If you’re someone who values a refined, no-nonsense interface with classical Leica styling, the SL2-S feels like a trusted tool. The Z8 appeals more to those who want abundant direct controls at their fingertips and a slightly more aggressive ergonomic stance for extended shooting.

Sensor and Image Quality: Resolution, Dynamic Range, and ISO Performance

At the heart of any camera is its sensor and image processor, dictating the fidelity, color depth, and noise handling you can realistically expect.

The Leica SL2-S houses a 24MP full-frame CMOS sensor without an anti-aliasing filter - a deliberate choice to maximize resolution and detail rendering while sacrificing a hint of moiré control. Leica opted for a pure CMOS (non-stacked) sensor and favors a wide native ISO range (50 to 50,000). This sensor strikes a commendable balance for users prioritizing high-quality stills and video shooting with excellent color rendition and skin tone accuracy.

In contrast, the Nikon Z8 boasts a 46MP stacked CMOS sensor, delivering nearly double the resolution at 8256 x 5504 pixels. This larger pixel count translates into greater cropping flexibility, super-sharp landscape details, and highly nuanced texture rendering. Nikon’s newer sensor architecture, combined with advanced on-chip phase-detection autofocus pixels, enables exceptionally fast readout speeds and reduced rolling shutter artifacts.

Dynamic Range & Low Light: According to DxOMark benchmarks, the Nikon sensor scores impressively in color depth (26.3 bits) and dynamic range (14.2 stops), with a noted low-light ISO advantage (ISO 2548 effective). Leica’s sensor isn’t officially benchmarked yet but performs admirably in field tests with smooth tonal gradation and excellent shadow recovery around ISO 1600-3200. The Z8's broader ISO range, extending up to 102,400 boosted, edges out when working under extreme low light, such as astrophotography or dim concert venues.

For photographers prioritizing high-res detail and a wider dynamic latitude, the Nikon Z8 sensor offers a compelling advantage. Conversely, those preferring the tested, proven image characteristic of Leica sensors will relish the SL2-S’s excellent color science and tonality for portraits and everyday shooting.

Intuitive Touchpoints: LCD and Viewfinder Experience

The electronic viewfinder (EVF) and rear LCD are crucial for composition, real-time preview, and menu navigation, especially in dynamic shooting environments.

Both cameras feature 3.2-inch screens with roughly comparable 2.1-million-dot resolution and touchscreen functionality. The Leica SL2-S uses a fixed display, which works well for stable tripod shooting or controlled studio sessions. It’s bright, sharp, and responsive with color reproduction that aligns well with final JPEG output.

The Nikon Z8’s 3.2-inch screen is tilting, offering more flexibility for shooting at awkward angles or capturing low perspectives on the fly - an edge for event and street photographers. Its menu system is layered but highly customizable, sometimes daunting initially but rewarding once mastered.

Regarding EVFs, the SL2-S has a top-tier 5760-dot resolution with 0.78x magnification, offering a crisp, bright, and sizeable viewing window. Nikon’s Z8 uses a slightly smaller magnification (0.8x) with a 3686-dot EVF, still excellent but less detailed in comparison. The higher resolution Leica EVF excels in nuanced manual focusing, while the Nikon’s EVF feels fluid during rapid burst action or video tracking.

Autofocus Systems: Speed, Accuracy, and Tracking Robustness

Autofocus can make or break many shooting situations - no one wants to miss the decisive moment because the camera hesitated.

The Leica SL2-S relies on a contrast-detection autofocus system with 225 AF points and face detection. While contrast detection is traditionally slower than phase detection, Leica's latest SL2-S firmware updates have optimized its AF for snappy acquisition in good light. However, it lacks on-sensor phase detection and animal eye AF, which some photographers feel limits its effectiveness in fast wildlife or sports shooting.

The Nikon Z8 integrates a sophisticated hybrid system with 493 autofocus points using both phase- and contrast-detection pixels spread across nearly the entire frame. Its AF excels in continuous tracking, with top-tier subject recognition and animal eye autofocus - a real boon when capturing unpredictable wildlife or fast-moving athletes. Users will find the Z8 especially adept in low light, where AF is notoriously challenging, maintaining firm focus lock when many competitors struggle.

Burst and AF Tracking:

• Leica SL2-S offers a very fast 20fps continuous shooting with full AF/AE tracking, impressive for a 24MP sensor.
• Nikon Z8 speeds ahead at 30fps electronically, with flawless AF tracking across bursts thanks to its stacked sensor design.

For photographers specializing in sports, wildlife, or high-speed events, Nikon’s AF system is the superior choice. Leica’s SL2-S AF performs admirably in portraits, landscapes, and studio environments but isn’t optimized for rapid action.

Durability and Weather Sealing: Ready for Rugged Environments?

Both cameras finish with environmental sealing, designed to resist dust and moisture ingress during fieldwork.

The SL2-S touts weather sealing against dust and splash, a must-have for Leica’s traditional outdoor and reportage users. Build quality is rock-solid with a magnesium alloy frame, reassuring for heavy-duty professional use. However, Leica does not explicitly claim freezeproof or shockproof ratings.

Similarly, the Nikon Z8 offers professional-level weather sealing in a rugged magnesium alloy body, suitable for extended use in harsh environments. Its dual card slots (CFexpress and UHS-II SD) help ensure safe data backup in critical assignments. Though neither is "weatherproof" per se, they are constructed to withstand typical rain, dust, and cold conditions encountered by pro photographers.
