In his latest video, The Math Photographer ran a detailed sensor comparison between four premium compact cameras: the Sony RX1R III, the Leica Q3 28 mm, the Leica Q3 43 mm, and the Fujifilm GFX100 RF.

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).

Results by category:

Underexposure ranking:

• 1. Leica Q3 28 mm
• 2. Sony RX1R III
• 3. Fujifilm GFX100 RF
• 4. Leica Q3 43 mm

Overexposure ranking:

• 1. Sony RX1R III
• 2. Leica Q3 43 mm
• 3. Fujifilm GFX100 RF
• 4. Leica Q3 28 mm

High ISO ranking:

• 1. Leica Q3 28 mm
• 2. Sony RX1R III
• 3. Leica Q3 43 mm
• 4. Fujifilm GFX100 RF

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.”

Camera Intelligence Launches Caira, the World’s First AI-Native Mirrorless Camera with Onboard Generative AI, on Kickstarter (Click here). This is NOT an E-mount camera abut a curious project that might give us a glimpse into the future of photography?

DxO has released major updates for three of its products — and the best part is, you can now get 15% off with our exclusive checkout code “Rumors15”!

DxO PureRAW 5.5 -> 15% off with our code “Rumors15”

• The third generation of DxO’s pioneering technology, DeepPRIME 3, delivers unprecedented image quality — free of noise and with exceptional color rendering — for images captured at high ISO levels.
• DeepPRIME XD technology is designed for the most demanding files captured in challenging conditions. It not only removes noise but also extracts outstanding detail from RAW files. Introduced in DxO PureRAW 5, DeepPRIME XD3 for X-Trans brings DxO’s most advanced denoising to Fujifilm users.
• Exclusive to DxO software and backed by over 20 years of research, DxO Modules automatically optimize lens sharpness and correct distortion, vignetting, and chromatic aberration for more than 100,000 camera and lens combinations.
• New in DxO PureRAW 5.5, integration with Photoshop’s Smart Filters gives users complete control, allowing them to revisit DxO PureRAW settings at any time.

DxO PhotoLab 9.2 -> 15% off with our code “Rumors15”

• Re-organizable masks with improved labelling — With this update, users gain even greater control over their local adjustments. Masks and sub-masks can now be freely reordered, making it easier to keep complex edits organized and intuitive. When a mask is duplicated, the software automatically labels the new version with a sequential number, saving time and avoiding confusion. These refinements streamline workflows and help photographers stay focused on the creative process.
• New PhotoLibrary filters — File management and image curation become even more efficient in DxO PhotoLab 9.2 thanks to three new filters designed to speed up how photographers locate their work. Alongside existing options, users can now instantly display only Unedited Images, quickly isolate Edited Images, or focus specifically on Edited Images featuring Local corrections. These filters simplify navigation and editing across large photo libraries.
• Improved History panel for Windows — Already available on macOS, the History panel now remembers every step of an edit even after the software is closed and reopened. Windows users can step back to any point in their workflow across multiple sessions, ensuring complete editing continuity.

Nik Collection 8 -> 15% off with our code “Rumors15”

• 30 authentic paper surfaces — Inspired by traditional photographic, artistic, and antique papers, the new textures add grain, depth, and character to images.
• Fine control — Adjust intensity, blend modes, and tonal integration to achieve everything from subtle mood to striking artistic impact.
• Effortless workflow — Nik Collection 8 integrates seamlessly with Adobe Photoshop and works efficiently alongside DxO PhotoLab, Adobe Lightroom Classic, and Affinity Photo.

From minute 39 Sigma CEO Yamaki joined the podcast. Here are a couple of highlights:

• He doesn’t work with other manufacturers, they prefer to produce lenses in their own factory
• Sigma made no profit in past fiscal year due the increase of cost.
• Response of the market on the Sigma BF was way beyond his expectations
• Sigma 14mm f/1.4 lens is a niche lens only being produced in January and February
• Demand for L-mount lenses continuous to increase

There are no secrets left — the launch is set to happen on November 6!
