Sony NEX-3 vs. Sony Cyber-shot WX5: A Hands-On Comparison for Discerning Photographers

Choosing your next camera can sometimes feel like decoding a complex puzzle. You want something that balances performance, handling, image quality… all without breaking the bank or saddling you with features you won’t use. Today, I’m diving into a detailed, experience-based comparison of two early-2010 Sony releases - the Sony NEX-3, an entry-level mirrorless camera, and the Sony Cyber-shot WX5, a compact point-and-shoot. Both bring Sony’s renowned imaging expertise to the table but cater to strikingly different audiences and photographic ambitions.

Having personally tested thousands of cameras over the past 15 years, I’ll walk you through how these two cameras stack up, highlighting where each shines or falls short across photography genres, technical performance, and practical use cases. Grab your favorite lens or pack your bag as we explore where the NEX-3 and WX5 fit within your photographic journey.

Size and Ergonomics: How Much Does Portability Matter?

The first thing you notice when handling these two cameras is their vastly different physical footprint and ergonomics. The Sony NEX-3, designed as a rangefinder-style mirrorless system, features a notably larger body, offering room for interchangeable lenses and serious handling comfort. The WX5, meanwhile, is a diminutive compact - truly pocket-friendly, perfect for carry-everywhere scenarios.

The NEX-3 measures about 117mm wide by 62mm high and 33mm deep, weighing in at approximately 297 grams without a lens. Its grip and control placement make it comfortable for extended shoots, especially if you prefer manual controls. Conversely, the WX5 is a nimble 92x52x22mm and just 146 grams - ideal for slipping into a jacket pocket or purse.

If you prize handling and optical versatility, the NEX-3’s larger build is justified. But for casual shooters or street photographers who hate bulk, the WX5 wins on discretion.

Control Layout and Interface: Where Simplicity Meets Customization

Ergonomics continue when we look at button placement and user interface. The NEX-3 features a top-control dial and several customizable buttons, even though it doesn’t boast a top LCD panel. Its buttons provide quick access to frequently used functions like exposure compensation, ISO, and drive modes - crucial for faster workflows.

The WX5 adopts a simpler layout consistent with typical compacts: fewer buttons, no manual exposure modes, and a reliance on menus for settings. This suits beginners or casual users who want to shoot without fuss but can frustrate experienced photographers wanting immediate manual control.

Both cameras use Sony’s Bionz processor for image handling, but only the NEX-3 offers full manual exposure modes – aperture priority, shutter priority, and manual - giving you creative flexibility.

Sensor Technology and Image Quality: The Heart of the Matter

Let’s compare the sensory organs that capture your vision: the sensors and image processors.

The NEX-3’s sensor is a 14MP APS-C CMOS unit measuring 23.4 x 15.6mm - quite sizable for its time, yielding substantial image quality gains, especially in dynamic range and low-light sensitivity. Its sensor area is 365.04 mm², which allows better light gathering than smaller-sensor cameras.

By contrast, the WX5 sports a much smaller 1/2.3-inch BSI-CMOS sensor at 6.17 x 4.55 mm (28.07 mm²) with a 12MP resolution. While the WX5 benefits from back-side illumination to improve sensitivity relative to its size, it physically can’t match the NEX-3 in raw image quality metrics.

DxOMark scores reflect this too: the NEX-3 earns a solid 68 overall with excellent color depth (22.1 bits) and dynamic range (12 stops). The WX5 hasn’t been formally tested, but based on sensor size and ISO limits, expect significantly less latitude and more noise at higher ISOs.

In practical terms, the NEX-3 captures cleaner, richer images with a more natural tonal gradation, while the WX5 struggles in challenging lighting and delivers more compact, albeit less detailed files.

Viewing and Composing: Screen and Viewfinder Experiences

Neither camera includes an electronic viewfinder, which may steer some users towards the NEX-C3 or other successors if EVF is important. So how do they stack up on LCD usability?

The NEX-3 sports a 3-inch tilting TFT Xtra Fine LCD with a resolution of 920k dots - exceptionally sharp and flexible for composing at awkward angles. This tilting screen’s utility becomes immediately apparent in macro or low-angle shots.

The WX5 has a smaller, fixed 2.8-inch screen at a lower resolution (461k dots), which feels dated by today’s standards. It’s adequate for quick framing but lacks the tilt mechanism and finesse required for more thoughtful composition.

Lens Ecosystem and Flexibility: Creativity Unleashed with Interchangeables

One critical advantage of the NEX-3 is its Sony E-mount compatibility, granting access to over 120 lenses – from fast primes to telephoto zooms and specialized glass.

The WX5, by comparison, sports a non-interchangeable 24-120mm equivalent lens (f/2.4-5.9) with a respectable macro focus distance of 5cm. While versatile for general photography, you’re locked into this configuration - no swaps or upgrades.

For photographers wanting to deliberately shape their images - especially portraitists craving creamy bokeh or landscape shooters chasing edge-to-edge sharpness - the NEX-3 opens vastly more doors.

Autofocus Performance: Speed Versus Simplicity

The NEX-3 uses a contrast-detection autofocus system with 25 focus points, face detection, and continuous autofocus options. Though not as lightning-fast as modern hybrid AF systems, it remains responsive in varied conditions and outperforms typical compacts for tracking moving subjects.

The WX5 features just 9 autofocus points, contrast detection only, with limited tracking ability. It supports continuous autofocus but lacks face detection, making it less adept at locking onto complex scenes or fast-moving subjects.

While neither camera is tailor-made for sports or wildlife photography, the NEX-3’s autofocus performance is significantly more capable for action or unpredictable subjects.

Burst Shooting and Shutter Speeds: Capturing the Decisive Moment

In continuous shooting, the WX5 offers a speedier burst at 10 frames per second (albeit with a more modest buffer), whereas the NEX-3 clocks 7 frames per second. Interestingly, the NEX-3’s superior sensor and image processing handle raw files during burst mode, which is a boon if you want editable flexibility.

Shutter speed ranges comfortably meet most shooting needs on both cameras: 30s to 1/4000s on the NEX-3 and 2s to 1/1600s on the WX5. The broader shutter availability on the NEX-3 again points to its professional-oriented controls.

Build Quality and Durability: What to Expect Long-Term

Neither camera offers official weather sealing - no surprises there given their price points and release era. Build feels solid for the NEX-3, with a robust plastic chassis and thoughtful button feedback. The WX5’s plastic compact body feels lighter and less substantial but fits its usage profile as a travel-friendly snapshotper.

Battery Life and Storage: How Long Can You Shoot?

The NEX-3 accommodates the NP-FW50 battery, rated for 330 shots per charge - decent but slightly modest given the body size. With extra batteries, it serves well for extended outings.

The WX5 uses the NP-BN1 battery, but official endurance numbers aren’t specified. Based on its class, expect around 200–250 shots per charge.

Both cameras handle SD and Memory Stick formats, but only the NEX-3 supports SDXC, enabling larger, faster storage options. Dual card slots? No. Storage is a single slot on each.

Image Stabilization: Essential for Sharper Shots?

The WX5 includes optical image stabilization (Sony’s Optical SteadyShot), which helps steady the small-sensor compact’s lens during handheld low-light or telephoto shots.

By contrast, the NEX-3 lacks in-body stabilization but relies on stabilized lenses in the E-mount ecosystem. Given the options, the combination of stabilized glass plus a larger sensor produces superior handheld shots.

Video Capabilities: Beyond Stills

The WX5 surprises with full HD video recording at 1920x1080 50fps in AVCHD format, providing smoother motion and better compression quality typical of early HD compacts. It also supports 1440x1080 and 1280x720 resolutions.

The NEX-3, however, tops out at 720p 30fps MPEG-4 video, reflecting its early mirrorless design limitations. For videographers, the WX5 offers a more compelling video package, though neither camera has microphone or headphone jacks for pro-level audio.

Genre-Specific Performance: Choosing Your Strengths

Let’s break down how each camera performs across popular photography genres, supported by practical experience and technical specs.

Portrait Photography: The NEX-3’s APS-C sensor delivers richer skin tones, nuanced color gradation, and excellent bokeh potential with fast primes. Its face detection autofocus assists eye catching, even if no animal eye AF is present. The WX5’s compact sensor limits depth-of-field control and image quality, resulting in flatter portraits.

Landscape Photography: Dynamic range and resolution are king here. At 14MP and 12 stops of DR, the NEX-3 captures expansive detail in highlights and shadows. Add access to wide, sharp lenses and you have a solid field shooter. The WX5’s smaller sensor and limited ISO range restrict creative latitude outdoors.

Wildlife and Sports: Autofocus tracking is a delicate dance here. The NEX-3’s 25-point AF and continuous AF modes outperform the WX5’s 9-point system, although neither matches flagship systems. Faster burst rate on WX5 is attractive but overshadowed by AF limitations.

Street Photography: Here, the WX5’s size and pocketability shine. Its quiet operation and instant readiness make it a natural for candid street capture. The NEX-3 is less discreet, but better image quality justifies the trade if you prefer manual controls and lenses.

Macro Photography: With the WX5’s close focus down to 5cm and built-in stabilization, you can nail everyday macro shots. The NEX-3 depends on dedicated macro lenses but gains tilting screen advantage for composing tight frames.

Night and Astro Photography: The NEX-3’s higher max ISO (12800 native) and broader shutter range make it better suited for low-light and night work. WX5’s high noise and limited shutter cutoff at 1/1600s hinder such use cases.

Video Use: WX5 offers superior full HD options; NEX-3 lags with only HD 720p. Lack of microphone inputs on both hampers professional workflow.

Travel Photography: Both cameras have merits - WX5 for sheer portability and seamless video; NEX-3 for creative flexibility and image quality. Battery life is roughly comparable but consider bringing spare AAAs or power banks for the NEX.
