options availble. Well designed, simple to use, full camera controls accessible in the aluminum housing, ready to accept a varitey of wet lenses.

Sony RX100 Mark III

Excellent Image & Video Quality

If the amazing slow-motion video, fast shooting and fast shutter speeds of the RX100 IV / V are not important to you, the RX100 III is a good choice. The RX-100 III changed the lens from a 28-100mm lens, to a brighter 24-70mm lens. Although better for video, fish, and indoor photography, this change is not as good for macro shooters, but great results can still be gained when using high quality diopters such as the Bluewater +7, Nauticam CMC ,Subsee +10, or Kraken KRL-03.

Choose the RX100 III over the IV or V if you don't need all the fancy shooting and video modes, such as slow motion or high burst shooting. The camera is a few years older, but still produces excellent images and will save you some money overall compared to the newer Sony options.

Canon G7X Mark II

Read the Canon G7X Mark II Review

The Canon G7X II is a tiny camera with a large 1-inch sensor, a direct competitor to the Sony RX100 series cameras. It is an excellent fast-focusing camera with great image quality, and has better macro capability than the Sony RX-100 III / IV / V thanks to Canon's dedicated macro focus mode. Macro magnification is almost as good as the Canon G16.

The Canon G7X Mark II boasts improved auto-focus capability and battery life over the G7X, a new time lapse mode, and also signicantly improved high-speed continuous shooting speeds.

Canon G7X Mark II Underwater Housing Options:

We recommend the Recsea or Nauticam Housings for best controls.

Olympus TG-5


For an excellent camera option both in and out of the housing, the Olympus TG-5 cannot be beat. The camera is waterproof to 50 feet (15 meters) by itself, making it an excellent option for the casual shooter who wants a camera that can go anywhere.

Pair it with the Olympus PT-058 housing for a compact powerhouse at an insanely low price. The TG-5 has a high speed 12 MP sensor designed for excellent low light performance and noise reduction. It shoots 4k video and RAW photos and includes built in WIFI, making transferring photos on the go a breeze.

Pros - compact size, great macro capability for still subjects using microscope mode and support for beautiful wide-angle images when used with the Kraken KRL-02 or UWL-04 fisheye lens.

Cons -  lacks a full manual mode - aperture priority mode will have to do. Because of these limitations, if you can afford the next step up - e.g. Fantasea G7X II - you should do it.

Olympus TG-5 Underwater Housing Options:

Best budget choice when partnered with Olympus PT-058 Housing

Best option for Tech / Wreck Divers:

The Recsea Olympus TG-5 Housing is very small, made of aluminum and rated to 100 meters depth. We highly recommend this housing for more serious use at depth.
