Today, we compare two cameras that cater to quite different niches yet occasionally share comparable price points: the Pentax Optio WG-1, a rugged waterproof compact aimed at adventure shooters, and the Sony Alpha NEX-6, a more advanced mirrorless system camera designed for enthusiast-level versatility. Drawing on extensive hands-on testing experience of over 250 camera models, this comprehensive comparison will examine both cameras’ specifications, real-world usability, and imaging performance across key genres. Our goal: to empower you with nuanced insights for making an informed decision that fits your photographic ambitions.

First Impressions and Ergonomics: Compact Rugged Convenience Meets Rangefinder-Style Refinement

Right out of the gate, the Pentax WG-1 is strikingly compact and robust, with dimensions of 114 x 58 x 28 mm and a lightweight 157 grams. Its design prioritizes durability and portability, featuring comprehensive environmental sealing that makes it waterproof, dustproof, shockproof, crushproof, and even freezeproof. This is an all-weather tool engineered for adventure photographers who want to document action in challenging conditions without worrying about camera damage. The fixed lens eliminates complications of lens changes and offers a reassuringly simplified user interface.

In contrast, the Sony NEX-6 is a more substantial package at 120 x 67 x 43 mm and 345 grams, sporting a classic rangefinder-style mirrorless chassis that prioritizes ergonomic grip and manual control accessibility. Its design includes a large electronic viewfinder with 2359k-dot resolution offering 100% frame coverage and a 3-inch tilting 921k-dot LCD screen for flexible composition. While it lacks environmental sealing, the NEX-6 offers superior handling and direct access to exposure modes, ideal for enthusiasts and semi-pro use.

The ergonomic contrast essentially boils down to Pentax’s rugged pocketability versus Sony’s more conventional but sophisticated command layout.

User Interface and Controls: Simplified Toughness Meets Creative Control

The WG-1’s minimalist control scheme is, by design, straightforward. It lacks manual exposure modes, focusing instead on point-and-shoot ease with a single shutter button, zoom lever, and limited menu navigation. There is no aperture or shutter priority; no exposure compensation. The small 2.7-inch fixed TFT LCD with only 230k dots is underwhelming by modern standards, and the absence of a viewfinder requires composing via its screen in bright conditions, which can be challenging despite an anti-reflective coating.

In contrast, the NEX-6 is packed with physical dials and buttons that provide rapid changes to shutter speed, aperture, ISO, exposure compensation, and autofocus settings. The inclusion of an electronic viewfinder (EVF) and a tilting Xtra Fine LCD screen (900+k dots) significantly enhances framing versatility. Exposure modes include manual, aperture priority, shutter priority, and program, giving the user full creative freedom.

While the WG-1 excels in simplicity and rugged operability, the NEX-6 offers the sophisticated controls expected from mid-range mirrorless photography, demonstrating a clear divide in intended use cases.

Imaging Technology: Sensor Size and Resolution Drive Quality Differences

One of the largest disparities between these two cameras lies in their sensor design and resultant image quality potential. The Pentax WG-1 employs a 1/2.3-inch CCD sensor measuring just 6.17 x 4.55 mm with a modest 14-megapixel resolution. It features an optical low-pass (anti-aliasing) filter, which smooths details to avoid moiré but sacrifices some sharpness. CCD technology, once dominant in compact cameras, tends to be noisier at higher ISO compared to modern CMOS sensors, especially beyond ISO 400. The sensor's small size and lower dynamic range pose inherent challenges for image quality, especially in low-light or high contrast scenarios.

Conversely, the Sony NEX-6 boasts a much larger APS-C type CMOS sensor measuring 23.5 x 15.6 mm, delivering 16 megapixels. This sensor area (366.6 mm²) is approximately 13x larger than the WG-1's sensor, allowing for significantly improved light-gathering capability, dynamic range, and noise control. The NEX-6 sensor includes a Bayer filter and a high degree of color depth, supported by Sony’s proprietary Bionz image processor, which together confer solid low-light capability (ISO up to 25600) and excellent tonal gradation. It also supports shooting in RAW, enabling extensive post-processing flexibility.

In direct testing, the NEX-6 cleanly outperforms the WG-1 in image sharpness, color fidelity, and noise handling, especially at ISO 800 and above. For photographers prioritizing image quality - particularly for landscape, portrait, or professional use - the larger sensor grants a decisive advantage.

Autofocus and Shooting Speed: Still and Action Photography Considerations

The autofocus systems on these cameras reflect their divergent targets. The Pentax WG-1 uses a contrast-detection AF system with 9 focus points. While it supports single AF, it lacks continuous autofocus and sophisticated tracking systems. Autofocus is generally slower and less reliable in low light or with moving subjects. Burst shooting capability is limited to a sluggish 1 frame per second, insufficient for fast action sequences.

The Sony NEX-6 employs an advanced hybrid AF system combining phase-detection and contrast-detection autofocus across 99 focus points. It supports continuous AF (AF-C) allowing for smooth focus tracking on moving subjects - a boon for wildlife and sports photography. The maximum burst frame rate is an impressive 10 frames per second, enabling rapid series capture without buffer delays. Face and eye detection AF are integrated, increasing precision for portraiture.

In real-world shooting tests, the NEX-6 reliably locked focus quickly and accurately, adapting well from street environments to wildlife scenarios. The WG-1’s AF performance is best suited to static subjects in good lighting conditions.

Build Quality and Environmental Sealing: Ready for Adventure vs Studio/Urban Use

A standout feature of the Pentax WG-1 is its extensive environmental durability. The camera is fully waterproof (rated to 10m depth), dustproof, shockproof (drops up to 1.5 m), crushproof (up to 100 kgf), and freezeproof (operating down to -10°C). This rugged build offers peace of mind when photographing in extreme environments such as underwater, mountain expeditions, or dusty deserts. Its compact size combined with this durability stands out in the waterproof compact camera niche.

The Sony NEX-6, while robustly built with a magnesium alloy body, is not environmental sealed or waterproof. It is vulnerable to dust and moisture ingress, requiring more care in adverse conditions or the use of protective housings. This camera is better suited for controlled environments, street photography, or travel where weather risks are lower or manageable.

Photographers whose primary need is adventure or underwater shooting will find the WG-1 uniquely tailored to their requirements.

Display and Viewfinding: Composition Flexibility and Image Review

The WG-1’s 2.7-inch TFT LCD is fixed and lower resolution, which can complicate composing images in bright sunlight despite its anti-reflective coating. Without any viewfinder, the camera relies solely on the LCD for framing, which may be a limitation for some users.

By contrast, the NEX-6’s rear 3-inch LCD panel can tilt up 90° and down 45°, greatly aiding shooting from high or low angles, and boasts a high pixel count that sharply renders focus peaking, live histogram, and other shooting aids. Furthermore, the electronic viewfinder (EVF) delivers a bright, eye-level composition experience, invaluable for outdoor shoots in bright light or when wanting a close-up viewfinder experience akin to DSLRs.

For applied photographers, this translates to greater creative control and compositional precision with the Sony.
