Pentax WG-3 GPS vs Ricoh WG-5 GPS: The Ultimate Waterproof Compact Camera Showdown

When it comes to rugged, waterproof compacts, both Pentax and Ricoh have carved out loyal followings among adventurers and casual shooters alike. Their WG series cameras - a niche blend of toughness, portability, and versatility - are designed to thrive where conventional cameras fear to tread. Here, I put the Pentax WG-3 GPS head-to-head with the Ricoh WG-5 GPS, pouring in hundreds of hours of hands-on testing along versatile shooting scenarios to uncover how each stacks up in usability, image quality, durability, and overall value.

Whether you're diving reef-side, hiking mountain trails, or just want a dependable point-and-shoot that laughs off bad weather, this comparison offers you a thorough exploration of their strengths and tradeoffs - with recommendations tailored to your photographic priorities.

Getting Physical: Size, Handling, and Ergonomics

Size and grip feel are surprisingly important considerations for cameras designed for tough environments. Both these models stick to the classic waterproof compact footprint, but subtle differences affect day-to-day handling.

• Pentax WG-3 GPS measures 125 x 64 x 33 mm and weighs 238 grams.
• Ricoh WG-5 GPS is nearly identical at 125 x 65 x 32 mm, just marginally lighter at 236 grams.

Despite near-identical dimensions, I found the WG-5 GPS felt a bit more balanced in hand, thanks to its slightly contoured grip and button placement. The WG-3’s control surfaces felt a touch more cramped, particularly for photographers with bigger hands or when using gloves in cold conditions.

Both cameras are rated highly for durability: waterproof to depths of 14 meters (WG-3) and 14 meters (WG-5), crushproof, shockproof, and freezeproof - catering equally well to outdoor and underwater shooting.

Control Layout and Top View Usability

Top-down control design influences quick access for shooting adjustments - especially vital when you can't fiddle around on menus in the field.

• The WG-5 GPS adds Shutter Priority exposure mode, absent in the WG-3, letting you control shutter speed for creative effects.
• Both cameras sacrifice full manual controls, appealing mostly to enthusiasts seeking rugged simplicity rather than pro-level customization.

Buttons are tactile and responsive, though the WG-5’s layout edges out the WG-3 slightly by grouping ISO, flash, and drive modes more intuitively. The illuminated button backlighting remains absent on both, a drawback in low-light shooting, but reasonably offset by their bright rear LCD readability.

Sensor & Image Quality: Identical Starts?

Both cameras share the same sensor type and size:

• 1/2.3" BSI-CMOS sensor, 16 megapixels, sensor area 28.07 mm²
• Native ISO of 125 to 6400, with the standard anti-aliasing filter

The sensor similarity means base image quality and resolution are very close. That said, image processing engines and lens sharpness do create subtle differences in real-world results.

In my testing:

• The WG-5 offers better high ISO noise control, extending usable ISO marginally above the WG-3. Noise starts to degrade images in WG-3 above ISO 1600, whereas the WG-5 maintains cleaner files up to ISO 3200.
• Both cameras struggle with dynamic range typical of small sensors, but the WG-5’s slightly improved JPEG rendering and exposure bracketing options provide better highlight and shadow recovery in challenging lighting.

For landscape shooters chasing wide tonal range and maximum clarity, neither will replace a mirrorless or DSLR, but the WG-5’s marginal gain in noise and bracketing lends it a modest edge.

Rear LCD Screen and User Interface

A usable, clear screen is vital for composing shots in bright outdoor conditions or underwater.

Both boast a 3-inch fixed type LCD with 460k dot resolution and an anti-reflective coating. I found the sharpness and color accuracy similar, though the WG-5’s screen seemed slightly brighter, improving visibility in direct sunlight - a boon for outdoor photography.

Neither model uses a touchscreen interface, meaning menu navigation and focus selection rely on buttons alone. Honestly, this tradeoff favors reliability against water ingress, but can frustrate users used to touch control speed.

Interface-wise, both cameras use a straightforward menu system with logical grouping. The WG-5 benefits from enhanced autofocus options, making navigation marginally smoother.

Autofocus Performance Across Photography Genres

Autofocus is a critical performance pillar, particularly for action, wildlife, and street photography.

The WG-5 GPS shines more here due to its continuous autofocus during burst shooting and live view capabilities, allowing you to better track moving subjects like wildlife or sports competitors. In the WG-3, AF remains single shot only, making sequence capturing less fluid.

Face detection performs reliably on both, with neither offering animal eye AF - a feature still rare at this price tier. For portraits, the cameras perform comparably but the WG-5’s AF responsiveness delivers a smoother shooting experience with fast-moving kids or pets.

Burst Rate and Continuous Shooting

Burst shooting rates impact your ability to capture decisive moments in wildlife and sports.

• WG-3 GPS does not specify a continuous shooting speed, effectively limiting burst usage.
• WG-5 GPS impresses with a 14 fps continuous shooting mode, albeit at 3MP resolution.

The WG-5’s fast burst, albeit at reduced resolution, enables photographers to effectively capture rapid action sequences - a clear plus for sports and wildlife enthusiasts.

Flash and Low Light Performance

Both include a built-in flash, but the WG-5 GPS takes a lead here with a significantly longer flash range: 10.4 meters at Auto ISO, compared to the WG-3’s 3.4 meters. This difference enhances fill light usefulness for portraits and night scenes.

Low light performance beyond flash also favors the WG-5 due to improved sensor processing and image stabilization effectiveness.

Environmental Sealing: Built to Brave the Elements

Both cameras live up to their 'Waterproof' category labels with rugged construction:

The WG-3's dustproof design gives it a slight advantage when shooting in desert or dusty locations.

For most practical applications - from trekking to scuba diving - both cameras promise high durability. The WG-5 sacrifices dustproofing in favor of slightly refined ergonomics and internal component upgrades.

Video Capabilities and Multimedia

Both cameras shoot full HD video at 1920x1080/30fps, alongside HD at 1280x720/60fps, encoded in MPEG-4 and H.264.

• Neither supports 4K or advanced video features like log profiles.
• No external microphone input or headphone jack limits control over audio quality.
• Both provide timelapse recording modes, useful for creative finalists.

The WG-5 GPS autofocus continuous during video - absent in WG-3 - making it better suited to handheld video applications, for example, documenting outdoor adventures.

Stabilization, Macro, and Special Shooting Modes

• Both cameras use sensor-shift image stabilization assisting handheld shooting.
• Macro focus at 1 cm enables close-up shooting, a great feature for macro enthusiasts.
• WG-5 supports exposure bracketing and white balance bracketing; WG-3 does not, enabling greater creative flexibility.
