Ricoh WG-50 vs Sigma DP1: A Deep Dive for Photography Enthusiasts

As someone who’s spent a fair chunk of my life testing cameras in all sorts of wild conditions (from scorching deserts to rain-soaked forests), I always find it fascinating to compare two very different compact cameras that promise to serve niche needs. Today, I’m pitting the rugged Ricoh WG-50 against the venerable Sigma DP1. Despite both being compacts, these two come from opposite ends of the photography spectrum - one is built like a tank for adventure, the other is a high-concept large-sensor shooter aimed at image quality geeks.

If you’re a photography enthusiast or professional trying to pick a camera that fits either a very practical use case or a somewhat purist image quality obsession, you’re in the right place. I'll break down everything - from sensor tech and usability to real-world performance across multiple genres - so you can make an informed, confident decision.

What They Are: Rugged Utility vs Large Sensor Artistry

Meet the Ricoh WG-50

The WG-50 is a rugged, waterproof compact camera designed for adventure seekers who want a no-fuss, durable shooter. Announced in mid-2017, Ricoh packed it full of environmental sealing: waterproof, shockproof, and freezeproof. It has a fixed 28-140mm equivalent zoom lens, 16MP 1/2.3-inch BSI-CMOS sensor, with an 8 fps burst mode and essentials like digital image stabilization.

This is the camera you take snorkeling, hiking, or anywhere your regular gear fears to tread.

Say Hello to the Sigma DP1

The Sigma DP1 is a large sensor compact launched in 2008, featuring a fixed 28mm equivalent prime lens paired with the unique Foveon X3 APS-C sensor. Its total sensor area is almost 10 times larger than the Ricoh’s, promising far greater detail and tonal depth - if you’re willing to accept its slower, deliberate shooting style and older tech quirks.

It’s a camera for the contemplative artist, the street shooter wanting sharp prime optics, or anyone obsessed with top-tier image quality in a compact form.

Physical Handling & Ergonomics: Clubs for Thumbs or Adventure-Ready?

Before I get into image quality and tech, let’s talk size and handling.

Right off the bat you can see the WG-50 boasts a smaller, thinner profile (123x62x30mm) and is notably lighter - a mere 193 grams compared to the DP1’s chunkier 270 grams and boxier dimensions (113x60x50mm). The Ricoh’s more ergonomic sculpted body with textured grips is tailored for wet, gloved hands.

Meanwhile, the DP1 feels more like a pocketable rangefinder-style compact, but its rectangular boxy shape and larger depth might feel bulky for some pockets. You won’t find any fancy thumb clubs here - it’s minimalist by design, which some photographers love for distraction-free shooting, but could be tricky for long handheld sessions.

Top-View Controls & User Interface: Simplicity vs Precision

Looking down at their top decks reveals their very different philosophies. The WG-50 offers a handful of tactile buttons and a zoom rocker, plus modes like underwater & macro very quickly accessible - perfect for rugged fast action. The controls are straightforward and rubberized for grip.

In contrast, the DP1 has a more stripped-back dial on top for shutter speed control and an aperture ring on the lens itself. This suits photographers who prefer manual control and deliberate exposure adjustments but means a steeper learning curve and slower operation in day-to-day shooting.

Sensor Size & Image Quality: The Big Divide

When it comes to image quality, sensor size is king. Here’s a direct comparison:

• Ricoh WG-50: 1/2.3-inch BSI-CMOS, 16MP, 28.07 mm² sensor area - small but modern.
• Sigma DP1: APS-C sized Foveon X3 sensor, approx 20.7x13.8mm, about 285.66 mm² - huge by comparison.

The RG-50’s smaller sensor naturally limits dynamic range, low light performance, and ultimate detail. The WG-50 shoots JPEG only and lacks RAW support, so fine editing latitude is limited.

The DP1’s Foveon sensor uniquely captures full color depth at every pixel layer - offering outstanding color fidelity, skin tone rendition, and a three-dimensional look that few other sensors can match. It outputs lossless RAW, benefiting pros and advanced amateurs wanting full creative flexibility.

My testing showed:

• The WG-50 produces sharp files in bright light, decent color saturation, but noisy shadows and banding appear beyond ISO 800.
• The DP1 yields rich, painterly files with nuanced gradations and higher detail retention, especially at base ISO 100-200. But it demands slower shutter speeds and tripod support outside bright conditions to avoid soft images from motion blur or noise from ISO boosts (max 800).

Back Screen & Live View: What You See is What You Get

You get a fixed 2.7-inch 230k-dot display on the WG-50 and a slightly smaller 2.5-inch same-resolution screen on the DP1. Neither offers touch support or articulating screens - no surprise given their rugged and large-sensor retro natures.

The Ricoh’s screen is luminous enough for daylight framing and previewing underwater shots (just keep an eye for reflections). The Sigma’s screen is quite dim and less sharp by today’s standards, making manual focusing even more challenging.

Autofocus & Shooting Speeds: Where Practicality Meets Patience

Ricoh WG-50:

• Contrast-detection with 9 focus points and face detection.
• Continuous AF available for tracking moving subjects.
• Burst shooting up to 8 fps - not bad for a rugged compact.

Sigma DP1:

• Single contrast-detection AF only; no continuous focus or tracking.
• No burst mode.
• Manual focus is often preferred due to the AF’s sluggishness.

For someone shooting wildlife or sports, the Ricoh is clearly the better fit, capable of keeping up with fast movement. The DP1 demands a slow, thoughtful approach - ideal for static subjects or urban landscapes.

Build Quality & Weather Resistance: Ready for Rough and Tough?

• The WG-50 scores big here: waterproof down to 14m, freezeproof to -10°C, shockproof from 1.6 meters, dustproof, and almost all-weather proofing you could ask for. Ideal for hiking, skiing, snorkeling, or construction sites.

• The DP1 is a sensitive soul. No weather sealing, no rugged features. It’s a camera for controlled environments - studios, urban strolls, or casual outdoor shoots in fair weather.

Lens Quality & Flexibility: Zoom vs Prime

• WG-50: 5x zoom from 28-140mm equivalent, F3.5-5.5 aperture. Versatile for landscapes to medium telephoto.

• DP1: Fixed 28mm prime, F4 aperture. Lens is razor sharp with excellent corner to corner clarity, but no zoom. You work by moving your feet.

If you want a compact with ready-to-roll zoom flexibility - WG-50 wins hands down. For those obsessed with optical quality, the DP1’s prime lens is still exceptional, albeit limiting for some.

Battery Life & Storage: Powering Your Shoots

• WG-50 uses a D-LI92 rechargeable battery, rated for about 300 shots per charge - decent for a compact. It uses standard SD/SDHC/SDXC cards.

• DP1 uses proprietary battery (no exact rating given) and stores images on SD/MMC cards. Battery life tends to be shorter due to power-hungry electronics.

If you’re a traveler who hates running out of juice, the WG-50’s better battery life and charging options will be appreciated.

Connectivity & Extras: Modern Conveniences vs Vintage Simplicity

The Ricoh offers wireless connectivity for quick image transfers and an HDMI port for external displays - nice if you like sharing quickly without a computer.

The Sigma DP1 is old-school: USB 1.0 connectivity only, no wireless, no HDMI. It’s a camera you mostly download images from manually.

Real-World Performance Insights Across Photography Types

Let me walk you through how these cameras fare when pushed in different photographic genres, based on rigorous field testing.
