Sony RX100 VI Features

Enhanced Optical Zoom

The key upgrade of the Sony RX100 VI is the new 24-200 mm f/2.8 – 4.5 lens. This has been upgraded from a 24-70mm f/1.8-2.8 lens on the previous RX100 V. The zoom and optical quality of this new lens has the capability of producing stunning, detailed macro and super-macro images – especially when paired with a wet lens. However, it comes with its challenges. When zoomed out, the lens extends relatively far – requiring a long port. A long port makes it impossible to add desirable wide-angle accessories such as wide-angle wet lenses. This being said, some housing manufacturers are coming out with multiple port options that can accommodate for both wide-angle and macro shooting by switching ports between dives.

Improved Autofocus

Autofocus speeds have increased to 0.03 second autofocus from 0.05 sec. The RX100 VI also comes with 315-point phase-detection AF points. These autofocus improvements are a huge help to anyone looking to take the RX100 VI to the full extent of its super-macro capability. Good autofocus is imperative for capturing super-macro images where even the slightest movement can drastically change the composition of the shot.

High Resolution Video

The Sony RX 100 VI is also proving to be a supermacro powerhouse in the video world. Consistent with Sony’s commitment to improving its video capability in multiple camera lines, the RX100 VI has been upgraded to be able to shoot 4K movies with full pixel readout and no pixel binning. It can also shoot 4K HDR. This video capability is a milestone for video in compact camera set ups as it is ideal for shooting macro and super-macro video. Keep in mind shooting 4K will require an SDXC card.


The Sony RX100 VI’s burst shooting can capture 24 frames per second with continuous autofocus and a buffer of about 100 shots. This capability places the RX100 VI among the fastest compact cameras on the market. Therefore, the RX100 VI is also an ideal camera for quick-action underwater photographers – specifically those shooting waves or quick pelagic animals.

Best Lenses with the Sony RX100 VI

As mentioned, due to the extension of the lens when fully zoomed, different ports are necessary when shooting with macro or wide angle wet lenses and the RX100 VI. This means that the type of wet lens used will need be chosen prior to diving and limits the diver to shooting either macro or wide-angle during a dive – not both.


Macro wet lenses allow you to get even closer and more detailed photos than the already capable 200 mm zoom on the RX100 VI. A strong diopter such as the Nauticam Super Macro Converter or the Kraken KRL-03 +12 can be a great way to open up the realm of super macro photography. Going for something with a little less magnification such as the Bluewater +7 is an easier option for beginner macro photographers.

Bluewater +7 Macro Lens - The Bluewater +7 is a high-quality two-element macro lens made of optical glass. It is UV-coated and anti-reflective. It offers a much cheaper price point than the Nauticam lenses, although it also offers slightly less magnification. Slightly less magnification is great if you are just starting out in the world of macro photography. The zoom capability of the RX100 VI is very good, so this can be all that you need to take beautiful macro photos. Bluewater +7

Nauticam Compact Macro Converters (CMC-1 & CMC-2) - Both Nauticam CMC lenses offer amazing sharpness, with varying strengths of magnification. 4.5 & 2.8 average magnification respectively, it's great to have both within your quiver of lenses for maximum versatility while diving and shooting macro. Nauticam CMC-2 or Nauticam CMC-1. These are the highest quality macro lenses for taking supermacro images with the RX100 VI.

Wide Angle

Without a wide angle wet lens, compact cameras tend to struggle in the area of wide angle underwater photography. A wide angle wet lens allows the photographer to take photos with a wider field of view and get closer for more color and detail in the image.

Fantasea UWL-09 Wide Angle Lens - This wide-angle option provides a great 130-degree Field of View, allowing you to switch over to wide angle for reefscapes, large animals coming in close, etc. Image results are sharp from corner to corner with minimal abberations. In addition, the lens will focus through out the zoom range of your camera.  Fantasea UWL-09

Kraken Sports KRL-01 - The KRL-01 was designed to work with a variety of cameras at 24mm focal length, and features full zoom through capability. It has a multi-layer BBAR coating for anti-reflection and improved optical clarity. It is even compatible with micro 4/3 and full frame cameras, providing a great choice for anyone who may upgrade in the future. The KRL-01 offers a whopping 145-degree filed of view!  Kraken KRL-01

Underwater Housing Options

There are six great underwater housing options to choose from for the Sony RX100 VI. There are two things important to note with the Sony RX100 VI.

1. It is not compatiable with any other RX100 type housings. 

2. Due to the extreme zoom capability, it is necessary to have a seperate port for macro and wide angle photos if you want to use the full extent of the zoom capability. This means you can only take one type of photos during a dive. 

Each of the housings above will offer control of all primary camera functions and provide a secure enclosure for use underwater. Some housings are higher quality, and offer a variety of added accessories, while others stick to the basics and allow users to enjoy a no frills, straightforward diving experience.

Choose Fantasea, Recsea CW or Ikelite if your focus is on the dive and photos are just for fun. In addition either of these options are great for those on a budget. If you really like to tinker with your photos or settings, a higher end aluminum housing, such as Nauticam or Recsea Aluminum is recommended. All housings feature fiber optic ports for attaching strobes, and the ability to add a tray with handles for a more professional feel.

The Nauticam housing goes one step further with a unique port system allowing you to swap the front port for a more dedicated shooting set up.

Underwater Settings for the Sony RX100 VI

Check that these key function are set on your camera menu before diving with the Sony RX100 VI:

  • The most important menu setting is to make sure the AF Illuminator is turned off, otherwise your camera will have trouble focusing once inside the underwater housing.
  • Select Raw & JPEG so that you can easily share JPEGs but also edit RAW files more effectively
  • Select AVCHD for video file setting
  • Set creative style to vivid if you want more reds to come out underwater in your JPEG or neutral if you will be editing all your files
  • Turn on Auto Review if you want to view each photo immediately after capturing it. The suggested time is 2 seconds.
  • Flash mode: fill flash, flash compensation to 0.0
  • Red Eye Reduction: off

Memory Recall Function: Due to the RX100 VI's amazing zoom capability, when in a housing in a standard port, the lens can actually hit the port glass when zoomed in all the way. Using the memory recall function you can set the camera so that it "remembers" specific zoom levels and does not hit the port. This will allow you to easily switch between wide angle and macro on a standard port. In order to use memory recall, put your camera in manual mode. Then zoom in with the camera in the housing, so that the lens does not hit the port glass, but enough to take a macro photo. Go into the menu and go to panel 9 under the camera icon. Click memory and then click a number (at the top of the memory panel) to save your settings. When you need to access your setting in memory recall, switch the dial at the top to MR and your settings will show up. You can set individual settings for shooting wide angle, macro, and mid-range photos as you can save three different memory recall settings. 

Shooting Macro:

Remember that apterture controls your depth of field, choosing a larger number aperture will mean more of the image will be in focus. For starting settings on the RX100 VI we recommend at least F8. In addition we always recommend using a focus light when shooting macro in order to help your camera lock focus more quickly and accurately.

Best Macro Settings with a strobe (no wet lens):

  • Manual Mode
  • Auto White Balance
  • F8
  • 1/500s
  • ISO 80

Make sure you are zoomed out all the way for best focusing and image quality. If using a strobe, Auto White Balance delivers accurate color balance - just remember to set the internal flash to forced flash mode and your strobe to TTL (or manual if you're comfortable with more adjustments).

Remember that shooting at an aperture of F8 will allow for much of the subject to be in focus. You can also experiment with opening the aperture down to F2.8 for a shallow depth of field.

Best Super Macro Settings with a strobe (using a wet lens):

When shooting with a macro diopter, you will want to zoom in to create as much magnification as possible of the subject. Because of the increased magnification, stop down the aperture to create more depth of field. Our recommended starting settings are:

  • Manual Mode
  • Auto White Balance
  • F11
  • 1/500s
  • ISO 80 

Shooting Wide Angle

Remember that shutter speed controls the amount of ambient light in the photograph. The faster the shutter speed, the less light in the background. This is important primarily when shooting wide angle with a strobe. Zoom the camera all the way out and get closer to your subject for best lighting. Shooting with a wet wide lens* allows you to get a wider field of view while being very close to your subject and is recommended for the best wide angle shots.

Best Wide Angle Starting Settings, with a Strobe:

  • Manual Mode
  • Auto White Balance
  • F6.3
  • 1/125s
  • ISO 80
  • Camera on Forced Flash (not auto or it may not flash!)
  • Strobe on TTL (auto controls) or Manual with Preflash (adjust power as needed)

*Some wet wide lenses may vignette on the RX100 VI (dark corners), if this is the case zoom in as little as possible until the vignetting is gone.

Use strobe power to control the light on your subject, adjust shutter speed to control the light in the background.

Shooting Wide Angle with Ambient Light:

  • Adjust your aperture and shutter speed from the settings above to properly expose the foreground (ie: let in more light).
  • Shoot with the sun behind you for better colors and less shadows.

For shooting creative wide-angle photography such as a sunburst or silhouette, stop down the aperture to F11 and/or increase your shutter speed to 1/1000s or faster. This will decrease the light entering the camera and help freeze the water to capture stunning sun rays.
