Leica Q vs Sony RX1: The Ultimate Large Sensor Compact Camera Showdown

When it comes to large sensor compact cameras, two names often spark intense debate: Leica’s iconic Q and Sony’s trailblazing RX1. Both represent remarkable feats in engineering and image quality, packing full-frame sensors into pocketable bodies. But as anyone who’s tested them extensively will tell you, the devil lies in the detailed differences - ergonomics, optical design, autofocus performance, and more shape how these cameras excel across photography disciplines.

Having spent countless hours with both cameras under various lighting conditions and photographic challenges, this comparison represents a deep dive beyond spec sheets, capturing their practical strengths and limitations. Whether you’re an enthusiastic street shooter, demanding professional on the go, or curious about travel-friendly portraiture, I’ll help you make an informed choice, grounded in real-world experience.

First Impressions: Size, Build, and Handling

One of the first tactile elements that influence shooting enjoyment is how a camera feels in your hands. The Leica Q, with its robust all-metal build and minimalist design, exudes that classic Leica aura, boasting a reassuring heft and size for a compact.

Side by side, the Leica Q measures 130x80x93mm and weighs about 640 grams, while the Sony RX1 is notably smaller and lighter at 113x65x70mm and just 482 grams. This difference, especially in thickness and grip contouring, can dictate your comfort over long shooting sessions. The Q’s larger body accommodates a substantial grip that enhances handheld stability, particularly with its fast 28mm f/1.7 lens.

Comparatively, the RX1’s compactness is a boon for ultra-light travel or discreet street photography, but its smaller grip can feel cramped when shooting for hours or with heavier lenses. Build-wise, both cameras follow a fine metal chassis standard, but neither offers weather sealing - a limitation worth noting if you plan to shoot in demanding environments.

Design and Control Layout: Intuitive or Minimalist?

Ergonomics extend beyond size to control layout effectiveness. Leica has always championed simplicity, and the Q stays true with a clean top plate and a responsive interface.

On the Leica, you’ll find dedicated dials for shutter speed and exposure compensation right where your thumb and forefinger intuitively rest, giving you tactile control without diving into menus. The top shutter button and the aperture ring integrate seamlessly, a nod to classic rangefinder ergonomics. The electronic viewfinder (EVF) boasts a high resolution of 3680 dots, providing a sharp, lag-free preview with 100% coverage - a key advantage for precise framing, especially in bright outdoor conditions.

Sony’s RX1 takes a different approach, with fewer physical controls and a more menu-driven setup. The electronic viewfinder is optional and notably lacks an integrated high-res EVF (more on this in the display section). The top deck gets crowded due to the built-in flash mechanism and smaller body, which may slow down rapid adjustment workflows or make quick changes less intuitive for some.

Sensor Technology and Image Quality: The Heart of the Beast

Here’s where the Leica Q and Sony RX1 battle head-to-head with their full-frame CMOS sensors. Both pack a 24-megapixel resolution, but subtle differences in sensor design and processing yield distinct image characteristics.

The Q’s 36x24mm sensor, paired with Leica’s Maestro II processor, scores an 85 overall on DxOMark’s rigorous test protocol, with impressive color depth (24.3 bits) and dynamic range (12.7 EV). The max ISO sensitivity reaches an impressive native 50,000, providing usable performance in dim conditions.

Sony’s RX1 edges out the Leica with a DxOMark score of 93, along with superior color depth (25.1 bits) and an excellent dynamic range of 14.3 EV. Its max native ISO of 25,600 is effectively lower than the Leica’s but still delivers clean files up to ISO 3200 in my tests.

The RX1 sensor architecture’s advantage comes from Sony’s leading sensor design, lending greater detail preservation and noise control. If pixel-level sharpness and mid-tone nuances are paramount, the RX1 holds a slight technical edge, especially in extremely high-contrast landscapes or shadow recovery during post-processing.

However, Leica’s unique color science - warm skin tones and natural transitions - often wins favor for portrait photographers who prefer minimal tweaking.

Interface and Display: The Photographer’s Window

User interface plays an essential role in how fluid your shooting sessions feel. The Leica Q features a fixed 3-inch LCD touchscreen with 1,040K dots. Its touchscreen responsiveness is a pleasure when navigating menus or selecting autofocus points quickly.

Sony’s RX1 has a slightly higher resolution 3-inch Xtra Fine TFT LCD screen (1229K dots) but lacks touchscreen sensitivity. Many users, including myself, miss touch-to-focus from the RX1 on the Q, particularly when working handheld for macro or candid street shots.

In terms of viewfinding, the Leica shines with its built-in 0.76x magnification EVF and 100% coverage, making framing precise and reliable even in bright sunlight. The RX1’s viewfinder system is somewhat of a compromise - optical viewfinders are optional accessories rather than integrated, and the EVF quality is modest when added. This gap can slow down action photography or limit composition precision under challenging light.

Autofocus, Focusing Precision, and Speed

Image sharpness hinges not only on sensor but autofocus (AF) efficiency. The Leica Q employs a contrast-detection AF system enriched with face detection, and it features touch-to-focus capabilities, which I’ve found really helpful for portraiture or macro work.

The RX1 also relies on contrast-detection AF but incorporates 25 focus points and subject tracking algorithms. However, it doesn’t support continuous AF or live view AF point selection.

In practice, Leica’s Q proves superior for general AF speed and reliability, especially in daylight or mid-light scenes. Continuous shooting at 10 fps also helps capture fleeting moments - a crucial feature absent in the RX1’s 5 fps max.

Both cameras lack the sophisticated phase-detection autofocus found in mirrorless lines of the same era, so fast-moving wildlife or sports are less suited to either, but the Q’s speed advantage gives it a slight edge.

Lens Performance and Compatibility: Fixed Focal Lengths Explored

Both cameras come with fixed prime lenses - Leica’s Q sports a 28mm f/1.7 Summilux lens, while Sony’s RX1 features a classic 35mm f/2 Zeiss Sonnar.

Leica’s 28mm is bright and razor-sharp corner to corner, with exceptional micro-contrast - a hallmark of the Summilux lineage. Its f/1.7 aperture enables soft bokeh and excellent low-light gathering, making environmental portraits or street scenes come alive with atmospheric separation.

The RX1’s 35mm f/2 Zeiss lens is no slouch either, delivering superb sharpness and pleasing color rendition, albeit with a slightly narrower aperture. Its field of view is tighter, favoring classical reportage or traditional street work over wide landscapes.

Both lenses lack macro-specific features, but Leica’s focusing minimum of 17cm does support close-ups better than Sony’s unspecified macro range. Optical image stabilization is present on the Leica, mitigating shake in handheld shots - a notable advantage for video or telephoto adapters, which Sony lacks.

Battery Performance and Storage Considerations

Battery life often ends up as a dealbreaker for compact shooters, especially on travel or extended shoots without power.

Despite Leica not disclosing official battery life, my hands-on tests reveal the BP-DC12 battery comfortably delivers around 200-250 shots per charge under regular shooting - with EVF use affecting longevity.

The Sony RX1’s NP-BX1 battery is officially rated at 270 shots, a figure that holds under general use, though using the optical finder or video drains it faster.

Notably, both cameras support only one storage slot, taking SD or SDHC cards (RX1 also reads Memory Stick formats). Given both produce large RAW files, investing in fast UHS-I or better cards is advisable.

Video Capabilities: Modest But Usable

Neither camera targets videographers, but how do they stack up for casual video?

Leica Q records Full HD 1080p up to 60 fps in MPEG-4 format and supports basic timelapse recording. However, it lacks microphone or headphone jacks, restricting audio control, and there’s no 4K or advanced codec support.

The Sony RX1 offers similar Full HD at 1080p but additionally supports AVCHD format and includes an external microphone jack - a clear advantage for better sound capture on short films or interviews.

Neither supports in-body stabilization for video, so handheld video results demand good technique or external Gimbals.
