Samsung ST700 vs Sigma DP2

Samsung ST700 vs. Sigma DP2: A Hands-On Comparison of Two Compact Cameras from Different Worlds

Choosing the right compact camera can be a head-scratcher, especially when options come from entirely different design philosophies and performance classes. Today, we'll dive deep into two intriguing models from the early 2010s: the Samsung ST700, a budget-minded ultracompact with some user-friendly bells and whistles, and the Sigma DP2, a large-sensor fixed-lens enthusiast compact that’s essentially a pocketable technical marvel. Both carry their own baggage and bright spots, but who comes out on top for various photography needs? Read on for my candid, experience-based comparison.

Size matters: The ST700 is notably slimmer, while the DP2’s chunkier body hints at its bigger sensor and more complex internals.

First Impressions: Ergonomics and Build Quality

As someone who’s held and tested thousands of cameras over the years, ergonomics often make or break the shooting experience - especially in compacts.

The Samsung ST700 is a svelte ultracompact measuring just 99x55x20mm. It’s perfect if you’re a cheapskate or minimalist who needs a decent point-and-shoot to stuff in a pocket or purse without a fuss. The chassis feels light, but that also means it’s not built like a tank; no weather sealing or ruggedness to speak of. For everyday casual use, it passes, but it won’t survive much beyond indoor or fair-weather shooting.

By contrast, the Sigma DP2 is chunkier at 113x60x56mm and weighs around 280g, reflecting that it’s packing an APS-C sized sensor under the hood. It’s not bulky per se but definitely not a pocket-fit. Despite lacking weather sealing like the ST700, its sturdy feel and controls cater to more serious image makers. Expect to hold it deliberately, with clubs for thumbs on the back and grip on the front.

Image Quality: Sensor Showdown

Here’s where the gulf truly opens up. The ST700 uses a typical 1/2.3" CCD sensor with 16MP resolution, while the Sigma DP2 sports a unique 5MP APS-C Foveon X3 sensor. Let me explain how that shapes their output.

The Samsung’s CCD sensor is small - just 6.16x4.62mm, about 28mm² area - which means higher noise at ISO and challenges with dynamic range. The images are detailed by compact camera standards but fall short in color accuracy, especially in complex lighting. Skin tones can look a little plasticky, and low light shots generally stumble with digital noise.

For the Sigma, the Foveon X3 sensor is more of a purist's dream. While it only records 5MP per output image dimensionally, the three layers capture RGB color data at every pixel location, delivering superior color fidelity and sharpness. Plus, with a much larger sensor size (20.7x13.8mm, ~286mm²), the dynamic range is significantly improved, rendering shadows and highlights with more detail, albeit with a need to expose carefully due to limited ISO range (200-3200 native).

Consider the difference - Sigma’s sensor is nearly 10x the surface area of Samsung’s, a giant leap in image capturing potential.

In practical terms: the DP2 outputs images with richer, more natural colors and better low-light character. Meanwhile, the ST700 delivers acceptable daylight shots when it stays ISO 100-200, but struggles when the sun sets or indoors.

Focusing and Control: Manual vs. Automatic

Since I test cameras by shooting under diverse real-world conditions - from sun-drenched outdoor scenes to tricky interiors - autofocus and control ergonomics are critical for me.

The Samsung ST700 offers no manual focus and limited autofocus functionality (a mere center-weighted metering and basic AF). It lacks touch autofocus or face/eye detection features. What you get here is a simple AF system that sometimes misses quickly moving subjects or fine-focus details (like in macro or portrait shots). For casual shooting or static subjects, it’s passable but far from impressive.

In contrast, the Sigma DP2 demands you take a more traditional approach. It exclusively features manual focus, controlled via a small focus ring on its fixed 41mm equivalent lens (at 1.7x crop factor). Autofocus is limited to single-servo contrast detection, which can be sluggish, and there’s no continuous AF tracking. Manual focusing precision, however, rewards patience and skill, especially with the camera's live view function allowing magnified viewing.

For photographers who like to nail focus themselves - macro shooters, or portraitists who want critical control over eyes and lashes - the DP2 shines in this manual realm. Conversely, if you prefer a camera that decides focus for you and speeds through snaps, the ST700 is more your style.

Handling and User Interface

One of the first things I do when testing cameras is evaluate their button layout, menu system, and overall usability rhythms. Winners here are ones that balance quick access and intuitive sequencing.

On the Samsung, ergonomics favor simplicity: a 3” fixed touchscreen (230k dots) makes menu navigation a breeze for newbies, though the screen is on the dim side and difficult to read in bright sunlight. The touchscreen adds a layer of ease missing on DP2. However, I found the lack of more advanced controls frustrating for exposure, ISO, or focus – it’s a point-and-shoot through and through.

The Sigma’s screen is smaller at 2.5” and not touch-sensitive, making menu navigation a bit slower. Thankfully, it is thoughtfully laid out towards manual settings - shutter priority, aperture priority, manual exposure with exposure compensation - and a two or ten-second self-timer is available (something the Samsung lacks). For photographers wanting a tactile, purposeful interface with real control (and willing to spend time fiddling), DP2 wins hands down.

Samsung’s touchscreen is easy but basic; Sigma’s interface is more technical yet more flexible for manual tweaking.

Lens Versatility and Performance

Both cameras come with fixed lenses, which means understanding how they fare in different shooting genres is essential.

• Samsung ST700: Lacks lens focal details but has a focal length multiplier of 5.8x, indicating a superzoom capability in a tiny body. This makes it versatile for travel or casual snapshots, covering wide angles to moderate telephoto.

• Sigma DP2: Fixed at 41mm (1x crop), meaning no zoom, just a moderate normal field of view that’s terrific for portraits and street photography but less flexible for wildlife or distant subjects.

If you need reach for wildlife or sports, neither is ideal, but Samsung’s zoom range outclasses Sigma’s fixed normal lens for all-around convenience. The DP2’s lens, however, offers very high sharpness and pleasing bokeh at its fixed aperture, rewarding slow, deliberate compositions.

Photography Disciplines Compared

Let’s map these cameras onto popular photography use cases to find their sweet spots or pain points.

Portrait Photography

Sigma’s Foveon sensor renders remarkably accurate skin tones and subtle gradations, making it a favorite for portraits, albeit with manual focus demands. The 41mm field of view is flattering and natural. The ST700, while automatic and user-friendly, often flattens or oversaturates faces under mixed lighting, giving a more snapshot feel.

Landscape Photography

The DP2’s large sensor and dynamic range easily win here. You’ll get images rich in detail, with minimal noise, and wider latitude for editing. The Samsung’s tiny sensor cannot compete in resolution nor dynamic range, though its zoom helps framing distant landscape features.

Wildlife and Sports

Neither camera is designed for high-speed action. The Samsung’s autofocus and zoom offer decent capturing abilities at distance but poor tracking performance. The Sigma suffers from slow contrast detection AF and low burst speed (3fps), making it impractical for wildlife or sports beyond still scenes.

Street Photography

The Sigma DP2, with its discreet profile, moderate lens, and excellent image quality, is ideal for contemplative street shooters who can slow down and compose. Meanwhile, the Samsung’s pocketability and ease-of-use make it convenient for spontaneous street snaps but image quality during low light will disappoint.

Macro Photography

Neither camera excels macro. Lack of specialized macro modes or lens close-focusing range on the ST700 limits macro capabilities, while Sigma’s fixed normal lens and manual focus enable close-ups only with effort and patience.

Night and Astro Photography

With no built-in stabilization and limited high ISO on both, night or astro photography is challenging. The DP2 handles noise better but lacks long exposure modes beyond 15s shutter speed. The ST700 maxes out at 2 seconds, limiting low-light creative flexibility.

Video Capabilities

Samsung manages 720p HD video, a modest offering good for casual clips. Sigma’s video is limited to 320x240, more of a novelty than practical. Neither supports microphone inputs or advanced stabilization, so video enthusiasts should look elsewhere.

Travel Photography

Samsung’s lightweight body, zoom versatility, and touchscreen offer convenience for travel snapshots and slip-in-the-pocket moments. Sigma’s superior image quality is compelling, but the size, manual focus, and slower operation reduce versatility when time and mobility matter.

Professional Use

Sigma’s RAW support and manual control modes align with professional workflows craving high-quality stills and post-processing latitude. Samsung’s JPEG-only output and lack of manual exposure fall short here.

Technical Analysis: Diving Into the Details

I’ve mentioned practical impressions, but let’s back it up with some specs and real metrics.

• Sensor & Image Quality: Sigma DP2’s large APS-C Foveon sensor delivers much better color depth and dynamic range. ST700’s 1/2.3" CCD is typical of compact cameras but cannot match the tonal subtleties or noise control.

• Autofocus: Neither offers advanced AF tracking or face/eye detection. Sigma’s manual focus is precise but slow; Samsung’s autofocus is basic and limited.

• Build & Weather Resistance: Both lack environmental protection, a compromise expected for their categories.

• Ergonomics: Samsung’s touchscreen is user-friendly but lacks advanced controls. Sigma provides more manual override, but the UI can feel dated and slow.

• Lens Compatibility: Fixed lenses limit both. Samsung’s zoom lens provides flexibility; Sigma’s prime lens offers quality at the expense of versatility.

• Battery Life & Storage: Details unlisted for battery on either, but both take SD cards (Sigma explicitly). Neither supports dual slots or extended storage options.

• Connectivity: No Wi-Fi, Bluetooth, or HDMI ports. Samsung lacks USB entirely; Sigma offers USB 2.0 for data transfer.

• Price to Performance: At launch, Samsung’s $280 price targeted casual buyers wanting simple point-and-shoot convenience. Sigma at $650 aims at serious enthusiasts valuing image quality over speed or zoom.

Real-World Sample Images Speak
