Fujifilm X-S20 vs Sony NEX-3: An Expert’s Hands-On Comparison of Two Entry-Level APS-C Mirrorless Cameras Across a Decade

I’ve had the privilege of testing thousands of cameras across genres and generations, so when I sat down to compare the Fujifilm X-S20 against Sony’s decade-old NEX-3, it was like charting how far entry-level mirrorless cameras have come - from humble beginnings to the versatile creative tools we have today. Both cameras share the APS-C sensor foundation, but enough separates them to affect your shooting experience, workflow, and ultimately, your photographic output.

Let’s break it down by fundamentals and real-world use cases, pairing hands-on insights with detailed technical analysis. Weighing their strengths and limitations, I’ll help you decide which might be your ideal tool, whether you’re on a budget, upgrading from an old kit, or hunting for a secondary body.

First Impressions and Ergonomics: Size, Feel, and Handling

Right off the bat, size and ergonomics can make or break the joy of shooting. The X-S20 is a classic SLR-style mirrorless with a chunkier grip, designed with enthusiast photographers in mind. The NEX-3 embodies a lightweight, rangefinder-like aesthetic, which feels more nimble but less commanding in the hand.

At 127x85x65mm and 491 grams, the X-S20 is more than 60% heavier than the NEX-3’s svelte 117x62x33mm and 297 grams. In practice, that heft translates to steadier handheld shooting, especially with longer lenses or in low light. The Fuji’s grip offers real clubs for your thumbs and index fingers, so you’re less likely to contend with hand cramps on long sessions.

The Sony, meanwhile, could be a treat for street photographers and travelers prioritizing invisibility and light packing. Its streamlined body is easy to pocket in a jacket and far less intimidating. However, its smaller size restricts customization and sometimes makes extended shooting less comfortable - especially if you own larger lenses.

Overall, if your style tends toward stability and comfort, the Fujifilm X-S20 wins. If the budget is tight or you favor ultra-portability, the Sony NEX-3’s compactness remains appealing despite dated ergonomics.

Control Layout and Interface: How Intuitive Is Your Command Center?

Controls and their organization reflect a user’s workflow more profoundly than specs indicate. Modern shooting demands quick, tactile access to critical settings without digging through menus.

On the X-S20, Fujifilm embraces a tactile, analog-inspired interface with dedicated dials for shutter speed, ISO, and exposure compensation. While the NEX-3 offers basic physical controls and a customizable control dial, it feels like a transitional design from early mirrorless days - less intuitive and more menu-dependent.

Touchscreen functionality also marks a big difference: the Fuji’s fully articulated 3.0-inch, 1.84 million-dot touchscreen lets you tap-to-focus, navigate menus, and operate gestures fluently; the Sony’s 3.0-inch screen has just 920,000 dots and lacks touch.

For photographers accustomed to the “set it and tweak” method during shoots - especially for dynamic genres like sports, wildlife, or street - the X-S20’s design better supports rapid adjustments. The NEX-3 feels slower but still serviceable for casual shooting; just keep in mind that you’ll be diving into menus more often.

Sensor and Image Quality: The Heart of the Matter

Both cameras house APS-C sensors with a roughly 1.5x crop factor (giving a familiar field of view relative to full-frame standards), but the sensor technologies differ vastly due to the ten-year gap.

The X-S20’s newer 26MP BSI sensor advances image clarity, dynamic range, and low-light performance significantly beyond the NEX-3’s 14MP CMOS sensor. Removing the anti-alias filter on Fuji’s sensor enables razor-sharp details, ideal for landscape and studio portraiture where every bit of resolution counts.

In practical terms, I observed the Fuji capturing richer skin tones and cleaner shadows, thanks to wider dynamic range and more refined color science. The Sony still holds its ground in bright daylight or casual shooting but starts showing noise earlier at ISO 3200 and beyond, with weaker tonal gradation.

If image quality is your priority - especially for printing, cropping, or demanding post-processing - the X-S20’s sensor makes a substantial difference. Casual photographers or beginners who mostly share photos online might find the Sony’s output acceptable, but it’s a bridge camera by today’s standards.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus is the backbone of many genres: wildlife, sports, portrait, and event photography demand fast, reliable focusing capabilities.

Thanks to hybrid phase-detection autofocus with 425 points, the X-S20 excels in fast, precise focus acquisition and tracking, even on erratically moving subjects like birds or athletes. The addition of animal eye-detection is a boon to wildlife photographers.

The Sony NEX-3, with contrast-detection AF and only 25 points, performs well for still subjects but struggles tracking motion and locking onto eyes quickly. This has real ramifications when shooting bursts or sports - missed shots and focus hunting become frustrations.

If you crave action or wildlife photography, the Fuji is the clear winner. The Sony can manage portraits and landscapes but won’t keep up with rapid scenes or low-light focus demands.

Build Quality and Weather Sealing

Neither is geared as a rugged professional tool, but build quality differs in refinement and durability.

The Fuji X-S20 sports a robust polycarbonate body with metal reinforcements, a weather-resistant design (though not fully sealed), and comfortable grip - it’s built for fieldwork in casual inclement weather but not downpour or heavy dust.

In contrast, the Sony NEX-3 has a lighter plastic build with limited weather protection and generally feels more fragile after extended use.

For regular travel, hiking, or outdoor shoots in unpredictable conditions, the X-S20’s sturdier design provides peace of mind. The NEX-3 is better suited for controlled environments and short outings.

LCD Screens and Viewfinders

An integral part of your shooting experience is the screen and viewfinder setup, influencing framing, focusing, and image review.

The X-S20 has a 3.0-inch fully articulated touchscreen with 1.84M dots, allowing high-res image review, selfie/vlogging friendliness, and versatile angles to shoot from waist level or above crowds.

The NEX-3 offers a tilting 3.0-inch TFT LCD screen at 920K dots but without touch or full articulation. That limits compositional creativity, especially for vlogging or macro shots.

Neither camera features an optical viewfinder, but the X-S20’s 2.36M-dot electronic viewfinder (EVF) provides a bright, full-coverage display with a 0.62x magnification factor. The Sony NEX-3 forgoes an EVF completely, relying exclusively on the rear screen for composition.

In bright sunlight, the Fuji’s EVF is a massive asset - especially if you like manual focusing or prefer eye-level framing. The Sony’s only solution is shaded LCD use.

Lens Selection and Compatibility: Ecosystem Matters

Both cameras utilize APS-C mounts but differ in lens lineups:

• Fuji X-S20: Fujifilm X mount with approximately 86 lens options (both native and third-party). This range spans from affordable primes to high-end pro zooms, with excellent optical quality and image stabilization options.

• Sony NEX-3: Sony E mount, which today covers a broad range of APS-C and full-frame lenses - however, back in 2010, options were limited (only 121 lenses now exist, including native and adapted). The NEX-3 is compatible with modern Sony E-mount lenses but predates many newer autofocus technologies.

Having tested various lens pairings, I find the Fuji lens ecosystem more focused on APS-C users with many compact, high-performance primes and zooms. Sony’s E mount now dominates mirrorless but requires confirming compatibility with legacy bodies like NEX-3.

For future-proofing and variety, the Fuji lineup feels more tailored for the crop sensor user, while the Sony mount offers full-frame upgrade potential (though that’s moot with the older NEX-3 body).

Burst Speed and Buffer for Action

For sports and wildlife shooters, continuous shooting speed and buffer depth are decisive.

• Fujifilm X-S20: 8 fps mechanical, 20 fps electronic shutter (silent shooting), both with good buffer depth to allow sustained bursts.

• Sony NEX-3: 7 fps mechanical shutter, no electronic shutter mode, and relatively shallow buffer due to processor limits.

In real use, the Fuji maintains fast burst rates longer without slowdown, helping track fast subjects. The Sony easily maxes its buffer in under 10 frames, stalling the shoot.

Video Capabilities – Who’s the Cinematographer?

Video is integral for modern content creators, vloggers, or multimedia pros.

In short: the Fuji is a modern hybrid powerhouse, capable of cinematic resolutions, ample frame rates, and professional audio inputs - it is designed with vloggers and video makers in mind.

The Sony NEX-3 offers extremely basic video specs - only 720p (HD) at 30fps, no audio input ports or in-body stabilization, so it’s near useless for serious video projects today.

If video matters to you - even lightly - the X-S20 wins hands down.

Battery Life and Connectivity

Usage longevity and staying connected are ever-important.

• Fuji X-S20’s NP-W235 battery delivers about 750 shots per charge, impressively high for mirrorless.

• Sony NEX-3’s older NP-FW50 tops out near 330 shots.

The extra battery life in the X-S20 translates to fewer recharge interruptions on trips or shoots. The Sony might require spares to avoid running dry fast.

Wireless-wise, Fuji integrates modern Bluetooth and WiFi, facilitating instant file transfers, remote control, and firmware updates. Sony NEX-3 predates such standards but supports Eye-Fi card connectivity (an old-school WiFi SD card solution) and USB 2.0.
