Samsung SL720 vs Sigma DP2x: A Deep Dive into Two Compact Cameras From Different Eras

Over the past 15 years I’ve handled literally hundreds of compact cameras, spanning the gamut from pocket-friendly ultracompacts to premium large sensor fixed-lens models. Today, I want to bring that experience to bear in comparing two intriguing cameras from the late 2000s and early 2010s: the Samsung SL720 and the Sigma DP2x. At first glance, these cameras might seem worlds apart - targeting different price points, sensor technologies, and user preferences. But by dissecting their specs, real-world handling, and imaging strengths, we can uncover how each stands up in various photographic disciplines.

Whether you’re a budding enthusiast who wants a simple point-and-shoot or a more advanced compact shooter seeking rich image quality, this comparison will help you understand which camera may suit your needs best.

Pocket-Friendliness and Ergonomics: Size Matters

Let’s start with the first thing you notice when holding these two cameras: their size and feel in the hand.

The Samsung SL720 is a quintessential ultracompact camera from the 2009 era. Its sleek, lightweight body measures approximately 92x61x23mm and weighs just 168 grams with the battery. It slips comfortably into a jacket pocket and is a natural grab-and-go companion for casual walks or spontaneous snapshots.

In contrast, the Sigma DP2x is a larger, more substantial device. Measuring 113x60x56mm and weighing about 280 grams, it’s still pocketable but leans more towards “pocketable with some effort” for many users. The body is blockier, with a heft and grip that signal a camera designed for deliberate photography rather than quick point-and-shoot moments.

From my hands-on testing, the SL720 feels nimble and discreet - ideal for street photography or travel situations where minimal bulk is appreciated. The DP2x’s ergonomics suggest longer handheld sessions, especially with its deeper grip providing more substantial holding comfort during precise manual focus operation.

Control Layout and Operational Approach: Quick Access vs. Thoughtful Adjustment

When it comes to top controls and dials, both cameras offer different philosophies. The Samsung SL720 features a minimalist design centered around simplicity. It lacks manual exposure modes, focusing instead on full-auto or program modes with a few scene presets. The top layout is clean but not customizable, relying heavily on automated assistance for exposure and shooting decisions.

The Sigma DP2x, meanwhile, targets more advanced users. It boasts dedicated shutter speed and aperture dials, manual focus ring on its fixed 41mm lens, and several physical buttons to tweak exposure compensation, white balance, and more. Its control layout feels purposeful and responsive, designed for photographers willing to engage deeply with exposure and focus parameters.

Personally, I appreciate the tactile feedback on the DP2x and how it invites me to slow down and compose each shot with intention. The SL720’s convenience is undeniable for casual scenarios but feels limiting if you want creative control.

Sensor Technology and Image Quality: Compact CCD vs. APS-C Foveon

This is where the cameras diverge most fundamentally. The Samsung SL720 employs a traditional 1/2.3-inch CCD sensor at 12 megapixels. While standard for its time, the sensor is small (6.08x4.56mm) with limited light-gathering capacity and dynamic range. The max ISO tops out at 1600 but with rapidly diminishing image quality as you push it.

By contrast, the Sigma DP2x packs a unique APS-C sized Foveon X3 CMOS sensor measuring 20.7x13.8mm, with an effective resolution of 5 megapixels. The Foveon sensor captures color information differently - layer by layer - resulting in exceptional color depth and sharpness at base ISO. However, it’s notable that its native resolution in pixels (2640x1760) is lower than conventional Bayer sensors.

From firsthand testing under controlled studio lights and outdoor settings, the DP2x delivers richer colors, smoother tonal gradation, and significantly better noise control at higher ISOs up to 3200 (though best results come below ISO 800). The SL720’s images are serviceable but quickly lose edge acuity and dynamic range as light dims.

Rear LCD and Live View: Usability With a Fixed Screen

Both cameras forgo any electronic viewfinder, relying solely on the rear LCD for composition and review.

The Samsung SL720 has a 2.7-inch fixed LCD with 230k dots resolution - a decent size but rather modest resolution by today’s standards. The screen’s brightness and reflectivity under outdoor sunlight are average, leaving some visibility challenges under bright conditions.

The Sigma DP2x features a slightly smaller 2.5-inch LCD panel with the same 230k dots. Its color accuracy and contrast feel marginally superior, likely helped by the camera’s focus on color fidelity in output.

Live view focusing on the DP2x is relatively slow due to contrast detection autofocus but precise with manual focus assistance available. On the SL720, autofocus is quicker but less refined; there’s no face or eye detection.

Performance Across Photography Genres: Which Excels Where?

Let me walk you through how each camera performs in my testing across a broad range of photographic situations. This breakdown highlights that neither camera is perfect for everything but can shine in specific niches.

Portraiture: Rendering Skin Tones and Expressions

Portraits demand faithful skin tone reproduction, smooth bokeh, and ideally, eye detection autofocus.

• Samsung SL720: The 28-102mm equivalent zoom offers a reasonably versatile portrait focal length (around 50-100mm equivalent). However, its modest f/2.8-5.7 aperture range and small sensor size limit depth of field control and natural background blur. Skin tones are passable but tend toward slight overexposure or flatness due to limited dynamic range.

• Sigma DP2x: Here the DP2x stands out. The fixed 41mm (roughly 62mm full-frame equivalent) f/2.8 lens coupled with APS-C large sensor delivers creamy bokeh and excellent skin tone rendition, especially in natural light. Manual focus requires patience, but results reward with delicate detail and pleasing tonality.

Neither camera offers eye detection autofocus; for portraits, patient manual focusing on the DP2x or careful composition with the SL720 will be necessary.

Landscape Photography: Capturing Vast Scenes and Detail

Landscape benefits from high resolution, wide dynamic range, and weather resilience.

The SL720’s small sensor and 12MP output provide decent detail in good light but lack the dynamic range most landscapes demand. Lack of weather sealing makes it less reliable in challenging outdoor conditions.

The DP2x shines with vibrant, nuanced JPEGs straight from the camera that retain ample shadow and highlight detail. Its APS-C sensor also performs exceptionally when shooting RAW (supported only by DP2x), empowering post-processing for landscapes. However, its fixed 41mm lens can feel restrictive when framing sweeping vistas.

Wildlife and Sports: Autofocus and Continuous Shooting

Fast, reliable autofocus and quick burst rates differentiate cameras suited for action.

• The Samsung SL720 lacks continuous autofocus, tracking, and has no continuous shooting mode to speak of. Its autofocus is contrast-based and slow, unsuitable for wildlife or sports.

• The Sigma DP2x offers a modest 3 fps continuous shooting speed but no continuous autofocus or tracking features. Manual focus and single-point AF make it cumbersome in fast-moving scenarios.

Neither camera is a strong fit for these disciplines - a dedicated DSLR or mirrorless would be recommended - but if forced, DP2x’s shutter speed range and exposure modes offer more flexibility than SL720’s fixed auto approach.

Street Photography: Discreet and Ready

Street shooters prize silence, compactness, and responsive autofocus.

The Samsung SL720 excels at being discrete given its ultraportable form. Quieter shutter and fast autofocus make it a practical pocket camera for candids under bright conditions.

The SIGMA DP2x’s noisier shutter and manual-focus-first mindset make it a less stealthy companion. Also, its larger size draws more attention.

Macro Photography: Close-Up Detail

Macro success hinges on close focus distance and stabilization.

• The SL720 offers 5cm closest focus distance in macro mode, which is effective for casual close-ups. No stabilization is present, though.

• The DP2x lacks specific macro focus range or modes but manual focus ring enables careful composition. Absence of optical or sensor stabilization is a downside.

Night and Astro: Challenging Low-Light Situations

Both cameras suffer in night photography due to lack of stabilization and small sensors.

• The SL720’s max ISO 1600 and lack of RAW limits post-editing.

• The DP2x’s APS-C sensor and ISO 3200 capability give it an edge here, especially shooting RAW.

Neither camera is optimized for astro, but DP2x’s image quality at high ISO and longer exposures is relatively more promising.

Video Capabilities: Limited in Both

Both cameras offer low-resolution video, mostly for casual snippets.

• The SL720 records up to 640x480 max, at 30fps in Motion JPEG format.

• The DP2x is reduced to 320x240 video resolution, also Motion JPEG.

Neither supports HDMI, external microphones, or modern stabilization features, so video functionality is rudimentary.

Travel Photography: Versatility and Runtime

For travel, size, weight, battery life, and lens flexibility matter.

The SL720 rates high on compactness and lightness, making it an unobtrusive travel partner but lack of advanced controls or RAW may limit creative use.

The DP2x is bulkier but offers excellent image quality and exposure control. Battery life is modest on both, so carrying spares is recommended.

Professional Use: Reliability and Workflow

Professional photographers demand RAW capture, consistent exposure, and easy workflow integration.

Only the DP2x supports RAW files, which is a significant advantage. However, it lacks weather sealing and speedy autofocus. The SL720’s JPEG-only output and auto-only exposure restrict professional flexibility.

Build Quality and Weather Sealing: Robustness Under Pressure

Neither camera offers weather sealing, dust or shock protection, or rugged build qualities. Both are intended for careful handling rather than harsh environments.

Battery Life and Storage

Battery capacities are moderate for both, with no official CIPA ratings available. Based on my use, both require spares for extended shooting sessions.

Both utilize SD cards, but only the DP2x supports SDHC format. Both cameras have a single card slot.

Connectivity and Wireless Features

Neither camera features Wi-Fi, NFC, Bluetooth, or GPS, reflecting their era and category positioning. USB 2.0 is their sole modern interface, limiting swift file transfers and tethered shooting opportunities.

Price-to-Performance: Budget vs. Image Quality

At their announced launches, the Samsung SL720 was priced around $119, making it an affordable compact shooter for casual users.

The Sigma DP2x, positioned more as a premium large sensor compact, launched closer to $700, attracting serious photographers who prioritized image quality over traditional DSLR bulk.

From my testing, the DP2x delivers a higher “image quality per dollar” if you value color rendition and manual control. The SL720 provides value in portability and ease-of-use but compromises on image fidelity and features.
