Personally, I admire Pentax’s tactile approach for outdoor shooting, while the Sony’s minimalism is appealing for casual travel and street photographers seeking unobtrusive gear with a long zoom.

Sensor Technology and Image Quality: Same Size, Different Results

Both cameras share a 1/2.3" BSI-CMOS sensor measuring 6.17 x 4.55 mm - typical for compacts - but there are key distinctions in resolution and sensitivity.

The landscape here is classic trade-off territory: the Sony WX350 offers 18 MP resolution versus 16 MP on the WG-2 GPS, with Sony pushing the maximum native ISO range up to 12,800 compared to Pentax's ISO ceiling of 6,400. This gives Sony an edge in resolving detail and capturing usable images in low light.

Despite similar sensor sizes, Sony’s image processing engine delivers noticeably cleaner high ISO images with less noise - a vital advantage in dim interiors, evening street scenes, and even astro shoots. By contrast, Pentax’s older processor and lower ISO range reflect the WG-2's design era and emphasis on durability over cutting-edge sensitivity.

However, shooting raw files isn’t possible with either camera, which somewhat limits post-processing flexibility for professionals accustomed to fine-tuning files, especially in portrait or landscape work.

In practical field testing, the WG-2 GPS yields pleasing daylight images with respectable color fidelity and contrast - ideal for underwater or snowy conditions where weather sealing matters most. Meanwhile, Sony’s WX350 excels at capturing crisp, vibrant shots with slightly better dynamic range thanks to more refined noise handling and processing algorithms.

Viewing and Interaction: LCD and Interface Experience

Since neither model features electronic viewfinders, reliance falls squarely on their LCD displays - a crucial interface for composing shots.

Both employ 3-inch fixed TFT LCDs with anti-reflective coating and equal resolution (460k dots). The Pentax WG-2 GPS’s screen excels outdoors, retaining reasonable visibility in direct sunlight due to its matte finish and anti-glare surface. Sony’s WX350 uses a glossy finish that delivers more contrast indoors but can struggle under bright daylight.

Neither offers touchscreen control, limiting direct interaction; navigation rests on physical buttons alone. Sony's menu system is straightforward but somewhat dated, while Pentax organizes its options clearly with large, legible icons optimized for quick setting changes when wearing gloves.

Your choice here boils down to environment: the WG-2’s screen is simply more practical for harsh, bright, or wet conditions, whereas the Sony shines in typical indoor or street shooting scenarios.
