The Sony RX1R III is smaller, lighter, and has more advanced autofocus than the Leica Q3, making it better for travel and for capturing moving subjects. The Leica Q3 is more versatile with a tilting touchscreen, better battery life, weather sealing, image stabilization, and a faster, wider 28mm f/1.7 lens compared to the Sony’s fixed 35mm f/2.0 lens. The choice depends on priorities: prioritize compactness and speed with the Sony, or versatility and a premium experience with the Leica.
The cobblestone alleyway in Lisbon glowed amber under streetlights. Rain misted the air. I raised my camera just as an old tram rattled past, its windows blazing like gold bars in the gloom. In that moment, the camera in my hand wasn’t just a tool — it felt like an extension of my vision.
For years, I chased that feeling: a full-frame sensor in a pocketable body for street photography that disappears until the moment demands it. My quest narrowed to two legends: the Sony RX1R III and the Leica Q3.
Here’s how that battle played out in my real-world shooting.
The Compact Contender: Sony RX1R III

When Matt Granger called it “ideal for discreet shooting,” he wasn’t kidding. The RX1R III vanishes in a jacket pocket. Its 35mm f/2 Zeiss lens became my daily companion during a chaotic Tokyo trip. Shoving through Shinjuku Station crowds?
No one noticed the tiny Sony. The AI autofocus felt like witchcraft — locking onto a stray cat’s eyes mid-pounce or tracking a cyclist weaving through traffic. That 61MP sensor delivered brutal sharpness, perfect for cropping into street portraits unnoticed.
But reality bit:
- That fixed screen? Brutal for low-angle shots over food markets.
- No weather sealing meant sweating bullets in a sudden downpour.
- Battery life? I carried three spares. Always.
The Luxury Tank: Leica Q3

Then came the Leica Q3 — a camera that doesn’t whisper, it resonates. Shooting a foggy dawn in San Francisco, its 28mm f/1.7 Summilux sucked in light like a black hole.
The tilting screen was a revelation for candid waist-level shots. Weather sealing let me shoot confidently in coastal spray at Big Sur. That 8K video? I captured my nephew’s wedding with cinematic depth even Tony Northrup would approve of. Holding it feels like craftsmanship; the heft whispers, “I’ll outlive you.”
Yet friction existed:
- Size matters. The Q3 bulged in my slim travel sling.
- Autofocus hunted in dimly lit bars where the Sony sniped flawlessly.
- The price? Let’s just say it cost more than my first car.
The Crossroads: 35mm vs 28mm
This wasn’t specs — it was vision. The Sony’s 35mm framed scenes with narrative tension: a fisherman mending nets, isolated in the frame. The Leica’s 28mm threw me into the scene: the bustling energy of a spice market, every sack and haggling vendor included. I craved the Sony’s intimacy for portraits but adored the Leica’s immersive storytelling.
The Verdict That Found Me
I bought the Sony. Its size and autofocus won my pragmatic heart for everyday carry. But six months later, I rented the Q3 for a coastal road trip. Standing knee-deep in Oregon surf, rain lashing the weather-sealed body, I understood Jonny Roams’ “premium experience” euphoria.
So who won?
Ironically, both. The Sony RX1R III is my “always with me” weapon — invisible, agile, ruthlessly smart. The Leica Q3 is my deliberate creative partner for projects where light, atmosphere, and tactile joy matter. One fits in my pocket; the other fits my soul.
