Sigma DP2s vs. Sony WX220: An Expert Comparison for Photography Enthusiasts

Choosing the right camera can be tricky, especially when two models come from vastly different design philosophies. Today, I’m putting under the microscope the Sigma DP2s, a large-sensor fixed-lens compact released in 2010, against the Sony Cyber-shot DSC-WX220, a 2014 ultracompact with a hefty zoom range and a more consumer-oriented feature set. Both have their quirks, strengths, and limitations. After testing these cameras extensively across my usual battery of scenarios - from portraits to wildlife to travel photography - I can tell you which one deserves your hard-earned cash.

Let’s dig in.

First Impressions: Size, Ergonomics, and Handling

If a camera feels good in your hands, you’re halfway to loving it. The Sigma DP2s is a chunkier, heavy little beast weighing 280 grams, with dimensions of 113 x 60 x 56 mm. The Sony WX220 is much smaller, lighter (just 121 grams), and slender at 92 x 52 x 22 mm.

The DP2s’s heft comes from its large APS-C Foveon sensor - more on that later - and bulky manual controls. It feels solid and well-built with a premium heft, but the camera’s fixed-lens and dated interface make it less comfortable for quick snaps, especially for street or travel photography.

The WX220, meanwhile, slips into any pocket with ease. Its slimline ultracompact body suits photographers who want something discreet, handy, and lighter for daily carry. However, it’s not designed for serious manual manipulation - you won’t find any dedicated control dials, which limits quick creative control.

Top Layout and Controls: Minimal vs. Manual Focus

Taking a look from the top:

The Sigma sports a handful of physical buttons and dials targeted at manual exposure enthusiasts, including shutter speed and aperture priority modes and a few quick access buttons. But with no dedicated autofocus point selection and a fixed lens, you’ll be relying mostly on center-weighted metering and contrast-detection autofocus - which is painfully slow by today’s standards.

Sony’s WX220 keeps controls to a bare minimum, focusing on simplicity and auto modes geared towards point-and-shoot comfort. It lacks manual exposure options and relies entirely on its intelligent processor and autofocus to do the heavy lifting.

Ergonomics verdict: If you crave control and don’t mind handling quirks, the DP2s offers tactile satisfaction. If you want a no-fuss grab-and-go pocket camera, the WX220 wins hands down.

Sensor Technology and Image Quality Face-Off

This is where the rubber hits the road, and how these cameras diverge most dramatically.

• Sigma DP2s Sensor: APS-C sized CMOS (Foveon X3)

  • Sensor area: 285.66 mm²
  • Resolution: 5 MP (effective)
  • No anti-alias filter

• Sony WX220 Sensor: 1/2.3 inch BSI-CMOS

  • Sensor area: 28.07 mm²
  • Resolution: 18 MP
  • Anti-alias filter included

What the Numbers Mean for You

The Sigma DP2s features the rare and controversial Foveon X3 sensor, which captures full color information in three layers. This unique design tends to deliver strikingly sharp images with rich color depth and fine detail, especially at lower ISOs, albeit with a lower pixel count (the “5 MP” is misleading - it produces detail comparable to a roughly 14 MP Bayer sensor in terms of perceived resolution). However, the native ISO maxes out at 3200, and noise performance in low light is mediocre at best.

The Sony WX220 employs a common, conventional 1/2.3” BSI sensor with a high pixel count (18 MP), which translates to images with more megapixels but undersized pixels. This sensor excels in daylight and bright conditions with good detail, and a native ISO range up to 12800 lets you shoot in darker scenes while maintaining acceptable noise levels, thanks in part to Sony’s Bionz X processor.

Real-world Image Quality Observations

• Portraits: The Sigma’s APS-C sensor and fixed 41mm equivalent lens deliver creamy bokeh and excellent tonal gradation, showing off natural skin tones. The WX220’s small sensor and narrow aperture range produce flatter portraits with more background clutter.

• Landscape: The Sigma’s sensor boasts superior dynamic range and color depth. Landscapes appear vibrant with rich shadows and highlights. The WX220’s smaller sensor restricts the dynamic range somewhat, though its higher resolution partly compensates for cropping.

• Low light & ISO: Here, the Sony WX220 handily outpaces the Sigma. The WX220’s image stabilization and higher ISO ceiling lend it better low-light usability. The Sigma struggles beyond ISO 800, producing noisy images.

• Detail & noise: At base ISOs, the DP2s’s Foveon sensor captures textures and subtle detail beautifully. The WX220 sharpness is acceptable for its class but relies on digital sharpening and noise processing that can look plasticky.

Bottom line: For image quality purists who prioritize rich tonal gradation and color fidelity, the Sigma DP2s is still a delight, despite its low resolution. For versatile shooting including low-light and zoom flexibility, the Sony WX220 outperforms in practical everyday scenarios.

LCD Screens and User Interface

A camera’s rear screen is your constant window to the world, so it needs a good quality display with responsive feedback.

The Sigma DP2s features a modest 2.5” fixed LCD with 230k-dot resolution - by today’s standards, pretty basic and dim. This low-res, non-touchscreen panel offers minimal help in manual focusing or reviewing images on the fly.

The Sony WX220 sports a larger 3” fixed screen with 460k-dot resolution. Though it’s non-touch, the screen is bright, sharp, and pleasant for framing and playback, especially in bright daylight. The interface is streamlined for point and shoot functionality, with easy access to scene modes, zoom, and playback.

If touchscreen or articulating displays are your jam, neither camera fits the bill, but the WX220 is noticeably clearer and more user-friendly.

Autofocus and Shooting Performance

Here we enter territory where the two cameras could not be more different in philosophy.

The Sigma DP2s offers only single autofocus mode with no tracking or face detection, which can cause frustration when trying to nail sharp focus on spontaneous subjects. Its contrast-detection AF system hunts noticeably in low light and with moving subjects.

Sony’s WX220 shines with fast, accurate AF including face detection and tracking, enabling better results for casual portraits, street scenes, and even fast-moving scenarios despite the small sensor. It also offers a faster 10 fps burst rate for capturing fleeting action.

Bottom line: For wildlife, sports, or street photographers needing snappy autofocus and fast shooting, the WX220’s autofocus system is leagues ahead despite its compact sensor.

Lens, Focal Range, and Macro Capabilities

The Sigma DP2s is equipped with a single fixed 41mm equivalent f/2.8 lens, a classic focal length suited to portraits and general-purpose shooting but limited for zoom or wide-angle lovers.

The Sony WX220 sports a versatile 25-250mm equivalent zoom range with an aperture range of f/3.3-5.9, covering wide angle to telephoto. It also has optical image stabilization, very helpful at telephoto lengths.

• Macro focusing: Neither camera is a dedicated macro shooter. The Sony WX220 allows closer focus distances than the Sigma, making it slightly more usable for casual macro or close-up shots.

Video Capabilities: Let’s Get Moving

• Sigma DP2s: 320x240 Motion JPEG video – basically a novelty feature in 2010 terms; don’t expect usable modern video.

• Sony WX220: Full HD 1920x1080 video recording at 60p, AVCHD and MPEG-4 formats supported. Offers moderate video quality with optical stabilization and decent frame rates for casual use.

This is a no-contest situation. The WX220 is vastly superior for videographers and casual video shooting.

Battery Life and Connectivity: Staying Powered and Connected

• Battery Life: The Sony WX220 has a rated 210 shots per charge - typical for ultracompacts but somewhat limiting for full-day shoots. The Sigma’s battery life figures aren’t official, but its manual focus and lack of power-hungry autofocus help it last reasonably well if you pace your shooting.

• Connectivity: The Sony WX220 includes built-in wireless and NFC for easy photo sharing. The Sigma DP2s lacks wireless entirely and relies on USB 2.0 for image transfer - a painful bottleneck today.

Build Quality and Weather Resistance

Neither camera boasts weather sealing or rugged protection. The Sigma feels a bit more robust thanks to its bulk and metal components, but neither is suitable for heavy outdoor abuse.

Practical Real-World Usage by Photography Genre

To make this review truly useful, I tested both cameras side by side across popular photography types to see how they stack up where it counts:

Portrait Photography

The Sigma’s large sensor and fixed 41mm lens produce attractive portraits with excellent skin tone rendition and smooth bokeh. Eye detection is absent, so focus can be tricky for beginners. The WX220’s autofocus with face detection delivers sharp selfies and portraits quickly, but image quality is flatter and less characterful - small sensor blues.

Winner: Sigma DP2s for richness and bokeh, WX220 for ease of use.

Landscape Photography

The Sigma’s dynamic range and color depth make landscapes pop, revealing fine details in shadows and highlights. The WX220’s high-resolution sensor and wide-angle coverage provide versatility but with limited tonal range and noisier shadow areas.

Winner: Sigma for image quality, WX220 for flexibility.

Wildlife and Sports Photography

Autofocus speed and burst rates matter here. The DP2s’s slow contrast detection AF and 3 fps shooting shoot it in the foot. The WX220’s continuous AF, face tracking, and faster 10 fps burst rate help capture action shots, though sensor size limits ultimate image quality.

Winner: Sony WX220 hands down.

Street Photography

The WX220’s tiny size and zoom versatility support candid shots from afar. The Sigma’s bulk and slow AF make it less suited for quick snaps, despite great image quality. The Sigma’s lack of silent shutter limits stealth.

Winner: WX220 for discretion.

Macro Photography

Neither have extraordinary macro capabilities. The WX220’s closer minimum focus distance and optical stabilization give it a slight edge.

Winner: Sony WX220.

Night and Astro Photography

High ISO capability at clean noise levels is critical here. The Sigma’s ISO maxes at 3200 but produces noisy images at high ISO. The WX220 offers ISO up to 12800 but with a tiny sensor, so it struggles with noise as well. Neither is ideal, but the WX220 is better for handheld night shots thanks to stabilization.

Winner: Slight edge to WX220.

Video Recording

This category requires no debate. The WX220 records Full HD video with image stabilization, making it suitable for casual video creatives.

Winner: Sony WX220.

Travel Photography

On the road, size, weight, versatility, and battery life are paramount. The WX220’s compact size, zoom lens, and connectivity make it perfect. The Sigma, while delivering higher image quality, is more cumbersome and lacks sharing options.

Winner: WX220 for most travelers; Sigma for those prioritizing image quality above all.

Professional Work

For professional workflows, RAW support matters. The Sigma offers RAW files, albeit at a low megapixel count, but with detailed color data. The WX220 lacks RAW support - image quality and flexibility are limited for post-production.

Winner: Sigma for RAW and color fidelity, but limited versatility.
