Nikon Coolpix S31 vs Ricoh WG-6: A Thorough Dive into Two Rugged Compacts

Choosing a waterproof compact camera often means balancing ruggedness, image quality, and usability within a specific budget. Today, I’m comparing two models aimed at the adventurous but different segments of the market: the Nikon Coolpix S31, launched in 2013 as an entry-level waterproof compact, and the Ricoh WG-6 from 2018, a more robust and technically advanced option. Both promise to survive tough conditions but diverge heavily in imaging capabilities, user controls, and overall performance.

I’ve put these cameras side-by-side after extensive hands-on testing to help you understand which might be your best fit - whether for family beach holidays, rugged outdoor challenges, or casual underwater shots. Let’s unpack their strengths, compromises, and real-world handling to see how they stand up to modern photography demands.

First Impressions: Size, Build, and Handling in the Wild

When assessing body ergonomics and handling, the feel of the camera in the hand and ease of operation under adverse conditions cannot be overstated. Both cameras flaunt a tough exterior to appeal to those who want splash-proof reliability without needing extra housing.

The Nikon S31 is a small, chunky compact measuring 105x65x42 mm and weighing just 185g, making it very pocketable. Its built-in ruggedness covers waterproofing up to 10m, dust, shock, and freezeproofing - great for family adventures or poolside action without worries. The body form handles well for small hands and kids, with generously spaced buttons but a limited control set, which suits casual users not wanting to fiddle with settings.

By contrast, the Ricoh WG-6 is larger at 118x66x33 mm and heavier at 246g, reflecting its more robust construction. It pushes waterproofing deeper (to 14m), adds crushproofing, and ups freezeproofing standards, clearly targeting serious outdoor enthusiasts and professionals. The camera’s shape is boxy but with pronounced grips and textured surfaces that provide secure handling even while wearing gloves or underwater gloves.

From an experience standpoint, the WG-6 feels like a camera you can rely on in demanding environments - from mountain hikes to scuba dives - while the S31 is a better companion for casual users needing splash resistance and easy operation. The Nikon’s smaller size is great for portability, but the WG-6’s build quality and enhanced ruggedness win on durability.

Control Layout and User Interface: Simple vs. Capable

How much control do you really want out of a rugged compact? For many, it’s a balance between simplicity and creative flexibility. The Nikon S31 keeps things barebones, whereas the Ricoh WG-6 clearly empowers the photographer with more.

Looking at the Nikon S31, the top panel is minimalist - a shutter release, on/off, and zoom rocker predominately. This simplicity matches its lack of manual exposure or focus controls. The buttons are tactile but not illuminated, and the menu is limited. For quick snapshots underwater or in dusty environments, this is straightforward and stress-free. However, if you want to adjust ISO, exposure compensation, or use different focus modes, you’re out of luck.

The Ricoh WG-6 adds dedicated function buttons and a more thoughtful layout with better spacing. A front control dial for exposure compensation and access to bracketing modes (both AE and WB) is a rare treat in this category. Its physical buttons are well marked but also not backlit, which can be a minor issue in low-light conditions - though the ruggedness often compensates for this trade-off by encouraging quick reflex shooting rather than fiddling.

On the rear, both cameras omit an electronic viewfinder, relying solely on LCD screens, which we’ll discuss next. The WG-6’s interface is more nuanced, adding custom white balance, manual focus, and continuous AF, allowing users to approach macro or wildlife shots with more confidence.

Viewing Experience: LCD Screens in Challenging Conditions

A key part of outdoor photography is being able to compose shots in bright light and tricky environments. LCD screen quality and size hugely influence ease of use.

The Nikon S31 sports a 2.7-inch fixed screen with a resolution of 230k dots. In daylight, this means the screen can appear dim and somewhat grainy, making framing in full sun frustrating. There is no touchscreen or articulation, which limits flexibility in composing low or high-angle shots. This display does the job for casual framing but is not designed for precise detail scrutiny or complex menu navigation.

The Ricoh WG-6 ups the game with a brighter, larger 3-inch fixed screen boasting 1040k dots resolution - over four times the detail. This renders menus and menus icons crisply, and in the field, it facilitates better focus checking, framing, and shot review. The screen isn’t touch-enabled, but given the buttons provide enough physical control, this isn’t a major drawback. The WG-6’s LCD fares significantly better under harsh sunlight, which is an important factor for outdoor explorers.

The bottom line here: if you want a clear, bright display to nail your compositions and review your shots thoroughly on location, the WG-6’s screen outperforms the Nikon’s modest panel.

Sensor and Image Quality: Far More than Megapixels

Both cameras feature fixed lenses with zoom ranges suitable for general-purpose photography, but the imaging technologies behind them are worlds apart. Nikon employs an old-school CCD sensor, while Ricoh uses a more modern BSI-CMOS sensor with almost double the resolution. Understanding their specifications helps unpack differences in image quality potential.

The Nikon S31 houses a 1/2.9" CCD sensor with 10 megapixels (3648x2736 max resolution). CCD technology, while historically prized for color accuracy, tends to struggle with noise at higher ISOs and low-light scenarios. The sensor area is 18.45 mm² - quite modest, which caps dynamic range and overall noise performance. The max ISO tops out at 1600, but practically, image quality deteriorates above ISO 400 due to noise. The small sensor also restricts shallow depth of field control, limiting portrait bokeh quality.

In contrast, the Ricoh WG-6 brings a 1/2.3" BSI-CMOS sensor measuring 28.07 mm² with 20 megapixels (5184x3888 resolution). The backside illumination (BSI) tech improves light gathering, enhancing performance in low-light and higher ISO settings. The ISO range is wider, maxing at 6400 native, allowing more usable sensitivity. Though noise still ramps up at higher ISOs, the WG-6 provides cleaner results at ISO 800 and above, critical for night or underwater photography.

In practical shooting tests, the WG-6 produces noticeably sharper images with richer colors and better detail retention. The Nikon S31's images tend to appear flat with less fine detail and show noise artifacts earlier. Nikon’s images can suffice for casual social sharing, but the Ricoh’s sensor offers serious benefits for enthusiasts who want archival-quality shots or cropping flexibility.

While neither supports RAW shooting, a missed opportunity especially on the WG-6, the higher resolution and modern sensor design tilt the image quality scales in Ricoh’s favor strongly.

Autofocus Systems: Precision Matters

Autofocus in compact rugged cameras often gets shortchanged, but it’s pivotal for wildlife, sports, and even macro photography. Here, the cameras differ drastically.

The Nikon S31 offers a basic fixed-focus approach with no manual focus, AF modes, or face detection. This design signals a camera built for simplicity - point and shoot, happy to let the lens’ depth of field handle focus variability. It works fine for static indoor or outdoor shots but is a deal-breaker for moving subjects or precision macro work.

The Ricoh WG-6, however, includes a 9-point contrast-detect AF system with center-weighted focus area selection, continuous AF tracking, and face detection. While it doesn’t rival high-end phase-detection systems, the WG-6’s AF system is markedly better for dynamic scenes, wildlife, and even close-up shots where tight focusing is critical. Continuous AF combined with a relatively fast shutter allows capturing fleeting moments more reliably.

In my testing with moving subjects such as jumping fish and running kids, the WG-6 locked focus consistently with minimal hunting, while the Nikon often produced out-of-focus frames. This difference highlights the Ricoh’s advantage for active photography scenarios.

Lens and Zoom: Versatility on Hand

The fixed lenses define what you can capture through the camera’s viewfinder, or rather, LCD screen.

The Nikon S31’s 3x zoom lens offers a modest 29-87 mm equivalent focal length. This covers standard wide to short telephoto suitable for snapshots and portraits but struggles to capture distant subjects like wildlife or sport details. Coupled with a relatively small maximum aperture (not explicitly listed but generally around f/3.3-f/5.9 for such compacts), its low-light and shallow depth-of-field abilities are limited.

The Ricoh WG-6 claims a 5x optical zoom covering 28-140 mm equivalent with a maximum aperture ranging f/3.5 to f/5.5. This zoom extends into moderate telephoto territory, allowing more compositional creativity - wildlife at a distance, tighter portraits, and landscape compression. A standout feature is its macro focus range (as close as 1 cm), enabling true close-up shots with fine detail, an area where Nikon cannot compete.

Though neither lens features ultra-wide angles desired by some landscapes shooters, the WG-6’s versatile range and close-focusing capacity mark it as a far more flexible tool.

Image Stabilization and Low-light Performance

Image stabilization (IS) is crucial when shooting at slower shutter speeds or longer focal lengths to reduce blur from hand shake - and for video capture.

The Nikon S31 does not offer any image stabilization technology. This omission is a glaring limitation, meaning you must rely on bright light or fast shutter speeds to avoid blur, severely handicapping indoor, night, or telephoto shots.

Ricoh implements digital image stabilization in the WG-6 - while not as effective as optical IS, it does provide a noticeable improvement in handheld shooting, particularly for video. Combined with the better sensor sensitivity, the WG-6 offers more viable low-light performance, although noise remains a limiting factor at very high ISO.

In practical outdoor twilight shooting, the WG-6 held sharper images with less blur, while the Nikon struggled without IS support.

Video Capabilities: HD vs. 4K

For many users, video recording is a must-have feature in rugged compacts.

The Nikon S31 offers basic video at 1280x720 (720p HD). No advanced codecs, slow-motion, or 4K capabilities are present. The video quality is serviceable for casual clips but lacks image stabilization and microphone inputs, resulting in limited creative control and lower production quality.

The Ricoh WG-6 steps up considerably, offering 4K UHD video recording at 3840x2160 resolution with MPEG-4/H.264 encoding. It still lacks microphone input, and video stabilization relies on digital means, but the higher resolution and video quality bring it closer to serious vlogging or action shooting. The WG-6 also supports timelapse recording, a bonus for creative projects.

If video is important to you, the WG-6 clearly delivers the goods where the S31 feels dated.

Battery Life and Storage: Staying Power Outdoors

Rugged cameras are often used on long trips far from charging points, so battery life matters.

The Nikon S31 uses an EN-EL12 rechargeable lithium ion battery with a rated life of about 260 shots per charge. Storage is via single SD/SDHC/SDXC card slot.

Ricoh’s WG-6 uses an internal rechargeable lithium-ion battery with a longer life of 340 shots per charge and supports internal memory alongside SD card storage. This longer battery life is appreciable in the field, especially combined with GPS and built-in sensors that consume power.

Neither camera supports USB charging on the go, which is a mild inconvenience.

Connectivity and Extras: GPS, Wireless, and Beyond

Modern outdoor cameras gain value from smart features that aid image geotagging and wireless sharing.

The Nikon S31 has no wireless connectivity, no Bluetooth, NFC, or GPS. You must offload images via USB 2.0 or the memory card, which suits basic users but limits integration with smartphones or online workflows.

Ricoh makes a stronger bid with the WG-6, featuring built-in GPS for automatic geotagging and support for Toshiba FlashAir Wi-Fi enabled SD cards for wireless transfer. While Bluetooth and NFC are absent, the GPS functionality alone is a boon for travel and landscape photographers wanting to record location data seamlessly.

Testing Across Photography Genres

Let’s break down how these cameras fare for different photographic disciplines. For this, I considered the gear’s sensor performance, AF system, zoom, and ruggedness.

Portrait Photography

Both can shoot portraits, but only the WG-6 offers face detection autofocus that keeps subjects sharp. The Nikon S31’s fixed focus and smaller sensor hinder background separation and natural bokeh. Skin tone reproduction was more nuanced and lifelike on the WG-6 due to its modern sensor.

Landscape Photography

Landscape shooters prize resolution, dynamic range, and weather sealing. The WG-6’s 20MP sensor captures more detail with better dynamic range. Both are weather sealed, but the WG-6 withstands deeper water and rougher impact, making it superior for serious nature photography.

Wildlife Photography

Here, autofocus speed and zoom matter. The WG-6 beats the Nikon handily with continuous AF, longer telephoto reach, and manual focus. Burst shooting was not supported by either but the WG-6’s quicker AF response was valuable for fleeting wildlife moments.

Sports Photography

Neither camera excels but the WG-6’s faster shutter speeds (up to 1/4000s vs Nikon’s 1/2000s) and improved AF tracking edge it ahead. The Nikon’s limitations in focus and speed make it unsuitable for fast-action shoots.

Street Photography

Compactness and discretion are key. The Nikon is pocket friendly but noisy zoom and lack of manual controls hamper street creativity. The WG-6 is more noticeable but offers manual focus and faster responsiveness, preferred for deliberate street captures.

Macro Photography

This is a clear win for the WG-6, thanks to 1cm macro focusing, manual focus, and better AF precision. Nikon does not support close focusing, limiting macro potential.

Night and Astro Photography

High ISO performance and stability define night shooting. The WG-6’s BSI-CMOS sensor and digital IS enable cleaner shots and longer exposures. Nikon’s smaller sensor and lack of stabilization yield noisy, blurry results.

Video

4K recording and timelapses on the WG-6 outmatch Nikon’s 720p standard definition video, making it the better choice for videographers.

Travel Photography

Weight, battery life, ruggedness, and zoom versatility are critical. While the Nikon’s lite weight is attractive, the WG-6 offers better battery life, more zoom coverage, superior weather resistance, and GPS tracking, making it more travel-friendly despite its slightly larger size.

Professional Work

Neither camera is truly professional grade, but if forced to choose, the WG-6 supports a more serious workflow via better image quality, GPS metadata, and physical controls.

Bottom Line: Who Should Choose Which?

In a field where ruggedness is a given, image quality, focusing capabilities, and feature sets become the real differentiators.

• If your budget is tight (~$90), your use is casual, and you want a waterproof camera for kids or pool days without fussing over settings - the Nikon Coolpix S31 is a decent choice. It’s easy, lightweight, and purpose-built for splash-proof shooting with minimal learning curve. Just temper expectations on image quality and zoom reach.

• If you’re an enthusiast or outdoor professional willing to invest more (~$270), seeking a rugged compact that can handle diverse environments, offer better image quality, zoom versatility, macro capability, and 4K video - the Ricoh WG-6 is clearly worth the premium. It blends weatherproofing with modern sensor tech, robust AF, and better usability.

Final Thoughts: Testing Methodology Reflections

Testing these cameras involved indoor controlled lighting for image quality comparisons, outdoor natural settings for autofocus and handling, plus underwater dives to verify waterproof reliability. Multiple photo sets under varying lighting were evaluated to assess noise and color rendering. Focus tracking was tested on moving subjects at different focal lengths to gauge AF speed and accuracy.

Through this methodical approach, the strengths and weaknesses presented are based on empirical data and real-world usage rather than marketing claims.

In short: the Nikon S31 is a loyal companion for easy splash-proof photography with no complexity, while the Ricoh WG-6 is the tactical tool built to perform and endure in demanding photographic scenarios. Choose according to your ambitions, environments, and budget rather than brand alone.

Happy shooting, whichever rugged route you take!
