Fujifilm X-A3 vs Sony NEX-3: An Expert Comparison for Discerning Photographers

In my experience testing hundreds of entry-level mirrorless cameras over the past 15 years, the mid-2010s era represented a critical pivot point. Brands like Fujifilm and Sony boldly redefined how affordable mirrorless cameras could serve both newer users and enthusiasts stepping deeper into photography. Today, I’m diving into a detailed, hands-on comparison between two notable contenders from that era: the Fujifilm X-A3, announced in August 2016, and the Sony NEX-3, unveiled back in June 2010. Despite their differences in release date and technology generation, they still attract interest from photographers hunting either a beginner’s camera or a secondary, compact shooter.

In this thorough review, I’ll cover all major aspects - from sensor and autofocus tech to ergonomics and genre suitability - based on my direct testing sessions with both. Along the way, you’ll find practical insights, objective technical analysis, and candid opinions that only long-term experience can yield. Let’s get right into the heart of the matter.

Size and Ergonomics: Who’s Made for Holding?

Beginner photographers often overlook ergonomics, yet it’s a cornerstone of practical usability. After all, a camera must feel pleasant in the hand when you’re out in the field, not just look good on paper.

Both cameras adopt a classic mirrorless rangefinder-style body, but the Fujifilm X-A3 has grown slightly thicker and taller to incorporate its more modern components. Weighing 339 grams and measuring 117 x 67 x 40 mm, the X-A3 feels a bit more substantial and solid in hand than the Sony NEX-3, which weighs 297 grams and measures 117 x 62 x 33 mm.

This difference is immediately noticeable:

The Fujifilm’s slightly chunkier grip, sculpted gently on the right side, provides a more confident hold, especially for users with larger hands or those planning prolonged shooting sessions. Sony’s NEX-3, meanwhile, is more compact and carries a slimmer profile, which may appeal to minimalist packers or street photographers favoring discretion.

However, the trade-off is that the Sony’s smaller size sometimes makes manual adjustments feel fiddly, especially for photographers who like tactile feedback and robust controls.

In real-world usage, I found the Fujifilm's grip far more rewarding for a sustained shoot, especially when paired with heavier lenses. If size and feel top your priority - particularly for travel or outdoor shooting - the X-A3 edges ahead.

Control Layout and Interface: Intuitive or Overwhelming?

User interface impacts how quickly photographers can access what they need - important in dynamic environments like events or wildlife.

Both cameras forgo electronic viewfinders, so you rely on LCD screens and physical controls. The Fujifilm X-A3 features a modern design refinement: several intuitive buttons, an informed menu system, and a tilting 3-inch touchscreen with 1,040k-dot resolution, whereas the Sony NEX-3 sticks to a traditional button and dial combo alongside a non-touch tilting 3-inch LCD with 920k-dot resolution.

Here’s a look at their control tops:

The Fujifilm’s dedicated dials for exposure compensation and drive modes give it an advantage for photographers who want quick on-the-fly adjustments without digging into menus. Meanwhile, the Sony NEX-3’s control surface feels a bit bare - ideal for newcomers overwhelmed by too many buttons but somewhat limited when you want rapid tweaking during intense shooting.

The touchscreen on the X-A3 makes focusing and menu navigation fast and natural. Its touchscreen live autofocus is especially handy for portraiture. The Sony’s lack of touchscreen means fumbling through physical buttons, which can slow you down.

Ergonomically and interface-wise, Fujifilm’s X-A3 feels like a better tool for photographers who want to learn fast but don’t want to be held back by the controls.

Sensor and Image Quality: Resolution and Dynamic Range

Both cameras sport an APS-C sized CMOS sensor with a 1.5x crop factor. Let’s talk about what that really means for your photography.

The Fujifilm X-A3 integrates a 24MP sensor with a Bayer color filter array and EXR Processor II, placing it in a more modern league concerning resolution and color fidelity. Interestingly, Fujifilm sticks with an anti-aliasing filter, which slightly tempers sharpness but reduces moiré in fine textures - a pragmatic choice balancing clarity and image integrity.

The Sony NEX-3 has a 14MP sensor, also APS-C but with older CMOS tech driven by the Bionz processor, common in early mirrorless cameras. While 14MP is adequate for moderate cropping and online sharing, it struggles to offer the same detail for large prints or heavy post-processing.

Neither camera is tested on DxOMark (for the Fujifilm) or fairly dated sensor scores on the Sony showing an overall score of 68, color depth 22.1, and dynamic range 12.0, which was competitive at the time but clearly behind more recent sensors.

Pragmatically, I found the X-A3 delivers richer skin tones - essential for portraits - and better dynamic range that retains highlight and shadow detail in landscapes and street scenes. The Sony sensor’s lower resolution is more noticeable under pixel-peeping, and the dynamic range hampers recoverability in challenging high contrast lighting.

If you prioritize image fidelity, larger prints, or cropping flexibility, the Fujifilm’s sensor is a clear winner here.

Rear Screen and Viewfinder: Composing and Reviewing Images

Neither camera includes an electronic viewfinder, which isn’t uncommon at this price point and era. That puts extra importance on the LCD screen.

The Fujifilm X-A3 boasts a higher resolution tilting touchscreen (1040k dots) compared to Sony’s 920k-dot TFT with no touch interface.

During field tests, Fujifilm’s screen showed crisper, more vibrant images, and the touchscreen allowed easy face and eye autofocus selection - a godsend when shooting portraits or moving subjects. Sony’s screen, while clear and adequately bright, lacked the responsiveness and detail the X-A3 offers.

The tilting mechanism on both is similar, allowing easier selfies or low/high angle compositions, but the touchscreen adds tangible workflow speed.

If you spend much time shooting without a viewfinder, the X-A3’s LCD advantages improve your shooting pace and framing confidence.

Autofocus Performance: Speed, Accuracy, and Tracking

AF capability defines how well a camera handles anything from portraits to sports.

The Fujifilm X-A3 includes a contrast-detection based system with 77 focus points and eye detection AF, notable for its time and category. It even features continuous AF for video, a plus for casual videographers.

In contrast, the Sony NEX-3 employs a similar contrast-based AF system with 25 points but no eye detection or AF tracking capability. It has continuous AF, but tracking moving subjects reliably is tricky.

Through extensive real-world testing, especially following fast-moving subjects during outdoor walks and street shooting, the X-A3’s AF felt markedly quicker to lock focus and more reliable in maintaining it amid face and eye detection. Sony’s AF occasionally hunts longer and hesitates when lighting gets tougher or subjects move erratically.

Continuous AF on the X-A3 also sustained smoother transitions in video capture, while the NEX-3’s continuous AF was more jumpy.

For wildlife, sports, or any action photography, I’d put my money on the Fujifilm’s more evolved AF system for this pair.

Burst Shooting and Shutter Speed: Catching the Moment

Continuous shooting allows photographers to seize fleeting moments, particularly in sports or wildlife.

Sony NEX-3 can shoot up to 7 frames per second (fps) at 14MP, while Fujifilm X-A3 offers 6 fps at 24MP.

Though the Sony is fractionally faster, it shoots fewer megapixels, which impacts post-crop flexibility.

Regarding shutter speed ranges, both offer a minimum mechanical shutter speed of 30s up to 1/4000s. The Fujifilm enhances this with an additional electronic shutter mode up to 1/32000s, perfect for bright conditions or wide apertures without ND filters. The Sony lacks this feature.

This electronic shutter gives Fujifilm an edge for creative expression and convenience outdoors - something I missed when shooting the Sony under bright skies.

For sports or wildlife, Sony’s 7 fps is appealing but offset by Fujifilm’s higher resolution and versatile shutter options.

Lens Ecosystem and Compatibility: Growth and Flexibility

Lens availability often dictates a system’s long-term value.

Fujifilm’s proprietary X-mount lineup counts 54 lenses spanning from fast primes for portraits to versatile zooms for travel and wildlife. These lenses are generally acclaimed for optical quality and build. Fuji’s system also enjoys extensive third-party support from brands like Viltrox and Samyang, solidifying its appeal for future-proofing.

Sony’s E-mount system started with the NEX line, accumulating to over 121 lenses in the category including APS-C and full-frame options - a wider catalog benefiting from Sony’s ongoing mirrorless leadership.

However, when the NEX-3 launched in 2010, native lens choices were fewer and early lenses lacked advanced features like fast stepping motors for video.

While Sony’s lens selection is broader now, early NEX users may struggle with native lenses that complement the older sensor well. Plus, some lenses made for later generations perform better on newer bodies.

For entry-level users seeking solid native glass built to optimized APS-C specs, the Fujifilm X-A3 system may feel more cohesive. Sony’s flexibility leans toward users willing to invest heavily or upgrade bodies for full-frame.

Build Quality and Weather Resistance: Durability in the Real World

Neither camera offers weather sealing - a common omission for cameras targeting beginners or budget buyers.

Fujifilm X-A3 features a sturdy plastic and metal composite chassis, feeling surprisingly tough and resistant to everyday knocks. Sony’s NEX-3 uses a lightweight plastic shell, less rigid under stress.

Neither should be your first choice if persistent rain, dust, or rough handling are expected, though Fujifilm’s build inspires more confidence overall for casual outdoor shooting.

Battery Life and Storage Options: Staying Powered on Shoots

Battery endurance can make or break a day in the field.

The Fujifilm X-A3 uses the NP-W126S battery, rated for about 410 shots per charge (CIPA standard). The Sony NEX-3’s older NP-FW50 battery provides about 330 shots.

In typical shoot scenarios mixing stills and sporadic video, I found the Fujifilm lasts about 25% longer. That’s meaningful when shooting travel or multi-hour events where power outlets aren’t available.

Both cameras use a single SD card slot, but the Sony uniquely supports Memory Stick Pro Duo formats, a legacy holdover that’s less convenient today.

Connectivity and Wireless Features: Sharing and Control

In 2016, the Fujifilm X-A3 introduced built-in wireless connectivity for image transfer and remote control via smartphone apps - improving the casual and social sharing experience.

Sony’s NEX-3, coming from 2010, lacks integrated Wi-Fi but supports Eye-Fi cards for wireless transfer, an older and more cumbersome method.

Also note, neither camera offers Bluetooth or NFC, so wireless options are limited compared to modern models. Still, Fujifilm’s solution is more seamless and user-friendly.

Video Capabilities: Moving Images Worth Capturing

Neither camera targets heavy videography, but entry-level hybrid users will want some flair.

The Fujifilm X-A3 records Full HD 1080p video up to 60p in MPEG-4/H.264, with continuous autofocus and IS support provided by optical lenses (no in-body stabilization).

The NEX-3 caps out at 720p HD at 30fps, using MPEG-4. AF is contrast-based and less smooth for video.

No microphones or headphone jacks exist on either, limiting external audio options.

In practical use, the Fuji’s Full HD video performance is significantly better suited for casual filmmaking or vlogging, with smoother focus transitions and sharper output.
