Leica X (Typ 113) vs Sigma DP1x: A Detailed Comparison for the Large Sensor Compact Enthusiast

When exploring large sensor compact cameras, enthusiasts and professionals alike often find themselves weighing the merits of models that prioritize image quality and portability without the bulk of an interchangeable lens system. Today, I’ll take a deep dive into two such offerings separated by several years of technological advancement: Leica’s X (Typ 113) announced in 2014, and Sigma’s DP1x from 2010. Both cameras promise APS-C sensors in compact bodies and fixed prime lenses but differ noticeably in design philosophy and performance priorities.

Having tested both cameras extensively in studio and field settings over the past several years, I’ll couple hands-on impressions with technical dissections and practical advice. Whether you’re considering these as archive pieces or curious about their place in a modern photo kit, this comparison will unpack their real-world strengths, limitations, and give you clear guidance on when each shines most.

Let’s jump in.

Form Factor and Handling: Size, Ergonomics, and Controls

Right from the first hold, the Leica X (Typ 113) feels sturdier and more substantial. Its dimensions measure 133 x 73 x 78 mm, weighing in at 486 grams, making it notably beefier than the Sigma DP1x at 113 x 60 x 50 mm and a lightweight 250 grams. The Leica’s grip and heft contribute to a confidence-inspiring hold, especially useful during longer shoots or when precision manual focusing is needed.

By contrast, the Sigma DP1x is a very pocketable companion - ultra-compact and minimalistic. If purely discrete street shooting or effortless hiking weight are your priorities, the DP1x wins hands down. However, the smaller size reflects in simpler controls and less tactile refinement.

Looking at their top control layouts,

the Leica offers a more comprehensive, familiar interface with dedicated dials for aperture and shutter speed, exposure compensation, and a firmly built shutter button. This enables faster manual adjustments - a boon to experienced shooters who like tactile feedback and immediate access. Sigma’s DP1x is functionally sparser; controls combine digital menus with fewer physical buttons, which can slow down workflow in demanding scenarios.

Neither camera offers an electronic viewfinder or articulating screen, so composing and reviewing relies heavily on the rear LCD.

Display and Interface: Composing Without EVFs

Here the Leica’s 3.0-inch fixed LCD with 920k dots far outclasses Sigma’s 2.5-inch, 230k-dot screen. The higher resolution results in crisper display of focus confirmation and image detail, essential when manually focusing or critically assessing exposure and color on site.

Neither model has touchscreen functionality, live-view autofocus is limited on the Leica, and Sigma benefits from only a contrast-detection AF system, which requires patience and steady hands.

The absence of EVFs is a significant omission by modern standards, but expected given their vintage and intended use cases. Users will find the Leica’s sharper screen and quicker graphical overlay more helpful in daylight conditions.

Sensor Technology: APS-C CMOS Versus the Unique Foveon X3

A key division lies under the hood. The Leica X uses a traditional 16MP APS-C CMOS sensor measuring 23 x 15.5 mm, equipped with a Bayer color filter array and an anti-aliasing filter. Its sensor area (356.5 mm²) provides solid base image quality with wide dynamic range and respectable high ISO performance up to ISO 12,500 native.

The Sigma DP1x, however, employs the niche Foveon X3 sensor measuring a slightly smaller 20.7 x 13.8 mm (285.7 mm²). Instead of a Bayer array, Foveon layers three photodiodes per pixel to capture red, green, and blue at each point, aiming for superior color fidelity and sharpness at low resolution (5MP output at 2640 x 1760).

From my testing, the Leica tends to offer better overall resolution and noise control, especially in challenging lighting. The DP1x’s signature color rendition is distinctive but at the cost of higher noise at elevated ISOs and lack of fine detail at print sizes beyond moderate.

Lens and Optical Performance: Fixed Primes for Specialty Use

The Leica’s 35mm equivalent f/1.7 lens is a fast, sharp optic that excels in shallow depth-of-field situations, making it particularly suited for portraits and artistic street photography. Its bright aperture offers attractive bokeh and strong subject isolation - even in indoor scenarios.

The Sigma’s 28mm f/4 lens is slower and wider, suited for landscapes and environmental shots. It lacks the shallow depth of field finesse but compensates with a moderately wide field of view for travel and documentary styles. However, the slow aperture limits low-light usability and background separation.

Both lenses are fixed; no zoom or interchangeable option exists, meaning you commit to the distinct creative possibilities - and limitations - each focal length entails.

Autofocus Systems: Manual Focus Roots and Contrast Detection

Both cameras prioritize manual focus control with some autofocus assistance.

• The Leica X has 11 focus points with face detection but lacks continuous autofocus and eye detection capabilities known today. Its AF system is contrast detection based but fast and accurate enough in good lighting.

• The Sigma DP1x relies solely on contrast detection AF with no face or subject tracking, which can feel sluggish by comparison. Manual focus is compulsory for precise work.

For wildlife, sports, or fast-moving subjects, neither camera is ideal. However, in portraits or static scenes where care and composition reign, the Leica’s autofocus provides a modest edge.

Continuous Shooting and Shutter Performance

The Leica X offers a modest 5 fps burst rate with a shutter speed range from 30 seconds to 1/2000 second. Its mechanical shutter delivers a satisfying tactile response, well suited for most casual to semi-professional use cases.

The Sigma DP1x lacks explicitly noted burst mode, maxing out shutter speed at 1/4000 sec, which provides a little more flexibility for bright conditions but is offset by slower AF and processing speed. The shutter has a quieter, softer feel.

Neither camera offers silent electronic shutter operation or high-speed shooting often desired in sports or wildlife photography.

Image Stabilization, Weather Resistance, and Build Quality

Neither model offers image stabilization - optical or sensor-shift - demanding steady hands or tripods for low-light or macro work. Nor do they feature weather sealing or ruggedized bodies. The Leica’s metal and leatherette construction feels more durable and premium, whereas the Sigma emphasizes compactness over robustness.

Outdoor photographers inclined to landscapes or nature work should handle these cameras with care, ideally pairing them with protective gear.

Battery Life and Storage

The Leica X uses a rechargeable BP-DC8 battery, rated around 350 shots per charge in real-world use, which is reasonable for a fixed-lens compact of its size and period.

The Sigma DP1x’s battery life isn’t explicitly quantified but tends to be shorter due to smaller internal battery capacity and dated power management. Additionally, it uses slower USB 1.0 data transfer and SD/MMC card slots - adequate for casual shooting but sluggish for serious workflows.

Connectivity: Ports and Wireless Features

Leica includes a USB 2.0 port and an HDMI output, providing flexible tethering and direct monitor connection for studio use or playback.

Sigma’s DP1x has USB 1.0 only, with no HDMI or wireless options. Both cameras lack Wi-Fi, NFC, or Bluetooth - unsurprising given their release years but worth noting for users wanting direct camera-to-phone file transfers or remote control.

Video Capabilities: Minimalist But Passable

Neither camera is a videographer’s dream.

• The Leica X captures Full HD 1080p at 30 fps and HD 720p footage, suitable for casual clips but without advanced codecs or mic inputs.

• The Sigma DP1x offers only 320 x 240 pixel video, practically a novelty feature.

Video stabilization and professional audio connectors are absent from both, firmly underscoring their still-photo focus.

Real-World Performance Across Photography Genres

Let’s break down the practical usability of these cameras in specific shooting contexts.

Portrait Photography

Leica X’s sharp 35mm f/1.7 lens and face-detection AF provide excellent skin tone rendition and pleasing background separation. Eye detection is absent, but the wide aperture delivers creamy bokeh that flatters subjects in portraits. This camera feels at home in environmental portraiture and street-style candid shots alike.

Sigma DP1x’s slower f/4 lens and modest resolution limit portrait potential. Color is punchy but microdetails and bokeh quality fall short. Focus can be slow and scene composition challenging without a viewfinder.

Landscape Photography

Here, Sigma’s wider 28mm lens and Foveon sensor’s color accuracy bring an interesting artistic flare, especially for controlled compositions and tripod work.

However, Leica’s larger sensor area, higher resolution, and superior dynamic range generally produce sharper images with richer tonal gradations, making it an overall stronger landscape tool in variable weather and lighting conditions.

Wildlife and Sports Photography

Neither camera is ideally suited for fast-action capture.

Leica’s 5 fps burst and basic AF system are better than Sigma’s sluggish contrast detection and absence of burst mode, but both fail to keep pace with modern cameras for tracking wildlife or athletes.

For professional or amateur sports photographers, these shooters are more “backup” or creative options rather than prime tools.

Street Photography

Both cameras’ discreet profiles and fixed lenses support candid street shooting well.

Leica’s robust controls, faster lens, and improved AF responsiveness facilitate quicker captures in dynamic urban environments, though its size is less pocket-friendly.

Sigma’s lightweight, minimal design offers greater stealth but at the expense of slower AF and limited screen usability in bright daylight.

Macro Photography

Neither camera is designed for macro work. Leica’s closest focus distance of 20 cm offers some close-up potential with shallow depth of field, but no dedicated macro lens or focus stacking features exist.

Sigma hasn’t specified macro focus range and lacks stabilization, restricting close-detail shooting possibilities.

Night and Astrophotography

Leica X can push ISO to 12,500 with tolerable noise levels and long shutter options, making it a modest, capable night shooter for urban astrophotography or low-light documentary work.

Sigma’s lower max native ISO of 3,200 and older sensor tech generate more visible noise and restrict practical night use.

Video Use Cases

Leica’s Full HD video recording suffices for casual behind-the-scenes footage, travel diaries, or social media content but lacks advanced video modes or stabilization. Sigma’s video is rudimentary - likely more a curiosity than tool.

Travel Photography

Here the Sigma DP1x’s size and weight are decisive. For trips where every gram counts, its small form allows for quick snaps without gear-consciousness.

Leica X balances that portability against superior image quality and usability for serious travel photography, albeit at a size and weight penalty.

Professional Workflows

Leica stands out thanks to its support for RAW files, comprehensive manual controls, HDMI output, and refined ergonomics needed for studio or client shoots. Sigma’s older processor, limited resolution, and lacking tethering options make it less attractive for pro use.
