Sony RX1R III Review (2025): The Full-Frame Compact We’ve Been Waiting For?

After nearly a decade of silence, Sony has finally revived its premium full-frame compact line. The Sony RX1R III is here — and it promises the perfect mix of portability, performance, and pixel power. But does it live up to the hype?
Let’s dive into the specs, real-world performance, and whether it’s worth your investment in 2025.

Overview: What Is the Sony RX1R III?
The RX1R III is a 61-megapixel full-frame camera with a fixed 35mm f/2 Zeiss Sonnar T* lens.
It’s designed for photographers who crave DSLR-level image quality in a pocket-sized body.

What’s New in the RX1R III
Sony didn’t just update the sensor — the entire core of the camera has evolved.
Here’s what’s fresh:
AI Autofocus from the A7R V: Eye/Face/Animal/Vehicle tracking

Touchscreen controls for modern usability

Built-in EVF (no more pop-up design)

Larger battery for better endurance

New “Creative Look” profiles for film-like color grading

The only thing not new is the lens design, which is the same trusted 35mm f/2 from the RX1R II — sharp in the center, but with some softness at the edges.
