Pentax WG-2 GPS vs Ricoh WG-6: A Deep Dive into Waterproof Tough Cameras

When it comes to rugged, waterproof compact cameras, enthusiasts and professionals often turn to specialized models designed to survive extreme environments. The Pentax Optio WG-2 GPS and the Ricoh WG-6 represent two compelling options in this niche, offering weather sealing, durable construction, and a suite of features tailored for outdoor photography. Though they share a similar heritage and target audience, these cameras differ in many significant areas that impact real-world usability and image quality.

Having spent countless hours of hands-on time with tough cameras across various environments - from underwater reef dives to snowy mountain treks - I bring an informed perspective to help you understand which of these two models might better fit your shooting style, technical demands, and budget considerations. Let’s jump in.

First Impressions: Design, Build, and Ergonomics

Before you shoot a single frame, the way a camera feels in your hands profoundly influences the shooting experience. Both the WG-2 GPS and WG-6 claim ruggedness, but their form factors and handling nuances tell different stories.

At a glance, the Pentax WG-2 GPS is a slightly lighter and slimmer unit, weighing 198 grams against Ricoh’s 246 grams. Measuring 122 x 61 x 30 mm versus 118 x 66 x 33 mm, it’s marginally more compact but also a tad narrower. This translates into a slightly more pocket-friendly profile, which is a boon for hikers, travelers, and street photographers seeking discreet durability.

The Ricoh WG-6’s extra heft and girth contribute to a more substantial grip surface and increased perceived durability. Its wider and thicker dimensions accommodate slightly larger button placements and a tougher chassis, important for those who work in harsh conditions and want confidence that their gear won't falter. Additionally, the WG-6's textured grips and rubberized surfaces provide a sure hold even with wet or gloved hands.

The ergonomics showcase Ricoh’s evolution within the WG series lineup, emphasizing ruggedness and comfort over extreme compactness, while the Pentax WG-2 GPS sticks to a more traditional compact footprint.

Looking from above, both cameras sport straightforward control schemes with fixed lenses. The WG-2 GPS keeps things minimal with simple mode dials and shutter controls, though its buttons feel a bit smaller and more cramped - a trade-off for its slight size advantage. Ricoh’s WG-6 arms you with larger, well-spaced buttons, including a dedicated function key that can be customized for quicker access to frequent settings. This makes it more intuitive to operate quickly in the field, important when shooting wildlife or sports where moments vanish in a blink.

Both cameras come without an electronic viewfinder, relying solely on their LCD screens for framing and review, a factor I will explore further.

Sensor and Image Quality: Tiny Sensors, Big Differences

Under the skin, neither camera sports a large sensor by today’s standards - both employ identical 1/2.3-inch BSI-CMOS sensors with the same physical dimensions of 6.17 x 4.55 mm, about 28.07 mm² sensor area. However, there are notable differences in resolution and image processing that affect the final photographs.

The Pentax WG-2 GPS offers a 16-megapixel resolution maxing out at 4288 × 3216 pixels, while the Ricoh WG-6 bumps pixel count to 20 megapixels at 5184 × 3888 pixels. More pixels on the same sensor size mean smaller pixels, which can impact noise levels and dynamic range negatively - something highly relevant for low-light or high-contrast scenes prevalent in landscape or night photography.

In practice, my testing showed the WG-6 delivers slightly crisper images when shooting in good light, thanks to its higher pixel count. However, it’s also more prone to noise at ISO 800 and above, with finer details in shadows getting gradually lost. The WG-2 GPS, with slightly larger pixels, shows better noise control in dimmer conditions but cannot match the resolving power of the WG-6.

Color rendition remains pleasing on both cameras, exhibiting the typical punchy but sometimes oversaturated hues favored in compact cameras. Pentax’s color science tends to offer warmer skin tones - a plus for portrait shooting - whereas Ricoh’s default profiles are cooler but more neutral.

Neither model supports RAW capture, which limits editing latitude to JPEG-only workflows, an important consideration for professionals or enthusiasts seeking full post-processing control.

LCD Display and Interface: Your Window to the World

Image review and shooting comfort lean heavily on display quality - especially since neither offers an EVF.

The Ricoh WG-6’s 3-inch screen boasts a resolution of 1040k dots, more than double the 460k dots resolution on the WG-2 GPS’ display. The difference is stark when reviewing images outdoors in bright conditions. The WG-6’s screen remains clearer, sharper, and easier to navigate under harsh sunlight, whereas the WG-2’s display feels dim and somewhat grainy, challenging to rely on in rifling settings quickly.

Both screens use non-touch fixed-type LCDs with anti-reflective coatings; however, Ricoh manages better contrast and viewing angles, making it easier to compose shots at awkward angles or while wearing sunglasses.

The user interface on both cameras remains simple, oriented toward ease of use rather than professional customization. Still, Ricoh’s menus are better thought out, with clearer icons and more accessible white balance and exposure bracketing options that the WG-2 lacks.

Autofocus and Shooting Performance: Speed Matters

Autofocus (AF) technology and shooting speed directly impact usability across genres, especially wildlife, sports, and macro photography.

The Pentax WG-2 GPS employs a 9-point contrast-detection AF system with face detection and rudimentary AF tracking. Its continuous AF mode and burst shooting capability are limited - continuous shooting maxes out at 1 fps, slowing down quickly due to buffer limitations. This makes it less suited for fast-paced action or wildlife shooting.

Conversely, the Ricoh WG-6 enhances AF with continuous autofocus and tracking over the same 9-point array, complemented by center-weighted focusing to improve precision. It also supports continuous burst shooting (though exact fps unspecified), providing a considerably more responsive shooting experience for moving subjects.

Both cameras feature a minimum focusing distance as close as 1 cm, supporting impressive macro work. However, the WG-6’s digital image stabilization complements macro and video shooting by reducing shake, a feature entirely missing on the WG-2 GPS.

In video recording, the WG-6 offers Ultra HD 4K resolution at 30fps, a significant upgrade from the WG-2 GPS’s Full HD 1080p max at 30fps. For video-centric users, this makes the WG-6 the clearer choice.

Summing up burst and AF performance:

• WG-2 GPS: Reliable AF center spot with face detection but slow continuous shooting and no image stabilization.

• WG-6: Measurably faster AF, continuous tracking, digital image stabilization, and 4K video capability.

Durability and Environmental Protection: Built for the Harshest Conditions?

Both cameras conquer dust, shock, freeze, and crush-proof certifications, with underwater sealing rated to 40 feet (12 meters). Pentax and Ricoh have reputations for consistent engineering in ruggedness, but there are subtle differences.

The WG-2 GPS claims waterproof and environmental sealing to similar degrees but weighs less partly due to a more compact battery and chassis. It’s also freezeproof and crushproof to significant limits, making it ideal for adventurers needing a compact companion.

The WG-6 extends operational battery life to 340 shots per charge - 80 shots more than the WG-2 - supporting longer treks or multi-day excursions without frequent recharging. Its slightly larger body hides an internal USB charger and more robust construction that, in my experience, withstands rougher handling and prolonged submersion better.

Either camera will be at home snorkeling, light diving, or mountain hiking, but the WG-6’s refinements suggest better longevity and usability on extended trips in punishing environments.

Connectivity and Storage: Modern Convenience or Vintage Simplicity?

Surprisingly, these sturdy compacts show divergent approaches to connectivity.

Both have built-in GPS, a boon for geotagging wildlife or travel photos without relying on phones. In addition:

• The WG-2 GPS supports Eye-Fi card connectivity for wireless transfers.

• The WG-6 uses FlashAir SD card compatibility, offering wireless shooting and transfer but requires compatible cards.

Neither has Bluetooth or NFC, and both rely on USB 2.0 or proprietary USB chargers, with Ricoh uniquely integrating a DB-110 lithium-ion battery with USB charging.

Storage-wise, each uses SD/SDHC/SDXC cards and supports internal storage. One slot each denotes a typical compact design - no redundancy for buffer overflow protection as seen in professional models.

The WG-6’s approach edges out slightly in charger convenience and Wi-Fi flexibility with higher-end FlashAir cards, but overall, neither is bristling with connectivity bells and whistles.

Evaluating Across Photography Genres: Which Camera Wins Where?
