Sensor and Image Quality: Resolving Power and Dynamic Latitude

Both cameras utilize 16MP Micro Four Thirds sensors - a 17.3x13mm format with identical dimensions and pixel sizes, thus sharing a foundation for image characteristics such as noise performance and depth of field.

The Olympus E-M5 II employs a MOS sensor coupled with the TruePic VII image processor. This combination delivers a DxOMark sensor overall score of 73 points, highlighting respectable performance in color depth (23 bits), dynamic range (12.4 EV), and low-light ISO capability (ISO 896 at the DxOMark standard).

By comparison, the Panasonic GF8 features a CMOS sensor with the Venus Engine processor. It remains untested by DxOMark, but field reports and sample images indicate image quality broadly parallels the E-M5 II’s baseline, albeit with less robust noise control and dynamic latitude at higher ISOs.

A key differentiator is the E-M5 II’s built-in 5-axis sensor-shift stabilization, which enhances sharpness handheld and can improve image quality indirectly by allowing lower ISO or slower shutter speeds. The GF8 lacks any form of in-body image stabilization, relying entirely on lens stabilization where available.

Practical insight: The dynamic range advantage of the E-M5 II manifests in retaining highlight and shadow detail critical for landscape and portrait work. The GF8’s marginally weaker tonal latitude constrains post-processing flexibility, particularly in challenging lighting.

Autofocus Capabilities: Speed, Coverage, and Accuracy

Autofocus (AF) performance is paramount across action, wildlife, and street photography. Olympus equips the E-M5 II with a hybrid contrast-based AF system with 81 focus points, enhanced by face detection, touch-to-focus interface, and continuous tracking modes. It lacks phase-detection pixels on the sensor but compensates with sophisticated contrast detection algorithms and multiple AF area configurations.

The Panasonic GF8 uses a contrast-detection AF system featuring 23 focus points and similar face detection but with a simpler AF tracking capability.

The higher number of AF points and increased algorithmic complexity in the Olympus system translate to notably faster, more reliable autofocus acquisition and tracking, particularly in low contrast and variable lighting. The E-M5 II’s AF is capable of continuous subject tracking with 10fps burst shooting, which pairs well for wildlife and sports action.

The GF8’s AF, while responsive under good conditions, exhibits slower focus motors and less effective tracking, limiting precision in dynamic scenarios. Its maximum continuous shooting rate is 5.8fps, substantially lower than the E-M5 II.

Display and Viewfinder Utility: Composition and Review

Both cameras feature 3-inch LCD screens with approximately 1 million dots resolution, supporting touch input for focus and menu navigation. The Olympus has a fully articulated display, enabling waist-level, over-the-head, and front-facing angles - a boon for macro, video, and vlogging applications.

The Panasonic GF8’s screen tilts upward approximately 180 degrees, aimed at selfies and casual self-portraiture. However, it lacks the broader articulation of the Olympus, limiting versatility in awkward shooting positions.

Critically, only the Olympus E-M5 II includes an electronic viewfinder (EVF) with 2.36 million dots resolution, providing 100% coverage and a magnification of 0.74x. The GF8 omits any EVF entirely, obliging composition solely via the LCD, which can hamper visibility under bright sunlight, challenging accuracy for manual focusing and exposure.

Burst and Continuous Shooting: Action Photography Considerations

Burst shooting capabilities and buffer depth influence effectiveness in sports and wildlife.

The Olympus E-M5 II offers a respectable 10fps continuous mechanical shutter shooting speed, with shutter speeds up to 1/8000 sec mechanical and 1/16000 sec electronic. This enables capturing fast movement with minimal motion blur.

By contrast, the Panasonic GF8 peaks at 5.8fps with a 1/500 sec mechanical shutter top speed. This shutter speed ceiling significantly restricts capturing fast-action sequences or using faster apertures in bright light without ND filters.

Additionally, the E-M5 II’s full sensor-shift stabilization aids sharper bursts handheld - a distinct advantage in real-world scenarios.
