Sigma DP2s vs Sony W350

The Sigma DP2s vs. Sony Cyber-shot DSC-W350: An Unlikely Matchup Between a Large-Sensor Compact and an Ultracompact

In the vast jungle of camera options, it’s not oft that we pit a large-sensor compact like the Sigma DP2s against a tiny ultracompact contender, the Sony Cyber-shot DSC-W350. Yet, here we are, setting the stage for a head-to-head comparison that offers insights beyond specs - an exploration of priorities, compromises, and photographic philosophies. I’ve spent hours with both, testing in varied scenarios and pushing their limits, so let’s unpack what you actually get from these two very different machines.

Size Matters: Ergonomics and Handling Differences

The first thing that hits you - literally if you carry them - is the size and heft of the two cameras. The Sigma DP2s weighs in at a respectable 280 grams with a body dimension of 113mm wide by 60mm tall and 56mm thick, offering a chunkier, more substantial feel. On the other side of the ring, the Sony W350 is featherlight at just 117 grams and flat like a credit card at 91mm by 52mm and a mere 17mm thickness. For a street photographer or someone who prizes portability like a traveler, the Sony wins hands down. Slip it in your pocket, and you barely notice it.

But heft brings its own pros. The DP2s, thanks to its APS-C sized Foveon X3 sensor (20.7 x 13.8mm), benefits from a grip and body design that encourages deliberate shooting - a rarity in compact cameras of its era. Its larger size also allows more comfortable button placement and a steadier hold, particularly useful when slow shutter speeds come into play. The Sony’s ultracompact form factor, while charmingly pocket-friendly, compromises on tactile feedback and can feel fiddly when trying to operate manually or in challenging lighting.

The top panel design echoes these philosophies. The DP2s keeps things minimalist but functional, with dedicated buttons for shutter priority and aperture priority modes - a boon for enthusiasts who like some manual control. The Sony opts for a more simplified approach, eschewing manual modes altogether. For those who appreciate physical controls with a tactile feel, the DP2s’ slightly analog charm wins out.

Sensor Technology: A Lesson in Pixels and Color Science

Here’s where the real chasm opens up. The Sigma DP2s features a proprietary Foveon X3 CMOS sensor with an APS-C sized sensor area of approximately 285.7mm² and an effective resolution of 5 megapixels. Now, before you gasp at the low resolution number, understand that the Foveon sensor captures full color at every pixel location using three stacked sensor layers, rather than the Bayer filter used by most sensors (including the Sony’s CCD).

The Sony W350, conversely, sports a 1/2.3-inch CCD sensor which measures just 6.17 by 4.55 millimeters, roughly 28.1mm² - around one-tenth the surface area of the Sigma’s sensor but with a much higher resolution of 14 megapixels.

What does this mean practically?

• The Sigma’s Foveon sensor famously delivers exquisite color depth, natural tonal graduations, and very fine detail rendition at low ISO, despite a nominally low resolution. The “5 megapixels” number undersells it - in real life, the color and detail fidelity are comparable to much higher-res Bayer sensors.
• The Sony’s small 1/2.3” sensor can cram pixels in tight - but at the cost of noise performance, dynamic range, and color accuracy. It’s perfectly fine in bright conditions, but once you crank the ISO or shoot shadows, the noise creeps in fast.

In hands-on testing using controlled scenes with fine detail and subtle color transitions (think textured fabric, foliage, and skin tones), the Sigma DP2s produced nuanced images with smoother tonal blending. On the flip side, the Sony delivered sharper detail at base ISO thanks to more pixels, but with harsher color transitions and early onset of noise after ISO 200.

LCD and User Interface: Seeing is Believing

Screen size and resolution are neck-and-neck but nuanced in use. Sigma offers a 2.5-inch fixed-type LCD with 230k dots, while Sony has a slightly larger 2.7-inch screen, also at 230k dots resolution.

The Sony's screen, being marginally larger, offers a slightly more comfortable viewing experience. However, neither boasts a touchscreen or articulating feature, so framing can sometimes be a guessing game - especially outdoors under harsh light.

Moreover, both cameras lack electronic viewfinders, pushing reliance onto the rear LCD. For manual focusing or critical composition, this can be limiting. The DP2s, with its greater physical size, is a bit more manageable in manual focus via live view, though the low resolution LCD doesn't help nail focus perfectly without zooming in.

Autofocus and Lens: Focus Speed and Image Character

With focus, the differences become stark. The DP2s uses contrast-detection autofocus (AF) with no phase-detection and no continuous AF or face detection. It features a fixed 41mm equivalent prime lens (thanks to a 28mm actual focal length with 1.7x crop factor), which is sharp, bright, and optimized for image quality at wide apertures.

The Sony W350 packs a 4x zoom lens from 26-105mm equivalent with an f/2.7-5.7 aperture range - versatile for casual shooting, macro (down to 10cm), and moderate telephoto needs. Autofocus uses contrast detection as well, but with 9 AF points and more automation, including center-weighted metering and spot metering options.

In real-world shooting, the Sony’s autofocus is slower, especially in low light, struggling to lock focus on flat or low-contrast subjects. The DP2s, despite lacking fancy AF systems, can be surprisingly effective for static subjects when focusing manually or using magnified live view. But in fast-moving situations, both cameras fall short compared to modern AF standards.

How They Perform Across Photography Genres

You’re probably wondering: “Okay, I get the specs, but what about portraits, landscapes, wildlife…?”

Let’s break it down.

Portrait Photography: Skin Tones and Bokeh

Portrait work favors good color rendering, accurate skin tones, and pleasing background blur. The Sigma DP2s excels here. Its Foveon sensor renders skin with remarkable delicacy and richness, avoiding the oversaturation or smudging often seen in small-sensor compacts.

The fixed lens, at 41mm equivalent focal length and a bright aperture (around f/2.8), delivers nice background separation, producing smooth, creamy bokeh. This makes the DP2s better suited for portraits despite its relatively modest resolution.

The Sony W350, while versatile focal-length-wise, has a slower maximum aperture (f/2.7 wide, but up to f/5.7 telephoto), limiting background blur. Skin tones can appear somewhat plasticky or posterized in challenging light, and the smaller CCD sensor exacerbates noise and lower dynamic range in portraits indoors or in shade.

Landscape Photography: Resolution and Dynamic Range

Landscape shooters need sharpness, dynamic range, and ideally weather sealing. The Sigma's APS-C Foveon sensor gives an edge in rendering subtle textures - leaves, rocks, sky gradients - with smooth tonal gradations. Its 3:2 and 16:9 aspect ratios cater to creative framing, though the modest 5MP output limits large prints.

The Sony W350, offering 14MP at 4:3 or 16:9 aspect ratios, can produce images you can crop more aggressively, but dynamic range and shadow recovery are limited by the small sensor.

Neither camera is weather sealed, so caution is advised outdoors in adverse conditions.

Wildlife and Sports Photography: Autofocus and Speed

Here, the Sony W350 is at a disadvantage due to a slow contrast AF system and a continuous shooting rate of only 1 fps.

The Sigma DP2s has a slightly faster burst mode at 3 fps, but no continuous AF or tracking, making both cameras poor choices for action or wildlife photography where quick and accurate focus tracking is essential.

You’d be better served by dedicated DSLRs or mirrorless cameras with phase-detection AF for these genres.

Street Photography: Discretion and Portability

For street photography, the Sony W350 shines thanks to its ultracompact size and light weight, enabling easy, unobtrusive shooting.

The fixed prime lens on the DP2s offers a tighter field of view (41mm, close but not quite the classic 35mm), and though larger, it still remains fairly pocketable.

Quick AF on the Sony is a bit sluggish, which can frustrate candid shooting, while the DP2s requires manual focus patience.

Macro Photography: Focus Precision and Detail

Both cameras offer macro capabilities, but the Sony W350 can focus as close as 10cm, which is convenient for casual flower or insect shots.

The DP2s lacks specific macro-mode support and has no focus bracketing or stacking, but its sharp prime lens and high image quality offer better detail capture for macro subjects when focus is nailed.

Neither offers image stabilization, so good technique or a tripod is essential.

Night and Astro Photography: High ISO and Exposure Control

The Sigma DP2s maxes out at ISO 3200 but performs best at base ISO 50 to 200. The unique Foveon sensor retains color accuracy at low ISOs but struggles at high ISOs, showing noise and reduced dynamic range.

The Sony W350 also reaches ISO 3200 but uses a CCD sensor, which tends to add chroma noise earlier. Neither camera supports longer shutter speeds beyond 15 seconds on the Sigma and 2 seconds on Sony, making long exposure night or astro photography challenging.

The DP2s supports manual exposure and shutter/aperture priority modes, giving finer creative control in low light; the Sony lacks manual exposure options, limiting versatility.

Video Capabilities: Recording Resolutions and Stabilization

Video is a weak point for both.

The Sigma DP2s records video at a very low resolution - 320 x 240 pixels in Motion JPEG, hardly suitable beyond novelty clips.

The Sony W350 offers 720p HD video at 30fps, again in Motion JPEG, with optical image stabilization helping smooth handheld footage.

Neither has microphone inputs, so audio quality is basic.

Build Quality, Weather Resistance, and General Reliability

Neither camera features weather sealing, dust proofing, or shockproofing, which is typical of cameras in their respective classes and price brackets.

The Sigma has a sturdy aluminum alloy build compared to the W350’s primarily plastic body, which feels less robust over time.

Ergonomics and Interface: Buttons, Menus, and Controls

The Sigma DP2s offers manual focus with focus ring and exposure compensation with straightforward button placement catered to serious shooters. The menu system is minimalistic but not the most intuitive, requiring adjustment for first-timers.

The Sony, by contrast, favors simplicity - automatic shooting modes dominate, with basic adjustments tucked away in less accessible menus. Buttons are small to match the compact form factor, but this compromises ease of use for anyone with larger hands.

Neither has touchscreens or articulating displays, reflecting their 2010 era design.

Lens Ecosystem and Compatibility

The cameras both feature fixed lenses:

• Sigma DP2s: A 41mm equivalent prime lens with exceptional optical quality, no zoom, focused on image quality over versatility.

• Sony W350: A 4x zoom covering 26-105mm equivalent, offering flexibility for everyday photography but at the expense of optical performance in low light.

This distinction is key: the DP2s is a “quality-first” camera, ideal for photographers concentrating on image quality and willing to adapt their shooting style to the fixed focal length. Sony’s W350 is an “all-rounder” for casual point-and-shooters.

Battery Life and Storage

Both cameras accept single storage cards - SD/SDHC/MMC for Sigma, Sony using Memory Stick Duo/Pro Duo formats plus internal memory.

Exact battery life figures aren’t officially published, but real-world use indicates:

• Sigma DP2s: Modest battery life, typical of large sensor compacts with active live view, manual focus, and no advanced power-saving.

• Sony W350: Longer battery life due to smaller sensor and simpler electronics; this supports casual users better.

Connectivity and Wireless Features

Neither camera offers Wi-Fi, Bluetooth, NFC, or GPS. The Sony includes an HDMI output port, allowing playback on TVs, while the Sigma has USB 2.0 for data transfer but no video-out options.

In a 2024 context, these omissions make modern sharing cumbersome.

Price-to-Performance Analysis

Launching at about $940, the Sigma DP2s was a boutique compact, aimed at photographers craving image quality and color fidelity in a pocketable form (for 2010). Its price reflects its niche sensor technology, unique rendering, and build quality.

The Sony W350, with a street price near $200, is an affordable ultracompact option for casual shooters wanting ease as priority over technical prowess.
