Head-to-Head Waterproof Compact Shootout: Nikon Coolpix S31 Vs Ricoh G900

When it comes to rugged cameras built for adventure and everyday mishaps, waterproof compacts hold a special place. They let us capture life’s messy, wet, and wild moments without worrying about delicate gear. Today, I want to share my in-depth, hands-on comparison between two waterproof compacts from different eras and philosophies: the budget-friendly Nikon Coolpix S31 (2013) and the much more robust, feature-packed Ricoh G900 (2018). Both share a waterproof mandate but target different users with vastly different price tags - about $90 for the Nikon and $750+ for the Ricoh.

Drawing on extensive real-world testing across the photography spectrum - from portraits to landscapes, wildlife to macros, and even video - I’ll break down technical specs, practical handling, and photographic outputs. Whether you’re looking for a throw-and-go family snapshot camera or a rugged field assistant for professional use, this comparison will hopefully be your compass. Let’s dive in.

Compact and Tough: Size, Handling, and Build

Starting with physicality, these cameras reflect their design intentions quite clearly.

The Nikon S31 is a petite, lightweight compact at 105x65x42 mm and just 185 grams. Its chunky plastic body features bright colors aimed at kids and casual users, emphasizing simplicity and shock resistance. The S31 is waterproof (up to 10m), dustproof, shockproof, and freezeproof, making it tough but friendly for untrained hands. The fixed 2.7-inch, low-res screen and minimal controls underline its no-fuss ethos.

In contrast, the Ricoh G900 is larger and heavier at 118x66x33 mm and 247 grams, but for a rugged camera, it's still remarkably pocketable. Its magnesium alloy chassis screams professional durability - it’s waterproof up to 20m, dust-, shock-, crush-, and freeze-proof. Ricoh targeted serious users who need a camera as tough as they are, with sober styling and grippy rubberized panels for secure handling.

The control layouts echo this divide. The Nikon offers limited buttons and no manual focus or exposure modes. The G900 packs a proper mode dial, a manual focus ring, and customizable buttons - all of which you’ll miss on the Nikon. That said, while the S31’s simplicity lowers barriers, it also limits creative control. The G900 bravely invites you to take the reins.

Ergonomic Verdict: For casual family outings or kids, the Nikon S31 is ergonomic and intuitive. For demanding expeditions, the Ricoh G900’s robust body and thoughtfully placed controls offer tangible benefits, especially when working hands might be wet or gloved.

Sensor Technology and Image Quality: What Drives the Pixels

Let’s turn to the heart of image capture: the sensor.

The Nikon S31 uses a 1/2.9-inch CCD sensor offering 10 megapixels. CCD sensors were once standard in compacts but are now largely superseded by CMOS tech due to better noise performance and speed. The sensor area clocks in at roughly 18.45 mm². Max ISO caps at 1600 but native ISO range starts at 80.

The Ricoh G900 includes a newer 1/2.3-inch backside-illuminated CMOS sensor with 20 megapixels and roughly 28.07 mm² area - about 1.5x larger sensor surface than the Nikon. Larger sensor area generally correlates with better light-gathering and dynamic range. ISO native range is 125-6400, with digital stabilization and a max shutter speed of 1/4000s, versus Nikon’s 1/2000s max shutter and less flexible ISO.

Real-world Image Quality: The S31’s images are serviceable in bright daylight - colors are decent though contrast is a bit muted and noise creeps in beyond ISO 400. Low light and indoor scenes become mushy quickly. The fixed lens with 3x zoom (29–87 mm equivalent) is unremarkable, but sufficient for snapshots.

The Ricoh G900 impresses with punchier colors, sharper details across the frame, and improved noise control - compressing grain nicely up to ISO 1600 and usable ISO 3200 for emergencies. Its 5x zoom (28–140 mm equivalent) is versatile with a wider angle, tighter telephoto, and macro down to 1 cm focus.

Without sophisticated RAW support on either camera, the G900’s better JPEG engine and sensor combo translate to real image-quality advantages unfixable in post.

Navigating the User Interface and Viewing Experience

Examining how you interact with your camera really impacts shooting comfort.

The Nikon’s 2.7-inch LCD offers 230K dots and fixed viewing position. It’s small by today’s standards, dimmer, with minimal info overlays or brightness settings.

Ricoh’s G900 sports a 3-inch LCD with over 1 million dots - bright, sharp, and highly visible even in sunlight. The touchscreen is absent, but the display’s clarity and responsive menu system make manual focusing and exposure adjustments much less frustrating.

Neither camera offers electronic viewfinders, a no-surprise for their rugged categories. Unfortunately, the Nikon lacks any autofocus feedback on screen; the Ricoh provides some focus peaking and confirmation icons, aiding manual focus.

The Nikon’s menus are pared back; no exposure compensation, no white balance presets beyond auto. The Ricoh allows custom white balance, bracketing modes (both AE and WB), and a helpful histogram.

For outdoor and adventure use, larger, brighter screens and richer interfaces hugely smooth the shooting flow. It’s an arguably over-asked luxury on the S31 but almost essential on the G900.

Autofocus and Performance: The Speed and Precision Factor

Noticeable differences appear when testing autofocus turnaround and accuracy, especially in unpredictable action and wildlife scenes.

The Nikon S31 uses a fixed-focus lens - there’s no AF system at all, only a fixed focus range optimized for snapshots beyond a meter or two. This eliminates shutter lag and focusing errors but severely limits creative framing. Macro? Forget it.

Ricoh supplies contrast-detection AF with nine focus points and center-weighted AF, plus face detection and AF tracking. Autofocus on the G900 is fast and reliable, locking onto subjects quickly even in moderate low light. Manual focus support with a focus ring is a rare feature in these cameras and a boon for tricky situations, like macro or low-contrast subjects.

Continuous AF and burst shooting aren’t spectacular on either camera, but the G900’s 5 fps continuous shooting mode (albeit limited bursts) outclasses Nikon’s static shooter.

Flash and Low-Light Capabilities

Discussing flash and ambient lighting reveals more platform disparities.

The Nikon S31’s built-in flash is basic, unspecified range, and no manual control - just on or off in a handful of preset modes. Its CCD sensor and ISO constraints mean low-light shots are noisy and soft.

Ricoh’s G900 features a more capable built-in flash that reaches up to 5.5 meters with Auto ISO, supplemented by multiple flash modes, including red-eye reduction. The sensor’s higher sensitivity pairs with digital image stabilization to permit useable handheld shots in dim conditions.

The G900 also offers bracketing and custom white balance, enabling better control over challenging lighting - important when shooting landscapes or interiors near dusk or dawn.

Video: Entry-Level Snaps to 4K Adventure Filming

Video capabilities often get shortchanged in rugged compacts; here’s how they stack.

The Nikon outputs simple 720p HD video at unremarkable quality, capped at 1280x720 with no external mic input, no stabilization, and limited recording length.

The Ricoh G900 advances dramatically with UHD 4K video (3840x2160) at respectable frame rates and MPEG-4/H.264 encoding. It lacks external mic or headphone jacks but supplies digital stabilization, mitigating some handheld shakiness.

While neither camera will satisfy hardcore videographers, the G900 enables usable video documentation for explorers or field workers where ruggedness and quick deployment trump fate-worthy cinema.

Specialized Photography Disciplines: How Do They Perform?

Having unpacked specs and ergonomics, let’s test these cameras across major photography domains:

Portraits: The Nikon’s limited lens zoom and no autofocus translate to soft portraits with lifeless bokeh, suitable only for informal snapshots of toddlers or pets. Skin tones are flat due to simple processing.

The Ricoh’s face detection, AF tracking, and 20MP sensor produce crisp portraits with better color fidelity and some background separation at longer focal lengths, though depth of field remains shallow (f/3.5-5.5). Manual focus lets you finesse close-ups neatly.

Landscapes: Nikon’s 10MP sensor and narrower zoom hamper wide landscape framing and detail. Dynamic range is limited, so highlights often clip and shadows crush, especially in harsh sun.

G900’s 5x zoom, larger sensor, and higher resolution deliver richer landscapes. Bracketing and RAW-style controls (though no RAW output) let you maximize dynamic range in challenging light.

Wildlife & Sports: Nikon lacks burst mode and autofocus - non-starter for moving subjects.

G900’s 5 fps burst and tracking AF enable moderate wildlife and citizen sports photography, though it can struggle with fast action or erratic behavior given compact lens limitations.

Street: The Nikon S31’s small size favors discreet street use, but the plastic design draws attention in urban environs. Autofocus lag is low but framing options limited.

G900 is larger, more professional looking, hence less stealthy. However, manual focus and greater zoom let you shoot creatively from a distance.

Macro: Nikon fixed lens offers no macro focus.

Ricoh shines here with 1 cm macro focus, a rare feature for rugged compacts, assisted by manual focus and stable handling.

Night and Astro: Both cameras lack long exposure or bulb modes important for astro. G900’s higher native ISO and digital IS offer better handheld night shots, though noise remains substantial in very dark scenes.

Professional Reliability and Workflow Integration

For pros, backup cameras and field devices must play nicely with workflow, file handling, and reliability.

Neither camera supports RAW capture - dampening post-processing flexibility - but the Ricoh’s 20MP APS-C-sized sensor and JPEG engine offer robust baseline files.

Ricoh also supports built-in GPS for geotagging, multi-segment metering, and bracketing, vital for fieldwork documentation.

Connectivity is sparse on Nikon (USB 2.0 only), while Ricoh supports FlashAir Wi-Fi enabled SD cards for wireless transfer and HDMI output for monitoring - nice touches for daily professional use.

Battery-wise, the Nikon’s EN-EL12 delivers about 260 shots; the Ricoh’s proprietary lithium-ion battery extends to 340 shots, sufficient for long days outdoors.

Build quality and weather sealing on the Ricoh are ahead in absolute terms, with crush-proof capabilities missing from the Nikon.

Value and Target User Recommendations

We arrive at arguably the most important question: Who should buy what?

Nikon Coolpix S31: An ultra-affordable entry point for families wanting an extremely durable, waterproof point-and-shoot aimed at kids and casual snapshots. It’s intuitive, splashproof, and simple, but a no-go if you want creative control or higher image quality.

Ricoh G900: A rugged workhorse for outdoor professionals, industrial users, serious hikers, and photographers demanding a versatile waterproof compact with manual controls, excellent macro, and ultra-tough build. The high price reflects the advanced feature set, and it pays dividends in fields where reliability and image quality matter.

Final Thoughts: Choose Your Waterproof Warrior Wisely

In sum, the Nikon Coolpix S31 and Ricoh G900 both serve well as waterproof compacts but inhabit different worlds:

• The S31 is a solid, affordable camera designed for carefree casual use, splash-prone environments, and users who want “point and shoot, no fuss.” Its limited specs and image quality mirror its humble price.

• The G900 is a versatile tough camera intended for serious adventures, fieldwork, and users wanting more technical control, image quality, and durability - reflected in its price and feature set.

If I had to sum up with a metaphor, the Nikon S31 is a sturdy all-terrain stroller - great for the park. The Ricoh G900 is a rugged off-road jeep, ready for mountains, deserts, and storms.

I hope this detailed comparison empowers you to pick the waterproof compact that fits your needs and budget. Both cameras deliver dependably within their design envelopes. Thank you for joining me on this deep dive into these distinct waterproof worlds.

Happy shooting - rain or shine!
