Sony RX100 VA (RX100M5A) Announced

Sony makes updates to the original RX100 V with their new RX100 VA model
By Bryan Chu

Sony recently announced they are updating the RX100 V camera with a new version called the RX100 VA, which has some impressive upgrades including a new processor. This is not a replacement or upgrade to the RX100 VI, but rather a unique hybrid of the popular RX100 V combined with the new processor, promising the best of both worlds for underwater shooters. It replaces the RX100 V which is no longer available.

Upgrades from the RX100 V

  • Image processor updated, which will make an improvement to image quality
  • Shooting in 24 fps burst mode with full AF/AE (auto-focus/auto-exposure), the buffer size has been increased from 150 jpegs to 233 (50% improvement)
  • "My Menu" functionality allowing you to register menu items for instant recall and customize menus. You can also make button assignments for up to 30 functions to retool the camera interface for your shooting preferences.
  • "Zone" added as an option for autofocus area
  • Display lag time in EVF (electronic viewfinder) reduced
  • Proxy movie mode (captures 720p footage alongside 4K capture)
  • Custom button can now control one of 62 camera functions, instead of the previous 44
  • High precision eye autofocus feature (improvement over original)
  • A number of other functionality improvements

Implications for Underwater Photography

The updated image processor, with a potential for improvements to image quality, is of course a nice thing to have. It also means that file storage underwater could be more seamless with less lagtime. 

As far as the burst mode buffer upgrade, unless you tend to shoot fast action in ambient light conditions or with video lights, and run out of buffer with the 150-image size, this change will not affect your underwater photography. It could be useful for topside photography, although 150 images at 24 fps already gives you 6 seconds of continuous burst shooting. But there may be some situations where the extra 3 seconds of continuous burst shooting could help you get the shot you want. And although the reduction in EVF display lag time is nice to have on land, that won't affect underwater shooting as the EVF can't be used underwater.

The changes to menu functionality is another upgrade that is significant for underwater photographers. The ability to customize button assignments should help avoid having to cycle through menus when you have to change settings quickly to adjust for new shots or changing conditions. This will allow for a better shooting experience underwater.

Overall, this update looks more like a firmware update than anything else, and with the exception of the customizable button functionality is not expected to have a noticeable effect on underwater photography functionality. If you are looking to buy an RX100V, this will be the new version available, and there's no reason not to get it. But there might not be much reason to think about upgrading from an existing RX100V - if the advantage of a long lens sounds interesting, it would be better to go for the new Sony RX100 VI.

RX100 VA Underwater Housings

Since the RX100 VA is the same size as the RX100 V, it will work in the same housings as the RX100 V.

Bryan is an associate editor for the Underwater Photography Guide. He loves any activity that takes him out into nature, and is especially fond of multi-day hiking trips, road trips to National Parks, and diving. Any kind of diving. He discovered the joy of underwater photography on a Bluewater trip to the Sea of Cortez, and after "trial and erroring" his way to some level of proficiency, has been hooked ever since. He has not done nearly as much diving as he would like, but has so far taken underwater photos in a diverse range of places, including BC, the Sea of Cortez, Greenland/Iceland, Northern Norway, the Galapagos and French Polynesia.

After working as a chemical engineer at a major oil & gas corporation for 9 years, Bryan finally had enough (and it didn't help that he was living in landlocked Edmonton, Canada with frigid winter temperatures and no real diving to speak of). He and his girlfriend decided to pack up their things and travel the world; they started their journey mid-2018 and will visit a number of great dive locations along the way. He is very excited to expand his underwater photography experience and skills while experiencing new cultures and exciting parts of the world. Though he is also a bit worried about the following equation that has so far defined his dive travels: Corporate job ($$) = Dive travel ($) + Underwater Photography ($). Taking away the left side of that equation seems like it might put things a bit out of balance. But as he reasons, what's the point in life if you can't take some big risks and have some fun along the way?
