Comparing the Samsung ST80 vs Sigma DP1s: Which Compact Camera Suits Your Photography?

In the evolving world of compact cameras, two models with quite different approaches stand out from the early 2010s crowd: Samsung’s ST80, a sleek ultracompact point-and-shoot, and Sigma’s DP1s, a niche large sensor compact celebrated for image quality. Though they debuted close in time - with Samsung’s ST80 announced in January 2010 and Sigma’s DP1s arriving in October 2009 - the design philosophies and performance priorities behind each differ sharply.

I’ve spent years testing cameras across genres and price points, so let’s peel back the layers on these two to see which one truly delivers where it matters, and uncover their respective strengths and compromises.

First Impressions: Size, Ergonomics, and Build

The physical handling of a camera is often overlooked before purchase, yet it profoundly impacts the shooting experience. Personally, I prioritize ergonomics alongside performance, so here’s how these two stack up.

The Samsung ST80 is a textbook ultracompact - small, light (only 118 grams), and pocketable. Its body measures just 92x55x19 mm, fitting easily into a jacket pocket or small bag. This naturally appeals to street and travel photographers who want minimal bulk.

On the other hand, the Sigma DP1s is noticeably chunkier and heavier, coming in at 270 grams with dimensions around 109x60x31 mm. It doesn’t slip so effortlessly into pockets, demanding more deliberate packing. The weight and size stem from its larger APS-C sensor and fixed, premium lens assembly.

Top-down, the ergonomics reveal Samsung’s design focused on simplicity, with a touch-enabled 3-inch LCD dominating the back, and just enough physical controls to keep the interface straightforward. Meanwhile, Sigma’s layout is minimalistic but less intuitive for quick adjustments since it lacks a touchscreen and relies on more traditional buttons and rotary controls.

For photographers who want grab-and-go convenience paired with touchscreen fun, the ST80 feels modern and accessible. If you’re comfortable with manual controls and can tolerate the extra heft for image quality gains, DP1s aims at a more deliberate photographic experience.

Image Quality Foundations: Sensor Size and Technology

Now we get to a crucial differentiation point: sensor technology and its impact on image quality.

The Samsung ST80 utilizes a 1/2.3" CCD sensor - a typical small sensor for compact cameras of its era. It packs about 14 megapixels at a physical sensor area of roughly 27.7 mm². This sensor is optimized for convenience and offers fairly decent resolution but is limited in control over noise and dynamic range due to its size.

By contrast, the Sigma DP1s employs a 20.7x13.8 mm APS-C sized Foveon X3 CMOS sensor, covering a sensor area around 285.7 mm² - over ten times bigger than Samsung’s. Foveon technology captures color differently by sampling red, green, and blue at every pixel location, potentially resulting in richer color rendition and sharper images at lower megapixel counts (around 5 megapixels native, but with a unique layered color resolution).

From my hands-on testing, the DP1s’s sensor produces images with noticeably richer tones and finer detail than typical compact cameras, especially in good light. However, the downside is that it tops out at ISO 800 native and shows noise sooner in low light than larger modern sensors.

Samsung’s CCD, while adequate for casual use, clearly can’t compete in image quality terms due to sensor size and underlying tech. Fine detail, dynamic range, and noise control all favor the Sigma. So if your priority is the quality of prints or post-processing latitude, the DP1s steps up significantly.

User Interface: Screens and Shooting Ergonomics

How a camera communicates information and how you control it are vital for workflow fluidity.

The Samsung ST80 stands out with its bright 3-inch touchscreen, although its 230k-dot resolution feels a bit low by today’s standards. Still, the touch interface aids quick setting changes and metering adjustments, ushering in some user friendliness absent from the DP1s.

The Sigma DP1s, meanwhile, offers a smaller 2.5-inch fixed LCD with the same resolution but lacks touch capability. This makes menu navigation slower and less intuitive, particularly for newcomers. Yet, the physical buttons provide tactile feedback, favored by those who don’t like finger-swiping or want precise button presses, especially in cold weather or with gloves.

Neither camera features any kind of viewfinder, electronic or optical, so reliance on the rear screen for composing in bright light is a shared challenge - though the DP1s’s slightly bigger screen helps.

Autofocus and Shooting Responsiveness

Autofocus (AF) performance is critical whether you’re shooting sports, wildlife, portraits, or casual snapshots.

The ST80 uses contrast-detection AF with touch-to-focus, central AF area selection, and face detection on board. However, note that continuous AF and tracking features are absent, limiting usability with moving subjects.

The DP1s employs contrast-detection AF as well but lacks face detection altogether, sticking to a center-weighted AF point. It’s a manual-focus-friendly camera but doesn’t provide fast or predictable autofocus for action photography.

Neither camera supports burst shooting or fast continuous AF, capping their appeal for sports and wildlife photographers who demand rapid frame rates and tracking precision.

In practical use, I found the ST80’s autofocus quicker and more reliable for general use, aided by face detection. The DP1s feels more deliberate and requires patience with manual focus, ideal for static subjects or landscapes, but frustrating for anything fast-moving.

Lens and Focal Range Differences

Lens quality, flexibility, and aperture shape creative options and image style.

The Samsung ST80 features a fixed zoom lens with a 35-105 mm equivalent focal length and an aperture range of f/3.3-5.5. This covers classic short-telephoto portrait lengths and moderate zoom but isn’t especially sharp wide open. Optical image stabilization is included, beneficial for handheld shots at slower shutter speeds.

Sigma’s DP1s comes with a fixed 28 mm equivalent prime lens (wide-angle) with a moderate aperture (details unspecified) but known for sharpness and minimized distortion. There’s no zoom but the lens’s image quality often outperforms many compacts’ zooms. Absence of stabilization means shooting steady or with a tripod is recommended.

For portraits or telephoto reach, the ST80 offers more flexibility. For landscapes, architecture, and street photography where wide-angle clarity matters, the DP1s excels.

Performance Across Photography Genres

Let’s break down how these cameras perform in key photographic disciplines - you’ll find my real-world thoughts here particularly useful.

Portrait Photography

• ST80: Face detection AF helps nail focus on eyes and faces, producing pleasing skin tones courtesy of the small sensor’s moderate noise. The zoom lens aids framing expressions more easily, though bokeh is constrained by the small sensor and aperture maxes.

• DP1s: Larger sensor delivers richer skin tones and natural depth but fixed wide lens limits framing options (you’re shooting wider, requiring cropping or subject placement skill). Manual focus means slower capture, but with care you get exceptional color fidelity.

If portraits with easy framing and quick autofocus are your priority, I recommend the ST80. For studio or deliberate portraits emphasizing color finesse, go with the DP1s, provided you’re comfortable with manual focus.

Landscape Photography

Larger sensors and sharp wide lenses rule landscapes.

• DP1s: APS-C Foveon sensor and 28mm sharp lens are ideally suited. The expansive dynamic range and color depth here pay off, capturing intricate textures and subtle lighting gradations impressively.

• ST80: Smaller sensor limits dynamic range; zoom lens flexibility helps vary compositions but image quality shows compression in detail on closer inspection.

If your landscapes require ultimate image quality, the DP1s is the clear winner.

Wildlife Photography

Both fall short here.

• ST80: Limited zoom and no continuous or tracking AF limit usefulness on moving animals.

• DP1s: Manual focus, fixed wide lens, and slow AF make it impractical.

Neither camera is suitable for serious wildlife shooters.

Sports Photography

Fast AF and frame rates needed - both cameras lack.

Street Photography

• ST80: Ultra compact, touchscreen controls, and zoom versatility make it a good grab-and-go choice.

• DP1s: Larger size and manual focus slow down quick street snaps, but image quality is superb when you have time to compose.

Casual street shooters will prefer the ST80 for subtlety and ease of use.

Macro Photography

• ST80: Macro focus down to 5cm coupled with stabilization help handheld close-up shots.

• DP1s: No dedicated macro mode or close focus distance; manual focus precision can work but needs tripod support.

Macro enthusiasts favor the ST80.

Night and Astrophotography

• DP1s: Limited ISO range (max 800) restricts night shooting, but low noise and longer shutter speeds possible.

• ST80: Higher max ISO (4800) but small sensor noise compromises quality.

For astrophotography, neither is ideal, but the DP1s’s image quality edge makes it my preferred pick despite ISO limits.

Video and Multimedia

• ST80: Offers 720p HD video at 30fps with Motion JPEG format, reasonable for casual clips.

• DP1s: No video capability.

So if video is on your checklist, the ST80 is the camera to have.

Travel and Everyday Use

• ST80’s compactness, zoom range, image stabilization, and video capabilities make it the travel-friendly choice.

• DP1s delivers image quality but demands a more deliberate, slower shooting style, making it less versatile on fast-paced trips.

Professional Workflow Insight

For professionals, raw support, file formats, and integration matter.

• DP1s supports raw capture, allowing flexibility in post-processing and better-quality prints.

• ST80 offers JPEG-only capture, limiting post-production latitude.

The Sigma’s Foveon sensor files require specialized software, but can reward professionals with exceptional images. However, Sigma’s slower interface and lack of autofocus features reduce efficiency for commercial work.
