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).
There are some cameras that were made specifically for being used underwater for example the SeaLife DC1400. But, just from reading the mixed bag of customer reviews on Amazon, it’s clear that it’s not the best underwater camera for scuba diving. The buttons stick, the flash doesn’t work, the shutter delay is insanely slow… just a few of the problems you can run into.
Can we take photos in action camera?
The Nikon Z6 is the Nikon equivalent of the Panasonic S1 -- Nikon’s lower-megapixel version of their Z Series full frame mirrorless cameras. The Nikon Z6 offers a 24MP, full frame sensor with fewer, larger pixels than the Z7 making it a more favorable choice for video due to the low light advantages. One benefit of the Nikon Z7, as compared to the Panasonic S1, is its size. The Z7 is small and compact -- a major reason why people are turning from DSLR cameras to mirrorless cameras. The Nikon Z7 has phenomenal autofocus capabilities with 273-point hybrid phase-detection contrast autofocus technology. It tops out at 4K 30p but can natively output 10-bit 4:2:2 over HDMI in the new N-log color profile, promising greater dynamic range and flexibility in post. Beyond that, with its new firmware, it will become the first hybrid camera to offer RAW video output when coupled with the Ninja V monitor/recorder.
The Canon G7X III is a tiny camera with a large 1-inch, 20 MP sensor, a direct competitor to the Sony RX100 series cameras. It is an excellent, fast-focusing camera with great image quality and has dedicated macro focus. The camera also boasts 4K video, slow motion video, a bigger image buffer, a new stacked sensor, a better image processor, and quicker burst shooting over the G7X II.
Fortunately, we are now blessed with several cameras and great underwater housings that meet these criteria for the "best underwater camera". Whether you are looking for the best underwater camera for scuba diving or snorkeling, we are sure you will find it here. I'd also like to point out, that we define a compact camera as a camera with a fixed lens.
