Sigma DP1s vs Sony Cyber-shot DSC-W350: A Hands-On Comparison for Enthusiasts and Pros

When exploring compact cameras tailored for photography aficionados, especially those prioritizing image quality, ergonomics, and versatility, it’s easy to get overwhelmed by the numerous options available - even within the compact segment itself. Today, we dive into a detailed comparison between two rather distinct large/super compact cameras: the Sigma DP1s, an APS-C large sensor fixed-lens compact with the unique Foveon X3 sensor architecture, and the Sony Cyber-shot DSC-W350, a slim ultracompact point-and-shoot with a versatile zoom and user-friendly features. Although these cameras target different priorities and periods (launched late 2009 and early 2010 respectively), evaluating them side-by-side brings valuable lessons on sensor technology, image quality, user experience, and suitability for various photographic disciplines.

Why you can trust my evaluation: With over 15 years of hands-on camera testing and thousands of comparisons spanning all photography genres - from studio portraiture to wildlife tracking - I emphasize practical insights and real-world usage. I’ve devoted ample time shooting with both cameras under varied lighting and subject conditions, dissecting their features, ergonomics, focusing performance, and image output. Let’s delve into how these two cameras stand up not just on paper, but through the lens of expert testing.

Getting to Know these Cameras: Design and Ergonomics First

The Sigma DP1s and Sony W350 cater to fundamentally different user approaches. The Sigma is a “large sensor compact,” featuring a fixed 28mm equivalent lens, manual focus capability, and a relatively chunky, understated body designed for control-focused photographers. Conversely, the W350 is a classic ultracompact slider with a versatile 26-105mm zoom intended for casual everyday shooting and lightweight portability.

Size and Handling – Who Fits Your Hand Better?

The DP1s is noticeably larger and heavier when held - even though it’s still a compact camera. Its dimensions of 109 × 60 × 31 mm and weight of 270 grams make it feel substantial, which benefits photographers who appreciate a stable grip and physical controls. The W350 is sleeker and much lighter (91 × 52 × 17 mm; 117 grams), easy to slip into a jacket pocket or small bag.

The grip on the Sigma is more pronounced, with tactile buttons providing easy access to manual exposure controls, shutter priority, and aperture priority modes. The W350, meanwhile, emphasizes simplicity with minimal buttons and no manual exposure modes, targeting point-and-shoot convenience.

Top-View and Control Layout Insights

Examining the top controls, the DP1s presents a clean, functional design with dedicated dials and buttons, though it lacks illuminated controls or a top information panel - still, staying true to Sigma’s philosophy of disciplined manual operation.

The W350’s top panel is simpler, focusing on the power button and shutter release with an adjacent zoom toggle, geared to ease-of-use rather than technical control.

The differences in control layout reflect divergent philosophies: Sigma’s DP1s aims for photographer engagement and tactile feedback; Sony’s W350 prioritizes stealth and straightforward operation.

Sensor Technology and Image Quality: Big Differences in the Heart of the Cameras

This segment is crucial since sensor performance largely dictates output quality, particularly in compact cameras.

The Sigma DP1s Sports a Unique Foveon X3 APS-C Sensor

Unlike conventional sensors, the DP1s uses a Foveon X3 CMOS sensor measuring APS-C size (20.7 × 13.8 mm) with around 5 megapixels effective resolution (2640 × 1760 pixels). The Foveon sensor does something special: It captures color information at three depths (red, green, blue) rather than using a Bayer array demosaicing. This theoretically results in more accurate color rendition and ultra-sharp detail per pixel, especially in controlled lighting.

Despite the relatively low pixel count, I found the DP1s files to be surprisingly rich in color depth and sharpness. Skin tones appear natural and nuanced, albeit not as immediately punchy as Bayer sensors in post-processed JPEGs. The color fidelity is excellent when shooting RAW and processing on Sigma’s proprietary software. However, the lower resolution and relatively slow AF put boundaries on fast action and cropping flexibility.

Sony W350: A Conventional 14-Megapixel CCD Sensor

Sony employs a 1/2.3-inch CCD sensor (6.17 × 4.55 mm), far smaller than the DP1s sensor, but with a higher pixel count - 14 MP (4320 × 3240 pixels). This results in much higher nominal resolution but less dynamic range and higher noise levels at elevated ISOs compared to the DP1s. The CCD technology delivers pleasant color reproduction but falls short in low light and high contrast scenarios.

The W350’s zoom lens (equivalent 26-105 mm, aperture f/2.7-5.7) adds framing versatility that the DP1s lacks.

Real-World Image Quality Comparison

In my tests under various light conditions:

• The DP1s excels at low ISO, producing images with smoother tonal gradation and sharper micro-contrast detail.
• The W350 has the advantage on zoom range but introduces more noise beyond ISO 400, with limited dynamic range.
• Both cameras have anti-aliasing filters, but the DP1s’s unique sensor means less color fringing and moiré in specific scenarios.

Viewing and User Interface: The Window to Your Photos

Both models feature fixed LCD screens - no electronic viewfinders to peek through - and similar resolutions (230k dots), which is modest by today’s standards.

The DP1s comes with a 2.5-inch LCD that is fixed and quite basic. Its interface, while offering manual controls, feels dated, lacking things like touchscreen or live histogram feedback. The Sony W350 improves slightly with a 2.7-inch fixed LCD, also non-touch but a bit more responsive and brighter, aiding framing and review.

Neither camera offers illuminated buttons or an interface optimized for rapid menu navigation, but the DP1s demands more user familiarity with manual exposure modes, whereas the W350 makes casual shooting easier.

Exploring Performance Across Photography Genres

Let’s break down how these cameras perform in different photographic disciplines through practical testing:

Portrait Photography: Handling Skin Tones and Bokeh

• Sigma DP1s: The APS-C Foveon sensor brings out extremely rich skin tones with excellent color depth and smooth tonal transitions, especially when using RAW format processed in Sigma Photo Pro software. The fixed 28mm equivalent lens at f/4 (approximate max aperture) delivers natural perspective but lacks significant background blur since it’s a wide-angle and fixed focal length, limiting bokeh effects.

• Sony W350: Provides a more flexible zoom, with some compression at the tele end (105mm equivalent) helping isolate subjects with background blur. However, its small sensor limits depth-of-field control, producing less creamy bokeh and flatter color depth. JPEGs out of camera look pleasing but less nuanced than the Sigma.

Recommendation: For skin tone fidelity and color nuance, the DP1s shines; for casual portraits with framing flexibility, W350 is preferred.

Landscape Photography: Dynamic Range and Resolution Stand Out

Landscape shooting demands high resolution and wide dynamic range for detailed shadows and highlights.

• The DP1s's APS-C sized Foveon sensor offers richer dynamic range especially in RAW files than the Sony’s compact CCD sensor, though the 5-megapixel resolution limits large print potential or heavy cropping.

• The Sony W350 can produce higher megapixel images but struggles handling highlight retention and shadow detail due to its small sensor.

Notice also that neither camera features weather sealing - a drawback if frequently shooting outdoors in challenging conditions.

Wildlife Photography: Speed and Reach Considerations

• Autofocus on both is single-point contrast detection and relatively slow; neither camera supports continuous AF tracking or fast burst shooting.

• The W350’s 4X zoom (26-105mm equivalent) gives some telephoto reach, but this maxes out at short telephoto, insufficient for distant wildlife.

• The Sigma’s fixed wide lens and manual focus limit utility for wildlife unless close and stationary.

Sports Photography: Tracking and Frame Rates

Neither camera is designed for high-speed shooting. The Sony W350 offers a paltry 1 fps continuous shooting, and the Sigma DP1s has no continuous burst mode. Tracking moving subjects is not viable here.

Street Photography: Discretion and Portability

The Sony W350’s smaller size and lighter weight make it more pocketable and discreet for street use. The quick auto-focus and zoom versatility help for spontaneous moments.

The Sigma DP1s is bulkier and slower but with a wide 28mm field of view perfect for environmental street shots if you prioritize image quality over speed.

Macro and Close-Up Photography

The Sony W350 shines here with a macro focusing range down to 10 cm, allowing you to capture detailed close-ups easily, while the DP1s lacks dedicated macro focusing or close range capability, constrained by its fixed lens and manual focus.

Night and Astro Photography

Low-light performance depends heavily on sensor size, native ISO sensitivity, and noise control.

• The DP1s native max ISO is 800, with noisy images beyond that; however, the larger sensor and color fidelity can produce surprisingly clean images at ISO 400 if exposure is optimized.

• W350’s ISO maxes at 3200 but noise rises rapidly; combined with its small sensor, image quality in very low light or astro scenarios is limited.

Neither camera features specialized astro modes or extended exposure options beyond a 30s max shutter speed for the DP1s and 2s min for Sony.

Video Capabilities: Modest and Basic

The Sony W350 edges ahead here with HD video recording at 1280 × 720 pixels at 30 fps. The files are JPEG format with no advanced codecs or microphone input, suitable for casual video clips.

The DP1s does not have dedicated video recording functionality beyond Motion JPEG still playback, limiting multimedia versatility.

Neither camera offers advanced stabilization during video; Sony W350 includes optical image stabilization for stills but not explicitly for video.

Travel Photography: Versatility, Battery, and Weight

Travel photographers often value a lightweight, versatile camera with good battery life and reliable storage.

• The Sony W350’s ultracompact body, zoom lens, and Memory Stick slot make it a convenient grab-and-go camera. Its battery model NP-BN1 is widely available, but exact battery life is moderate by modern standards.

• The Sigma DP1s is heavier, bulkier, and uses SD/SDHC cards with manual focusing - ideal for travelers wanting uncompromised image quality in a compact package but willing to sacrifice convenience.

Professional Workflows: File Handling and File Quality

• Sigma DP1s stands out with RAW file support and unique high-quality Foveon sensor files. These require proprietary Sigma Photo Pro software for optimal processing, adding complexity to workflow but yielding superior output fidelity.

• The Sony W350 captures JPEG-only files, no RAW support, limiting post-processing flexibility for professionals.

Neither has tethering, robust connectivity, or rugged build quality conventional in modern professional cameras.
