Sensor Technology and Image Quality

Sensor performance is the cornerstone of any camera’s imaging prowess, driving resolution, dynamic range, and low-light capabilities. Both cameras utilize the Micro Four Thirds sensor format (17.3 x 13 mm sensor size), but they differ considerably in resolution and in-sensor technology.

The E-PL8 is equipped with a 16-megapixel CMOS sensor paired with Olympus’s TruePic VII image processor. While this combo delivers respectable image quality for entry-level photographers, especially in daylight and well-lit conditions, it reaches its limits in challenging lighting scenarios. Noise becomes pronounced above ISO 1600, and dynamic range is moderate - neither providing the flexibility that advanced photographers might seek for landscape or professional portrait work.

The Panasonic GH5, meanwhile, boasts a 20.3-megapixel CMOS sensor devoid of an anti-aliasing filter, paired with the powerful Venus Engine processor. This translates to a higher resolution output (up to 5184 x 3888 pixels) with crisper detail reproduction and enhanced edge sharpness - particularly evident in landscape and macro photography where texture fidelity is paramount. Measured DxO Mark scores for the GH5 align with these observations, showing strong overall performance (77 points), impressive color depth (23.9 bits), a broad dynamic range (13 stops), and excellent high-ISO performance (ISO 807). Its native ISO range peaks at 25600, with clean noise characteristics maintained up to ISO 3200 to 6400 in real shooting.

In practice, we found the GH5 provides more latitude for post-processing and cropping without noticeable degradation, whereas the E-PL8 pushing beyond its native ISO range displays earlier noise artifacts and reduced detail.

Autofocus Systems: Speed, Accuracy, and Practical Use

Autofocus (AF) performance is critical across fast-moving photography disciplines such as sports and wildlife, as well as for spontaneous street captures where decisive focus pinpoints image sharpness.

The Olympus E-PL8 employs a contrast-detection AF system with 81 focus points spread across the frame. While this setup supports face detection, touch-based AF point selection, and basic continuous tracking, the system’s speed and tracking reliability remain modest. Testing showed some lag when trying to track fast subjects and occasional hunting in low contrast areas. Its eye-detection AF is competent but not industry-leading, often requiring manual refinement to achieve sharp focus on eyes during portraits.

By contrast, the Panasonic GH5 integrates an advanced contrast-detection system with a substantially larger 225-point AF array, incorporating Depth-from-Defocus technology to improve accuracy. The camera delivers a seamless AF experience, boasting quick locking and impressive tracking precision with complex subjects, reinforced by continuous AF modes that sustain focus through erratic movements. Although lacking phase-detection pixels, the hybrid contrast-based system used in the GH5 compensates with improved algorithms and more AF points.

These advantages manifest in our controlled autofocus tests - the GH5 achieves continuous burst shots at 12 fps with consistent AF tracking, a notable upgrade over the E-PL8's 8 fps performance with intermittent autofocus assurance.
