• Sony A330’s APS-C sensor is over 13 times larger in area than the WG-4’s tiny 1/2.3" sensor. Bigger sensors generally offer superior image quality, especially noticeable in low-light performance, dynamic range, and color depth.
• The CCD sensor technology in the A330, while older, traditionally produces pleasing color rendition and controlled noise at lower ISOs. However, it is less effective at high ISO compared to modern CMOS sensors.
• WG-4’s BSI CMOS sensor improves sensitivity and noise performance slightly above typical compact cameras but cannot compete with the large sensor DSLR.
• The WG-4’s 16 MP resolution surpasses the A330’s 10 MP, which can benefit cropping flexibility in casual use, but image quality and especially noise handling hinge heavily on sensor size.
• Absence of raw support in WG-4 restricts post-processing flexibility - a major factor for professionals.

Real-world testing confirmed: The Sony A330 produces cleaner images with better depth and detail in varied lighting conditions, while the WG-4’s photos tend to show more noise and reduced dynamic range, particularly in shadows and highlights. However, outdoors under ample light, the WG-4 delivers respectable RAW-quality JPEGs suitable for casual photography and adventure documentation.

Autofocus and Performance: Accuracy under Pressure

Autofocus (AF) speed and accuracy are mission-critical for capturing fleeting moments, especially in sports, wildlife, and portraiture.

Autofocus Systems

How They Perform in the Field?

• The WG-4 uses contrast-detection autofocus, typical for compact rugged cameras. I found it reliable in good lighting but slower to lock focus, especially for moving subjects.
• The Sony A330’s hybrid AF system leverages phase detection for faster and more accurate focus acquisition, notably during continuous focus tracking in daylight.
• While the A330 lacks advanced tracking like animal eye detection or sophisticated AF area selection, its AF center and multi-area modes perform well for still subjects and moderate action.
• The WG-4 does support face detection but no eye detection - a limitation if you want precise focusing in portraiture.
• Continuous shooting speeds are slow on both cameras: 2 FPS on WG-4 and 3 FPS on A330 - not suitable for rapid sports or wildlife action, but fine for casual bursts.
