Over years of hands-on testing, I’ve learned there’s no substitute for digging into technical specs, real-world shooting experience, and user interface to truly understand what a camera offers beyond spec sheets.

In this full-length comparison, I share my direct experience - pixel-peeping sensor output, observing autofocus tracking, pushing frame rates and low-light ISO performance, and assessing ergonomics and handling in varied shooting scenarios. If you’re weighing these two mirrorless contenders for your next investment, this guide will clarify which suits your photography needs, budget, and workflow for portraits, landscapes, wildlife, sports, and beyond.

Let’s start with the fundamentals: size, build, and design.

First Impressions: Size, Handling, and Build Quality

Right out of the gate, the Nikon Z8 and Panasonic S5 reveal significant differences in physical dimensions and feel. The Z8 carries a robust 910-gram body, noticeably larger and heavier than the S5’s 714 grams. The Z8’s SLR-style body is built like a miniature pro flagship, inspired heavily by Nikon’s D850 DSLR ergonomics, offering deep grips, plentiful buttons, and well-placed dial wheels designed for photographers shooting prolonged sessions.

In contrast, the Panasonic S5 lives up to its “travel-friendly” promise - lighter, smaller, and easier to wield with one hand for longer periods. The S5 is ideal for photographers seeking portability and discretion without sacrificing too much handling fidelity.

As someone who frequently tests in high-motion environments - sports venues, wildlife hides, or urban streets - I appreciate the Nikon’s heft as it affords stability with long lenses and in rough weather. However, the Panasonic’s compact and lean design shines in travel and street photography where you want to keep your kit lightweight and inconspicuous.

Weather sealing is present in both, essential for professional reliability. Nikon pushes a bit further here, with a more robust sealing tailored for harsh conditions, including dust and moisture resistance.

Ergonomics-wise, the Nikon Z8 offers illuminated buttons - a boon in dim environments - while the Panasonic S5 lacks this luxury, a small but telling detail on the professional intent behind the Z8’s design.

Control Layout and User Interface: Who Wins the Button Battle?

Moving from the feel to the actual controls, the Nikon’s top-plate sports a secondary info LCD screen - a much-appreciated feature for quick glance info on settings without taking your eye from the viewfinder. The S5 lacks this, leaning on its main LCD and viewfinder for all info display.

The Nikon Z8 embraces extensive customizable buttons, multiple dials, and a classic mode dial with dedicated exposure and ISO controls - tailored for fast access and intuitive operation during challenging shoots. The Panasonic’s control scheme is simpler, with fewer physical buttons - some of which function only through menus or touchscreen - to keep the design clean and approachable for enthusiasts moving up from mirrorless or crop-sensor cameras.

While I found the Panasonic’s menus straightforward and touchscreen responsiveness excellent, complex shooting conditions demand the Z8’s physical controls. For sports or wildlife photographers, this can be the difference between missing or capturing peak action.

Sensor Technology and Image Quality: The Digital Heartbeat

The Nikon Z8 boasts a full-frame 46-megapixel stacked CMOS sensor measuring 35.9x23.9mm, significantly surpassing the Panasonic S5’s 24-megapixel standard CMOS sensor at 35.6x23.8mm. This resolution difference alters the creative possibilities dramatically.

From hands-on pixel-level examination, the Z8’s 46MP sensor delivers exquisite detail and tonality, rivaling Nikon’s flagship Z9 in many respects. The stacked architecture allows ultra-fast readout speeds, aiding in electronic shutter performance and reducing rolling shutter distortion - critical for high-speed photography.

Color depth on the Z8 tops at 26.3 bits (DxO Mark), with a dynamic range of 14.2 stops, allowing exceptionally rich gradations in shadows and highlights. The Panasonic S5, while not yet thoroughly tested by DxO Labs, relies on a traditional CMOS sensor with 24MP resolution, capped at ISO 51200 native (expandable to 204800) but with reduced dynamic range when pushed.

In my experience, Nikon’s sensor excels in large prints and cropping flexibility - essential for landscape and studio work - while the Panasonic’s sensor provides sufficient detail for clients and web-focused workflows, especially when paired with Panasonic’s color science calibrated for skin tones.

Both cameras implement no optical low-pass (anti-aliasing) filter, making images sharper but requiring careful focus and anti-moire handling.

Viewing and Touchscreen Experience: Adjusting on the Fly

The Nikon Z8’s 3.2-inch, 2.1-million-dot tilting touchscreen LCD offers bright, sharp image preview and intuitive menu navigation. Tilting rather than fully articulating limits some shooting angles but improves robustness.

The Panasonic S5’s smaller, fully articulated 3.0-inch 1.84-million-dot screen scores very high marks for flexibility - selfie-friendly and perfect for vloggers or videographers needing versatile angles. Its touchscreen responsiveness is outstanding with smooth focus point selection.

The electronic viewfinder also gives each an identity: the Nikon’s 3.69MP EVF with 0.8x magnification produces a vivid, exact preview with minimal lag - critical for judging focus and exposure in rapidly changing conditions. The Panasonic’s 2.36MP EVF and 0.74x magnification remain good but are noticeably less immersive and detailed.

In the studio or landscape photography, the Nikon’s viewfinder is a delight, while the Panasonic’s articulating screen caters better to video-heavy workflows.

Autofocus Systems: Speed, Accuracy, and Tracking

Nikon’s Z8 advances autofocus technology with 493 on-sensor phase-detection points and full multi-area, eye & animal eye AF - covering a wide portion of the frame for reliable acquisition. The stacked sensor architecture means fast readouts feeding sophisticated AI AF algorithms.

I tested the Z8 extensively on wildlife, and running at 30 frames per second burst with AF/AE tracking, it locked onto moving birds and mammals with uncanny precision and recall. This performance is within touching distance of Nikon’s flagship Z9, making it an able tool for demanding action shooters.

The Panasonic S5, with 225 focus points relying largely on contrast-detection AF, is slower and less confident in low contrast or fast-moving subjects. While face and eye detection perform well in well-lit environments, the absence of phase detection hinders tracking high-speed sports or wildlife.

For portraits and still subjects, both cameras yield sharp precise focus, but the Z8’s comprehensive AF system provides a decisive edge in reliability and speed.

Burst Rates and Buffer Depth: Catching the Decisive Moment

The Nikon’s 30 fps continuous shooting (electronic shutter) and deep buffer make it a powerhouse for sports and wildlife photography, ensuring you rarely miss a fleeting moment. The mechanical shutter still supports a respectable 15 fps.

The Panasonic S5 offers 7 fps continuous shooting with mechanical shutter but no specified electronic burst speed. This makes the S5 less suitable for action-packed environments but quite capable for everyday shooting, portraits, and travel photography.

Both cameras benefit from two card slots, with the Z8 using a CFexpress Type B card slot along with one UHS-II SD slot - ideal for handling high-speed bursts and video workflows - while the S5 uses dual UHS-II SD slots.
