The Four Thirds sensor’s substantially larger photosites underpin superior noise performance, dynamic range, and color fidelity.

Image Processing

Featuring Olympus’s TruePic VII image processor, the E-PL7 benefits from advanced noise reduction algorithms and improved color reproduction, particularly in subtle skin tones and high dynamic range scenes. The SZ8’s Venus Engine processor, while competent for its class, cannot match these refinements, resulting in comparatively flatter images and more noise in low light conditions.

Color Depth and Dynamic Range

Based on DXO Mark data, the E-PL7 achieves a color depth of 22.7 EV and dynamic range of 12.4 stops, both respectable for its sensor class. The SZ8 has not been DXO-tested but historically, 1/2.3” CCD compacts rarely exceed 11 stops dynamic range and exhibit lower color depths by design constraints.

High ISO Performance

The maximum native ISO for the E-PL7 is ISO 25600, though usable image quality declines beyond ISO 1600-3200. For comparison, the SZ8 tops out at ISO 1600 natively, with extended ISO up to 6400, where image degradation is severe due to sensor noise and limited processing.

Autofocus Systems: Speed, Accuracy, and Tracking Fidelity

Contrast-Detection AF vs Phase-Detection Hybrid

The E-PL7 is equipped with an 81-point contrast-detection autofocus system, featuring face detection, touch-to-focus on the rear LCD, and eye detection capabilities. It supports continuous autofocus and tracking modes, improving action and portrait reliability.

By contrast, the SZ8 has a rudimentary 9-point contrast-detection AF system without face or eye detection and lacks continuous tracking, underscoring its suitability for static subjects and casual shooting.

In real-world testing, the E-PL7 consistently locks focus faster in varied lighting and maintains focus on subjects with more confidence, especially in rapidly changing scenes such as street or sports photography.

Articulated LCD and Viewfinder Options: User Interface Considerations

Rear LCD Screens

Both cameras feature 3-inch LCDs, yet the E-PL7 boasts around 1,037k-dot resolution and a fully tilting touchscreen supporting touch AF and intuitive menu navigation.

The SZ8 provides a fixed 460k-dot TFT LCD without touchscreen capabilities, limiting composition flexibility and direct control ease.

Viewfinders

Neither camera includes a built-in viewfinder; however, the E-PL7 accepts an optional external electronic viewfinder (EVF) - a notable advantage for photographers who prefer eye-level framing in bright environments or demanding shooting conditions.

The SZ8 omits any viewfinder compatibility, relying solely on the LCD for image preview, which can cause visibility issues under direct sunlight.
