Pentax WG-3 GPS vs Sony RX10 II: A Deep Dive into Two Unique Cameras for Distinct Photographic Journeys

Choosing your next camera can feel daunting - plenty of options, each promising great results. The Pentax WG-3 GPS and Sony RX10 II come from very different design schools and target use cases, but both offer compelling features. Drawing on our comprehensive hands-on testing of thousands of cameras over 15 years, this comparison distills how each performs across key photography and video disciplines, so you can confidently select the model that aligns with your creative ambitions.

At a Glance: Design, Size, and Build

The compact and rugged Pentax WG-3 GPS (left) contrasts with the larger, SLR-style Sony RX10 II (right). Size influences portability and handling comfort.

• Pentax WG-3 GPS: Ultra-compact, lightweight (238g), and designed for adventure. It features a tough environmental sealing that is waterproof (up to 14m), dustproof, shockproof, crushproof, and freezeproof. The body measures 125×64×33 mm, fitting easily in a pocket or small bag.
• Sony RX10 II: Larger bridge camera weighing 813g with dimensions of 129×88×102 mm. Built with weather sealing but lacks full waterproofing or freezeproofing. Its ergonomics resemble a DSLR with a pronounced grip and robust control layout.

For travel and outdoor adventuring, the Pentax excels on portability and durability. Meanwhile, the RX10 II offers superior handling for extended shoots, especially when paired with a neck strap.

Control Ergonomics and Interface: Handling Everyday Operations

Top panel comparison reveals Sony’s abundance of dedicated dials vs. Pentax WG-3 GPS’s simplified button layout.

• WG-3 GPS: Simplified top controls with basic buttons, suitable for quick, straightforward operation. No exposure or aperture priority modes - made with a rugged point-and-shoot philosophy. The 3-inch fixed TFT LCD (460k dots) is clear but not touch sensitive.
• RX10 II: Rich physical controls including mode dial with shutter/aperture priority, custom function buttons, and a top display panel. A tiltable 3-inch screen (1.2 million dots) facilitates live view in tricky angles. The electronic viewfinder (2.4M dots) with 100% coverage is a standout for composing in bright light.

Overall, if you prize full manual control and tactile feedback, the RX10 II is a clear winner. The WG-3 GPS favors simplicity and rugged reliability over operational flexibility.

Sensor Size and Image Quality Fundamentals

The Sony RX10 II’s 1” sensor eclipses the Pentax’s smaller 1/2.3” sensor in surface area by over 4x, which directly impacts image quality.

The RX10 II’s larger sensor grants better noise control at high ISO, richer dynamic range, and improved color depth. The RX10’s RAW capability affords vast post-processing flexibility, essential for professional workflows.

In contrast, the WG-3 GPS’s compact sensor influences image quality - noise becomes prominent beyond ISO 800, and dynamic range is constrained. However, it suits casual use and specialized scenarios needing utmost durability more than technical image excellence.

Display and Viewfinder: Shooting Feedback and Framing

Sony’s high-resolution tiltable display and electronic viewfinder offer compositional confidence unmatched by Pentax’s fixed, lower-res screen and no viewfinder.

• Pentax WG-3 GPS: 3-inch fixed LCD with anti-reflective coating is decent in daylight but can struggle under harsh sunlight. No viewfinder option.
• Sony RX10 II: 3-inch tilting LCD (1.23M dots) and a bright electronic viewfinder (2.36M dots) with 0.7x magnification. The EVF offers 100% coverage with eye sensor for automatic switching, critical for precision framing across all lighting conditions.

For extensive outdoor shooting, especially in bright or challenging light, the RX10 II’s advanced viewing setup is a clear advantage.

Autofocus and Shooting Performance: Tracking, Speed, and Precision

The RX10 II shines with sharp, fast autofocus capable of 14 fps burst shooting and tracking moving subjects - ideal for sports, wildlife, and dynamic events. The WG-3 GPS has more basic AF performance geared toward static subjects with limited continuous shooting.

Face detection on both aids portraits, but the RX10 II’s more sophisticated algorithms and more AF points ensure faster, accurate focusing even in challenging light.

Lens and Zoom Flexibility

The RX10 II’s longer zoom range with constant wide f/2.8 aperture provides striking versatility from wide landscapes to telephoto portraits and wildlife shots, maintaining great background separation and bokeh quality. Its optical stabilization effectively curbs shake, especially helpful at telephoto reach.

The WG-3 GPS’s bright f/2 lens on the wide end and macro focus down to 1 cm make it superb for close-up nature and underwater shots but at the expense of reach and aperture consistency.

Real-World Photography Applications

Portrait Photography

• WG-3 GPS: Moderate background blur achievable at 100mm but limited by mid-range max aperture and small sensor. Face detection autofocus assists casual portraits; however, lack of RAW limits post-editing skin tone refinement.
• RX10 II: Larger sensor and fast lens produce creamy bokeh and detailed skin tones. Autofocus with face detection excels at eye tracking, giving you sharp portraits even in lower light.

Landscape Photography

• WG-3 GPS: Waterproof ruggedness wins for adventurous landscapes in extreme conditions. Limited dynamic range and sensor resolution restrict fine detail capture and highlight recovery post processing.
• RX10 II: Excellent dynamic range and resolution reveal stunning landscape textures. Weather sealing permits shooting in rain or dusty environments.

Wildlife Photography

• WG-3 GPS: Limited telephoto zoom (100mm) and slow AF make wildlife shooting challenging. Durability may appeal if you’re extremely active outdoors but expect compromised reach.
• RX10 II: Fast, precise autofocus and 200mm reach (optical zoom) enables capturing animals in motion. Burst mode helps freeze fast action with high sharpness.

Sports Photography

• WG-3 GPS: No burst shooting, slow AF and shutter speed cap limit suitability.
• RX10 II: 14 fps burst with fast AF and full manual controls give impressive sports capture flexibility. Its electronic shutter enables silent shooting during events.

Street Photography

• WG-3 GPS: Small size and quiet operation aid discretion. Fixed screen reduces risk of mechanical failure.
• RX10 II: Larger and heavier, less discrete but better image quality and control compensate for serious street photographers.

Macro Photography

• WG-3 GPS: Excellent close focus to 1cm with bright aperture for detailed macro shots. Sensor limitations reduce ultimate image quality but physical closeness is a strength.
• RX10 II: Close focus to 3cm, high resolution, and image stabilization enable sharp detail and color precision.

Night and Astro Photography

• WG-3 GPS: High ISO noise and limited manual modes restrict night use.
• RX10 II: Large sensor, high ISO (25600 boost), and full manual exposure support make it a solid choice for night and astro photography buffs.

Video Capabilities

Sony RX10 II is a clear leader here with professional-level 4K capture, microphone and headphone jacks, and high-frame-rate slow motion for creative effects. The WG-3 GPS covers basic Full HD video but lacks professional audio or stabilization features.

Battery Life and Storage

The RX10 II provides nearly double the battery stamina for longer shooting sessions. Its multi-format storage support adds flexibility for diverse workflows.

Connectivity and Extras

• WG-3 GPS: Built-in GPS for geotagging your adventure shots and Eye-Fi card support for wireless transfer.
• RX10 II: Built-in Wi-Fi and NFC for faster sharing and remote control, but no GPS.
