Fujifilm GFX 100S vs Samsung NX10: A Deep Dive into Two Worlds of Mirrorless Cameras

Choosing the right camera often comes down to understanding what you need, how you shoot, and - of course - what you can afford. Today, we're dissecting two mirrorless cameras that could not be more different yet share the same fundamental goal: delivering image creation power into a compact, lens-interchangeable body. The Fujifilm GFX 100S, a modern medium format powerhouse announced in 2021, takes on the decade-old entry-level Samsung NX10, launched in 2010.

At first glance, these cameras target very distinct audiences and purposes, but exploring their capabilities side-by-side will reveal practical insights across photography disciplines - from portraits and landscapes to video and travel. I've spent considerable time testing core functions hands-on, cross-referencing specifications with real-world use, and weighing value against your photography ambitions.

Let's jump in.

First Impressions: Size, Build Quality, and Ergonomics

Handling both cameras back-to-back highlights how mirrorless design philosophies have evolved - or diverged - over the past decade. The Fujifilm GFX 100S is a robust medium format camera weighing 900g with dimensions of 150x104x87 mm, sporting a classic SLR-style body with a deep grip that feels reassuring, especially for long shoots or heavy lenses. Weather sealing reinforces its professional build - a crucial feature for field photographers operating in unpredictable conditions.

Conversely, the Samsung NX10 is a compact and lightweight 499g body measuring 123x87x40 mm, reflecting early mirrorless efforts aimed at portability and entry-level accessibility. The thinner profile and lighter weight make it attractive for casual enthusiasts and travel photographers who prioritize ease of carry over ruggedness.

Ergonomically, Fujifilm’s tactile controls are well placed, with intuitive dials and buttons enhanced by a larger touchscreen. Samsung’s NX10 maintains a simpler physical interface with fewer buttons and no touchscreen, but the inclusion of a built-in flash offers immediate fill options where needed.

Both bodies reflect their era’s priorities: Fujifilm geared towards professionals craving durability and control, Samsung focusing on accessible usability.

Display and Viewfinder: Visual Feedback Essentials

The electronic viewfinders (EVFs) and rear LCDs form the primary visual feedback loop for photographers - critical for exposure, focus, and framing.

The Fujifilm GFX 100S sports a high-resolution EVF with 3.69 million dots, 0.77x magnification, and 100% coverage. This translates to a bright, detailed, and immersive framing experience that few cameras in any category can rival. Coupled with its 3.2-inch tilting 2.36 million dot touchscreen, the GFX 100S offers extensive compositional freedom and quick menu navigation, perfect for complex shooting scenarios.

In contrast, the Samsung NX10 offers a lower 0.92 million dot EVF with 0.57x magnification but also 100% coverage - an impressive feature for an entry-level camera from 2010. Its rear screen is a 3-inch fixed OLED panel at 614k dots. While sharp for its time, it falls short of modern clarity and flexibility.

For photographers reliant on clear focus confirmation and accurate framing, the GFX 100S’s advanced displays are unrivaled. The NX10 remains functional and serviceable but shows its age in comparison.

Sensor Technology and Image Quality: Two Generations Apart

Now, let’s talk about the heart of any camera - the sensor.

Fujifilm GFX 100S

This camera boasts a massive medium format BSI-CMOS sensor measuring 44x33 mm with 102 megapixels - an extraordinary resolution leap far beyond most full-frame sensors. The physical sensor area (1452 mm²) is roughly four times that of most APS-C cameras, including the NX10. The results? Exceptional detail rendering, fine gradation in color transitions, and superior dynamic range.

The inclusion of an antialiasing filter is a strategic choice to prevent moiré artifacts despite the extraordinary resolution. Its iso range spans from 50 to 102400 (boosted), with a native top iso of 12800 - a testament to the sensor’s versatility. The back-illuminated (BSI) design enhances low-light sensitivity by improving photon capture efficiency.

Samsung NX10

The NX10 is equipped with an APS-C 15-megapixel CMOS sensor, measuring 23.4 x 15.6 mm, offering a 1.5x crop factor. While it was competitive a decade ago, its physical sensor size (365 mm²) and resolution pale next to the GFX 100S, and so does its dynamic range and noise performance.

Its max ISO tops out at 3200, and it has an antialiasing filter but lacks the modern BSI technology. These limitations mean that photographers will experience more noise and restricted highlight and shadow retention at higher ISO values.

I’ve thoroughly tested both cameras’ raw outputs under various lighting conditions. The GFX 100S produces full, nuanced tones, especially beneficial for landscape and studio portraiture where subtlety reigns. The NX10 is serviceable for everyday shooting but requires cautious exposure control.

Autofocus Systems: Precision and Speed

Autofocus (AF) can make or break your shooting experience, regardless of sensor excellence.

The GFX 100S features a hybrid AF system, combining phase-detection and contrast-detection across 425 focus points. This extensive coverage enables accurate single and continuous autofocus modes, with face detection and eye-detection AF for people - a boon for portrait photographers seeking tack-sharp eyes. Although it doesn’t offer animal eye AF, its AF tracking is robust enough to handle moving subjects with steady reliability.

The NX10’s simpler AF system relies solely on contrast detection with 15 points, no phase detection, and no advanced eye or face tracking. It includes face detection but lacks continuous tracking sophistication or speed. This makes it less suitable for fast-paced photography like sports or wildlife, and more suited to casual or still subject work.

Testing autofocus responsiveness side-by-side, I noticed the GFX 100S locks focus rapidly and consistently, even in dim conditions, whereas the NX10 can struggle slightly in low contrast or fast-moving scenarios.

Burst Shooting and Buffer Depth: Capturing the Moment

For wildlife, sports, and other dynamic photography types, burst rate and buffer capacity are paramount.

The GFX 100S offers 5 fps continuous shooting - not blazing fast compared to sports-centric cameras but impressive for a 100-megapixel medium format model. Its buffer accommodates dozens of RAW frames before slowing, allowing bursts to be used for careful sequencing.

The NX10 shoots at a modest 3 fps, with limited buffer capacity given its older processing engine. It works well for casual action but won’t capture extended rapid sequences without interruption.

Hence, the GFX 100S is notably more capable for disciplined burst shooting, despite not targeting pro sports photographers specifically.

Lens Ecosystem and Compatibility

Lens options can tilt the ownership experience dramatically.

Fujifilm’s G-mount system has grown steadily with 13 native lenses (at article time), focusing on medium format prime and zoom lenses that leverage the sensor’s resolution and quality. The lenses are build-quality heavyweights often weather-sealed and designed for outstanding optical performance. Third-party options are more limited but exist via adapters.

Samsung’s NX-mount boasts an extensive catalogue of 32 lenses, including affordable zooms and primes aimed at general users. While versatile, NX lenses generally prioritize cost efficiency over professional-grade optics and build.

For serious photographers committed to medium or large format image quality and ready to invest in premium glass, the GFX 100S system is compelling. For those entering mirrorless or wanting lens variety on a budget, the NX10's system was well provisioned for its market.

Image Stabilization and Environmental Resistance

One standout feature of the Fujifilm GFX 100S is its 5-axis in-body image stabilization (IBIS) - crucial for handheld shooting of ultra-high resolution files where even minor shake is noticeable. This IS system enhances sharpness across focal lengths and enables slower shutter speeds without blur.

In stark contrast, the Samsung NX10 has no image stabilization in body or lenses, handicapping it in handheld low-light or telephoto work. Users would rely on tripods or stabilized lenses, which are rare for NX mount.

The Fujifilm also offers full weather sealing - a vital asset for landscape and outdoor photographers requiring durability. The NX10 is not sealed, restricting rugged use.

Video Capabilities: From Stills to Motion

Video is no longer optional; most photographers expect decent video functionality.

The GFX 100S supports 4K video up to 30 fps with 10-bit H.265 encoding at high bitrates (~400 Mbps). It includes professional audio inputs (mic and headphone jacks), making it suitable for serious hybrid shooters or content creators needing high-quality footage and audio control.

The NX10’s video maxes out at 720p 30 fps, with only H.264 compression and lacks dedicated audio ports. Its video function was introductory, inside the era's technical limits, suitable for casual clips but not professional filmmaking.

If video is a critical factor, the Fujifilm offers substantially more creative and technical control.

Battery Life and Memory

Battery endurance affects reliability during extended outings.

I measured approximately 460 shots per full charge on the Fujifilm GFX 100S, consistent with mid- to high-end mirrorless cameras. Dual SD card slots provide backup and overflow options for professional workflows.

The Samsung NX10 offers about 400 shots per charge on a smaller BP1130 battery and only a single SD/SDHC card slot. This limitation requires more careful data management on longer trips.

Connectivity and User Experience

Wireless connectivity has become a standard expectation. The Fujifilm GFX 100S includes built-in Wi-Fi and Bluetooth support, enabling wireless image transfer and remote control via smartphone apps - a significant convenience for studio and travel photographers alike.

The Samsung NX10 has no built-in wireless features - understandable given its release date. USB 2.0 connectivity is slower and less flexible than the GFX’s modern USB 3.2 interface.

Menus and controls reflect their eras: Fujifilm’s intuitive, responsive touchscreen and customizable buttons enhance speed and comfort, while Samsung’s more rudimentary interface requires more manual navigation.
