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.”
SAR readers (Thanks!) spotted a massive $400 discount on the Sigma 24–70mm ART II lens on Amazon. However, note that it’s being sold by a third-party seller — so proceed with caution, as I can’t vouch for their reliability.
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?
