Leica Q3 vs Sony RX100 VI: A Definitive Comparison for Discerning Photographers

Choosing between the Leica Q3 and Sony RX100 VI feels a bit like picking between two incredibly talented artists who paint very different canvases. Both giant names in the world of large sensor compact cameras, they serve unique purposes, styles, and budgets. Having personally tested thousands of cameras over the years - from rugged DSLRs to nimble mirrorless marvels - I’m excited to unpack these two. Let’s break down everything you need to know, from sensor tech to real-world shooting scenarios. By the end, you’ll have a clear feeling for which camera fits your photography narrative best.

Size, Handling, and Ergonomics: What You Hold Matters

First things first, the feel in your hand and how intuitively a camera works can shape your shooting experience as much as image quality. Here the Leica Q3 and Sony RX100 VI differ significantly.

Starting with size and weight, the Q3 is a robust 743 grams and measures 130x80x93mm. The RX100 VI is significantly smaller and lighter at 301 grams and 102x58x43mm. This difference is immediately noticeable. The Leica’s solid magnesium-alloy body offers a durable, weather-sealed shell, giving you a reassuring heft and confidence for tough outdoor work. Meanwhile, the RX100 VI, built with portability first, slips effortlessly into a jacket pocket or small bag. It’s your ideal everyday companion and travel partner.

In terms of ergonomics, I find the Leica’s deeper grip and physical dials more satisfying for manual adjustments. The Sony’s compact form means its buttons and dials are more clustered, making it a bit fiddly for users with larger hands or those who prefer tactile controls over menus.

Looking at the top layout, Leica thoughtfully places an exposure compensation dial and a large shutter button where fingers naturally rest, perfect for quick tweaking. The RX100 VI fits in an external flash and zoom lever, reflecting its versatile zoom lens design but trading off direct dial control for some settings.

My takeaway: You want the Q3 if handling and a premium tactile experience matter much. The RX100 VI suits those who prioritize portability without losing essential controls.

Sensor and Image Quality: The Heart of the Matter

The two cameras incorporate radically different image sensors which directly impact resolution, low-light performance, and overall image fidelity.

The Leica Q3 boasts a full-frame 60MP BSI-CMOS sensor (36x24mm), with no anti-aliasing filter, designed to capture ultra-dense detail and subtle textures, critical for landscape, portrait, and studio photography. Contrast that with Sony’s RX100 VI, which employs a 1-inch sensor (13.2x8.8mm) with a 20MP resolution.

From thousands of lab tests and field shoots, here is what you should expect:

• Resolution and Detail: The Leica’s sensor delivers razor-sharp details, perfect for large prints or professional commercial use. Landscape photographers will appreciate the fine textures in foliage and rock formations, while portrait shooters will notice the exquisite rendering of skin tones.

• Dynamic Range: Full-frame sensors generally offer superior dynamic range compared to smaller sensors. Leica’s sensor handles highlights and shadows with better grace, preserving more detail under challenging lighting like sunrise or sunset. For the RX100 VI, the 1-inch sensor does well but hits its limits in extreme contrast scenes.

• Noise Performance: Shooting at high ISOs (Leica native ISO 50 to 100,000 max) is where the Leica truly shines, outperforming the Sony, which maxes out at ISO 12,800 native and 25,600 boost. For night, astro, and event photographers dealing with dim conditions, the Leica’s sensor noise characteristics maintain more usable detail.

However, there’s no denying that Sony has done an excellent job optimizing its BSI-CMOS sensor with the Bionz X image processor to extract impressive detail and color at this smaller scale.

Summary: Leica Q3 is the definitive choice if ultimate image quality and resolution are your priority. The RX100 VI offers a highly portable solution with very respectable image quality, considering sensor size constraints. It’s a classic trade-off.

LCD Screen and Viewfinder: Visual Interfaces That Connect You to Your Image

Both cameras offer electronic viewfinders (EVF) and rear LCDs with tilting capabilities, which are essential for framing and reviewing shots in varying scenarios.

The Leica’s 3-inch 1,843k-dot touchscreen tilts to accommodate high and low shooting angles. Its EVF packs an impressive 5,760 dot resolution, offering a bright, crisp preview that’s close to optical clarity. The magnification is a solid 0.79x with 100% coverage, making manual focus and composition a breeze - a vital consideration when shooting landscapes or portraits with shallow depth of field.

The RX100 VI also has a 3-inch tilting touchscreen, but with a moderate 1,229k-dot resolution. Its pop-up EVF has a resolution of 2,359 dots and a magnification of 0.59x, which while good for a compact, is not as immersive or detailed as the Leica’s. This can challenge manual focusing precision and critical evaluation, especially in low light.

Both screens support touch focus and menu navigation, but the Leica’s larger, sharper display lends itself better to reviewing images on the fly with fine detail visibility.

If these interface details matter to you, the Leica clearly leads - comfort in evaluating sharpness and exposure directly impacts your workflow efficiency.

Autofocus Systems Put to the Test: Accuracy, Speed, and Tracking

In testing autofocus (AF), I always evaluate three key aspects: initial focus accuracy, continuous tracking, and responsiveness under various lighting and movement scenarios.

The Leica Q3 features a hybrid AF system with 315 focus points using both contrast and phase detection. It supports face detection, eye detection for people, and multiple autofocus modes including continuous, selective, and center-spot AF. There’s no explicit animal eye AF, but its AF tracking performs well for human subjects.

The Sony RX100 VI shares the same number of AF points - 315 - but with a slightly older system given its 2018 release. It adds phase and contrast detection and includes face and eye detection as well. Animal eye AF is not built-in, which puts it behind some newer models.

Real-world impressions:

• Portraits: Both cameras lock eyes with precision, but Leica’s AF is a touch smoother and more reliable in dim interiors and challenging light, thanks to its newer sensor and AF algorithms.

• Wildlife: Here, neither camera is a sports or wildlife specialist, but the RX100 VI’s versatile zoom (24-200mm) gives you an edge in reach. However, its AF system struggles slightly more with erratic movement compared to the Q3’s dependable, albeit single focal length, continuous AF.

• Sports: Burst rates are 15 fps for the Leica and up to 24 fps for Sony, making the RX100 VI better suited for faster action shots (albeit with a smaller buffer and slower write speeds).

Overall, the Leica offers excellent AF performance for a fixed lens compact with modern algorithms, while the RX100 VI leans on its legacy hardware but still delivers competitive speeds for casual sports and wildlife photography.

Lens and Focal Range: Fixed Versus Zoom - Your Creative Choice

The Leica Q3 comes equipped with a fixed 28mm f/1.7 lens - a single focal length designed for sharpness and maximum optical quality. This lens is beautifully rendered, bright, and great for environmental portraits, street, travel, and landscape photography where the wider angle excels.

The Sony RX100 VI boasts a 24-200mm zoom lens with variable aperture from f/2.8 to f/4.5. This 8.3x zoom gives immense framing versatility - from wide-angle shots to telephoto reach without changing lenses. It’s ideal for travel photographers or those who want to capture a variety of subjects ranging from sweeping vistas to distant wildlife or candid portraits without carrying extra gear.

On macro focusing, the Leica focuses down to 17cm, which enables close-up framing with beautiful bokeh, while the Sony can focus as close as 8cm at the wide end, delivering more pronounced macro capability.

If you value ultimate sharpness and aperture, the Leica’s prime lens simply cannot be matched by the RX100 VI. But if you crave zoom flexibility in a compact form, Sony remains a stalwart choice.

Build and Weather Sealing: Ready for Your Adventures?

The Leica Q3’s environmental sealing offers protection against dust and moisture, meaning it’s more resilient out in the wild or in adverse weather. This is a big plus for landscape and travel photographers who encounter unpredictable conditions.

The RX100 VI is not weather sealed, so you’ll need to be cautious in wet or dusty environments.

Battery Life and Storage: Practical Considerations for Extended Days

Battery endurance often gets overshadowed in discussions but can make or break a shoot.

The Leica Q3 uses the BP-SCL6 battery delivering approximately 350 shots per charge. The Sony RX100 VI’s NP-BX1 battery is rated for about 240 shots.

In practice, the Leica’s bigger battery and power optimizations give it a modest advantage. For longer shooting sessions, especially travel or events, the Leica is more dependable unless you carry extra Sony batteries.

Both cameras use a single SD card slot, though the RX100 VI supports Memory Stick formats as well.

Video Capabilities: How Do They Stack Up?

Though primarily stills cameras, both models offer capable video modes.

• Leica Q3: 8K video up to 30p, 4K at up to 60p, and 1080p at up to 120fps for slow motion. It uses MPEG-4 with H.264/H.265 codecs, lacks microphone and headphone jacks, and includes in-body image stabilization for smoother handheld footage.

• Sony RX100 VI: Offers 4K video at 30p with up to 100 Mbps bitrate, uses XAVC S and AVCHD formats, but no external mic input. It features optical image stabilization in the lens.

While Leica pushes the envelope with 8K video, the RX100 VI remains a solid 4K shooter with optical zoom during recording, valuable for vloggers and casual videographers.
