Diving Deep into the Tough: Nikon S31 vs. Ricoh WG-M1 Waterproof Cameras Compared

When it comes to waterproof cameras, ruggedness and reliability often outshine specs on paper. Yet, behind those robust shells, performance, image quality, and usability diverge widely. I’ve spent hours putting two notable underwater/ rugged compacts through their paces - the 2013 Nikon Coolpix S31 and the 2014 Ricoh WG-M1. Both target adventurous shooters, but the differences in design, imaging, and versatility are consequential.

This comprehensive comparison explores how these models hold up across photography styles - from family beach days to offbeat macro snaps and wary wildlife encounters. I’ll cut through marketing gloss and spec sheets to offer you an expert’s real-world take on what these cameras do best... and where they falter.

First Impressions: Size, Build, and Ergonomics That Matter on the Go

Size and feel aren’t minor considerations in waterproof compacts meant for spontaneous outdoor use. I immediately noticed the Nikon S31’s chunkier, rectangular grip compared to the more compact, vertically oriented Ricoh WG-M1. At 105×65×42 mm versus the WG-M1’s 66×43×89 mm, the Nikon nestles easily in broad palms, while the Ricoh’s elongated profile feels more compact but slightly awkward if you have larger hands.

Both cameras are built tough, but with contrasting approaches: Nikon’s Coolpix S31 touts waterproofing down to 10 meters, shockproofing from 1.5 meters, dustproofing, and freeze-proofing - ideal for chilly, harsh environments. The Ricoh WG-M1 matches with waterproofing up to 10 meters, shockproofing from 2 meters, but it lacks dust or freeze protection. That’s an important factor if you plan arctic diving or desert adventures.

Handling-wise, neither offers a physical viewfinder; reliance on LCD screens means legibility and responsiveness are critical. The Nikon’s 2.7" fixed screen (230k dots) is pleasantly larger than Ricoh’s compact 1.5" 115k dot display.

Controls on the Nikon are straightforward but limited - big buttons with no illuminated functions, reflecting its “point-and-shoot” design philosophy. The Ricoh, though minimalist, benefits from a higher continuous shooting rate and wireless connectivity, marked clearly on a top button cluster.

Under the Hood: In-Depth Sensor and Image Quality Breakdown

Sensor technology is the heart of any camera’s imaging prowess. Here, the Ricoh WG-M1 enjoys an edge with its 1/2.3" CMOS sensor boasting 14 megapixels and a sensor area of 28.07 mm², comfortably larger than the Nikon S31’s 1/2.9" CCD sensor at 10 megapixels and 18.45 mm² sensor area.

Why does this matter? Larger sensors and CMOS tech generally translate to better low-light capabilities and dynamic range. Despite this, the Nikon’s CCD sensor performs reasonably well under bright daylight but struggles noticeably when shadows deepen or ISO rises above 400. The Ricoh, meanwhile, maintains cleaner images up to ISO 800 - its max native ISO - though noise becomes evident beyond that.

Both cameras incorporate an anti-aliasing filter and shoot JPEG only, lacking RAW support - a major drawback for serious photographers who crave post-processing latitude. Still, for casual outdoor use, JPEG delivers acceptable files, especially from the Ricoh’s more detailed 4320×3240 images versus Nikon’s max 3648×2736 resolution.

Viewing and Interfaces: Screen Quality and Usability in the Field

Compact chargers that forgo viewfinders place the spotlight on rear screens for composition and review. The Nikon S31’s larger 2.7" screen makes framing scenes and reviewing shots easier compared to Ricoh’s diminutive 1.5" display. Both lack touch capability and high resolution - at 230K and 115K dots respectively - so fine details in menus or photos can be elusive under bright sunlight.

Neither offers physical manual controls beyond basic exposure modes, sticking to simplicity - no aperture/shutter priority, no custom white balance (except Ricoh’s basic WB bracketing), no manual focusing. This makes them friendly for beginners or swimmers who want quick shots but limits artistic control.

Beyond Stills: Video Capabilities That Can Capture Your Adventures

If you want to film your underwater escapades or sports antics, there’s a clear winner. The Ricoh WG-M1 supports Full HD 1080p video at 30 fps with H.264 compression, also offering ultra-smooth options like 960p at 50 fps or 848x480 at 120 fps for slow-motion.

The Nikon S31, limited to 720p HD video at 30 fps, lacks advanced video features or external mic input, hampering professional-level filmmaking.

From my tests, Ricoh’s footage was noticeably crisper and more detailed; it handled motion better without excessive rolling shutter artifacts. Both cameras omit image stabilization (optical or electronic), so handheld video can be shaky - a critical consideration for active videographers.

Toughness Test: Environmental Resilience and Reliability

Both cameras come rated as rugged, but with meaningful distinctions. The Nikon S31’s dustproof and freezeproof protection means it can safely tag along in desert winds or winter frosts - a valuable plus I rarely see in compact waterproofs.

Ricoh’s WG-M1 excels with its shockproofing tested to a higher 2-meter drop (Nikon claims 1.5m), appealing to hikers or mountain bikers worried about accidental falls.

Neither is crushproof, so don’t expect them to survive vehicle compression or heavy loads. But for swimmers, snorkelers, or kids, these models provide peace of mind.

Autofocus and Shooting Performance: Speed, Accuracy, Burst Modes

Both cameras lack sophisticated autofocus systems. Nikon’s S31 provides no continuous or tracking autofocus; it relies on simple fixed point contrast detection with an unknown number of focus points, limiting its ability to lock onto moving subjects.

Ricoh’s WG-M1 uses contrast detection focus but offers a burst shooting mode at a brisk 10 frames per second, highly useful for capturing spontaneous wildlife or sports moments. I found Ricoh more reliable and responsive when quickly acquiring focus in daylight conditions compared to Nikon’s hesitant AF.

Neither camera offers face/eye detection or advanced AI focus modes - no surprises given their entry-level credentials.

Lenses, Zoom, and Magnification: Versatility for Different Subjects

The Nikon S31 sports a 3× optical zoom covering 29-87mm equivalent focal length with a 7.3× crop factor. While this range supports wide-angle shots and short telephoto portraits, its relatively long minimum focal length means true wide vistas can be tricky to capture.

Ricoh’s WG-M1 fixed lens has a 1× focal length (5.8× crop factor), essentially a fisheye or ultra-wide setting. This wide angle is perfect for action and underwater shots but lacks zoom versatility.

Neither camera features optical image stabilization; without it, zoomed or macro shots risk softness due to handshake - especially in low light.

Battery and Storage: Longevity When You Need It Most

Battery endurance is always pivotal - you can’t shoot if your camera’s out of juice deep in the wild. Ricoh wins here with a 350-shot rated life (using its DB-65 battery), while Nikon offers a modest 260 shots per charge with the EN-EL12 pack.

Storage-wise, Nikon supports SD/SDHC/SDXC cards whereas Ricoh requires microSD/microSDHC cards and includes some internal memory - a plus if you forget a card. Neither has dual slots, so carry backups.

Connectivity and Extras: Wireless and Interface Features

Here the WG-M1 pulls ahead: it includes built-in Wi-Fi for wireless image transfer and remote control via smartphone apps. This is a welcome convenience if you want to offload shots quickly or trigger the camera when mounted remotely.

Nikon S31 lacks any wireless features and has only USB 2.0 connection - making it feel a bit dated in an era of instant sharing.

Neither have Bluetooth, NFC, GPS, or headphone/mic jacks, reflecting their basic nature.

Real-World Photography: Comparing Image Quality and Style Across Genres

To ensure a well-rounded assessment, I tested both cameras across the major photography types important to enthusiasts and professionals using rugged waterproof compacts.

Portraits

Neither camera is optimized for portraits given lack of aperture control and minimal zoom. The Nikon’s 29-87mm range allows some framing flexibility but the lack of face detection AF and modest sensor resolution limit subject separation and bokeh quality. Skin tones tended toward flatness, especially indoors.

Ricoh’s wider lens distorts features close up, making it less flattering for portraits but fun for candid environmental shots.

Landscapes

Ricoh’s ultra-wide-angle lens and superior resolution produce more compelling landscapes, with greater sharpness and detail captured in daylight. However, both cameras lack HDR or advanced dynamic range capabilities, and their small sensors lose shadow detail in challenging lighting.

Weather resistant bodies on Nikon help for rugged environments, while Ricoh’s shockproofing encourages active shooting.

Wildlife

Ricoh’s 10 fps burst and swift AF give it a clear advantage in capturing quick animal movements. Nikon’s slow focus and no burst capability make it ill-suited for dynamic subjects.

Neither have telephoto reach necessary for distant wildlife; both best used for close encounters.

Sports

Again, Ricoh dominates with continuous shooting and video options. Nikon S31’s top shutter speed and lack of burst severely limit fast action shooting.

Street Photography

Portability favors Ricoh, whose compact size and wide lens lend to discreet shooting. However, Nikon’s bigger body and screen aid quick reframing and reviewing in variable urban light.

Macro

Neither excels at macro due to minimum focusing distances and lack of specialized lenses or focus stacking - but in bright conditions, Ricoh’s sharpness and wide field give interesting close-ups of flowers or textures.

Night and Astrophotography

Small sensors and max ISO limits restrict long exposure potential. Both cameras struggle with noise and lack manual exposure control, so these genres are best avoided.

Travel

Battery life, ruggedness, and easy usability rank crucial here. Nikon’s environmental seals and freezeproofing appeal to cold climates, Ricoh’s Wi-Fi and video prowess suit dynamic travel blogging.

Professional Use

Neither camera supports RAW, advanced manual controls, or external accessories, making them unsuited for pro workflow integration. Their value lies more in casual, rugged use.
