Pentax WG-2 vs Ricoh WG-5 GPS: A Deep Dive into Rugged Compact Waterproof Cameras

In the niche but persistently popular category of rugged waterproof compact cameras, the Pentax WG-2 and the Ricoh WG-5 GPS stand out as compelling contenders. Each model delivers a unique blend of toughness, versatility, and imaging capabilities tailored for photographers who demand more than just a simple point-and-shoot - whether you’re exploring wild landscapes, shooting underwater life, or capturing fast-moving subjects in unpredictable weather.

Having logged hours of hands-on testing with both cameras over varied real-world scenarios, I’m ready to unpack their strengths and weaknesses. This comprehensive comparison will illuminate which model shines in different photography disciplines and practical applications. Whether you’re an outdoor enthusiast, a travel photographer, or seeking a backup rugged shooter to your main rig, this detailed analysis will help you make an informed choice.

Toughness and Ergonomics: Built to Brave the Elements

Both the Pentax WG-2 and the Ricoh WG-5 GPS are engineered to withstand punishing conditions - waterproof, shockproof, freeze-proof, and crushproof specifications underpin their rugged personas. However, they approach this ruggedness with slightly different design philosophies.

Pentax WG-2:

• Dimensions: 122 x 61 x 30 mm
• Weight: 192 g
• Environmental sealing: Waterproof (up to 40 ft), dustproof, shockproof, crushproof, freezeproof

Ricoh WG-5 GPS:

• Dimensions: 125 x 65 x 32 mm
• Weight: 236 g
• Environmental sealing: Waterproof (up to 40 ft), shockproof, crushproof, freezeproof - but notably not dustproof
• Built-in GPS module

The WG-2 is marginally lighter and a touch more compact, which translates into better handling for extended handheld use, especially in travel and street photography where every gram counts. The rubberized grip texture and button placement feel deliberate, giving confident control even in wet or gloved hands.

The WG-5 GPS, slightly heavier and chunkier, feels more substantial but less pocketable. The added weight is partially due to the onboard GPS hardware and integrated sensor-shift image stabilization (more on that later). I appreciate the WG-5’s button layout for quick adjustments in the field - though the buttons are a bit stiffer and less tactile compared to the WG-2's.

Both lack viewfinders, which is typical in this rugged compact segment, so you’ll be framing exclusively via their LCDs.

Controls and User Interface: Navigating Your Adventure

With compact cameras aimed at adventure photographers, thoughtful control layout and intuitive menus are paramount - as you’ll often have to make quick adjustments in challenging conditions.

Both have fixed 3-inch LCD screens at 460k-dot resolution, lacking touch capability, but delivering bright, clear live view. The Pentax’s buttons are logically arranged around a directional pad, allowing access to ISO, white balance, macro mode, and burst shooting in just a couple of clicks. The mode dial is straightforward but limited - no aperture priority or manual exposure modes here.

Ricoh WG-5 GPS continues to offer the mode dial, but adds shutter priority exposure mode, which enthusiasts will appreciate for more control over motion blur in sports or wildlife shooting - a definite plus. Also, the WG-5 features customizable buttons, so you can map your frequently used functions, which boosts operational efficiency.

A minor gripe both share is the lack of illuminated buttons, which hinders night-time usability without external light. Also, neither camera sports a top status screen, which some photographers miss for quick glance info in varying conditions.

Viewing Experience: LCDs Under Scrutiny

In daylight, both cameras’ LCDs perform admirably, with decent anti-reflective coatings and wide viewing angles, despite the modest 460k resolution - which is par for the course in rugged compacts. The Pentax WG-2’s screen has a slight advantage with its anti-reflective coating, making it easier to compose shots under harsh sunlight.

Ricoh’s WG-5 GPS does not specify a similar coating but competes strongly with high brightness and contrast. The lack of a touchscreen means all manual focus or exposure tweaks are done with buttons - a speed bottleneck compared to modern hybrid touch interfaces, but understandable given the rugged emphasis.

Imaging Core: Sensor Technology and Image Quality

Both cameras feature a 1/2.3-inch BSI CMOS sensor with an effective resolution of 16 megapixels. This sensor size is typical for rugged compacts, offering a balanced compromise between compactness and decent resolution, although it cannot rival larger sensors in dynamic range or noise control.

The WG-2’s sensor maxes out at 4288 x 3216 pixels, whereas the WG-5 pushes slightly higher resolution at 4608 x 3456 pixels - a tangible advantage when cropping or printing large images is a priority.

Despite nearly identical sensor areas (roughly 28.07 mm²), the WG-5 benefits from a faster maximum aperture (F2.0 at wide-angle vs. F3.5 on the WG-2), allowing for more light capture and better low-light performance - a critical feature when shooting indoors or under dense canopy.

From daylight landscape tests to low-light indoor shooting, I found the WG-5’s images cleaner at higher ISOs and more vibrant thanks to updated processing algorithms. The WG-2 suffices for general use but struggles with noise beyond ISO 800, whereas the WG-5 maintains usable files through ISO 1600, critical for night and astro photography.

Neither camera supports RAW files, a limitation for professionals and enthusiasts who want maximum post-processing flexibility. JPEG compression artifacts become visible with heavy editing, so users should aim for careful exposure in-camera.

Field Test: Image Quality Comparison

Examining sample images across a variety of genres, the WG-5 GPS stands out in:

• Portraits: Softer bokeh due to the wider f/2.0 aperture helps subject separation and pleasing skin tone rendition with accurate exposure and face detection autofocus. WG-2 is respectable but less flattering in shallow depth of field.

• Landscape: Both capture rich detail at wide angle, but WG-5’s improved dynamic range preserves highlights and shadows better on sunny days. The WG-2’s shots occasionally clip highlight detail in bright sky areas.

• Wildlife & Sports: WG-5 benefits from faster burst shooting (14 fps vs 1 fps on WG-2) and continuous autofocus - essential for tracking fast animals or athletes. WG-2 can’t keep pace here.

• Macro: Both excel at close focusing down to 1cm, but WG-5’s image stabilization helps keep handheld macro shots sharp.

• Night/Astro: WG-5’s stronger high ISO and longer exposures produce more usable hand-held star fields and ambient landscapes. WG-2 struggles in these settings.

Thus, for pure image quality and versatility, the WG-5 GPS has a decisive edge.

Autofocus and Burst Performance: Keeping Pace with Action

Autofocus systems can make or break experience with dynamic subjects.

• Pentax WG-2: Contrast-detection AF with 9 focus points, face detection, but no continuous AF or AF tracking in burst mode. This makes capturing fast-moving subjects challenging.

• Ricoh WG-5 GPS: Also contrast detection with 9 AF points, but intelligently adds continuous AF and focus tracking. Combined with burst shooting up to 14 fps, this makes WG-5 superior for wildlife and sports photography.

While neither camera matches the advanced phase-detection AF systems of mirrorless or DSLRs, WG-5’s inclusion of AF tracking is a significant practical bonus in unpredictable shooting scenarios.

Lens and Optical Considerations

Both cameras feature fixed zoom lenses with a 5.8x focal length multiplier but slightly different ranges:

• WG-2: 28-140 mm equivalent, aperture F3.5-5.5
• WG-5 GPS: 25-100 mm equivalent, aperture F2.0-4.9

The WG-5’s wider aperture at the short end allows better light capture - ideal for low-light environments or creative depth of field. The slightly shorter telephoto reach on WG-5 may hamper reach somewhat for distant subjects, but the trade-off favors versatility and sharpness.

Neither supports external lenses or filters - a common limitation in compact waterproof models - but both offer decent macro focus starting at 1 cm.

Stabilization: The WG-5 GPS Advantage

Perhaps the biggest difference in real-world handling is the presence of sensor-shift image stabilization on the Ricoh WG-5 GPS. Via gyroscopic sensors and micro-motors, it compensates for hand-shake, allowing sharper photos at slower shutter speeds.

The WG-2 lacks any image stabilization, which becomes apparent especially in low-light and macro photography - where minor movements magnify blur. I found the WG-5’s stabilization effective in allowing handheld shooting at 1/8 second exposures where the WG-2 would require a tripod.

For video users, this translates into smoother footage as well.

Video Capabilities: Full HD, But No 4K

Both cameras shoot Full HD 1080p video, with a maximum frame rate of 30 fps. They also offer 720p at 60 fps for smoother motion capture.

Neither supports 4K or high frame rate slow motion modes, which curtails appeal for serious video shooters. Microphone and headphone ports are absent, limiting audio control.

Video quality is solid for action and travel diaries, though rolling shutter and compression artifacts appear on fast pans.

Battery and Storage: Everyday Practicalities

Both use the same battery pack type (D-LI92), with rated battery lives around:

• WG-2: 260 shots per charge
• WG-5 GPS: 240 shots per charge

This minor difference is reasonable given WG-5’s GPS and stabilization systems consuming more energy.

Both cameras use SD/SDHC/SDXC cards; a single card slot with support for internal memory as backup. USB 2.0 and HDMI ports are standard on both for file transfer and external viewing.

Wireless connectivity varies: WG-2 supports Eye-Fi wireless card integration but lacks Bluetooth or Wi-Fi, limiting instant sharing. The WG-5 GPS has no wireless but includes built-in GPS - a big plus for geotagging adventurous shoots.

Specialized Features: GPS and Timelapse

Ricoh’s WG-5 GPS’s onboard GPS sensor is a standout for outdoor photographers who want automatic geotagging without extra devices. It also integrates well with Ricoh’s smartphone apps for mapping your shooting locations.

Both cameras offer timelapse recording - handy for landscape and astrophotography projects - though WG-5 permits more flexible interval settings.
