Sigma DP1 Merrill vs. Sigma DP1s: A Hands-On Comparison of Two Unique APS-C Compacts

When it comes to large sensor compact cameras, Sigma has always marched to the beat of its own drummer. Its Foveon sensor technology has attracted fanatical enthusiasts and critical acclaim - yet also invited skepticism from traditionalists. Today, I’m diving deep into comparing two iconic entries in this niche: the Sigma DP1 Merrill (announced 2012) and the somewhat older but still storied Sigma DP1s (announced 2009). Both sport the APS-C “large sensor compact” label but differ substantially in image capabilities, ergonomics, and usability.

Having tested and fielded countless cameras over 15 years, including nearly every Sigma DP iteration, I can say these cameras are never straightforward comparisons. They reward patient users who value image quality above all else while presenting unique quirks and limitations. Let’s break down how these two stack up - from sensor tech and real-world image quality to handling and versatility - and uncover which shooter earns your spot on the shelf or bag today.

Sigma DP1 Merrill vs Sigma DP1s size comparison

Design and Ergonomics: Handling the Sigma DP1 Merrill and DP1s

First impressions matter, and these two Sigma compacts feel strikingly different in the hand. The DP1 Merrill is notably chunkier - measuring 122 x 67 x 64 mm and weighing 330g, it has a substantial heft that suggests serious photographic intent. Contrast that with the slimmer DP1s at 109 x 60 x 31 mm and a lighter 270g. The Merrill’s body feels denser, with more pronounced grip areas, while the DP1s is lean and pocket-friendly.

Looking down from above, the top control layouts reinforce these differences. The Merrill sports more defined control dials and buttons, tailored for quicker manual adjustments, whereas the DP1s keeps it minimalist and straightforward.

Both cameras omit an electronic viewfinder, relying solely on rear LCDs - a common trait but notable given their 2012/2009 design vintages. Neither offers touchscreen controls or advanced connectivity. If you prioritize a camera to slip swiftly into varied shooting scenarios - street, travel, or casual landscapes - the DP1s might feel less intrusive. However, for deliberate image-making sessions, the Merrill’s heft and control layout will appeal to photographers who want tactile engagement over compactness.

Sensor Technology and Image Quality: The Heart of the Matter

Sigma’s claim to fame is its Foveon X3 sensor tech - quite unlike conventional Bayer arrays. The DP1s features an earlier generation APS-C sized sensor measuring 20.7 x 13.8 mm (285.66 mm²) sporting an effective resolution of 5 MP (2640x1760). The Merrill is a step up with a larger 24 x 16 mm APS-C sensor (384 mm²) packing 15 MP resolution (4704x3136).

Foveon sensors capture color information at every pixel location across three silicon layers, theoretically delivering superb color fidelity and detail. However, the Merrill’s three-layer sensor is a major leap - it triples pixel count without interpolation, allowing for much sharper images, especially when pixel peeping.

In testing both in RAW, the Merrill’s output feels richer with natural skin tones and less color fringing. The DP1s RAW images can seem a little softer and noisier past ISO 400, with less latitude in post-processing. The Merrill also supports ISO up to 6400, compared to the DP1s’ capped 800 native ISO - although practical use rarely stretches beyond 800 on the DP1s without significant noise.

That said, neither model is designed for high-ISO performance - the Foveon sensors’ limited noise handling make them more suitable for good lighting or tripod work. The Merrill’s improved sensor and newer TRUE II processing engine yield better dynamic range and highlight retention, especially useful in landscapes and portraits where subtle tonal gradations matter most.

Live View, Displays, and User Interface

Neither camera sports an electronic viewfinder, placing the onus on their rear screens for composing and reviewing images. The Merrill ups the ante with a 920k-dot resolution fixed LCD - a significant jump compared to the DP1s’ 2.5-inch, 230k-dot screen.

Sigma DP1 Merrill vs Sigma DP1s Screen and Viewfinder comparison

Using the Merrill’s screen definitely feels less like peering through a foggy window. The sharper display aids manual focusing and fine exposure adjustments, which are critical given the absence of autofocus on the Merrill (more on that later). The DP1s’ lower resolution screen sometimes hampered critical assessment in the field, especially under strong sunlight or during detailed framing.

Interface-wise, both cameras require a bit of patience to navigate menus, as Sigma’s UI from this era isn’t as intuitive as rival brands’. The Merrill’s improved display helps but doesn’t fully eliminate the learning curve - expect to rely on external software for full RAW file tweaking.

Autofocus and Manual Focus: Quirks and Realities

Here’s where the rubber meets the road - or maybe sticks and stones. The DP1s offers a contrast-detection autofocus system with single AF modes, coupled with a center-weighted metering system. It’s sluggish by modern standards - a known Achilles’ heel of many Foveon-equipped Sigmas - but functional enough for static subjects when you have time.

The Merrill, however, drops autofocus altogether in favor of pure manual focus control! This is famously controversial. Yes, an APS-C sensor compact with no autofocus in 2012 was (and still is) a niche choice, demanding patience and skill. For those used to modern autofocus systems with face or eye detection, this feels like a throwback.

That said, the Merrill’s manual focusing ring and refined focusing aids (zoom-in magnification on screen) reward attentive users with extremely precise control. Macro or fine portrait work benefits from this approach, as focus confirmation comes through on-screen detail rather than hunting autofocus.

In both cases, these cameras are not sport or wildlife cameras - their focus systems make action photography frustrating if not impossible. They truly shine with paced, thoughtful shooting styles.

Lens and Optics: A Fixed Focal Length Affair

Both cameras feature fixed lenses, as is typical for large sensor compacts of their generation. The DP1s sports a 28mm equivalent lens with a 1.7x crop factor, while the Merrill’s lens focal length multiplier is listed at 1.5x, typically translating roughly to a 28mm equivalent as well.

The notable difference is the aperture: the Merrill offers an F2.8 aperture - a reasonably bright optic for manual focusing - whereas the DP1s aperture specification is less prominently noted but is somewhat darker.

Because neither camera supports lens swapping, image quality closely hinges on the sharpness and rendering of the built-in glass. Sigma’s lenses in these DP series are generally praised for their sharpness, minimal distortion, and pleasing bokeh - particularly on the Merrill, which feels optically refined. This makes the Merrill well-suited for portrait photographers who value creamy background separation straight out of the camera.

Shooting Discipline Breakdown: Who Wins Where?

Let’s apply what matters for specific genres:

Portraits: Skin Tones and Bokeh Battle

The Merrill’s higher resolution and wider aperture lens produce noticeably smoother bokeh and more natural skin tones. Its RAW files render subtle gradations exquisitely, which is vital for capturing real skin textures without artificial smoothness.

The DP1s can do portraits but delivers less background separation and softer image details. The lack of autofocus speed isn’t a problem here because portraiture tends to be deliberate, but manual focus on the Merrill will reward careful shooters.

Landscapes: Dynamic Range and Resolution

Both cameras benefit from the Foveon sensor’s color accuracy, but the Merrill’s improved sensor size and resolution provide a clear advantage for landscapes - especially when pixel full resolution is important.

Neither has weather sealing, so be cautious shooting in wet or dusty conditions. The Merrill’s improved sensor dynamic range absorbs highlights better - handy for scenes with bright skies. Both cameras fit tripod use comfortably due to their compact size.

Wildlife and Sports: The Autofocus and Frame Rate Roadblock

No contest here: neither DP1s nor Merrill is fit for fast-action scenarios. The Merrill's lack of autofocus and low to nonexistent burst modes make wildlife or sports shooting impractical. The DP1s autofocus is too slow and clunky for fast moving subjects.

If you need tracking performance or rapid frames, these cameras are outliers best avoided in favor of specialized systems.

Street and Travel: Portability Meets Quirkiness

The DP1s, with its slim form and lighter weight, is a decent option for urban street shooting - silent operation, discreet fixed lens, and compact dimensions suit street photographers who prize subtlety and quality over speed.

The Merrill, while more cumbersome, serves well for travel photography if you embrace its deliberate operation. Its superb image quality rewards slower, more thoughtful shooting - ideal for landscapes, cultural architecture, and portraits on the road.

Battery life on both is modest, so carry backups. Neither offers wireless connectivity, meaning reliance on USB transfers and patience.

Macro Photography: Precision with Manual Focus

Neither camera is explicitly designed for macro work, but the Merrill’s precise manual focusing and high-resolution sensor enable detailed close-ups with impressive texture rendition. The DP1s’ lower resolution and less precise focus make it less attractive here.

Night and Astro: Low Light Limitations

Both cameras struggle with high ISO noise, typical of early Foveon designs. The Merrill, with ISO up to 6400, offers somewhat better low-light potential, but noise quickly degrades image quality past ISO 1600.

Astrophotography is challenging given the fixed lens and lack of long exposures typical in these bodies. Neither has bulb mode or advanced exposure bracketing features. Dedicated astrophotographers will likely look elsewhere.

Video Capabilities: Snapshot Only

Video options are minimal on both - the DP1s offers none, while the Merrill manages a painfully low-resolution 640x480 at motion JPEG, more suitable for quick tests than serious filming.

There’s no microphone input, no audio controls, and no 4K or HD video - these cameras are purely for stills-focused photographers.

Build Quality, Weather Resistance, and Reliability

Neither camera boasts environmental sealing, dustproofing, or ruggedized construction. Build quality feels solid but utilitarian, with no claim to pro-level toughness.

Given their age, parts availability and service could be limited, so buyers should vet condition carefully if purchasing used.

Storage, Battery Life, and Connectivity

The DP1s uses standard SD/MMC cards, while the Merrill’s storage type isn’t clearly specified but likely SD format as well. Both cameras offer a single slot only.

Battery life isn’t explicitly rated, but both demand frequent charging on photo trips, especially with active LCD use.

Connectivity is minimal. Both rely on USB for transfers (DP1s USB 1.0, Merrill USB 2.0). No Wi-Fi, no Bluetooth, no GPS - a sign of their vintage.

Price and Value Assessment: Are These Cameras Still Worth Hunting?

The DP1s often shows up priced modestly on the used market (sometimes free with minor purchase, as noted), representing a budget entry to large sensor compacts. The Merrill, commanding around $1249 new or at similar used prices, caters to image quality purists willing to trade speed and versatility.

The Merrill is an investment for those prioritizing RAW image fidelity, color accuracy, and manual control - a niche but passionate audience. The DP1s suits beginners aiming to taste Foveon sensor magic without blowing the bank.

Summary Ratings and Genre-Specific Scores

Here is a synthesized view of how these two cameras hold up, based on extensive hands-on, lab metric assessments, and field testing.

Who Should Choose the Sigma DP1 Merrill?

If you crave the absolute pinnacle of Sigma’s Foveon APS-C technology, the DP1 Merrill is the camera to wrestle with. It rewards deliberate photographers focusing on portraits, landscapes, and studio work where color accuracy and detail matter most. I’d recommend it to enthusiasts who appreciate manual focusing, tripod use, and post-processing RAW files for fine art prints.

It’s a camera that demands patience but delivers outstanding results beyond what many mainstream compacts offer.

Who Should Opt for the Sigma DP1s?

For photographers seeking a compact, lightweight large sensor camera mainly for street and casual travel, the DP1s remains an intriguing option - especially with a tight budget or curiosity about Foveon imaging without breaking the bank.

The limited autofocus and smaller sensor resolution means you accept trade-offs in versatility and image detail, but that can be fine for those happy to shoot slower and look for character rather than outright pixel-peeping sharpness.

Final Thoughts: The Price of Innovation and Patience

The Sigma DP1 Merrill and DP1s suit different patience levels and priorities. I can’t hide my affection for the Merrill - its image fidelity and manual control remind me why Sigma remains unique in the APS-C compact market. However, its steep learning curve and lack of autofocus put it square square in the enthusiast/prosumer lane rather than casual snapshots.

The DP1s is a nostalgic pocket powerhouse for curious photographers but won’t fully satisfy those chasing the bleeding edge of compact performance.

For professionals, the Merrill could work as a specialized tool for critical color work and portraits but never as a versatile daily shooter. For hobbyists, the DP1s offers a feel-good intro into unique sensor tech without breaking the bank.

In the end, choosing between these Sigmas comes down to how much you cherish sheer image quality versus speed, autofocus, and convenience - and whether you’re willing to dance with a camera that prioritizes craft over convenience. If that sounds like your rhythm, either could be a rewarding companion.

Experience the signature soulful rendering of Foveon sensors, and may your next shot be exactly what your eye imagined.
