Sony A9 III Underwater Housing

Sony has once again broken news of an exciting new development in the camera industry. The Sony A9 III mirrorless camera is the company's first full-frame camera with a global shutter. As a result, it provides professional photographers with the fastest-ever continuous burst shooting rate at full quality, capturing 24.6MP raw and JPEG images at a speedy 120fps.

There's no blackout during burst shooting, and the global shutter prevents the "rolling shutter" distortion that occasionally occurs with ordinary sensors by reading each pixel of the sensor simultaneously. The other exciting enhancement, is the ability to have flash sync speed's up to 1/80 000s, which isvery exciting for underwater photography.

This implies that you can shoot quickly moving subjects and camera movements, such as panning alongside cyclists, without having to worry about your images turning out distorted. There are surprisingly few compromises in this full-frame camera's record-breaking mode.

The Ikelite 200DL Sony A9 III underwater housing is made from durable polycarbonate material, making it lightweight, easy to transport and use and immune to any form of corrosion that may become an issue with aluminum housings. A secondary benefit to being made from polycarbonate rather than aluminum is that it's more affordable than some of the other underwater housings on this list. Not only is it more affordable, but it also comes with a vacuum valve out of the box, which will help budding underwater photographers save even more money. You will have to purchase the vacuum pump separately, however. The vacuum system, combined with Ikelite's new dry lock (DL) port system and a clear back, which lets you see if there are any leaks, means your camera will be safe from water damage. This 200DL version which is depth rated to 200ft. is the big brother to the Ikelite 50DL (listed below).

The Ikelite to Canon TTL converter is one of the fastest and most accurate trigger systems out there, which is why many people turn to Ikelite housings.

The Aquatica Sony A9 III underwater housing is a robust design that feels solid in hand thanks to its high-quality aluminum construction. Sea & Sea make excellent strobes, and as you'd expect, their housings are compatible with them with a TTL flash trigger. This combination of Sea & Sea housings and strobes makes for the most accurate strobe system on the market.

A large LCD screen on the back of the housing and a viewing window on top means you have an unobstructed with of your camera's setting and menu options while underwater, which is a big selling point for this housing. Another feature not found on many other housings is the glow-in-the-dark buttons to help you when diving at night or in dark waters.

The new Sony A9 III Camera is the first camera to use a global shutter image sensor, which results in zero distortion in both still and motion pictures. With its new Pre-Capture feature, you can catch the action just before the shutter releases, which is ideal for situations when the shutter timing is unexpected, such as when photographing sports or animals. Maximum frame rate for this function is 120 fps.

Possibly the biggest highlight, especially for underwater photographers, is the development of the global shutter and it's affect on flash sync speeds. Sony claims to be able to Flash sync at any shutter speed-even the maximum of 1/80,000 second. This eliminates the need of any HSS adapters or triggers. So high speed movements underwater and syncing of flash outputs should be an issue of the past.

The Autofocus capabilities of this camera are also impressive. You have 8.0 stops of 5-axis optical in-body picture stabilization. Moreover, the 759-point phase detection autofocus system of the Sony A9 III camera covers 95.6% of the scene with AF precision as low as -5.0EV. XS and XL focus area spot sizes are another new feature on the A9 Mark III.

When it comes to underwater video capabilties, the global shutter technology entirely eliminates rolling shutter and banding aberrations, which is a major gain for video. The a9 III records UHD 4K video at up to 60 frames per second by capturing and downsampling the entire 6K image area. Additionally, without cropping, it can capture in 4K at up to 120 frames per second. For optimal quality, recording 10-bit 4:2:2 internally using All-I encoding is possible. Usinge the full-size HDMI port to send a 16-bit raw output to an external recorder that is compatible. Picture profiles such as S-Log3, S-Cinetone, and others can be used to optimize the image for your production workflow.
