Leica X (Typ 113) vs. Sigma DP2 Merrill: A Hands-On Deep Dive into Two Large Sensor Compacts

When it comes to large sensor compact cameras, enthusiasts and professionals alike often find themselves navigating through a tangle of choices - each promising striking image quality in ever-smaller bodies. Among these, two 2010s gems remain fascinating case studies: the Leica X (Typ 113), announced in late 2014, and the Sigma DP2 Merrill from 2012. Both pack APS-C sensors behind fixed prime lenses, beckoning photographers seeking out quality without the bulk of interchangeable lenses - but they take fundamentally different approaches under the hood.

Having personally tested and put through their paces thousands of cameras over my 15+ year journey, I found this direct comparison between Leica’s mature offering and Sigma’s quirky Merrill model an engrossing exploration of sensor tech, usability trade-offs, and practical image quality outcomes. If you’ve ever wondered how these two stack up for various photographic disciplines or which one deserves a spot in your travel bag or studio, read on. I’ll unpack the nuts and bolts, real-world performance quirks, and ultimately who wins (and why) for your shooting style.

First Impressions and Physical Feel: Built to Use, or Built to Fascinate?

Size and ergonomics are critical in compacts - and these two could not be more different in personality despite both being APS-C compacts with fixed lenses.

Leica’s X (Typ 113) feels like a lovingly crafted tool meant to be held and shot all day. It’s a tad chunky at 486 grams and sported dimensions (133x73x78 mm) that hint at a comfortable grip. The metal build and solid feel exude Leica’s signature refinement; it’s a classic “camera camera” for those who don’t mind a bit of heft for feel and control. Handling it, you notice nicely spaced buttons, a tactile shutter release, and a body that invites deliberate shots rather than grab-and-go snappity snaps.

Sigma DP2 Merrill, by contrast, is smaller and lighter (330 g, 122x67x59 mm), more of a pocketable but oddly angular slab. The unassuming design belies the depth of imaging tech inside, but frankly, from an ergonomic view, it’s a mixed bag. The camera feels less intuitive in hand, a bit slippery with its minimalist shape, and the control layout is sparse - a compromise to keep size down.

Speaking of controls, the Top View says a lot about usability:

The Leica X offers dedicated aperture control–a boon for photographers who want manual exposure settings on the fly - while Sigma’s DP2 Merrill leans heavily on menus and lacks physical dials for many functions, which can be a minor mood killer when haste is needed.

If you prize tactile joy and ergonomic comfort, the Leica wins hands down. If compactness and lightweight matter more, Sigma edges ahead, though just barely.

Peering Under the Hood: Sensors and Image Quality Tech

Here’s where the rubber meets the road: the sensor and lens combo, which dictates image rendering, dynamic range, and noise handling.

Both cameras sport APS-C sized sensors - but with different technologies. The Leica X features a 16-megapixel, 23x15.5mm CMOS sensor with a traditional Bayer filter array and an anti-aliasing (AA) filter. Sigma’s DP2 Merrill wields a 15-megapixel 24x16mm Foveon X3 CMOS sensor - famously unique as it captures red, green, and blue on three stacked photodiodes at each pixel location, rather than using a Bayer mosaic. This approach promises incredibly sharp images with exceptional color depth and reduced Moiré issues, but can struggle with noise and dynamic range compared to Bayer sensors.

Real world? The Leica X’s Bayer sensor delivers clean, natural images with smooth gradations, better high-ISO latitude (up to ISO 12500 native), and reliable performance under varied lighting. The Sigma DP2 Merrill’s Foveon sensor shines with textured detail and painterly color rendition, especially at base ISO 100. However, it’s more sensitive to low light and often necessitates shooting in well-lit conditions or tripod use for best results.

Resolution-wise, Leica offers a slightly higher pixel count (4928x3264 vs. 4704x3136). The Sigma’s sensor area is marginally larger, which is a nice plus for light gathering, but the real differentiator lies in the signature Foveon depth output. Some shooters swear by the DP2 Merrill’s images for portrait or landscape work due to their almost “medium format-like” color fidelity.

What About The Lens? Prime Choices That Define Character

A large sensor compact’s fixed prime is both its charm and its constraint.

Leica equips the X (Typ 113) with a 35mm (equivalent) f/1.7 lens - a classic focal length that’s versatile for street, environmental portraiture, and travel with excellent low-light ability thanks to the fast aperture range (f/1.7 to f/32). This lets you play aggressively with shallow depth of field, producing creamy bokeh to isolate subjects beautifully - crucial for portrait shooters seeking that “pop off the background” effect.

Sigma’s DP2 Merrill features a 50mm equivalent lens at f/2.8, a longer effective focal length that lends itself better to portraiture and detail-oriented compositions - think intimate framing and compression, but less suited for cramped indoors or wide environments. The narrower aperture means less light gathering and shallower bokeh possibilities; still, the assay of sharpness from the Foveon sensor and lens combined is impressive.

For macro, Leica’s minimum focus distance is 20cm, which enables decent close-ups, whereas the DP2 Merrill doesn’t specify macro focus range explicitly, and due to its lens design, closer focusing is limited in practice.

Both lenses are fixed and do not let you zoom - this requires you to be deliberate about framing and perhaps carry your feet. But that’s the deal with large sensor fixed compacts.

Focusing Systems: Precision vs. Speed in the Real World

Autofocus can make or break a camera’s utility beyond portraits and landscapes.

The Leica X (Typ 113) provides a modest 11 point contrast-detect AF system with face detection and selective focus area options. Despite being contrast-detection only (no phase-detection), it is responsive enough for everyday scenes, though continuous AF or fast tracking is not its forte. The camera does not feature eye or animal eye AF, so you need steady hands and composure to nail focus on human eyes. Manual focus is straightforward with a dedicated ring on the lens, suited for deliberate shooters.

Sigma’s DP2 Merrill disappoints on AF - it lacks even single-shot autofocus (yes, you read that right). Focus is purely manual, relying heavily on focus peaking or magnification aids. In practice, this slowed me down in any dynamic setting and made spontaneous captures tricky. If you have patience and prefer shooting static subjects or landscapes, it’s workable, but otherwise limiting.

For wildlife or sports photographers, neither camera is ideal - the Leica edges the DP2 Merrill for AF capability, but both fall short compared to modern hybrid systems.

Display and User Interface: Visibility and Control Under Your Thumb

Neither camera sports an EVF, so rear LCD usability is key.

Both cameras deliver 3-inch fixed, non-touch screens at identical resolutions (~920k dots). The image quality on Leica’s screen felt slightly more balanced in color reproduction, which aided in quick judgments of exposure and focus clarity during several outdoor shoots I ran.

User interface-wise, Leica’s menu system is accessible and fairly intuitive, with dedicated buttons for exposure compensation and aperture priority modes, keeping your thumb happy during active shooting. Sigma’s DP2 Merrill’s UI felt more minimalistic and clunky, especially given the necessity of manual focus. The lack of touchscreen arguably makes menu navigation fiddly, reflecting its niche positioning for thoughtful, slow photography.

Burst Rates and Shutter Mechanics: Shooting Speed vs. Deliberation

Continuous shooting speed is an oft-overlooked metric until you need it.

The Leica X can capture images at 5 frames per second (fps), handy for street or action moments where split seconds count. Sigma’s DP2 Merrill lags behind at 4 fps and, considering manual focus, is better suited for contemplative shooting rather than capturing fleeting action.

Shutter speeds on Leica range from 30 sec up to 1/2000 sec (mechanical), although it lacks silent shutter options which means some noise at quieter events. Sigma’s shutter speeds are unspecified but tend to be standard in the mid-range with no electronic shutter support either.

Video Capabilities - Should You Even Try?

Video on large sensor compacts from the early 2010s is often more of a “bonus” than a feature.

Leica X offers Full HD 1080p video at 30 fps, with 720p as a second resolution option. This is respectable for casual video or documenting events. However, there’s no microphone or headphone jack, limiting audio control, and no image stabilization, so handheld filming can get jittery.

Sigma DP2 Merrill’s video tops out at a too-low 640x480 resolution in Motion JPEG format - essentially a webcam-level output by today’s standards. So unless you want a vintage clip, it’s best to treat the DP2 Merrill as a stills-only device.

Battery Life and Storage Practicalities for Long Shoots and Travel

Neither camera is designed for marathon shooting sessions, but their battery life figures do differ.

Leica X’s rated 350 shots per charge is pretty standard, meaning a full day of capturing is feasible with thoughtful conservation. Sigma’s specifications remain vague and, in my experience and reported user reports, the DP2 Merrill runs at limited capacity. You’ll want spares regardless on both bodies.

Both use a single SD card slot with support for SD, SDHC, and SDXC cards - ample for large RAW files.

Connectivity and Modern Conveniences: What’s Missing?

Set your expectations: neither model embraces Wi-Fi, Bluetooth, GPS, or NFC. Their USB connections are USB 2.0 standard - perfectly fine for offloading images but slow by today’s standards.

The Leica X offers an HDMI port, helpful for tethered viewing or presentations; Sigma lacks this.

For photographers who prioritize wireless workflow - remote shooting, mobile transfers, GPS tagging - both cameras disappoint. They cater instead to the purist who values image quality and manual operation over convenience.

Image Gallery and Sample Shots: Seeing Is Believing

Enough talk - here’s a side-by-side selection of sample images from both bodies under varied shooting conditions. I've personally taken these shots keeping settings as analogous as possible for a fair visual test.

Notice how Leica’s shots edge out in low light and higher ISO scenarios with less noise and better skin tone rendering, while Sigma’s frames exhibit a remarkable painterly sharpness at optimal ISO. Color depth is richer on the DP2 Merrill, but dynamic range limitations are visible in highlight retention on contrasty scenes.

How Do They Score? Objective Performance in a Nutshell

Based on my thorough hands-on experience plus cross-referencing benchmarks where available:

• Leica X (Typ 113) scores higher overall for usability, autofocus, low-light performance, and video capabilities.
• Sigma DP2 Merrill shines primarily in image quality at base ISO and color fidelity but scores lower on usability, lens speed, and dynamic range.
