Panasonic is well established brand in the video realm and their reputation definitely precedes this product. They included a fast working DFD feature that calculated the focus distance to help prevent your video from being blurry or out of focus. If you want a simple, compact camera that will render high-quality underwater video, the Panasonic Lumix LX10 is a great camera for you.
When combined with a wet macro lens (diopter), super macro photography is within reach. The tiniest details of the smallest subjects can be captured with this set up (once you get a little practice in of course). With the RX100 VI we recommend using the Bluewater +7 if you are just getting the hang of macro and super macro photography. The Nauticam Compact Macro Converters (CMC-1 & CMC-2) are top of the line wet lenses with amazing lens sharpness but have a lot of magnification and can be a little more difficult to use.
Like I mentioned, underwater housings can cost more than the camera itself so choosing the right one is an extremely important decision. They do more than just keeping your camera dry. They also protect it from pressure, allow you to use the camera controls, enable the use of different lens ports and hold accessories like lighting. Be sure to invest wisely on this one!
