Using a precise laboratory workflow, he tested dynamic range, noise, high-ISO behavior, and exposure recovery. All shots were captured remotely through the Sony Creators App to avoid vibration, exported as JPEGs, and analyzed with a Python script measuring four metrics — Structural Similarity Index (SSI), Mean Squared Error (MSE), Peak Signal-to-Noise Ratio (PSNR), and Average Pixel Value (APV).
Conclusion: Despite being the smallest and least expensive of the group, the Sony RX1R III delivered outstanding sensor performance — often ranking second overall and first for overexposure recovery. The Leica Q3 28 mm remains a benchmark for shadow and high-ISO recovery, while the Fujifilm GFX100 RF surprisingly placed last in several categories.
The Math Photographer concludes that sensor differences among modern cameras are now marginal in real-world photography — factors like workflow, ergonomics, and brand preference matter far more. Still, the Sony RX1R III earns special praise as “a proud winner despite its size.”
Sidney Diongzon would like the Sony A7V to include the following new features:
Audio-only recording mode with 32-bit float audio — allows recording just audio in-camera without video, useful for voiceovers and maintaining consistent sound without external recorders.
Larger, higher-quality 4-inch screen — similar to the Nikon ZR display, combined with Sony’s four-axis flippy-tilt mechanism, ideally OLED or using Bravia display technology for better color and brightness.
Built-in internal memory (64 GB–128 GB) — provides backup or emergency storage when SD cards are full or forgotten, and can be used for reference photos or videos.
I am 99,999% certain none of these will make it into the Sony A7V…but maybe on cameras coming in 1-2 years from now this would make sense?
UPDATE: After the Canon R6III launch he posted this:
So that’s it for now! I hope we will soon get the definitive answer about the sensor…is it new or not?
