The highlight of the RX100 VI over the RX100 VA is its unprecedented macro capability. The zoom on the 24-200 mm f/2.8-4.5 zoom lens cannot be beaten by other compact underwater setups. Details captured with this lens are remarkable. When combined with a wet macro lens (diopter), the realm of super macro photography is attainable. The tiniest details of the smallest subjects can be captured with this set up (once you get a little practice in of course).

The RX100 VA introduced an increased image buffer, burst shooting up to 24fps, and customizable menus. This is excellent for photographers seeking to capture quick pelagic animals that need good burst speed and more processing power. The RX100 VA still carries all of the advantages of the RX100 V including the 315 point phase detection autofocus system and the 20 MP/1" Exmor RS BSI CMOS sensor. The main advantage of the RX100 VA over the VI is that the RX100 VA is able to shoot with both macro and wide-angle wet lenses on the same dive. This is because the lens is shorter and has less zoom capability than the RX100 VI. You also don't need to purchase additional ports/adapters for dedicated wide angle and macro set ups.


The Sony RX 100 III is one of the most popular options for underwater photographers looking for the balance between image quality, price, size and ease of use. It’s a step up from the RX 100 II. This model has a better video bit-rate and adds an electric viewfinder. The RX 100 focuses faster that most other compact cameras. It’s a great option for pro photos without the weight and bulk of a dSLR camera.

The Canon 1DX Mark II has been a staple DSLR camera for professional video since its release in early 2016. It comes equipped with a 20MP, 35mm Full Frame Canon CMOS sensor and records 4K video at 60fps or Full HD video at 120fps. Very few full-frame cameras can record video at these high frame rates and a high bit-rate, which can then be slowed down for slow-motion video.

The Sony A7 series has led the charge in full frame mirrorless cameras and the A7 III and A7R III have been some of the most popular cameras on the market since their release in April 2018. Similar to the Nikon Z6 and the Panasonic S1, the Sony A7 III has fewer, larger pixels compared to the A7R III and therefore, a more favorable for video use due to the resulting low light capabilities. The A7 III tops out at 4K 30p and records internal 4:2:2 8-bit video. You also have the ability to shoot on various picture profiles like HLG & S-Log3 Gammas, which offer less-compressed video capture and facilitate maximum color rendition and dynamic range for post-production flexibility. It also has impressive autofocus capabilities with a 693-point hybrid autofocus system.
Before you start digging into the reviews, a few notes on choosing a cam that's right for you. You'll definitely want to consider frame rate, expressed as frames per second (fps). Some action cameras offer up to 240fps recording, while others only go to 30fps. For standard playback, 30fps is perfectly fine. It's when you want to slow footage down in editing to create dramatic scenes that frame rate matters. Footage captured at 240fps can be slowed down and played back smoothly at one-quarter speed. You may also want to go for a cinematic look, in which case you'll want one that has a 24fps capture option, the same speed used by most Hollywood productions.
