Sensor Technology and Imaging Performance

The heart of any camera is its sensor. Comparing a 24-megapixel full-frame sensor in the Nikon Z5 against the GH5 II’s 20-megapixel Micro Four Thirds chip reveals inherent compromises and benefits rooted in sensor size and architecture.

The Z5 utilizes a CMOS sensor measuring 35.9 x 23.9 mm delivering 24MP resolution with a native ISO range of 100-51200 (expandable to 50-102400). This larger sensor area yields superior light gathering capabilities, enhancing dynamic range, color depth, and noise handling at high ISOs. Additionally, the presence of an optical low-pass filter (anti-aliasing filter) slightly moderates resolution-sharpness trade-offs, favoring artifact suppression in everyday shooting.

Conversely, the GH5 II’s 17.3 x 13 mm Micro Four Thirds sensor achieves 20MP at a minimum ISO of 200 (expandable down to 100 and up to 25600). Notably, the GH5 II omits an anti-aliasing filter, enhancing potential sharpness but at increased risk of moiré and aliasing artifacts in certain textures. Smaller sensor size mandates a 2.1x crop factor, affecting effective focal lengths but enabling more compact optics.

From experiential testing, the Z5 outperforms in low-light conditions with cleaner shadows and less ISO noise at equivalent exposure stops. The GH5 II’s image files demonstrate excellent color rendition and contrast with a slight edge in resolution acuity on high-frequency details under controlled lighting. However, the effective resolution advantage roughly favors the Z5 when considering noise-free enlargements and tonal latitude.

Rear LCD and Electronic Viewfinder (EVF) Comparative Usability

For composition and review, screen quality directly influences user confidence and workflow speed. Both cameras feature electronic viewfinders and rear LCDs with touchscreen capabilities, yet details vary notably.

Nikon’s 3.2-inch tilting LCD sports 1,040k dots resolution, moderate by modern standards, but coupled with a bright and accurate color gamut. The tilt-only mechanism limits angles but reduces mechanical complexity and bulk.

Panasonic’s 3.0-inch fully articulating touchscreen boasts 1,840k dots, representing a substantial leap in resolution and flexibility, essential for vloggers or multi-angle shooting. The articulating arm permits front-facing selfie mode and awkward-angle shooting, unavailable on the Z5.

The EVFs on both models approach 3.7 million-dot resolution with 100% coverage. The Z5’s 0.8x magnification slightly outperforms GH5 II’s 0.76x, providing a marginally more immersive viewfinder experience, though this difference is subtle in field use.

Autofocus Systems: Precision, Tracking, and Focus Modes

Autofocus performance benchmarks require differentiated scrutiny - single-shot accuracy, continuous tracking, eye and animal detection, and operational responsiveness.

The Nikon Z5 adopts a hybrid AF system with 273 phase-detect points overlaying the full frame sensor area, ensuring a broad coverage with advanced eye-detection algorithms for humans and animals. From experience, focus acquisition is reliable and precise in daylight, with slight delays in very low light due to sensor size and contrast sensitivity nuances.

Panasonic’s GH5 II uses contrast-detection autofocus with 225 focus points - optimized with deep learning eye and face detection but lacking phase-detection phase sensors. While this hybrid contrast AF remains responsive in good lighting, continuous AF and tracking, particularly for fast-moving subjects such as wildlife or sports, can show occasional hunting or lag compared to phase-detect systems.

Real-world autofocus testing confirms Nikon’s system suits portraiture and wildlife better owing to phase detection and wider sensitivity, while Panasonic excels in video AF smoothness but may be outpaced in rapid-shooting still scenarios.

Continuous Shooting and Buffer Performance

Burst rate capacity is a critical metric for sports, wildlife, and action photographers. The Nikon Z5 offers a modest 4.5 fps continuous shooting pace, suitable for casual action but insufficient for high-speed sequences. In contrast, the Panasonic GH5 II supports up to 12 fps burst shooting, catering well to dynamic subjects and multi-frame capture demands.

Prolonged burst tests show the GH5 II maintains high-speed shooting longer due to buffer design and faster write speeds on dual UHS-II cards, while the Z5’s buffer fills earlier, necessitating pauses in sustained action shooting.

Image Stabilization Systems

Both cameras incorporate sensor-based 5-axis image stabilization (IBIS), a crucial feature for handheld shooting viability across multiple photography styles.

The Nikon Z5’s IBIS is robust for its class, affording steady images up to approximately 4-5 shutter stops slower than usual handheld limits. This aid proves highly effective in portrait, landscape, and macro usage where tripod avoidance is desired.

The GH5 II’s IBIS system is often regarded as one of the most effective in Micro Four Thirds cameras, with Panasonic’s patented dual IS synergy when combined with compatible lenses. This system benefits video operators and low light photographers alike, reducing motion blur and supporting higher shutter speeds in challenging conditions.
