Summary: If you plan rugged or outdoor-focused photography, the Pentax WG-3 GPS offers unparalleled resilience and grip. For discrete travel or street shooting where compactness is paramount, the Sony W350’s lightweight design shines.

Sensor and Image Quality: The Heart of the Matter

At the core of any camera is its sensor. Both cameras feature 1/2.3” sensors, a common size in compact cameras, but there are vital differences in sensor technology and resolution that impact image quality significantly.

• Pentax WG-3 GPS: Utilizes a 16MP BSI-CMOS sensor with an anti-aliasing filter, enabling improved low-light sensitivity and higher max ISO (up to 6400). BSI (backside illuminated) sensors are known to gather more light efficiently, reducing noise.
• Sony W350: Employs a 14MP CCD sensor, also with anti-aliasing. CCD sensors typically yield excellent color rendition and detail but struggle somewhat in low-light and high ISO scenarios compared to CMOS counterparts.

Real-World Image Quality

In my controlled indoor and outdoor tests, WG-3 GPS’s sensor presents cleaner images with better dynamic range, especially in shadows and highlights. The increased ISO range lets you shoot in darker environments with less noise degradation than the W350.

The Sony’s CCD offers pleasing color accuracy in daylight and moderate ISO but visibly introduces noise and detail loss beyond ISO 400. Its top shutter speed of 1/1600s limits freezing fast movement compared to the WG-3 GPS’s 1/4000s capability.

Overall resolution advantages are slight; WG-3 GPS produces 4608x3456px images vs. W350’s 4320x3240px, but the former’s improved sensor design portends better clarity and cleaner shadows.

Summary: For crisp, cleaner images and better low-light flexibility, the Pentax WG-3 GPS sensor outperforms the Sony W350’s older CCD sensor.

Lens and Focusing: Versatility Meets Speed

Lens Specifications and Optical Performance

• Pentax WG-3 GPS: 25-100mm equivalent zoom (4x), aperture f/2.0-4.9
• Sony W350: 26-105mm equivalent zoom, aperture f/2.7-5.7

The WG-3 GPS’s faster f/2.0 aperture at the wide end is a significant plus for low-light shooting and shallow depth-of-field effects, especially in portraits and macro. The Sony’s slightly longer zoom range offers additional framing flexibility but with a slower aperture, reducing low-light performance and bokeh capability.

Macro Capabilities

Pentax’s macro focusing range down to 1cm (≈0.4 inches) is outstanding, allowing true close-up shots with excellent detail - very useful for nature photographers and macro enthusiasts. The Sony only focuses to 10cm minimum, limiting its macro appeal.

Autofocus Performance

The WG-3 GPS’s 9 contrast-detection AF points with face detection deliver fast, reliable focus, even under challenging lighting or subject movement scenarios. It also supports AF tracking, helpful for moving subjects. Sony’s 9 AF points and contrast detection are good but lack face detection, and autofocus can be slower, especially for continuous focus modes.

Summary: For versatility, faster apertures, and superior macro ability, the Pentax WG-3 GPS takes the lead. Sony W350 remains adequate for stable, well-lit subjects but won’t match the WG-3 GPS’s speed or close-focusing precision.
