On the other, there's the Z8, Nikon’s latest powerhouse, which seems designed to eclipse many traditional flagship models with prodigious resolution, sophisticated autofocus, and video features.

Having spent extensive hours testing both models in diverse real-world scenarios - from portrait studios to wild forests, fast-paced sports arenas to night skies - I’m here to offer an authoritative, practical comparison tailored to photographers and serious enthusiasts alike. This article dives deeply into sensor tech, autofocus systems, handling, optical performance, video abilities, and more, ultimately empowering you to decide which camera best aligns with your photographic pursuits and budget.

First Impressions: Size, Ergonomics, and Build Quality

Let's start with the tactile experience, which often influences whether a camera feels like an extension of your creative intent - or a hurdle.

Right out of the box, the Nikon Z5 impresses with its compact, relatively lightweight body weighing around 675 grams. It retains a classic SLR-style mirrorless form factor, blending modern mirrorless design with robust ergonomics. I found the grip comfortable for long shoots, with well-placed buttons suited to intuitive operation. This makes the Z5 a compelling option for travel enthusiasts and those favoring portability without compromising stability.

Compare this to the Z8, which at 910 grams and larger dimensions (144x119x83 mm) feels substantial in hand - almost like a DSLR yet streamlined. This heft translates into a commanding presence and contributes to the camera’s exceptional durability and professional handling. The body sports more pronounced weather sealing and a refined layout that caters to professionals accustomed to intensive shoots across challenging environments.

On the top plate, the Z8 features more physical controls, including a dedicated ISO dial, an exposure compensation dial, and customizable buttons with illumination - a boon for low-light shooting. The Z5 keeps controls simpler, geared toward ease of use rather than exhaustive customization. Both cameras use the same Nikon Z mount, ensuring lens compatibility, but the Z8’s design more directly facilitates quick access, which professionals will appreciate during dynamic sessions.

Sensor Technology and Image Quality - A Tale of Two Resolutions

Now to the core of both cameras - their sensors and resulting image quality, which lie at the heart of photographic output.

The Z5 sports a 24.3-megapixel full-frame CMOS sensor paired with Nikon’s Expeed 6 processor. This setup is tried-and-true, providing excellent color accuracy and usable ISO sensitivity up to 51200 (expanded to 102400). While it has an anti-aliasing filter - slightly softening images compared to sensor designs without one - the sensor performs extremely well for general photography and delivers pleasing dynamic range suitable for landscapes and portraits.

By contrast, the Nikon Z8 boasts a 45.7-megapixel stacked CMOS full-frame sensor, doubling the resolution while incorporating backside illumination to enhance light collection efficiency. The sensor pairs with a more advanced processing pipeline supporting superior noise control and an impressive dynamic range of 14.2 EV stops measured in lab tests. This high pixel count and rapid readout facilitate not only detailed stills but also cutting-edge video options (more on this later).

From hands-on examination of RAW files, the Z8’s images show greater resolving power, richer fine detail, and smoother tonal gradations. In low-light conditions, the Z8 maintains cleaner shadows with less chromatic noise even at high ISOs, outperforming the Z5 which begins to present noise artifacts fairly early when pushed past ISO 3200.

For photographers prioritizing the sharpest imagery with flexibility in cropping or large prints, the Z8 is unbeaten in this duo. The Z5 corresponds well for users who want excellent full-frame quality without the file size management challenges that come with ultra-high resolution.

Autofocus Systems: Precision, Speed, and Tracking

In today’s fast-paced photographic workflows, autofocus (AF) performance directly affects user experience and success rate - especially in genres like wildlife and sports.

Both cameras employ hybrid autofocus systems that integrate phase-detection with contrast detection points on the sensor. They support face and animal eye detection, a serious boon for portrait and wildlife shooters.

That said, technical specs reveal a significant divergence:

The Z5’s autofocus performs admirably for general subjects but can occasionally disappoint tracking fast-moving subjects, especially under challenging lighting. Svelte and deliberate, it suits portraiture, landscape, and casual wildlife but doesn’t quite keep pace with extreme sports or rapid animal movement.

Conversely, the Z8 shines with 493 strategically placed focus points that cover most of the frame. Its processing horsepower allows for continuous AF at up to 30 frames per second with precision tracking, making it one of the top competitors in pro mirrorless autofocus performance I’ve tested. The eye-detection is fast and reliable - even with erratic movement and in trickier lighting - delivering consistently sharp results for athletes, birds in flight, and other demanding subjects.

Screens and Viewfinders: Composing Your Vision

Both cameras feature 3.2-inch tilting touchscreens, yet differences lurk beneath the surface:

The Z5’s rear LCD offers 1.04 million dots resolution, sufficient for framing and reviewing images, but less vibrant and detailed compared to the Z8’s 2.09 million dots display. The latter facilitates critical assessment of focus sharpness and exposure on the spot, a must-have for professionals on tight deadlines.

The electronic viewfinders (EVF) are roughly equivalent in size and coverage with 0.8x magnification, but the Z5 sports slightly higher resolution at 3690k dots versus 3686k on the Z8 - an almost negligible difference. The Z8’s EVF additionally features faster refresh rates and minimal blackout during continuous shooting, enhancing stability during sports or wildlife sequences.

Lens Ecosystem and Compatibility: Ready for Every Shot

Both cameras share the Nikon Z mount, which is a major strength given the richness of Nikon’s growing Z lens lineup.

• Z5 is compatible with 15 native Z lenses, covering essentials from wide-angle to telephoto.
• Z8 supports 46 native Z lenses, including pro-level optics like the NIKKOR Z 400mm f/2.8 TC VR S and ultra-high-performance primes.

Given that many Nikon F-mount DSLR lenses can be adapted via FTZ mounts with minimal compromise, either camera can fit into an existing Nikon ecosystem. Yet, the Z8 is clearly targeted at photographers requiring the highest optical capability, with greater lens selection to unlock creative flexibility.
