Olympus SZ-11 vs Sigma DP2 Merrill: A Deep Dive into Contrasting Compact Cameras

In the world of compact cameras, options span a dizzying range of sensor sizes, zoom ranges, and feature sets. As someone fortunate to have tested thousands of cameras over the years - from league-leading DSLRs to innovative compacts - I'm always excited to explore how different designs serve different photographic ambitions. Today, I’m pitting two very different cameras head-to-head: the Olympus SZ-11, a small-sensor superzoom compact from 2011, and the Sigma DP2 Merrill, a large-sensor fixed-lens compact launched in 2012.

These two cameras couldn’t be more different in philosophy, target audience, and feature set. The SZ-11 aims for versatile casual shooting with long zoom, while the DP2 Merrill is designed for image quality enthusiasts seeking large-sensor performance in a pocketable body. Let’s unpack their specifications, performance, and real-world usability - through my comprehensive testing - to help you find which one, if either, suits your photography style.

A Tale of Two Bodies: Size, Handling, and Build

The first and most obvious contrast between the cameras is their physical dimensions and design approach.

Olympus SZ-11: Lightweight and Functional

At 106x69x40mm and just 226 grams, the Olympus SZ-11 is a compact and lightweight camera that easily slips into a jacket pocket or handbag. Its ergonomics feel tailored for casual users:

• A simple, fixed 3-inch TFT LCD with 460k dots, no touchscreen.
• Pleasant grip despite the lightweight plastic body.
• No viewfinder means framing relies solely on the LCD.
• Reasonably spaced buttons, albeit not illuminated or particularly customizable.

The Olympus’s compactness and low weight impressed me during street photography and travel outings - comfortably unobtrusive when you want to snap quick candid moments or zoom into distant subjects.

Sigma DP2 Merrill: Bulky, Serious Craftsmanship

On the other hand, the Sigma DP2 Merrill weighs 330g and measures 122x67x59mm, noticeably chunkier but still pocketable for enthusiasts willing to trade portability for image quality and control. Notable points include:

• Fixed 3-inch LCD with 920k dots - bright, sharp, and with excellent color rendering.
• Sturdier build, heavier metal elements, giving a professional feel.
• Minimalist layout with few buttons, relying heavily on manual control.
• No viewfinder included; photographer composes solely with the back screen.

While I found the DP2 Merrill less suited for grabbing fleeting street moments due to its size, it felt like an artist’s tool when shooting portraits or landscapes, inviting deliberation.

Control, Interface, and Usability: Which Design Speaks Your Language?

From my hands-on experience, control layouts influence shooting spontaneity far more than sensor size or pixel count alone.

The Olympus SZ-11 is decidedly aimed at simple operation:

• No manual focus or exposure modes, instead relying on full auto or scene modes.
• Continuous AF and face detection are present but basic and slow.
• Limited exposure compensation and no RAW support.
• Zoom control is handy with a dedicated toggle around the shutter button.

In practical terms, I felt the SZ-11 excellent for casual travel snapshots or wildlife on the cheap, but it quickly ran out of steam under demanding lighting or artistic intent.

The Sigma DP2 Merrill, conversely, is a manual photographer’s darling:

• Aperture priority, shutter priority, and full manual exposure modes.
• Manual focus ring on the fixed lens, allowing precise control for portraits or macros.
• Custom white balance and image format choices including RAW.
• Slow autofocus system and no continuous AF or face detection - so patience is essential.

While taking portraits or architectural details, I appreciated how deliberate shooting with the DP2 Merrill forced me to slow down and craft each frame carefully. The lack of autofocus speed is a sacrifice for superior image quality, as I’ll discuss more below.

Sensor and Image Quality: The Heart of the Matter

Knowing these cameras’ shared compact category masks fundamental differences in sensor technology and resultant image quality.

Olympus SZ-11’s Small CCD Sensor

• Type: 1/2.3" CCD, 14MP resolution.
• Sensor area: 28.07 mm², with anti-aliasing filter.
• Max ISO of 1600.
• Limited dynamic range and color depth.
• Slight image noise creeping in at ISO 800 and above.

This sensor class is common in superzoom compacts aiming for affordability and zoom versatility rather than top-tier image quality. The CCD technology provides decent color but tends to struggle in low light or high contrast scenes.

Sigma DP2 Merrill’s APS-C Foveon X3 Sensor

• APS-C sized (24x16mm), 15MP effectively (with 4656x3104 output), but because of Foveon design, pixel count equates differently.
• Sensor area about fourteen times larger than the Olympus.
• Max ISO 6400, with far superior control of noise at moderate ISOs.
• Unique three-layer sensor capturing red, green, blue at each pixel location for extraordinary color fidelity and detail.
• No anti-aliasing filter, which boosts sharpness and micro-contrast.

From my extensive lab testing using standardized test charts and real outdoor shooting, the Sigma’s sensor delivers stunningly rich colors, razor-sharp detail, and a notable boost in low light handling compared to the Olympus. The difference is akin to night and day - this large sensor approach clearly pays dividends if image quality is your primary concern.

Viewing and Composing: LCD Quality, Viewfinders, and Live View

Neither camera sports an optical or electronic viewfinder, which some enthusiasts may miss for stability and framing precision.

The SZ-11’s LCD, while average resolution and panel quality, is perfectly adequate outdoors in bright sunlight thanks to moderate reflectance and anti-glare coatings. However, its limited resolution means fine detail and critical focus checking are challenging.

The DP2 Merrill’s LCD offers more real estate with nearly double the resolution, enabling careful framing and pixel-level sharpness assessment directly on-screen. This is crucial given the manual focusing workflow, where minute adjustments matter.

For long shooting sessions, I found the Olympus’s lighter weight less tiring, but for deliberate compositions - portraits or landscapes - the Sigma’s crisp LCD was invaluable.

Real-World Photography Performance Across Genres

Let’s move from specs to action. I put both cameras through diverse scenarios reflecting their typical use cases.

Portrait Photography

Portrait shots demand natural skin tone reproduction, accurate exposure, pleasing bokeh, and ideally subject tracking or eye detection.

• Olympus SZ-11: Face detection works but tends to miss subjects in complex light or quickly moving scenes. The small sensor and lens aperture range (f/3.0-6.9) deliver shallow but restrained bokeh that can look plasticky at wide apertures. Skin tones rendered adequately but not great in mixed lighting.

• Sigma DP2 Merrill: With its fast f/2.8, fixed 50mm lens and large APS-C Foveon sensor, the DP2 Merrill produces profoundly natural skin tones and silky smooth background blur, adding 3D pop to portraits. Manual focus allows precise eye-level focus. No eye-detection AF means more deliberate shooting.

Landscape Photography

Dynamic range, sharpness, resolution, and weather sealing factor prominently here.

• Olympus SZ-11: Dynamic range is limited; highlights may clip and shadows block up due to sensor constraints. Image resolution (14MP) is decent but struggles to hold fine detail at pixel-peeping level. No weather sealing restricts rugged outdoor use.

• Sigma DP2 Merrill: The camera shines here with wide tonal range, excellent shadow recovery, and superb micro-contrast. The lens’s sharpness corner to corner is remarkable. No environmental sealing, though, which discourages use in rough weather.

Wildlife and Sports

Long telephoto reach and fast autofocus are king contenders here.

• Olympus SZ-11: The 20x zoom (25-500mm equivalent) is a major asset for wildlife trips. However, autofocus is slow and hunting-prone under low light or contrast, which hurts action shots. Burst mode of 7fps is decent but buffered for a few frames.

• Sigma DP2 Merrill: Fixed 50mm focal length and slow autofocus mean this is a non-starter for wildlife or sports. Burst rate is just 4fps with limited buffer. Not designed for moving subjects.

Street Photography

Discreetness, responsiveness, and low-light capability are priorities.

• Olympus SZ-11: Compact, but zoom lens and slower AF reduce responsiveness. No silent shutter or high ISO optimization hinders low light work. However, the full auto modes simplify shooting on the go.

• Sigma DP2 Merrill: Bulky by street standards and slow shooting cadence makes candid shots difficult. But excellent image quality and manual controls appeal to deliberate, contemplative street shooters.

Macro Photography

Close focusing, stabilization, and sharpness matter here.

• Olympus SZ-11: Close focus to 1 cm and built-in sensor-shift stabilization helps capture tiny subjects without blur.

• Sigma DP2 Merrill: No dedicated macro mode or close focus range specified; relies on manual focus precision. No image stabilization, which demands tripod use.

Night and Astro Photography

High ISO performance and long exposure options are essential.

• Olympus SZ-11: Max ISO 1600 and shutter speed range 4s to 1/2000s. High noise beyond ISO 400 makes night shooting noisy; no bulb mode.

• Sigma DP2 Merrill: Max ISO 6400 with cleaner output. Supports longer exposures and full manual mode. Ideal for starry skies when tripod-mounted.

Video

Neither camera leads in video.

• Olympus SZ-11: Records HD 720p at 30fps but in Motion JPEG format limiting quality and file sizes. No microphone input or stabilization during video.

• Sigma DP2 Merrill: VGA video only, hardly usable for modern needs.

Travel Photography

Versatility, battery life, and handling impact usability during extended trips.

• Olympus SZ-11: Excellent zoom versatility and lightweight body ideal for travel snapshots. Battery life rated at 200 shots - not great, but user-replaceable batteries help.

• Sigma DP2 Merrill: Exceptional image quality but bulkier and no zoom limits framing options. Battery life data not specified but known to be limited due to large sensor and screen.
