When navigating entry-level mirrorless cameras, especially models launched nearly a decade apart, it’s crucial to dissect every important aspect - from sensor technology to ergonomics and real-world usability - to arrive at informed decisions that truly serve your photography needs. Today, I’m putting two well-regarded cameras head-to-head: Fujifilm’s X-T20, announced in early 2017 as a worthy successor to the X-T10, and Sony’s NEX-3, Sony’s entry-level mirrorless pioneer from 2010, subsequently replaced by the NEX-C3. Both have contributed significantly to the mirrorless market evolution, but how do they compare technically, practically, and aesthetically? Through exhaustive hands-on testing, technical evaluation, and direct performance comparisons, this article aims to serve photographers ranging from hobbyists seeking their first serious camera, to professionals looking for pocketable backups or specialty tools.

Handling and Physical Design: Tactile Experience Meets Portability

The moment you pick a camera up, your interaction begins not only with buttons and dials but also with the body’s dimensions, weight, and control intuitiveness. The Fujifilm X-T20 follows a traditional SLR-style mirrorless body design, inspired by classic rangefinders but loaded with modern controls and ergonomics. Meanwhile, the Sony NEX-3 adopts a compact, rangefinder-style compact shell emphasizing portability.

• Size & Weight: The X-T20 measures 118x83x41 mm, weighing approximately 383g with battery - noticeably larger and heftier than the NEX-3’s 117x62x33 mm and 297g body. For photographers prioritizing ultralight travel setups, NEX-3’s smaller footprint is an attractive attribute, although the X-T20 remains comfortably pocketable in larger coat pockets or camera bags.

• Ergonomics & Grip: The deeper body of the X-T20 offers a pronounced front grip, enhancing stability during prolonged shooting sessions, especially with longer lenses. In contrast, the NEX-3’s minimal grip can feel less secure in one hand, potentially increasing handling fatigue or instability with telephoto lenses - an important consideration for wildlife or sports shooters.

• Control Layout: The X-T20 features dedicated dials for shutter speed, exposure compensation, and ISO, combined with a touchscreen LCD that supports intuitive tap-to-focus. This blend of tactile and touch inputs allows quick adjustments without delving into menus. On the other hand, NEX-3 lacks a touchscreen and relies on more traditional button-and-dial combinations, which feels dated by current standards.

From a subjective standpoint backed by testing dozens of mirrorless cameras, I find the X-T20’s design philosophy caters well to photographers desiring instant manual control - great for nuanced exposure adjustments. The NEX-3, while functional, reflects older design paradigms less intuitive to users acclimatized to newer camera UIs.

Sensor and Image Quality: Hits and Misses Across the Decade

One of the most fundamental differentiators between these two cameras lies in sensor technology. The Fujifilm X-T20 employs a 24.2MP APS-C X-Trans CMOS III sensor without an optical low-pass (anti-aliasing) filter, while the Sony NEX-3 sports a 14.2MP APS-C CMOS sensor with a traditional Bayer color filter array and an optical low-pass filter.

• Resolution: With a 24MP advantage, the X-T20 delivers more detailed files, a boon for landscape or portrait photographers requiring cropping flexibility or large prints. The NEX-3’s 14MP resolution was solid in its era but now feels modest, particularly for pixel-peeping professionals.

• Color Rendition & Filter Design: Fujifilm’s unique X-Trans sensor yields nuanced color reproduction, especially skin tones in portraiture, through its non-regular RGB filter design that suppresses moiré without the softness of anti-alias filters. The NEX-3’s Bayer sensor offers more traditional color output but with slightly less natural skin tone tonality and occasionally harsher digital artifacts at high ISOs.

• ISO Performance & Dynamic Range: The X-T20’s native ISO range maxes at 12800 (boostable to 51200), supported by the robust X-Processor Pro2, providing clean images with good noise control up to ISO 6400 or even 12800 for web use. Sony’s NEX-3 maxes out at ISO 12800 but lacks extended boosts. Real-world results demonstrate the NEX-3’s higher noise levels above ISO 1600, limiting its usability for low-light or night photographers.

• Detail & Sharpness: The absence of an AA filter on the X-T20 allows for crisper details and more faithful texture rendering - advantages easily appreciated in landscape and macro photography. The NEX-3’s AA filter, while limiting moiré artifacts modestly, results in somewhat smoothened micro-detail textures by comparison.

In sum, the X-T20’s sensor architecture and associated processing engine support significantly superior image quality by today’s standards, standing up well in demanding shooting scenarios and large format printing.

User Interface and Display: Interaction and Visualization

The shooting workflow heavily depends on the camera’s display, viewfinder, and user interface quality - affecting both framing precision and ease of operation.

• Rear LCD: Both cameras feature 3-inch tilting LCDs with 920k dot resolution - a surprising parity in clarity given their era difference. However, the X-T20’s display includes touchscreen functionality, enhancing menu navigation, focus point selection, and image playback gestures; the NEX-3’s LCD remains non-touch, necessitating physical button navigation.

• Viewfinder: This is a major gap - X-T20 offers a 2.36M-dot electronic viewfinder (EVF) covering 100% frame with 0.62x magnification. The NEX-3 lacks any EVF, depending solely on the rear screen for composition, which can handicap shooting under bright sunlight.

Having a high-res EVF provides critical real-time exposure, focus peaking, and image preview advantages - vital for outdoor, street, and professional use where precise framing matters. The NEX-3’s omission limits such capabilities.

Autofocus Systems: Precision Meets Speed

Autofocus performance significantly influences the final image, especially when photographing dynamic subjects or needing speed and accuracy.

• Fujifilm X-T20: Incorporates a hybrid autofocus system combining 325 phase-detection points with contrast AF. This abundant dense AF coverage ensures swift subject acquisition and tracking for stills and video. Additional features include face detection and customizable AF modes (single, continuous, tracking) enhancing flexibility.

• Sony NEX-3: Utilizes contrast-detection autofocus only, with 25 AF points. This restricts autofocus speed and tracking capabilities. Face detection exists but continuous AF tracking is limited - problematic for fast action or wildlife.

Testing under daylight and low-light confirms the X-T20’s AF achieves faster lock times and higher hit rates in tracking runners or animals - a critical advantage for sports and wildlife shooting genres. The NEX-3’s AF suits still life, portraits, and controlled environments better where slower AF is acceptable.

Burst Speed and Continuous Shooting

Continuous shooting rates determine how many frames per second (fps) you can capture, affecting your capability to seize fleeting moments in sports or wildlife.

• X-T20: Offers a burst rate of up to 14 fps with mechanical shutter, an impressive figure for its class, allowing comprehensive action capture sequences. Electronic shutter speeds extend up to a remarkable 1/32000s, although burst frame rates with electronic shutter not specified.

• NEX-3: Maxes out at 7 fps burst shooting, adequate for casual sports or wildlife but limiting for very fast subjects.

The difference in burst rates strongly favors the X-T20 for action photography, where subdividing decisive moments into multiple shots is essential for success.

Lens Ecosystem and Compatibility

A camera’s value often hinges on the lenses available - variety, quality, and price.

• Fujifilm X system: Boasts an extensive lineup of 54 lenses, including prime, zoom, macro, and specialized lenses, many renowned for optical excellence and build quality. Native autofocus lens options cover wide-angle to telephoto, catering comprehensively to portraits, landscapes, sports, and macro work.

• Sony E-mount: Even at the NEX-3’s launch, offered 121 lenses, covering an impressive range, yet many early options were bulkier, and some were designed primarily for full-frame E-mount bodies released later. Today’s E-mount lens ecosystem has expanded to include many affordable third-party lenses; however, back in the NEX-3 era, choices were more limited.

For photographers prioritizing lens versatility and system longevity, the Fuji X-mount balances classic optical quality with a focused APS-C system approach. Sony’s E-mount promises more breadth overall, especially today, but early NEX-3 users found options more limited and sometimes costly.

Build Quality and Weather Sealing

Entry-level cameras often economize on durability, but robustness still impacts reliability in challenging environments.

• X-T20: Offers a solid magnesium alloy body shell combined with high-quality plastic elements and a ceramic shutter, delivering moderate weather resistance - not fully sealed, but reliable in light rain or dusty settings.

• NEX-3: Features a predominantly plastic construction without weather sealing; it’s lighter but more vulnerable to wear and environmental hazards.

Therefore, Fujifilm’s approach favors users expecting more rugged handling outdoors, particularly for landscape, travel, or wildlife photography that demands flexibility in all conditions.

Battery Life and Storage Considerations

• Battery: Fujifilm X-T20 uses NP-W126S rated for approximately 350 shots per charge, marginally outperforming Sony’s NPFW50 battery which manages around 330 shots per charge in the NEX-3. For real-world use, these numbers are reasonable but users shooting extensively (wildlife, sports, events) would benefit from carrying spares.

• Storage: Both cameras accept SD/SDHC/SDXC cards; however, the X-T20 supports UHS-II speeds, improving buffer clearance during high-speed bursts and video recording, a noticeable advantage over the NEX-3’s older UHS-I compatibility.

Video Capabilities: Flexibility and Limitations

For users interested equally in stills and video, this comparison offers notable differences.

• Fujifilm X-T20: Delivers 4K UHD recording at 30p/25p/24p with H.264 codec, plus 1080p up to 60 fps, including microphone input for better audio quality recording. Although lacking in-body stabilization, the combination of high-quality sensor and lens stabilization (if present) yields solid footage. Touchscreen focus assists smooth manual pulling.

• Sony NEX-3: Records videos up to 720p (1280x720) at 30 fps, with no microphone or headphone jacks, limiting creative and monitoring potential. To put this plainly, video quality is dated and feature-minimal compared to market standards several generations newer.

Video enthusiasts clearly gain more value with the X-T20’s support for modern codecs, resolutions, and audio options.
