Though similar in category, these two are from very different design philosophies: Leica’s heritage with premium, fixed-lens craftsmanship versus Sony’s powerhouse tech innovation packed into a compact body.

In this thorough comparison, I’ll break down every important aspect from image quality to autofocus, and explore how these cameras perform across popular photography disciplines. I’ll also talk money and value because, at around the $1000 mark, choosing the right camera isn’t just about specs - it’s about who you are as a shooter.

Let’s dive in.

Size, Ergonomics, and Build: Holding the Cameras in Hand

One look at the Leica D-Lux Typ 109 and Sony RX100 V reveals contrasting design approaches engineered for different user preferences.

Physically, the Leica D-Lux Typ 109 is noticeably larger and chunkier at 118 x 66 x 55 mm, with a heftier 405g weight. It feels substantial and reassuring in hand, benefiting from the smooth metal body and the tactile precision Leica is renowned for. This size accommodates a generous grip and intuitive button placement, favoring controlled, deliberate shooting over fast snappy snaps.

The Sony RX100 V, by contrast, is compact and slender - 102 x 58 x 41 mm, weighing just 299g - making it pocketable and truly travel-friendly. Its smaller size supports quick grab-and-go scenarios but can feel a little cramped for photographers with larger hands. Sony compensates with a well-thought-out control layout accessed via a tilting touchscreen and a highly customizable function menu.

If you prioritize physical handling comfort - say for landscape or portrait work where you linger over compositions - the Leica edges ahead. For rapid street shooting or travel where minimalism and portability are king, Sony’s RX100 V carries the day.

Sensor and Image Quality: The Heart of the Camera

Leica equips the D-Lux Typ 109 with a Four Thirds sensor measuring 17.3 x 13 mm and packing 13 megapixels, while Sony’s RX100 V features a 1-inch BSI-CMOS sensor, smaller at 13.2 x 8.8 mm, but with a higher 20 MP resolution. Don’t let these numbers mislead you without context.

The Four Thirds sensor roughly doubles the surface area of the RX100 V’s 1-inch sensor (224.9 mm² vs 116.16 mm²), which typically translates to superior noise performance and dynamic range. However, Sony’s back-illuminated sensor design and modern Bionz X processor partly bridge that gap with excellent low-light capabilities and higher ISO usability.

In practice, Leica’s larger sensor delivers smoother gradations, richer color depth, and less luminance noise beyond ISO 800, especially vital when shooting in flagrant shadows or subtle mid-tones - think moody portraits or gentle dawn landscapes.

Sony’s sensor, though smaller, pushes a higher resolution advantage, offering crisp details and excellent resolving power at base ISO, which benefits applications requiring tight crops or large prints, like detailed wildlife or macro shots.

Both cameras include optical low-pass (anti-aliasing) filters, slightly limiting super-sharpness but preserving detail without annoying moiré patterns - a balanced approach for most casual-professional uses.

Bottom line: Leica wins hands down for smooth tonal transitions and low noise at high ISO, great for portraits and nuanced landscape work. Sony brings more megapixels for fine detail hunters but handles noise well too.

Lens and Optical Performance: Versatility vs Aperture

The fixed zoom lens defines much of what these cameras can do, so let’s look closely.

Leica’s D-Lux offers a 24-75mm equivalent lens aperture range of F1.7 to F2.8, a bright, fast zoom, while Sony’s RX100 V sports a 24-70mm equivalent zoom with F1.8 to F2.8 aperture.

Along with the Leica’s slightly longer zoom, the faster max aperture on the wide end (F1.7 vs F1.8) allows more light for shallow depth-of-field effects and low-light shooting. When chasing creamy bokeh in portraits or isolating subjects, that extra stop of brightness on Leica’s wide end counts.

Sony’s lens is no slouch, though - its sharpness across the zoom range is excellent, with less chromatic aberration and edge softness. Sony also edges Leica on close focusing distance at 5 cm macro capability versus Leica’s very tight 3 cm minimum focus - which suits true macro work better on Leica.

Both cameras employ optical image stabilization systems, crucial for handheld shooting in tricky conditions. Leica’s is well-tuned but Sony adds advanced gyroscopic stabilization aiding videography and burst shooting.

Control Layout and User Interface: Intuition Meets Tech

Handling a camera in the field reveals the maturity of its user interface.

Leica’s UI is minimalistic but premium, with dedicated dials for shutter speed, exposure compensation, and aperture - ideal if you’re the type who enjoys manual control without menu diving. Buttons are well-spaced and comfortable, though the camera lacks touchscreen functionality, which might feel a bit antiquated in today’s world.

The Leica’s 3-inch fixed rear screen (921k dots) and 2.76 million dot electronic viewfinder (EVF) offer great color fidelity and a natural shooting experience. EVF magnification of 0.7x and 100% coverage aid precise composition.

Sony’s RX100 V opts for a more digital approach, with a tilting 3-inch rear LCD (1.23 million dots) but no touch capability, requiring navigation via dials and buttons. The RX100 V does not offer an articulated touchscreen, unlike some later RX models, but the bright EVF simplifies shooting in sunlight with a sharp 2.36M dot display.

Sony includes a broader AF point system (315 points vs Leica’s modest 49), accessed through menus - not always intuitive but powerful once mastered.

The Leica controls feel vintage-classic with tactile satisfaction, Sony is more button-and-wheel-centric with tech-heavy customization. It depends if you want analog charm or digital precision in your grip.

Autofocus and Speed: Catching the Decisive Moment

Anyone shooting action - be it wildlife, sports, or fast street scenes - needs a dependable autofocus system combined with high burst rates.

Sony dazzles with 315 AF points employing hybrid phase and contrast detection, affording fast, accurate focus locks and smooth tracking, even on erratic subjects. The RX100 V’s continuous shooting rate of 24 fps with autofocus and exposure tracking is staggering for a compact, approaching some flagship mirrorless speeds.

Leica’s autofocus, while competent with 49 contrast detection points, lacks phase detection, resulting in slower and sometimes hesitant focus acquisition, notably in low-contrast or rapid movement scenes. Its continuous shooting max rate of 11 fps is respectable but can’t match Sony’s blistering pace.

For wildlife or sports photographers, Sony wins decisively here, able to nail unpredictable subjects with less hunting and frustration.

Video Capabilities: Crafting Moving Pictures

Both cameras offer solid 4K video recording at 30p, but their video features differ significantly.

Sony’s RX100 V records UHD 4K at 100 Mbps using XAVC S codec for high-quality footage with minimal compression artifacts. It also supports Full HD at 60p with AVCHD and MP4, plus linear PCM audio recording, though lacks external microphone input. The RX100 V’s electronic stabilization is refined, smoothing handheld clips for travel or run-and-gun videography.

Leica’s D-Lux also supports 4K (at 30p / 24p) but at lower bitrates and MPEG-4 format, which may not provide the same video fidelity or flexibility. The Leica lacks built-in microphone or headphone ports, limiting audio monitoring and professional sound capture.

Sony’s more modern processing engine and video codecs make it the stronger choice for hybrid shooters who want excellent stills and video performance alongside.

Battery Life and Storage: Staying Powered Out There

Every enthusiast knows a camera’s usefulness extends only as far as its battery and storage.

Leica D-Lux Typ 109 delivers around 300 shots per charge, edging Sony’s RX100 V at 220 shots modestly. In the field, this difference translates to fewer battery swaps and longer shooting sessions without power drains, important for travel and event shooting.

Sony supports both SD cards and Memory Stick formats, adding versatile media options; Leica limits you to SD/SDHC/SDXC UHS-I cards, which is standard.

While neither excels for marathon shooting compared to larger mirrorless bodies, Leica offers slightly better endurance - likely due to less power-intensive sensor and operational design.

Connectivity: Sharing in a Snap

Connectivity is vital today for instant image sharing or remote control.

Both cameras include built-in Wi-Fi and NFC for smartphone pairing, but neither offers Bluetooth (still rare in their generation cameras). Leica adds NFC support, simplifying one-tap sharing, while Sony offers wireless control with its downloadable app, enabling remote triggering and settings adjustment.

On wired connections, both cameras use USB 2.0 and micro HDMI ports for image transfer and external display, though no USB charging or tethering is available.

Weather Sealing and Durability: Ready for the Elements?

Neither the Leica D-Lux Typ 109 nor the Sony RX100 V offers significant environmental sealing. Both are susceptible to dust and moisture ingress, so protective care is advised for outdoor photographers.

This lack of weather resistance nudges these cameras more toward controlled shooting environments or situational use rather than rugged adventure photography.
