Exploring the Pentax WG-2 GPS vs Sony NEX-6: A Real-World Camera Showdown

When stepping into the world of digital cameras, the landscape often feels dense with choices, each promising something unique or specialized. Today, I’m pulling two quite distinct cameras into the spotlight: the rugged Pentax Optio WG-2 GPS, a compact tough camera aimed at adventurers, and the sophisticated Sony Alpha NEX-6, a mirrorless system body designed for advanced amateurs and professionals seeking flexibility and performance. Curveball: they come from different eras and categories, yet both have earned their fans.

Having tested thousands of cameras over 15 years, I’ve developed a methodology that balances technical benchmarks with real-world shooting scenarios. In this in-depth comparison, I’ll dissect these two models across all major photography disciplines, user experience, and technical specifications, serving photographers of varied preferences. Let’s dive in.

Making Sense of the Physical Footprint: Size, Ergonomics and Design

First impressions matter. The way a camera feels in your hands largely determines your shooting comfort and freedom.

The Pentax WG-2 GPS is a tough, compact, and utilitarian powerhouse measuring just 122 x 61 x 30 mm and weighing a mere 198 grams with battery. The design philosophy here is clear: portability and ruggedness. Its sealed body lives up to claims of waterproof (up to 40 ft), freezeproof (down to 14°F), shockproof, crushproof, and dustproof durability. With a slightly blocky but grippy chassis and rubberized overmold bits, it’s reassuringly solid in rough terrain or adverse weather.

By contrast, the Sony NEX-6 is a rangefinder-style mirrorless camera measuring 120 x 67 x 43 mm and tipping the scales at about 345g - a size and weight increase reflecting its more complex hardware. The magnesium alloy body is sleek but demands some getting used to, especially compared to the simpler Pentax. It lacks environmental sealing, which cues you to treat it more like a studio or travel companion than a rugged field device.

Looking from above, the Sony’s control layout offers more direct access to exposure settings, featuring dedicated dials and buttons, useful for shooters used to DSLRs, while the WG-2’s controls are minimal, designed more for ease of use under physically challenging conditions.

In the hand, the WG-2 invites quick point-and-shoot adventures without fuss, while the NEX-6 offers a more deliberate shooting experience - perfect for those who want to tweak settings on the fly.

Sensor and Image Quality: The Heartbeat of Each Camera

Image quality boils down largely to sensor technology, size, and processing. Here the gulf between a compact waterproof and a mirrorless camera is particularly stark.

The WG-2 GPS's 1/2.3" BSI-CMOS sensor measures approximately 6.17 x 4.55 mm with a surface area of 28.07 mm², packing 16 megapixels. While respectable for a compact tough camera of its era, the sensor’s physical size limits dynamic range and low-light capabilities. The maximum ISO tops out at 6400 but with expected noise. Meanwhile, the fixed lens spans 28-140 mm equivalent with a modest aperture from f/3.5 to f/5.5. No raw format support here, which reduces post-processing flexibility.

Flipping to the NEX-6, its APS-C 23.5 x 15.6 mm sensor (366.6 mm² area), also 16 MP, is over 13 times larger by sensor area - an immediate advantage for image quality, detail retention, and noise control. Native ISO range swells to an impressive 100-25600 range, backed by Sony’s Bionz processor optimized for clean output and rich color depth. Crucially, the NEX-6 shoots raw files, giving photographers significant latitude in editing workflows.

From my testing, the NEX-6 consistently delivers images with superior dynamic range – recovering shadows and highlights in challenging lighting – and better color depth, harnessing the sensor size advantage. The WG-2 tends to produce acceptable images only under good lighting, with noise creeping into shadows and less detail rendering at higher ISO.

Seeing the Frame: Viewfinders and LCD Experience

In-the-moment visibility is critical across shoot genres, especially when bright conditions or spontaneous composition come into play.

The WG-2 GPS relies on a 3-inch fixed, widescreen TFT LCD with 460k dots. Its anti-reflective coating helps usability outdoors but the somewhat low resolution and fixed angle can frustrate creativity in unusual shooting postures, many of which adventure photographers crave.

The Sony NEX-6 ups the ante with a 3-inch tilting Xtra Fine LCD boasting 921k dots - double the resolution. This means a sharper, more detailed preview, enabling more accurate focus checks. The tilt mechanism provides versatility for low-angle or overhead shots.

Adding value, the NEX-6 features a bright electronic viewfinder (EVF) with 2.36 million dots and 100% coverage, magnification of 0.73x - a significant aid in composition, focus, and exposure preview. The WG-2 GPS does not offer a viewfinder, which can result in challenges under direct sunlight or fast-paced scenarios.

Autofocus and Speed: Catching the Moment

Autofocus (AF) performance influences nearly every type of photography - from decisive safari shots to fleeting street portraits.

The WG-2 GPS uses contrast-detection AF with 9 focus points supplemented by face detection. It lacks continuous AF, burst shooting tops off at a leisurely 1 FPS, and there’s no phase-detection AF to boost tracking speed or accuracy. The rugged design comes at the cost of speed and sophistication. You can’t expect explosive tracking of fast wildlife or sports action. However, the camera’s face detection is competent for casual portraits in bright light.

The Sony NEX-6 features a hybrid AF system combining contrast and phase detection, boasting 99 focus points. This allows for much quicker and more precise autofocus performance, including autofocus tracking and continuous AF during burst sequences at up to 10 FPS. Real-life tests affirmed this system’s power in wildlife, sports, and even street photography - staying locked on moving subjects effectively.

While both cameras support face detection, the NEX-6 also offers selective AF point selection, providing better control especially in complex scenes. The NEX-6’s focus system feels much more responsive and professional-grade.

Zoom and Lenses: Fixed Versus Interchangeable

There is an undeniable flexibility and creative freedom difference between a fixed-lens camera and one with interchangeable lenses.

Pentax’s WG-2 GPS comes with a 5x zoom, equivalent to 28-140 mm at relatively slow apertures (f/3.5-5.5). Its standout feature lies in its excellent macro mode focusing as close as 1 cm, an asset for close-up natural detail, beneficial in travel or casual macro shooting.

Conversely, the Sony NEX-6 taps into the robust Sony E-mount system, with over 120 native lenses ranging from ultra-wide primes to super-telephoto zooms and excellent macro lenses. This lens ecosystem is a boon for professional and enthusiast photographers who want to tailor their setup.

The focal length multiplier of 1.5 also improves telephoto reach with APS-C lenses, favoring wildlife and sports shooters.

Durability and Environmental Suitability

If you’re choosing a camera for arduous environments or travel where conditions are unpredictable, build quality and protections are make-or-break.

The WG-2 GPS is explicitly built for adventure photographers and fieldworkers. Its waterproof, freezeproof, shockproof, dustproof, and crushproof body stands out even years after launch. You can dunk it in water or drop it without immediate worry.

The Sony NEX-6, while solidly built, is not ruggedized and purposely avoids sealing to keep weight down. It’s suited for controlled conditions or gentle travel adventures with care.

Battery Life and Storage Media

Handling power management big-picture is often overlooked but crucial, especially if traveling or shooting in remote locations.

WG-2 GPS uses a proprietary D-LI92 battery rated around 260 shots per charge, which isn’t exceptional but is competitive for compacts of its class and size.

By contrast, the NEX-6’s relatively efficient NPFW50 battery delivers up to 360 shots per charge, a distinct advantage for long sessions or event photography. Both cameras utilize SD cards, but NEX-6 expands compatibility to Sony’s Memory Stick formats as well.

Video Capabilities: What Moves These Cameras Can Make

Videographers have notably higher expectations today, and cameras need to respond with decent specs.

The Pentax WG-2 GPS offers Full HD 1080p at 30 FPS, plus HD 720p at 60 FPS, encoded in MPEG-4 and H.264. Its fixed lens and lack of image stabilization limit smoothness, but it captures solid casual footage in bright conditions. There's no external mic input, which restricts audio control.

The Sony NEX-6 improves with Full HD 1080p at 60 and 24 FPS, also providing 1440x1080 recording and AVCHD/MPEG-4 encoding. Though it lacks in-body stabilization, many lenses offer OSS (Optical SteadyShot). Again, no mic input is a downside for serious filmmakers, although the image quality and autofocus during video shooting stand ahead.
