Sensor Technology and Image Quality: One Size Does Not Fit All

At the heart of photographic quality lies the sensor. The Olympus FE-5020 employs a traditional CCD sensor sized at 1/2.3 inches (6.17x4.55 mm) with approximately 12 megapixels. CCD sensors from this era often lag in high ISO noise performance and dynamic range. Additionally, the sensor area is a modest 28.07 mm², significantly limiting light-gathering ability.

In contrast, the Sony RX100 IV is equipped with a large 1-inch BSI-CMOS sensor measuring 13.2 x 8.8 mm (116.16 mm²), nearly four times larger in surface area. With 20 megapixels, this sensor benefits from back-side illumination technology, enhancing quantum efficiency, low-light performance, and dynamic range.

Sensor size comparison and resultant image quality impact

Key Image Quality Parameters:

Image Quality Insights:

• Olympus FE-5020 is constrained by its sensor size and age, delivering adequate images under ample daylight but showing early onset noise and aggressive noise reduction artifacts above ISO 400. Color fidelity is basic, and absence of RAW support limits post-processing flexibility.
• Sony RX100 IV excels with high resolution and wide dynamic range, enabling detailed images with rich color gradation and clean low light results up to ISO 3200 and beyond. RAW file support unlocks professional-grade editing potential.

Autofocus and Performance: Precision Versus Simplicity

Autofocus (AF) performance markedly distinguishes entry compacts from enthusiast-level models.

• The Olympus FE-5020 relies exclusively on contrast-detection AF with a single central focusing area. It lacks face or eye detection, continuous AF, or autofocus tracking features, which means focus accuracy depends heavily on good contrast and stationary subjects.
• Contrastingly, the Sony RX100 IV sports a hybrid AF system with 25 contrast-detection points and advanced subject tracking capabilities, including face detection. It supports continuous AF, AF-C mode for moving subjects, and selective focus point assignment, ideal for dynamic photography like sports or wildlife.

In real-world testing, the FE-5020’s AF is significantly slower and more prone to hunting, making it suitable essentially for still subjects and casual snapshots. RX100 IV achieves consistent, snappy focus lock even in low light or fast action scenarios, which is vital for professional or enthusiast use.

Handling and User Interface: Intuitive Usage or Creative Control?

The Olympus FE-5020 features a basic, menu-driven interface displayed on a fixed 2.7-inch low-resolution LCD. It lacks a touchscreen, no viewfinder, and provides only automatic shooting modes. Exposure compensation, manual aperture, or shutter control options are absent, severely limiting photographers wishing to influence image outcomes.
