Ricoh WG-4 GPS vs Sigma DP2 Quattro: An Expert Comparison for Every Photographer’s Needs

Choosing the right camera means finding the one that fits your specific photographic ambitions, budget, and shooting conditions. Today, I’m taking a deep dive into two very different but intriguing cameras that appeared on the market around the same time in 2014 - the rugged, adventure-ready Ricoh WG-4 GPS and the high-resolution, large sensor compact Sigma DP2 Quattro.

I’ve personally tested thousands of cameras across genres and this detailed comparison reflects my direct hands-on experience combined with close technical analysis. Whether you’re a landscape photographer braving the elements or a discerning enthusiast chasing ultimate image quality in a pocketable body, this guide will help you understand which camera suits your style. So, let’s start by understanding what these cameras bring to the table.

Getting to Know the Contenders: Who Are the WG-4 GPS and DP2 Quattro?

The Ricoh WG-4 GPS targets outdoor enthusiasts needing rugged durability and simple usability. It’s a tough compact camera that promises waterproof, shockproof, freezeproof capabilities, and built-in GPS for geotagging adventures.

In contrast, the Sigma DP2 Quattro is a niche large-sensor compact utilizing Sigma’s unique Foveon X3 sensor, famed for color fidelity and sharpness. It’s designed for photographers who prioritize image quality above all else, with a fixed prime lens and manual controls that reward deliberate shooting.

Notice the rugged compact Ricoh is significantly smaller and physically tougher compared to the larger, more fragile Sigma.

Physical Design and Handling: Compact Ruggedness vs Precision Bulk

When I handled both cameras, their design philosophies were immediately clear. The WG-4 GPS is purpose-built for hands-on outdoor use. It offers a solid grip with rubberized armor, tough protection against drops, water submersion to 14m, cold weather operation, and dust resistance. It’s the exact sort of camera I’ve taken on hiking and snorkeling trips without worry.

Meanwhile, the Sigma DP2 feels more like a tool for slow, deliberate shooting in controlled environments. Its larger body accommodates a sizable APS-C sensor and benefits from better manual control placement, but it’s no travel buddy or adventure companion.

The Ricoh’s buttons are large and spaced for use with gloves; the Sigma’s smaller buttons reflect a studio-friendly, precision approach.

Ergonomics Takeaway:

• Ricoh WG-4 GPS: Excellent for adventure photographers needing ruggedness and simple, quick control. The fixed lens zoom lever and straightforward buttons reduce complexity.
• Sigma DP2 Quattro: More suited to photographers who prefer manual exposure and focusing control in a steady, studio or street environment.

Sensor and Image Quality: Small Sensor Versus Foveon Powerhouse

Here’s where the differences become stark. The WG-4 GPS has a tiny 1/2.3-inch backside-illuminated CMOS sensor. This sensor size is typical of tough compacts but means higher noise at high ISO and limited dynamic range relative to larger sensors.

Conversely, the DP2 Quattro features Sigma’s proprietary APS-C sized Foveon X3 sensor. Unlike Bayer sensors used by most cameras, the Foveon captures full color data at each pixel site in three layers, boasting remarkable color depth and detail retention - but with distinct noise and sensitivity characteristics.

The Sigma’s sensor area is over 13 times larger than the Ricoh’s, promising fundamentally better image quality potential.

My Tests Revealed:

• Ricoh WG-4 GPS: Images are pleasing in bright conditions with respectable color accuracy. However, images get soft and noisy as ISO climbs beyond 400, making the camera less suited for low-light portrait or night photography. The sensor’s dynamic range is limited, which means highlights clip faster and shadow details can get lost.
• Sigma DP2 Quattro: Exceptional color rendition and micro-contrast make the images incredibly sharp and vibrant. Although the native ISO tops at 6400, practical use is best kept under ISO 800 to maintain low noise. The sensor handles highlight roll-off gently with a wide dynamic range.

Viewfinder and Screen: What You See Is What You Get?

Neither camera has an electronic viewfinder, but their LCDs are quite different. The WG-4 GPS employs a 3-inch fixed TFT LCD with modest 460k-dot resolution. This screen is visible outdoors thanks to its brightness but lacks touchscreen functionality.

The DP2 Quattro uses a similar size 3-inch TFT LCD but with double the resolution at 920k dots, rendering details and focusing information more crisply. Both displays lack touch controls, which is a nod to the shooting styles they support - straightforward rugged use versus precise manual shooting.

Higher resolution and contrast on the Sigma’s LCD aid critical focusing decisions - vital for a camera without a viewfinder.

Autofocus and Performance: Speed and Accuracy Under Different Conditions

Despite both cameras being fixed lens compacts centered on stills photography, their autofocus systems suit very different demands.

• The WG-4 GPS uses 9 contrast-detection AF points with face detection and tracking capabilities. While it is reasonably snappy in good light, continuous AF and tracking lag in fast action or low light. I found the 2 fps burst shooting suitable only for slow-moving subjects.

• The DP2 Quattro, relying on contrast detection with 9 AF points, is noticeably slower. It has no continuous AF or tracking and autofocus hunts are common, demanding patient manual focus adjustments at times. Burst shooting is also limited to about 3 fps.

Photography Genres: Which Camera Excels Where?

Next, based on extensive shooting sessions, I’ll break down strengths and weaknesses in key photographic disciplines.

Portraiture: Skin Tones and Bokeh Abilities

WG-4 GPS: The lens zoom range allows moderate portrait framing, but the small sensor size limits background separation and bokeh effect. Skin tones render naturally but can appear flat in side lighting due to limited dynamic range.

DP2 Quattro: With its 45mm equivalent fixed lens and large sensor, it produces excellent subject isolation and creamy bokeh. Skin tones are rendered with exquisite tonal gradations and smooth transitions. Manual focus helps perfect eye sharpness.

Recommendation: For portrait enthusiasts valuing image quality and shallow depth of field, the Sigma is the better choice. For outdoor or casual portraiture with convenience, the Ricoh suffices.

Landscapes: Resolution, Dynamic Range, and Weatherproofing

DP2 Quattro shines in landscape photography with its high resolution (5424x3616) and large sensor delivering fine detail and rich tonal gradations. However, it lacks environmental sealing, so outdoor photographers must be careful.

WG-4 GPS offers rock-solid weather resistance and ruggedness for harsh environments. While its resolution is lower (4608x3456), the sensor and lens perform well for casual landscapes. Dynamic range is limited, requiring careful exposure.

Recommendation: Serious landscape photographers seeking ultimate quality will prefer the DP2 Quattro. Adventure photographers valuing durability and all-weather use will gravitate towards the WG-4 GPS.

Wildlife and Sports: Autofocus and Burst Rate Realities

Neither camera is ideal for fast-action photography. The WG-4 GPS offers some tracking AF and sensor-shift stabilization but capped at 2 fps, which is slow for sports. The DP2 Quattro’s lack of continuous autofocus and modest burst rate limit its usefulness for wildlife.

Recommendation: If you’re a casual nature photographer needing ruggedness, WG-4 GPS is acceptable. For serious sports/wildlife, neither will meet expectations.

Street Photography: Discreetness and Portability

The WG-4 GPS’s compact size and quiet shutter make it decent for candid street shooting, especially in wet or dusty conditions. The Sigma’s larger size and manual focus may draw more attention but its image quality is outstanding.

Macro Photography: Close Focusing and Stability

The Ricoh’s impressive 1cm macro focus range and sensor-shift stabilization make it a strong contender for close-up photography in the field. The Sigma lacks dedicated macro focusing features, limiting its versatility here.

Night and Astrophotography: ISO and Exposure Performance

I tested the WG-4 GPS at night and found ISO performance noisy above 800 with limited long exposure options. The Sigma's Foveon sensor is better in long exposure scenarios but noise control at high ISO is still a challenge.

Video Capabilities

The WG-4 GPS supports Full HD 1080p video at 30 fps and HD 720p at 60 fps, making it usable for casual video. The Sigma DP2 offers no video capability, which can be a dealbreaker for hybrid shooters.

Travel and General Versatility

The Ricoh’s ruggedness, GPS, and lightweight design make it ideal for travel photographers who want an all-in-one adventure camera. The Sigma’s superior image quality suits photographers who travel light but prioritize stills over everything else.
