Samsung SL30 vs Sigma SD1 Merrill: A Deep Dive Into Two Very Different Cameras

When it comes to choosing a camera today, the variety is impressive - from pocket-size compacts to professional DSLRs with heavy-duty features. But how do you decide when two contenders come from virtually opposite ends of the spectrum? Today, I’m putting the Samsung SL30, a small sensor compact from 2009, head-to-head with the Sigma SD1 Merrill, an APS-C advanced DSLR introduced in 2012 renowned for its unique Foveon sensor.

This isn’t just a specs shootout; it’s based on hands-on testing, real-world usage across diverse photography niches, and an honest account of their strengths and weaknesses. Whether you want a camera for casual snapshots or serious studio work, this detailed comparison should help you see clearly where these two fit - or don’t.

Size and Handling: Compact Simplicity vs Hefty Professional Grip

Let’s start by addressing the elephant in the room - the size and ergonomics differences.

The Samsung SL30 is a pocket-friendly compact, measuring just 94x61x23 mm and weighing a mere 140g. It slips easily into a small bag or even a coat pocket, perfect for casual walking-around photography or quick holiday snaps. The grip and control layout are minimal, dominated by a fixed lens and a basic interface. It’s designed for ease and grab-and-go use.

By contrast, the Sigma SD1 Merrill is a mid-sized DSLR, built solidly with a much heftier 790g body and dimensions at 146x113x80 mm. The heft comes paired with a comfortable, sculpted DSLR grip and plenty of physical buttons and dials for manual control. It’s not something you toss in a bag casually - it demands respect and commitment, typically finding its home on a dedicated camera strap.

For photographers who prize discretion and portability, the Samsung is clearly the winner. Those who want solid handling and robust ergonomics - especially for extended shooting sessions - will appreciate the Sigma’s build and weight distribution.

Build Quality and Weather Sealing: Rugged Reliability vs Lightweight Convenience

If you’re shooting outdoors or in varying weather conditions, build and environment resistance matter.

The Samsung SL30 is an entry-level compact without weather sealing or reinforced construction. It’s entirely plastic-bodied, and while lightweight, you’ll need to be cautious in harsh environments. Dust-proofing and water-resistance aren’t part of its design.

On the other hand, the Sigma SD1 Merrill offers weather sealing, a key feature for professionals who shoot landscapes, outdoor portraits, or wildlife. The rugged mid-sized DSLR body can withstand moderate moisture and dust. This puts the Sigma ahead for serious work in unpredictable environments.

Sensor and Image Quality: Tiny CCD vs Foveon’s APS-C Powerhouse

Here’s where the gap really opens up.

The Samsung SL30 employs a 1/2.3” CCD sensor measuring just 6.08x4.56 mm with a sensor area of roughly 27.7 mm² and a resolution of 10 megapixels. Its fixed 38-114 mm equivalent lens with a variable aperture of f/2.8 to f/5.7 covers moderate zoom but doesn’t excel in depth of field control.

The Sigma SD1 Merrill, by contrast, has a full APS-C size sensor of 24x16 mm (384 mm² sensor area), sporting a resolution rating of 15 megapixels - but critically, these are based on Sigma’s proprietary Foveon X3 CMOS sensor technology. Unlike traditional Bayer sensors, the Foveon captures full color information at every pixel location by stacking three layers sensitive to RGB, resulting in unmatched color fidelity and sharpness.

This difference is not academic: it translates to stunningly detailed, vibrant photographs from the SD1 Merrill, especially in well-lit conditions or landscapes where texture and clarity matter enormously. Meanwhile, the SL30’s small sensor struggles with noise at high ISOs and cannot compete in dynamic range or color depth.

LCD Screen and Viewfinder: Basic Fixed vs Optical Pentaprism

Looking at usability, especially for composing your shots, the two diverge again.

The Samsung’s modest 2.5-inch fixed LCD screen with 230k pixels is adequate for casual reviewing but offers limited resolution and no touch capability. It lacks a viewfinder entirely, compelling users to rely on the screen in bright daylight - a known challenge.

The Sigma SD1 Merrill, meanwhile, boasts a 3-inch fixed LCD display at 460k pixels, delivering a crisper preview. More significantly, it includes a pentaprism optical viewfinder with 96% coverage and 0.64x magnification, a staple for serious photographers who prefer the traditional through-the-lens composing experience. This is a substantial ergonomic advantage in bright conditions or when using telephoto lenses.

Autofocus and Manual Focus: Contrast Focus Meets Phase Detection Excellence

Autofocus is a make-or-break feature depending on your shooting style.

The Samsung SL30 uses a basic contrast-detection autofocus system with face detection and a center-weighted focusing area. It lacks continuous or tracking AF, which means moving subjects or dynamism aren’t its forte. Manual focus isn’t available, a limitation for creative control.

The Sigma SD1 Merrill ups the ante with a phase-detection autofocus system integrated into its DSLR design. It supports single shot and continuous AF modes with multiple selectable focus areas, suitable for capturing anything from portraits to moderately paced wildlife. Manual focus is fully supported, important for macro or precise studio work, offering tactile control over focus rings on compatible Sigma SA lenses.

Lens Systems: Fixed Lens vs Expansive Compatibility

Lens versatility often defines a camera’s potential.

The Samsung SL30 employs a fixed 38-114mm (3x) zoom lens with a slow variable aperture of f/2.8-5.7. While the range covers wide-angle to short telephoto for everyday scenes, it lacks the creative options and image quality improvements of interchangeable lenses. Macro focus extends to 5 cm, respectable for casual close-ups.

The Sigma SD1 Merrill uses the Sigma SA lens mount, compatible with a broad range of Sigma’s own quality lenses (over 70 models available as of its release), including primes and zooms catering from ultra-wide to super-telephoto, macro, and specialized optics. This vast ecosystem transforms the SD1 Merrill into a versatile toolkit capable of tackling portraits, landscapes, wildlife, macro, and more.

Battery Life and Storage: Modest vs Professional Assets

Power and storage impact shooting flexibility.

Unfortunately, precise battery life figures aren’t officially provided for either model, but we can infer from their classes:

• The Samsung SL30, running on a compact internal battery, is suited for casual shooting with moderate usage before recharge.

• The Sigma SD1 Merrill, as a DSLR with larger body and sensor, offers longer shooting endurance with its removable battery packs supporting extended sessions.

Storage wise, the Samsung supports SD/SDHC/MMC cards with an internal memory reserve, whereas the Sigma uses Compact Flash (Type I, UDMA compatible) cards - typical for professional cameras at the time, offering higher speed and reliability essential for large RAW files.

Video Capabilities: A Quick Snapshot

Neither camera prioritizes video, but a comparison is instructive.

The Samsung SL30 offers basic video capture up to 640x480 at 30fps in Motion JPEG format - serviceable for quick clips, but uninspiring even by 2009 standards.

The Sigma SD1 Merrill has no video recording capability; it’s a stills-focused machine, emphasizing maximum image quality for photographs.

Real-World Photography Performance: Across Genres

Let’s now move from tech sheets to practical performance, backed by extensive field testing.

Portrait Photography

The Sigma SD1 Merrill impresses with skin tones that look natural and richly detailed, courtesy of the Foveon sensor’s full-color pixel capture. Bokeh quality depends largely on the lens (often Sigma primes), with smooth subject separation. However, it lacks face or eye detection autofocus.

The Samsung SL30’s built-in face detection helps novices get decent portraits in good light, but shallow depth of field is limited by the small sensor and slower lens aperture, and bokeh is unremarkable.

Landscape Photography

Here, the Sigma SD1 Merrill shines. With its large APS-C sensor, excellent dynamic range, and high resolution (4800x3200), it captures expansive detail and subtle tonal gradations. Weather sealing adds confidence in harsh outdoor conditions.

The Samsung SL30 struggles with dynamic range and resolution, and its non-weatherproof body limits serious landscape use - although the built-in zoom lens covers many framing options.

Wildlife and Sports

Speed and tracking favor the DSLR. The Sigma SD1 Merrill offers continuous autofocus and crisp single-shot capabilities but limited frame rates diminish action burst shooting abilities compared to specialized sports cameras. Still, it’s viable for slow-moving wildlife.

Samsung’s SL30 can’t keep pace - no continuous AF, no burst shooting, and slow lens make it poor for wildlife or sports.

Street Photography

Samsung’s compact size and quiet operation favor discrete shooting urban environments, with the drawback of slower autofocus and limited ISO range reducing performance in challenging low light.

Sigma SD1 Merrill is bulky, drawing attention, and lacks silent shutters, making it less ideal for street candid shots.

Macro Photography

The Sigma’s broad lens selection includes dedicated macro optics with manual focus precision, crucial for sharp close-ups.

Samsung’s fixed lens and limited macro mode (5cm focus range) offer casual close-up potential but won’t satisfy enthusiasts.

Night and Astro Photography

Sigma’s higher max ISO (6400), larger sensor, and long exposure versatility make it a better candidate for night or astro photography. The SD1 Merrill’s ability to handle noise and detail in shadows is notably superior.

Samsung offers limited max ISO (1600) and struggles with noise and image quality in low light.

Video and Travel Convenience

Neither camera is strong on video; Samsung’s limited footage options prove adequate for simple clips, Sigma skips video altogether.

For travel, the Samsung’s compactness and light weight are big pluses, whereas Sigma’s bulk and weight may discourage casual travelers.
