Sony a7s III Review

The long-awaited Sony A7S III has finally been out, and boy does it not disappoint. It is the best hybrid video camera that money can buy because of significant advancements in the areas of handling and connection, a viewfinder that is razor-sharp, and, of course, very excellent low-light performance across both video and stills. It’s not only one of the most perfect video cameras but also one of the best cameras for YouTube that you can get right now.

The body of only A7S III costs $3,498 in the United States, which translates to £3,800 in the United Kingdom and $5,999 in Australia. It is a best-in-class low-light 4K video camera thanks to a long-awaited new 12.1MP back-illuminated full-frame sensor, and it also features a new Bionz XR processor that brings 8x faster performance and an expandable ISO of 40-409,600. Additionally, the specs impress with a class-leading 15 stops of dynamic range.

The A7S III features a completely articulating screen, which is one of the many other highlights of the show. This was previously only hinted at by Sony on the ZV-1, but it has now been fully implemented on an A7-series camera. The fact that Sony has finally chosen a complete touch user interface, which makes interacting with the camera much more intuitive, may be an even larger deal for Sony fans who have been dissatisfied in the past.

Sony a7s III Features

Adding a screen that can be fully articulated is one of the most significant new features introduced by the A7S II. The function was first hinted at on the Sony ZV-1, but it has now finally been implemented on an A7-series camera, and it couldn’t have arrived any sooner.

The departures from custom to our great good fortune do not end there. The fact that Sony has finally chosen to implement a complete touch user interface, which works wonderfully, is likely to be of more significance to long-time fans of the firm and reviewers.

Other impressive flourishes can be found as you work your way around the body of the camera, such as a full-sized HDMI port and a dedicated record button located on the top plate. These design and ergonomic changes are coupled with these other impressive flourishes to create a camera that is both beautiful and comfortable to use.

Sony a7s III Build Quality.

The Sony A7S III is a sturdy piece of equipment despite its relatively small size. You might be excused for missing exactly how much of a revamp this is going to be based on first impressions considering that the body structure is so identical to that of the A7S II.

To begin, one of the custom buttons above the grip has been replaced with a huge record button. This change helps establish that this camera focuses significantly on video recording. The control wheel is still located at the top of the handle, and it is joined there by a switch that turns the camera on and off, a button labeled C2, and dials for setting the mode and exposure (both of which can be locked).

Even though the A7S III does not have an official weather-sealing certification, Sony has informed us that it can withstand light rain. The ports are protected by rubberized coverings and are located on the left side of the camera when it is held with the lens facing the front.

These connections include a full-sized HDMI connector, which is a huge advantage for videographers. Additionally, there is a USB-C port and a micro USB port (it’s an unusual move on Sony’s part to have all of these), in addition to a headphone jack and a 3.5mm microphone jack. You have the option of purchasing a Sony XLR-K3M hot-shoe accessory if you are yearning for XLR audio-in. This device allows for up to four audio inputs. Memory card slots and an NFC point may be found on the right-hand side of the device.

Sony a7s III Performance

When you first start using the Sony A7S III, one of the things that will stand out to you is how well it works in dim lighting. Increasing the ISO is not a challenging experience; in fact, it is pretty rewarding because the camera can handle high sensitivity in a manner that is mind-bogglingly excellent.

The low-light capabilities of the A7S III make perfect sense. Sony has developed a completely new 12.1-megapixel sensor that features enormous pixels that are dispersed throughout the full-frame, 35mm surface area. On paper, these specifications aren’t new. Still, with double, the readout rates of the A7S II’s sensor, a back-illuminated structure that can consume more light, and a new Bionz XR processor powering things along, the improvement in low-light performance shouldn’t come as a surprise.

Sony a7s III Video & Image Quality

Moving on to the image quality, we put the Sony camera through a head-to-head competition with a Blackmagic Pocket Cinema Camera 4K by shooting at ISO 16,000, f/2.8, and 25 frames per second in 4K resolution. The Blackmagic looks to have exposed the scene a little better than the A7S III, but there is no debate on how well the A7S III handles noise; it is the apparent winner.

If you are unfamiliar with the Pocket Cinema Camera 4K, its low-light handling is well acclaimed because of its dual-native ISO. Additionally, it comes with an inexpensive price tag, costing less than a third of what the A7S III does.

That being said, the A7S III is head and shoulders above the Pocket Cinema Camera, capturing practically no discernible picture noise even though the film was shot in the dead of night. In contrast, the Pocket Cinema Camera records granular material that is entirely worthless.

Sony a7s III Final Verdict

Sony has not simply upgraded one or two parts of its A7S series; rather, with the new A7S III, it has made a set of enhancements that cover every area of the camera, resulting in a device that is superior to other cameras in its category. It handles video playback well because of its articulating screen and touches the display. Additionally, it features a full-sized HDMI connector and outstanding IBIS, which are at the top of the list of additional bonuses. It is quite a little more expensive than the A7S II was when it first came out, but if you are a filmmaker who needs large physical pixels and outstanding performance in low light, this is the best option now available.

Sony a7s III Pros & Cons

  • New User Interface for Touch
  • Touchscreen that is fully articulating
  • There are no problems with overheating
