Nikon Z7 vs Samsung NX20: Hands-On Expert Comparison for Serious Photographers

Choosing your next mirrorless camera can feel a bit like navigating a labyrinth, especially with so many options spanning different tech generations and price points. Today, I’m placing two very different beasts side-by-side: Nikon’s flagship full-frame Z7 (2018) versus the more budget-friendly Samsung NX20 (2012). Both boast mirrorless designs and SLR-style ergonomics, but they embody different eras of tech and cater to distinct user priorities. Having personally tested thousands of cameras over 15+ years, I want to give you a no-nonsense, practical breakdown on how these two perform across various photography disciplines - and which one might serve you best in the real world.

So buckle up for a detailed yet digestible comparison, peppered with clear recommendations and unique insights you won’t find in typical spec sheets.

First Impressions: Size, Build, and Ergonomics at a Glance

The moment you pick up the Z7 and NX20, the difference in physicality is immediately obvious.

Nikon Z7 comes in as a robust and professional-grade mirrorless camera weighing 675g with a full-frame sensor housed in a solid, weather-sealed body (something I really appreciate for outdoor use). Its dimensions are a comfortable 134x101x68mm, with a deep handgrip that invites long shooting sessions without cramps. The build quality feels like Nikon intended this to be a dependable partner for pro workflows.

In contrast, the Samsung NX20 is noticeably smaller and lighter at 341g, with dimensions of 122x90x40mm. Although it too sports an SLR-style design, it errs more on the compact and portable end of the spectrum. It doesn’t have the environmental sealing that the Z7 offers, which is something to consider if you shoot in challenging weather or dusty environments.

Ergonomically, the Z7 benefits from a larger, more sculpted grip and larger buttons/clubs for your thumbs, while the NX20 feels a bit more toy-like in the hand - but for street or travel photographers craving portability, that’s a plus.

Control Layout and User Interface: Intuitive or Clunky?

Handling and interface directly impact how quickly you can adapt and get the shot.

Nikon’s Z7 displays a classic top-plate setup with dedicated dials for ISO, shutter speed, exposure compensation, and a handy top-status LCD panel. These physical controls are a joy to reach without taking your eye off the viewfinder - a boon for fast-moving scenes or manual shooters. It features touch-sensitive AF point selection, a customizable multi-selector, and illuminated buttons for low-light work.

The Samsung NX20’s top plate is more minimalistic, with standard control dials but lacks that handy top LCD display. Its AF point selection relies on directional pads rather than touch, and some buttons feel a bit small and plasticky - a bit fiddly if you have bigger hands or gloves.

Both have full electronic viewfinders (EVFs), though the Z7’s EVF boasts a much higher resolution (3,690k dots vs. the NX20's less defined due to unavailable specs), making live previews and manual focusing easier on the eyes.

Sensor Technology and Image Quality: Why Full-Frame Still Rules

The heart of any camera is the sensor, and here’s where the Z7 flexes its muscles hard - its 45.7-megapixel full-frame BSI-CMOS sensor dwarfs the NX20’s 20.3-megapixel APS-C CMOS sensor. Sensor size means everything when it comes to noise performance, dynamic range, and depth of field control.

Why does sensor size matter?

• Dynamic range: The Z7’s 14.6 stops measured dynamic range lets it capture very detailed highlights and shadows, which is invaluable for landscape and high-contrast shooting. The NX20 is respectable here but maxes out around 12.9 stops, showing slightly less latitude in tough lighting.

• Color depth: Nikon’s 26.3 bits color depth vs. Samsung's 23.4 bits means smoother tonal gradations and richer colors from RAW files after editing.

• ISO performance: The Z7 excels at high ISO shooting, with usable ISO up to 25,600 and boosted settings even beyond that, while the NX20’s low-light capabilities top out around ISO 12,800 with significantly more noise.

• Resolution: The Z7’s whopping 8,256 x 5,504 max resolution delivers stunning image detail - ideal for large prints and commercial work. The NX20’s 5,472 x 3,648 resolution certainly captures plenty, but fine detail and cropping flexibility are more limited.

Simply put, from a pure imaging standpoint, the Nikon Z7 is in an entirely different league, mainly due to modern sensor technology and processing.

LCD and Viewfinder: Bringing the Scene to Life

Both cameras offer electronic viewfinders and LCDs that assist visualizing shots, but their quality varies.

The Z7 features a 3.2-inch tilting touchscreen LCD, with a dazzling 2,100k-dot resolution - for sharp menus and easy touch AF point selection. The tilting design gives you flexibility for low or high angle shots. The crisp EVF coupled with touchscreen input suits hybrid shooters who switch quickly between manual and autofocus methods.

Samsung’s NX20 opts for a 3-inch fully articulated AMOLED screen (active matrix OLED technology). This is a plus for video shooters and selfies - something rare at the time for mirrorless cameras. However, it lacks touchscreen functionality, which can slow down AF adjustments.

For tactile interfaces and usability during dynamic shooting, the Z7 edges ahead, especially with color-accurate LUTs on the screen.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus (AF) systems are critical for fast and accurate subject capture, especially in sports, wildlife, and action photography.

• Nikon Z7: 493 phase-detect AF points distributed across the sensor offer precise subject detection and tracking. It features eye-detection AF for humans and animals (a killer feature for portrait and wildlife shooters). The camera excels with continuous AF and tracking moving subjects with high reliability.

• Samsung NX20: Employs contrast-detection AF with 15 selectable points - not nearly as responsive or effective for moving subjects. It includes face detection but lacks eye or animal detection. This is comfortably sufficient for static scenes and casual shooting but will frustrate you in fast action.

In my hands-on testing, the Z7 seamlessly tracked birds in flight and fast-moving athletes with remarkable consistency. The NX20’s autofocus lag became painfully obvious in such scenarios.

Burst Rates and Buffer: Freezing the Action

For sports and wildlife photographers, burst rates and buffer memory capacity can make or break decisive moments.

• Nikon Z7: 9 fps continuous shooting at full resolution with a sizable buffer capable of capturing dozens of RAW frames before slowing down.

• Samsung NX20: 8 fps continuous shooting, but with slower buffer clearance and limited RAW capture depth.

Both are respectable, but the Z7’s faster processor and newer sensor design grant it better sustained shooting - key for high-speed bursts in demanding scenarios.

Lens Ecosystem and Compatibility: The Glass that Defines Your System

A camera is only as good as its lenses. Nikon’s Z7 uses the Nikon Z mount, which has rapidly grown since 2018, boasting 15 high-quality native lenses, covering everything from ultra-wide landscapes to super telephoto wildlife glass. Nikon’s traditional F-mount lenses can be adapted without losing AF functionality, thanks to their FTZ adapter.

Samsung’s NX system, meanwhile, uses the Samsung NX mount with a lens lineup that peaked around 32 lenses during the brand’s mirrorless years. These lenses are generally less available today and fewer third-party choices exist. Adapters for other mounts are limited, so you’re effectively locked into what Samsung created - mostly older, smaller lenses.

This difference means if you’re investing long term, Nikon’s ecosystem offers far more flexibility and future-proofing.

Battery Life and Storage: Shooting More Without Interruptions

Battery life is often overlooked but critical - no matter your photography discipline.

• Nikon Z7 provides approx 330 shots per charge (CIPA rating) using the EN-EL15b battery, which is decent but you’ll want spares for events or travel.

• Samsung NX20 boasts slightly better longevity at 360 shots per charge, partly due to its smaller sensor and less power-hungry processor.

Storage-wise, Z7 uses the modern, ultra-fast XQD cards enabling rapid write speeds beneficial for large RAW files and 4K video. NX20 relies on SD/SDHC/SDXC cards, which are more ubiquitous and cost-effective but slower.

Video Capabilities: Moving Images Compared

Video shooters, take note:

• Nikon Z7 offers 4K (3840x2160) at 30fps with clean HDMI out, microphone and headphone jacks - features appreciated by serious videographers. In-camera stabilization (sensor-shift 5-axis) smooths handheld footage.

• Samsung NX20 caps out at 1080p (FHD) 30fps, no 4K option, micro-HDMI is present but only microphone input, no headphone jack, and lacks internal stabilization.

If video is a key part of your work, the Z7 is much more capable both technically and ergonomically.

Real-world Photography Performance: A Gallery Walk-Through

To give these cameras a proper test, I shot portraits, landscapes, wildlife, and street scenes side-by-side under varied lighting conditions.
