Sony NEX-3 vs Sony TX10: A Hands-On Comparison for the Discerning Photographer

As cameras continue to evolve rapidly, choosing the right model can be a nuanced decision, especially for photographers seeking the balance between portability, image quality, and ease of use. Today, I share my extensive hands-on experience comparing two seemingly disparate Sony models from the early 2010s: the mirrorless Sony Alpha NEX-3 and the ultracompact Sony Cyber-shot DSC-TX10.

Though these cameras cater to different segments, both garnered attention for packing notable features in their class. With years of personal testing and thousands of images shot, this in-depth head-to-head review will help you understand not only specs on paper but what truly matters in practical photography terms.

Getting to Know the Contenders: Entry-Level Mirrorless vs Ultracompact

Before diving into performance and image quality, it’s important to lay down the basics of who these cameras are designed for.

Sony NEX-3 was one of Sony’s first forays into interchangeable-lens mirrorless cameras targeting beginners craving DSLR-like quality without the bulk. It offers an APS-C sensor typically found in DSLRs and a vast ecosystem of E-mount lenses.

Sony TX10 took a different approach: an ultracompact fixed-lens point-and-shoot, emphasizing grab-and-go convenience. Marketed as a rugged, waterproof compact, it’s aimed at casual users wanting pocketability with some image quality upgrades over typical compacts.

This fundamental difference in design philosophy strongly influences every aspect of their handling, features, and performance - which I'll unpack for you in depth.

Size and Ergonomics: How They Feel in Your Hands

One of the first things you notice testing the NEX-3 and TX10 side-by-side is their physical disparity.

The NEX-3 measures a stout 117 x 62 x 33mm and weighs in at 297 grams (body only). It adopts a rangefinder-style mirrorless body, giving you a comfortable grip and a layout reminiscent of traditional cameras. This makes extended shooting sessions easier on the hands, especially with compatible lenses that balance the body well.

In contrast, the TX10 is remarkably slim – just 96 x 56 x 18mm and 133 grams - almost half the weight of the NEX-3. Its plastic, pebble-shaped chassis fits nicely in a pocket but sacrifices grip comfort and external controls. This compactness is excellent for travel and street photography where discretion and light packing are priorities but offers less tactile feedback.

Furthermore, the NEX-3 has a tilting 3-inch screen (920k dots) that helps when shooting at awkward angles, while the TX10’s 3-inch fixed touchscreen (921k dots) allows intuitive point-and-shoot operation but lacks flexibility in framing.

Control Layout and User Interface: Efficiency Matters

Sony thoughtfully equipped the NEX-3 with a more traditional camera control layout tailored for quick access to key settings.

You’ll find a mode dial with manual, aperture priority, shutter priority, and program options. The dedicated exposure compensation dial and customizable buttons were refreshing for an entry-level camera. This allows seasoned enthusiasts or beginners eager to learn manual exposure to gain confidence quickly.

On the other hand, the TX10, designed for ease of use and compactness, uses a simpler button interface without manual exposure modes or shutter priority options. Instead, it relies heavily on the touchscreen interface, which is responsive but sometimes clunky when trying to adjust quickly in dynamic shooting situations.

I found during extended use that the NEX-3’s dedicated controls allowed swifter adjustments, especially important for evolving light scenarios or creative experimentation. The TX10’s touchscreen is intuitive for novices but less efficient for users wanting fast manual tweaks.

Sensor Size and Image Quality: The Heart of the Matter

Arguably the most significant determinant of photo quality is sensor size and technology. Here the gap is wide.

The Sony NEX-3 boasts a large APS-C CMOS sensor measuring 23.4mm x 15.6mm - approximately 365 square millimeters of sensitive area. This is a major advantage because larger sensors collect more light per pixel, resulting in better detail, dynamic range, and low-light performance. It sports a 14MP resolution, producing images at 4592 x 3056 pixels, an excellent balance of resolution and high ISO noise control.

In contrast, the TX10’s sensor measures just 6.17mm x 4.55mm (1/2.3-inch BSI-CMOS) with an area of 28 square millimeters, just a fraction of the NEX-3’s. Despite packing a slightly higher 16MP resolution, this smaller sensor limits light-gathering ability, resulting in more noise at elevated sensitivities and less dynamic range.

From my testing, the NEX-3 consistently delivers richer colors, smoother gradations, and cleaner high ISO shots up to ISO 12800 native (though noisier at maximum). The TX10 performs admirably in bright conditions but struggles as light dims, with noticeable noise and limited shadow detail.

Rear Display and Viewfinder: Composition Tools Compared

Neither camera includes an electronic viewfinder, so reliance on the rear LCDs is paramount.

The NEX-3’s 3-inch tilting TFT Xtra Fine LCD with 920k dots resolution gave me excellent viewing angles and good brightness under daylight, especially helpful outdoors. The tilting mechanism aids composition from waist level or overhead, useful for creative perspectives.

The TX10 features a 3-inch fixed XtraFine touchscreen with 921k dots – almost identical in resolution but without tilt. The touchscreen’s responsiveness is a plus for quick focusing and menu navigation, yet the fixed angle limited framing flexibility during some shots.

For more serious composition control, neither camera features a built-in viewfinder, which is a notable limitation on bright days or in fast shooting situations, especially on the NEX-3 where focusing can sometimes be challenging without eye-level framing.

Autofocus Performance: Speed and Accuracy Under Pressure

An autofocus system’s responsiveness directly impacts success in fast-paced styles like sports or wildlife.

The Sony NEX-3 uses a 25-point contrast-detection AF system with face detection but lacks phase detection. It supports continuous autofocus during bursts but does not provide advanced tracking or subject recognition like animal eye AF found in modern cameras.

During my testing, the NEX-3’s autofocus is reliable in good light but can hesitate in low-contrast or dim situations, resulting in occasional missed focus – a byproduct of its early mirrorless tech generation.

The TX10 includes a 9-point contrast-detection AF system with touch-to-focus capability. Given its compact design, it sacrifices advanced tracking but benefits from a close-focus macro mode (down to 1cm) excellent for casual close-ups. It does optically stabilize the lens, improving handheld sharpness.

In quick-action shooting, the NEX-3 generally focuses more accurately but slower, while the TX10’s faster but less precise system excels best in straightforward scenes. Neither is ideal for demanding sports or wildlife, but the NEX-3 holds a slight edge in precision.

Burst Shooting and Shutter Speeds: Capturing the Decisive Moment

For capturing motion, continuous shooting speed and shutter range are crucial.

The NEX-3 delivers a solid 7fps burst rate, respectable for its class and era. Maximum shutter speed tops out at 1/4000 sec, accommodating bright daylight shooting with wide apertures.

The TX10 surpasses this with up to 10fps bursts but at a maximum shutter speed of 1/1600 sec. The higher burst rate favors casual action shots but restricted shutter speed limits bright-light creativity.

For sports or wildlife enthusiasts, the NEX-3’s balance of shutter range and burst speed offers more flexibility, though both cameras are somewhat limited compared to dedicated sports cameras.

Lens Ecosystem and Optical Versatility: Expand or Fixed?

One core strength of the Sony NEX-3 is its interchangeable E-mount lens system, with over 121 compatible lenses ranging from primes to zooms, macros, and specialty optics. This variety opens up every photography genre imaginable.

The TX10 has a fixed 25-100mm (35mm equivalent) zoom lens with an aperture range of f/3.5 to f/4.6, providing reasonable flexibility but no option for upgrades. This 4x zoom offers wide-to-telephoto reach, suitable for casual shooting but limiting specialized needs like portraits with wide apertures or macro work.

From lenses alone, the NEX-3 wins hands-down for photographers aiming to develop skills or opt for specific creative results.

Build Quality and Durability: How Tough are These Cameras?

Sony crafted distinctly different builds catering to separate use cases.

The NEX-3 features a plastic body without weather sealing, not designed for rough conditions. While it feels solid for an entry-level mirrorless, it requires extra care in inclement weather or rugged environments.

Conversely, the TX10 is enthusiastically rugged: waterproof, dustproof, shockproof, and freezeproof - perfect for adventure seekers or travel photographers who need a tough companion.

If you often shoot outdoors in challenging situations, the TX10’s waterproof and durable build is a compelling advantage. For controlled environments or studio work, the NEX-3 serves fine but demands more careful handling.

Battery Life and Storage: Longevity in the Field

The NEX-3 uses the Sony NPFW50 battery rated around 330 shots per charge, typical for mirrorless cameras of its time. It supports SD/SDHC/SDXC and Memory Stick formats.

The TX10’s battery life specifics are less clear in specs, but compact cameras in this category generally deliver fewer shots per charge, often around 200-250. Storage options are similar, supporting SD cards and Memory Stick.

If you prioritize longer shooting sessions without frequent battery swaps, the NEX-3 is preferable.

Video Capabilities: Which Handles Motion Better?

The TX10 surprises with full HD (1920 x 1080) video at 60 fps, offering smooth, detailed recordings and supporting common formats including MPEG-4, AVCHD, and H.264.

The NEX-3 tops out at 1280 x 720 HD video at 30 fps, which looks modest by modern standards.

For casual video content or travel vlogging, the TX10’s higher resolution and frame rate deliver better footage, but lack of manual video controls limits the professional potential.
