Sony RX1R III Arrives with 61MP Sensor and AI Autofocus: A Big Upgrade in a Small Body
After nearly ten years of silence, Sony has returned to the compact full-frame game with the all-new Sony RX1R III. This high-end fixed-lens camera takes everything people loved about the RX1R II and turns it up a notch — or several. If you’re a street photographer, a traveler, or someone who just wants pro-level image quality in a small package, the RX1R III might be what you’ve been waiting for.
Let’s break down what’s new, how it stacks up against the competition, and whether this $5,099.99 camera is worth it.
🔍 1. What’s New in the Sony RX1R III?
📸 61MP Full-Frame Sensor
The biggest headline feature is the jump from 42.4 megapixels (in the RX1R II) to a stunning 61MP full-frame Exmor R sensor. This is the same sensor found in Sony’s flagship A7R V, allowing for ultra-detailed photos even in challenging lighting.
🤖 New Image Processors
The RX1R III is powered by the Bionz XR and Sony’s AI Processing Unit, boosting performance in autofocus, tracking, and even color rendering. This means the camera can intelligently follow a person’s body, head, or even their eyes — even if they look away or are partially blocked.
🔍 Step Crop Shooting: 35mm, 50mm, 70mm
Even though the RX1R III still features a fixed Zeiss Sonnar T 35mm F2 lens*, it now includes Step Crop Shooting, which allows you to crop in to mimic 50mm and 70mm focal lengths. It’s not quite the same as optical zoom, but for many users, it’s a welcome flexibility.
🎥 2. Video & Shooting Performance
🎬 4K at 30 FPS
Sony has finally added 4K video at 30 fps to this series — something missing from the RX1R II, which only supported up to 1080p. The RX1R III also records 1080p at up to 120 fps for smooth slow-motion playback.
🎨 Creative Looks and S-Cinetone
You also get 12 Creative Look profiles, perfect for customizing your style on the go. Plus, S-Cinetone (borrowed from Sony’s cinema line) gives your video a more cinematic feel straight out of camera — no editing needed.
🖼️ 5 FPS Burst Rate
Compared to other full-frame cameras, the 5 frames per second burst speed is modest. But remember: this camera isn’t built for sports or action — it's for fine art, portraits, and street photography where speed is less important than precision.
🛠️ 3. Design: Built for the Street
🧱 Magnesium Alloy Body
The RX1R III is built from magnesium alloy, making it sturdy but lightweight — ideal for travel or daily carry.
🖥️ Fixed Rear Display
In a controversial move, Sony removed the tilting display. You now get a fixed screen, which saves weight but can be tricky for low or high-angle shots.
🔍 2.36 Million Dot OLED EVF
Framing your shots is easy thanks to the high-res electronic viewfinder (EVF). It may not be the highest on the market, but it gets the job done well.
🌼 Macro Mode
You can flip a ring on the lens to enable macro mode, letting you focus on objects as close as 20cm — great for detail shots of food, flowers, or textures.
🆚 4. RX1R III vs. the Competition
| Feature | Sony RX1R III | Fujifilm GFX100RF | Leica Q3 |
|---|---|---|---|
| Sensor Size | 35mm Full-Frame (61MP) | Medium Format (102MP) | Full-Frame (60MP) |
| Lens | Fixed 35mm f/2 Zeiss | Fixed 55mm f/1.7 | Fixed 28mm f/1.7 |
| Price | $5,099.99 | $4,899.95 | $5,995 |
| Video | 4K @ 30fps, 1080p @ 120fps | 4K @ 30fps | 8K @ 30fps, 4K @ 60fps |
| Autofocus | AI Eye/Body Tracking | Phase Detection | Phase Detection + Eye AF |
| Screen | Fixed | Tilting Touchscreen | Tilting Touchscreen |
The Fujifilm GFX100RF offers more resolution and a larger sensor but in a bigger body. The Leica Q3 has better video specs and a classic design but is also more expensive.
Sony’s RX1R III hits a sweet spot for those who want portability and power, even if they’re giving up lens flexibility and screen mobility.
