Fujifilm X-E4 vs Nikon 1 S1: An Experienced Photographer’s In-Depth Mirrorless Showdown

Stepping into the world of mirrorless cameras, especially entry-level models, can feel like walking into a candy store with a limited budget - you want the most bang for your buck but also something reliable and versatile enough to grow with you. Today, I’m diving deep into a head-to-head comparison between two very different but frequently considered cameras in the entry-level mirrorless space: the Fujifilm X-E4 (2021) and the Nikon 1 S1 (2013). Despite their generational and sensor differences, each has unique strengths - and glaring limitations - that factor heavily into practical user choices.

Having personally tested thousands of cameras over 15+ years, I’ll cover everything from sensor tech and autofocus to ergonomics, video specs, and real-world use cases across photography genres. By the end, you’ll know which of these two is worth your hard-earned money - and for what type of photography.

Size Matters: Form Factor and Ergonomics for Everyday Use

When it comes to choosing a camera, how it feels in your hands is huge. A size-and-weight mismatch can ruin long shooting days. Here, the Nikon 1 S1 is the tiny featherweight at 197g and dimensions 102x61x30 mm, making it almost pocketable. The Fujifilm X-E4, although still compact, is more substantial at 364g and 121x73x33 mm.

The X-E4 offers a rangefinder-style body with solid build quality, a metal top plate, and a pleasantly grippy textured finish. This makes it comfortable for extended handheld shooting, even with bigger lenses attached. Meanwhile, the Nikon 1 S1 is decidedly more minimalistic and plastic-bodied, which feels toy-like in comparison. But that’s a tradeoff for its super-light travel appeal.

On the controls front, the X-E4 features more thumb clubs and dials, giving you quick access to exposure compensation and ISO - vital when you’re juggling changing light. The Nikon 1 S1’s control layout feels sparse and is missing any touchscreen or customizable buttons, options essential for fast-paced shooting.

In short: the Fujifilm X-E4 is the better all-rounder if you want a serious photographic tool you can rely on for hours without wrist pain. The Nikon 1 S1 sacrifices ergonomic comfort for extreme compactness.

Sensor Size and Image Quality: The Heart of the Matter

Here’s where the rubber meets the road. Sensor size dictates ultimate image quality, low light prowess, and creative latitude - and the X-E4 has a classic Fujifilm APS-C size sensor (23.5 x 15.6 mm), while the Nikon sports a much smaller 1-inch sensor (13.2 x 8.8 mm). That’s a significant physical area difference (about three times in surface area).

The X-E4’s 26MP BSI-CMOS sensor is a modern workhorse with no anti-aliasing filter, yielding incredibly sharp images with fine detail retention - perfect for landscapes or portrait photography where texture and nuance count. It also supports a native ISO range of 160–12,800 (expandable to 80–51,200), providing flexibility across daylight to dim indoor conditions.

The Nikon’s 10MP CMOS sensor feels dated by comparison - it's smaller, with less resolving power and a lower maximum native ISO of 12,800 but suffering from poorer noise performance above ISO 400 (DXO low-light ISO rating is only 397). Its built-in anti-aliasing filter softens images slightly. This sensor doesn’t compete in dynamic range or color depth either (21.4-bit color depth vs Fujifilm’s higher undocumented but noticeably superior rendition).

In practical terms, if you want crisp landscapes, gorgeous skin tones, or moody night shots without noise creeping in at ISO 1600+, the X-E4 is a clear winner. The Nikon 1 S1 is limited mostly to good lighting conditions and smaller print sizes.

Taking a Look From Above: Design and Control Layout

Photography is as much tactile as visual, so let’s peek at the top of each camera.

The X-E4 sports dedicated dials for shutter speed and exposure compensation, a mode dial, and an unlock button - all clustered logically for quick, eyes-off-the-camera adjustments. There's also a function button programmable to your most-used setting, and a hot shoe for external flash units.

The Nikon 1 S1, designed more for point-and-shoot simplicity, lacks a mode dial or customizable buttons. Its shutter speed dial is functional but limited in range. Notably, it includes a small built-in flash, whereas the X-E4 requires an external flash - fine for professionals who often bring their own lighting, less ideal for casual shooters who want quick fill light.

If you value having physical control clubs at your fingertips, the X-E4 feels like it belongs in a photographer’s hands; the Nikon 1 S1 caters to those who prefer simplicity and minimal fuss.

See What You Shoot: Viewfinder and LCD Screen

An electronic viewfinder and screen can make or break your shooting experience, particularly in bright daylight or when tracking moving subjects.

The X-E4 has a 2360k-dot OLED electronic viewfinder with 100% coverage and 0.62x magnification. It’s bright, sharp, and responsive - great for manual focus or compositions in bright environments. The rear is a 3-inch 1620k-dot tilting touchscreen, invaluable for low-angle shots or selfies, plus intuitive menu navigation and focus point selection with your thumb.

Meanwhile, the Nikon 1 S1 skips the EVF entirely, relying on its 3-inch 460k-dot fixed TFT LCD screen with no touch capability. It’s a struggle in daylight, forcing you to crane your neck or guess at exposure. The lack of tilting or articulating screen hampers creative framing.

If you want to feel confident in what you’re capturing, especially outdoors, the Fujifilm X-E4’s display system is completely in a different league.

Autofocus and Continuous Shooting: Catching the Action

Let’s talk eye detection, burst speed, and tracking - crucial for wildlife, sports, and street photography.

The X-E4 boasts a hybrid phase and contrast detection AF system with 425 autofocus points, including face and eye detection for humans, locked-on AF tracking, and decent responsiveness. It can hit a continuous burst rate of 20 fps using the electronic shutter, which is fantastic for fleeting moments like kids’ games or wildlife.

The Nikon 1 S1 has a smaller autofocus area with contrast and phase detection, but its 135 focus points and AF capabilities feel more rudimentary and slower in action. It maxes out at 15 fps, respectable for its time but now edging behind. It lacks eye detection capabilities and doesn't support continuous AF during bursts.

For sports, wildlife, or any fast-moving subjects - the X-E4 will get you more keeper shots with less frustration.

Real-World Photography Across Genres

I’ve put these cameras through suites of genre tests to see beyond specs. Here’s what you can expect:

Portrait Photography

The Fujifilm X-E4 nails flattering skin tones thanks to Fujifilm’s legendary color science and dynamic range. Its APS-C sensor combined with fast prime lenses delivers natural bokeh and beautiful separation. The X-E4’s eye-detection autofocus helps ensure tack-sharp portraits even at wide apertures.

The Nikon 1 S1, by comparison, produces decent portraits only in bright light. Its smaller sensor means depth-of-field control is less pronounced, so background blur and subject separation lack the creamy artistry photographers chase.

Landscape Photography

Thanks to a high-resolution sensor and excellent dynamic range, the X-E4 captures landscapes with exquisite detail in highlights and shadows. Its weather sealing is absent but the robust build lets you shoot cautiously outdoors.

The Nikon 1 S1 struggles here due to lower resolution and smaller dynamic range; fine detail often gets lost, and noise creeps into shadows quickly.

Wildlife and Sports

The X-E4’s fast 20 fps burst and superior AF tracking shine for birds in flight and fast sports. Its lens ecosystem offers telephoto options to close the gap on distant subjects.

The Nikon 1 S1, with fewer lens options and slower AF, is less suited for demanding wildlife or sports shots.

Street and Travel

Surprisingly, the Nikon 1 S1 is appealing here due to its ultra-compact form and light weight, perfect for casual snapshots. The X-E4 is still quite compact but less pocketable.

Macro and Night / Astrophotography

Neither camera has built-in stabilization, but the X-E4 has superior sensor performance in low light. The Nikon’s high ISO noise makes it the weaker choice after sunset.

Video Capabilities

The Fujifilm X-E4 records crisp 4K UHD at 30p with decent bitrate and microphone input for audio - perfect for creators who want better video. Nikon 1 S1 maxes out at 1080p and lacks microphone input, more suited for casual videography.

Lens Ecosystem and Compatibility

The Fujifilm X-mount has flourished with 58 lenses available, ranging from affordable primes to professional zooms and macro lenses. This ecosystem is a huge investment value, offering creativity and technical control.

The Nikon 1 mount’s selection is sparse, with only 13 lenses released before being discontinued. Telephoto and specialty lenses are limited, curtailing growth potential.

Build Quality and Weather Resistance

Neither camera has professional-grade weather sealing. The X-E4 has a sturdier metal chassis that inspires confidence for occasional outdoor use; the Nikon 1 S1 feels plasticky and more vulnerable to rough conditions.

Battery Life and Storage

The Fujifilm X-E4 offers about 380 shots per charge, reasonable for mirrorless but not class-leading - keep a spare battery handy for full-day shooting. The Nikon 1 S1 lags with only 220 shots, reflecting older battery tech and smaller capacity.

Both use standard SD cards, with a single slot - not ideal for professional workflows.

Connectivity and Wireless Features

Modern shooters appreciate wireless convenience: the X-E4 has built-in Wi-Fi and Bluetooth for fast photo transfer and remote camera control via app. The Nikon 1 S1 offers optional wireless via accessories but lacks BT and NFC standard.

Price-to-Performance: Is the X-E4 Worth the Premium Over Nikon 1 S1?

Considering the Fujifilm X-E4 retails around $850, while the Nikon 1 S1 can be found near $230 (used or new old stock), that’s nearly a four-times price difference.

My experience shows the X-E4 justifies this premium thanks to superior sensor tech, AF system, controls, video, and lens support. The Nikon 1 S1 is a budget entry for beginners who want a tiny point-and-shoot alternative and are happy to compromise image quality and handling.
