UNDERWATER CAMERA EQUIPMENT BUYING GUIDE - VIDEOCAMERAS
There are different cameras aimed at video, such as GoPros, system cameras, and cinema cameras. GoPros are designed for simple use with a wide angle, capturing underwater footage. System and cinema cameras are focused on professional use.
We are seeing a significant rise in system cameras. Consider the Sony A7SIII, Panasonic GH6, and Canon R5C— top models that are excellent for filming. Typically, filming is done in a "flat profile" so that color grading can be done effectively afterward.
For video, video lights are, of course, used, with or without ambient filters.
Despite the autofocus improving, we still recommend manually focusing during filming whenever possible. Nauticam and GATES housings support this, while Ikelite usually does not. Having control over the focus often results in a steadier image, as the "searching" of the autofocus is not visible.
For video, there are several accessories that are used, such as a monitor, SDI surface cable, video lights, red filters, and ambient filters, for example.
Ambient filters are filters that you attach to your video lights. You use ambient filters when you manually set the white balance to match the environment and want an overall accurate color. If you set the white balance to the environment without filters on the lights, the light from the lamps will appear red. See the example below (right without filters on the lights, left with).


If you want to start filming, there are also compact cameras and APS-C cameras that are well-suited for this purpose. Consider the Sony RX100VA, Canon G7X III, Sony A6700, etc.
If you're willing to spend a bit more for a more advanced camera, think of the Canon R7, Sony A7IV, or Panasonic GH5.
For advanced filmmakers, options include the Sony A7S III, Panasonic GH6, and Canon R5C.
