Olympus Stylus 1s vs Sigma DP2 Merrill: A Deep Dive into Two Unique Compact Cameras

In the world of compact cameras, it's rare to find two models as distinct - as ambitious - as the Olympus Stylus 1s and the Sigma DP2 Merrill. Both were launched in the early to mid-2010s but approach photography from fundamentally different philosophies and engineering choices. The Olympus Stylus 1s leans into versatility with a superzoom fixed lens and modern touches, while the Sigma DP2 Merrill bets on its large APS-C Foveon sensor and prime lens for uncompromising image quality.

Having spent many hours testing and comparing both cameras across a wide spectrum of photography genres and real-world scenarios, I’m excited to share my detailed, hands-on insights. Whether you're a landscape shooter craving dynamic range, a portraitist chasing exquisite color depth, or a travel photographer looking for the perfect balance of size and capability, this comparison aims to help you make an informed choice grounded in practical use and solid technical evaluation.

First Impressions: Build, Size, and Handling

At a glance, both cameras occupy the compact/mirrorless niche, but their design philosophies diverge dramatically. The Olympus Stylus 1s adopts an SLR-like bridge camera form factor, weighing 402g and measuring 116x87x57mm. It feels robust in hand, with a comfortable grip, pronounced dials, and thoughtful placement of controls. The Sigma DP2 Merrill, lighter and slimmer at 330g and measuring 122x67x59mm, embraces a minimalist large-sensor compact design with few external controls - more of a camera for deliberate shooting.

The ergonomics of the 1s are notably superior for extended shooting. Its electronic viewfinder (EVF) provides 100% coverage and sharp 1440 resolution, giving me confidence in composition even in bright sunlight. The DP2 Merrill lacks a viewfinder altogether, which can be a dealbreaker outdoors or when shooting fast-moving subjects.

That said, the Sigma’s smaller footprint lends itself well to street and travel photography, where discretion is prized. You’ll intuitively reach for the Olympus’s tactile controls when you need quick manual adjustments, while the DP2 Merrill demands more patience and planning.

Top Panel and Control Layout: Precision vs Simplicity

A quick glance from above reveals Olympus’s adherence to traditional control schemes - with dedicated aperture and shutter dials, an exposure compensation dial, and a well-sized shutter button. These unused physical controls shine in sports or wildlife photography when split-second exposure tweaks are vital.

Conversely, Sigma takes a stripped-down approach, eschewing physical dials for a clean top plate. This minimalism can frustrate users used to quick manual controls. I noted the lack of exposure bracketing, white balance bracketing, and advanced flash control on the DP2 Merrill, which constrains creative flexibility, especially in dynamic lighting.

The Olympus 1s’s versatility extends with its tilting touchscreen LCD. While touch autofocus and menu navigation enhance usability, the Sigma DP2 Merrill sticks to a fixed 3-inch screen with limited resolution (920k dots), making precise manual focusing more challenging.

Sensor Technology and Image Quality: The Heart of the Matter

Here’s where these cameras part ways on a fundamental level, and I’ve found this difference speaks volumes about their target users.

The Olympus Stylus 1s sports a relatively small 1/1.7-inch BSI CMOS sensor sized 7.44x5.58mm, boasting 12MP resolution. While not large, this sensor benefits from a fast fixed f/2.8 lens with a versatile 28-300mm equivalent zoom range. The sensor’s back-illumination aids low-light performance but fundamentals like dynamic range and color depth take a backseat compared to larger sensors.

By contrast, the Sigma DP2 Merrill features a 24x16mm APS-C sized sensor with Foveon X3 technology. This unique stacked sensor design captures full color information at every pixel layer, producing richer detail and exceptional color fidelity at 15MP effective resolution. Despite cumbersome high ISO noise and limited dynamic range compared to modern CMOS sensors, the DP2 Merrill’s image quality - particularly in well-lit conditions - is stellar.

My lab testing confirmed that Sigma’s advantage shines in controlled lighting and landscape work, where clarity and tonal gradation matter most. Olympus’s sensor, however, wields flexibility and speed, better suited to everyday versatility and fast action.

LCD Screen and User Interface: Touch vs Tactility

The Olympus 1s houses a bright, tilting 3-inch touchscreen LCD with 1.04 million dots - making it a joy to operate for composing awkward angles or navigating menus swiftly. Its touch autofocus simplifies focus point selection, and the interface feels pleasantly intuitive. The addition of an EVF means relying less on the LCD in bright conditions.

Sigma’s DP2 Merrill, with a fixed 3-inch LCD at 920k dots, offers a sturdy viewing platform but no touchscreen or live autofocus aids. Its menu navigation depends on physical buttons alone, which slows workflow when making exposure or white balance adjustments. The absence of an EVF often forces relying on the LCD outdoors, which can hamper shooting speed and accuracy.

For street shooters who prefer a quiet, no-frills camera, Sigma’s interface may feel more authentic but less convenient for active shooting. Olympus clearly wins on flexibility and ease of use.

Autofocus and Performance: Speed vs Deliberation

Hands-on autofocus experience is where these two cameras diverge in usability.

Olympus’s Stylus 1s uses a contrast-detection AF system with 35 focus points and face detection - offering good tracking accuracy in daylight and moderate low light. Continuous AF works reliably up to its 7 fps burst shooting mode, which is impressive for a camera in its class. This responsiveness is a boon for wildlife and sports photographers who need fast capture without bulky lenses.

The Sigma DP2 Merrill, in stark contrast, has no autofocus systems beyond basic manual focus. No continuous or tracking AF, no face or eye detection, and no live view AF assist. This limitation makes Sigma’s camera best suited for intentional, slow, deliberate shooting - landscapes, portraits in controlled environments, or still life. Attempting fast action or wildlife shots is impractical.

To put it bluntly, Olympus is the faster, more versatile capture tool, while Sigma demands patience and skill.

Lens and Optical Performance: Zoom Flexibility vs Prime Sharpness

A significant difference lies in lens design. The Olympus 1s sports a fixed 28-300mm equivalent f/2.8 zoom - a very impressive range covering wide angle to telephoto, all at a constant bright aperture.

This versatility means you’re carrying one camera that can pivot from sweeping landscapes to distant wildlife easily. Optical image stabilization works well in combination with this lens, smoothing handheld shots at telephoto lengths.

On the other hand, the Sigma DP2 Merrill commits to a single 50mm f/2.8 lens (75mm equivalent on APS-C, considering its 1.5x crop factor). This prime lens focuses on sharpness and minimal distortion. The optic is undeniably superb for portraits and detail-rich photography but lacks the flexibility of a zoom.

For example, macro photography at close distances is simplified on Olympus due to a minimum focusing distance of 5cm, while Sigma offers no macro-specific functionality. In practice, this favors the Olympus for event or travel shooting, while Sigma appeals to image quality purists with a preference for prime optics.

Real-World Imaging: The Proof Is in the Photos

From my field tests spanning portrait, landscape, and urban shooting, both cameras produced characterful images with distinct personalities.

Olympus Stylus 1s excels at portraiture with its eye detection AF and natural-looking skin tones. The zoom lens creates a pleasant bokeh background at telephoto focal lengths, helping subjects stand out in environmental portraits. Its dynamic range is moderate but acceptable for typical outdoor conditions.

The Sigma DP2 Merrill impresses with extraordinary sharpness and color rendition. Its Foveon sensor produces files with a liquid texture and deep color saturation that’s hard to replicate in cameras with conventional sensors. However, fine noise becomes intrusive beyond ISO 800, limiting low-light usability.

Night time and astro photography are not the strong suits of either - Olympus’s small sensor struggles with noise, while Sigma lacks high ISO support altogether.

Video Capabilities: Basic vs Limited

Though both cameras primarily focus on stills, Olympus 1s offers full HD 1080p video at 30 fps, featuring optical image stabilization, which smooths handheld footage. Video controls include exposure compensation and manual modes, making it adequate for casual videography.

The Sigma DP2 Merrill, meanwhile, offers paltry VGA video at best (640x480), intended more as a novelty than a serious video tool. Audio input is nonexistent on both, but Olympus’s HDMI and USB 2.0 ports support data transfer and tethered shooting, enhancing workflow options.

Video shooters will find the Olympus 1s substantially more useful.

Battery Life and Storage: Longevity vs Basic

Battery performance plays a crucial role for travel and outdoor photography. Olympus claims 450 shots per charge, which aligns well with my experience - enough for a full day of shooting.

Sigma’s battery life specifications are unclear, and users report needing frequent recharges or carrying spares for extended sessions. Storage-wise, Olympus supports SD, SDHC, and SDXC cards in a single slot, while Sigma’s storage specs are unspecified but similarly single-slot.

For reliability in fieldwork or extended shoots, Olympus gains the edge.

Toughness and Weather Sealing: Neither Built for Battle

Neither camera is weather sealed or shockproof, limiting outdoor ruggedness. The Olympus Stylus 1s’s SLR-style body feels more robust and ergonomic for rough conditions, but you’ll need to protect both cameras from rain and dust.

Connectivity and Extras: Modernity vs Classic

Olympus packs built-in Wi-Fi for wireless image transfer and remote control - useful for travel photographers and social sharers. Sigma DP2 Merrill supports no wireless connectivity, highlighting its generation gap and niche usage.

Both cameras feature USB 2.0 ports, but only Olympus offers an HDMI output, which aids multimedia workflows.
