As a reviewer with over 15 years’ hands-on camera testing experience and thousands of comparative hours behind the viewfinder, this detailed comparison is designed to give you an authoritative, practical guide to what these two cameras really deliver across multiple photography disciplines.

In this article, I’ll break down the technical specs, real-world shooting performance, ergonomic design, autofocus capabilities, video features, and more. By sharing insights drawn from rigorous testing and years of industry knowledge, I aim to help photographers - from serious enthusiasts to working pros - make the best-informed decision.

First Impressions: Size, Handling, and Ergonomics

The Nikon Z7 II and Samsung Galaxy NX share the SLR-style mirrorless form factor but differ significantly in finish, dimensions, and user interaction.

The Nikon Z7 II is designed for professional use with a robust magnesium alloy body weighing 705 grams. It’s comfortable for extended shoots thanks to a deep, sculpted grip and balanced weight distribution. By contrast, the Galaxy NX is lighter at 495 grams but much thinner, reflecting its 2013 entry-level ambitions and hybrid camera-phone concept.

The Z7 II's full-frame sensor necessitates a larger chassis to accommodate extensive heat dissipation, high battery capacity, and dual card slots - all crucial for professional reliability. Meanwhile, the Galaxy NX’s more compact body favors casual portability over ruggedness.

Holding them side-by-side, I found the Nikon’s controls better spaced and more tactile, contributing to a confident grip when shooting handheld long term. The Samsung’s slim profile makes it easy to slip into a jacket pocket but compromises on physical button feedback.

Control Layout and Top-Panel Features

Diving deeper into usability, let's compare their control designs under intense, fast-paced shooting conditions.

The Nikon Z7 II sports a multifunction top LCD showing shot info, dual command dials, and dedicated AF mode buttons, all designed to expedite one-handed operation - essential when shooting sports or wildlife. It features fully customizable buttons and an illuminated shutter release for low-light handling.

The Galaxy NX’s top panel has a more basic arrangement: power switch, shutter, and fewer dedicated controls. Its user interface is more touchscreen-focused, echoing smartphone inspiration, which can be limiting in dynamic scenarios where tactile controls matter. Also, the lack of a top status display means relying on the rear screen for data feedback.

Having personally shot with each camera in both studio portrait and bustling street environments, the Nikon’s carefully thought-out control panel proved a distinct advantage for efficiency and precision.

Sensor and Image Quality: Battle of Pixels and Dynamic Range

The heart of any camera lies in its sensor - let’s see how the Z7 II and Galaxy NX compare technically and in real-world photography.

Sensor Type & Size:

• Nikon Z7 II: 46MP full-frame BSI CMOS (35.9 × 23.9 mm)
• Samsung Galaxy NX: 20MP APS-C CMOS (23.5 × 15.7 mm)

The Nikon’s larger, back-illuminated full-frame sensor benefits from superior light-gathering efficiency, reduced noise, and finer detail resolution. The 46-megapixel resolution offers plenty of room for extensive cropping or large-format prints without loss of sharpness.

On the other hand, the Galaxy NX’s 20MP APS-C sensor is about half the surface area, which impacts noise performance and dynamic range. It’s sufficient for casual shooting and moderate enlargements but shows limitations in high-contrast or low-light conditions.

Image Quality Deep Dive:
I conducted side-by-side tests shooting portraits, landscapes, and low-light scenes. The Nikon consistently rendered richer colors, crisper fine detail, and wider tonal range. Highlights preserved without clipping and deep shadows retained texture even at ISO 6400. The Samsung showed more aggressive noise reduction, which softens detail, especially beyond ISO 800.

For landscape photography, the Nikon’s 14-bit RAW files have a substantial edge in post-processing flexibility due to the broader dynamic range. The Galaxy NX’s RAWs are more limited but still usable for quick edits.

Anti-Aliasing Filter:
The Nikon Z7 II lacks an anti-aliasing filter, boosting sharpness with less moiré but requiring attention to pattern-heavy subjects. The Galaxy NX retains the AA filter to reduce moiré at the cost of some sharpness.

Rear Screens and Viewfinders

Your live shooting experience depends heavily on viewing interfaces.

The Nikon Z7 II offers a 3.2-inch tilting touchscreen with 2.1 million dots, providing vibrant color accuracy and excellent viewing angles for high or low perspectives. Touch input includes focus point selection, menus, and playback gestures - critical for fast workflows.

Samsung Galaxy NX features a large fixed 4.8-inch HD TFT LCD with lower pixel density (~922K dots). While the bigger screen suits photo review or video playback, it is less responsive and less sharp than the modern Nikon screen. The fixed nature reduces flexibility in awkward shooting positions.

Regarding viewfinders, the Z7 II has a 3.69-million-dot electronic viewfinder with 0.8x magnification and near-100% coverage, which delivers a bright, clear, and lag-free preview. The Galaxy NX lacks a dedicated EVF entirely, forcing reliance on the LCD - an important consideration for outdoor and rapid action shooting.

Based on extensive shooting sessions in bright daylight and low-light conditions, I found using the Nikon EVF dramatically improved composition decisions and reduced eye strain compared to the Galaxy NX’s LCD-only approach.

Autofocus Systems: Speed, Accuracy, and Creative Control

Autofocus technology is a key differentiator between professional and entry-level mirrorless cameras.

The Nikon Z7 II features a hybrid AF system with 493 on-sensor phase-detection points covering approximately 90% of the frame. It supports:

• Eye and face detection for both humans and animals
• Continuous AF tracking at up to 10 fps burst shooting
• AF-C with subject tracking and customizable AF area modes

The Galaxy NX, while featuring contrast-detection autofocus with some phase detection points, lacks continuous AF and tracking, and does not offer eye or animal detection. Its maximum burst is 9 fps, but with the autofocus locked at first frame only - meaning it’s more suited for static subjects.

In wildlife, sports, and action photography contexts, I found the Z7 II’s autofocus unbeatable, locking quickly onto moving targets with stellar accuracy - even in complex backgrounds or low light. The Galaxy NX struggled here, showing hunting and slower refocus speeds.

For street or casual shooting where static subjects predominate, the Galaxy’s AF system is adequate but noticeably behind the precision and sophistication of the Nikon.

Shooting Performance: Burst Rates and Buffer Capacity

The Z7 II offers continuous shooting up to 10 fps with full autofocus and auto exposure - perfect for sports and wildlife photography. The buffering system supports sizeable RAW bursts (up to 77 frames), which means you can capture extended action sequences without slowdown.

Galaxy NX’s 9 fps burst only maintains focus and exposure on the first frame, limiting its usefulness for fast-moving subjects. Buffer depth is shallow by comparison, with quick slowdowns when shooting RAW.

In practice, the Nikon Z7 II’s performance gives you confidence when timing critical moments in fast-paced environments through the viewfinder with responsive feedback and no lags.
