Sony a7S IV: Trustworthy Specs ?

Is the Sony A7 S4 coming in 2024?

What can we expect from the successor to the A7 S3? Will it do 8K, have a global shutter sensor, or a new thermal architecture? How trustworthy are the specs that are floating around?

But before we get to the details, please Subscribe to this channel. It doesn’t cost you anything, helps this channel grow, and keeps you up to date on the latest camera coverage.

The bad news first – none of the rumors that have been floating around have been validated or come from known and trusted sources. But that doesn’t mean we can’t glean a theme from the specifications that have been floating around. The A7 S3 is definitely going to have an increased resolution, oversampled video, and an improved thermal architecture. But beyond that, we have to take a journey into the world of unvalidated and untrusted sources for a set of detailed specifications.

The Sensor

It is supposed to have a 19-megapixel full-frame stacked dual-layer sensor or a 40-megapixel sensor. I’m leaning towards it being a 19-megapixel full-frame stacked dual-layer sensor. What’s different about a dual-layer stacked sensor is that it separates the photodiodes and the pixel transistors on different substrate layers. This architecture doubles the saturation signal level, widens the dynamic range, and reduces noise. The A7 S4’s sensor will play a crucial role in delivering exceptional low-light performance, which is essential for video-centric cameras like this.

Video Modes

With the sensor rumored to be 19 megapixels, the A7 S4 will likely not support 8K video. However, it will offer impressive 6K video recording at frame rates of 24, 25, and 30 fps. It will also support high-resolution slow-motion recording at frame rates of 100 and 120 fps in 6K. In addition, 4K recording will be available at various frame rates ranging from 24 to 120 fps. The oversampled 4K video on the A7 S4 is expected to deliver outstanding detail and clarity, similar to the Canon R5.

While the A7 S4 may not push the boundaries in terms of resolution and frame rates, its focus on detail and performance in low-light conditions is paramount for its target audience.

Dual Base ISO

The A7 S4 is rumored to feature dual base ISO, with a second base starting at 25,600. This specification seems quite high for a second base ISO, leading to some skepticism regarding its validity. However, if true, it would be interesting to see how Sony has implemented this feature in the camera’s architecture.

Anti-Aliasing Filter

One notable aspect of the A7 S4 is its absence of an anti-aliasing filter. This decision could have significant implications for image quality, particularly in terms of detail and sharpness. It remains to be seen how Sony has addressed potential issues related to moiré and aliasing without the presence of an anti-aliasing filter.

Thermal Architecture

The A7 S4 is expected to feature a new thermal architecture, designed to enhance the camera’s performance in varying temperature conditions. The A7 S3 already demonstrated impressive thermal performance in hot climates, so the A7 S4’s new thermal design will likely build upon this foundation.


According to the latest specifications, the Sony A7 S4 is projected to cost between $3,499 and $3,999. Sony’s pricing strategy for their previous models suggests that the A7 S4 will be positioned as a premium offering in the mirrorless camera market. With Sony’s strong presence in the industry, it is reasonable to expect the A7 S4 to be competitively priced against its closest competitors.

In conclusion, while the specifications for the Sony A7 S4 are based on unverified sources, they present an intriguing glimpse into the potential features of this highly anticipated camera. The A7 S4’s focus on low-light performance, video capabilities, and innovative sensor technology make it a promising prospect for videographers and content creators looking to elevate their craft.
