Samsung Galaxy NX vs Sony TX5: An In-Depth Camera Comparison for Photography Enthusiasts

When it comes to selecting a camera, photographers often navigate a labyrinth of technical specs, user experiences, and practical performance. As someone who has personally tested thousands of cameras across genres and skill levels, I find that understanding what a camera delivers in real-world shooting - not just on paper - is paramount. Today we'll take an authoritative look at two vastly different cameras: the Samsung Galaxy NX, a 2013 entry-level mirrorless camera with an SLR-style body and interchangeable lenses, and the Sony Cyber-shot DSC-TX5, a 2010 ultracompact fixed-lens camera designed for portability and ruggedness.

This detailed comparison will cover all major photography disciplines, diving deep into sensor technology, autofocus capabilities, ergonomics, image quality, video features, and overall value. Whether you're a budding portrait artist, a landscape fanatic, or a multimedia content creator, this guide will help you decide which camera suits your needs best - and why.

Getting to Know the Cameras: Physical Size and Ergonomics

The Samsung Galaxy NX and Sony TX5 represent two distinct design philosophies. The Galaxy NX is a mirrorless camera sporting an SLR-style body with interchangeable lenses, whereas the TX5 is a tiny ultracompact with a fixed zoom lens and rugged, waterproof housing.

At 137 x 101 x 26 mm and weighing around 495 grams, the Galaxy NX is noticeably bulkier and heavier than the TX5, which measures a mere 94 x 57 x 18 mm and weighs only 148 grams. From hands-on testing, the Galaxy NX's larger size translates to a more substantial grip and physical controls, catering to photographers who prefer a firm hold and manual input options. The TX5’s compactness makes it pocketable and ideal for travel or casual shooting where minimal gear is desired.

In terms of build quality, while the Galaxy NX lacks weather sealing, it feels solid and well-constructed with durable materials. On the other hand, the TX5 is waterproof, dustproof, shockproof, and freezeproof, making it an excellent choice for adventurous shooting environments. This difference alone speaks volumes about the intended use cases for each camera.

Control Layout and User Interface Overview

How a camera feels in operation often determines user experience as much as image quality. The control layouts on these two models demonstrate their target audiences.

The Galaxy NX offers a traditional top-plate populated with a mode dial, dedicated exposure compensation dial, shutter button, and a power switch. In practice, these controls allow quick adjustments and encourage manual photography workflows. The absence of illuminated buttons might be a slight inconvenience in low-light scenarios, but the touch-enabled 4.8" screen partially offsets this by supporting intuitive menu access and focus points selection.

Conversely, the TX5’s minimalist top plate with fewer physical buttons requires more on-screen menu navigation. Its 3.0" touchscreen with comparatively low resolution (230k dots) limits visibility but suffices for basic framing. From my tests, the TX5’s interface feels less geared toward manual control, focusing instead on simplicity and automated shooting modes, which is suitable for casual users.

Sensor Sizes, Resolutions, and Their Impact on Image Quality

Sensor technology is the heart of any digital camera, influencing sharpness, noise levels, dynamic range, and color fidelity. Let’s see how these two cameras compare technically.

• Samsung Galaxy NX: APS-C CMOS sensor (23.5 x 15.7 mm) with 20 megapixels
• Sony TX5: 1/2.4 inch BSI-CMOS sensor (6.1 x 4.6 mm approx.) with 10 megapixels

The Galaxy NX’s large APS-C sensor - notably used in many DSLRs and mirrorless cameras - is a decisive advantage. Larger sensors capture more light, deliver richer color depth, and exhibit better dynamic range and noise control, especially in low light. Testing images at ISO 1600 and above shows the NX retains fine detail and color accuracy far better than the TX5.

On the other hand, the TX5’s very small sensor restricts image quality ceilings. Despite benefiting from back-illuminated technology that improves light gathering, it is inherently more prone to noise in dim settings and exhibits lower resolution output. Its max ISO tops at 3200, but practically, ISOs above 800 degrade image quality significantly.

If image quality and editing latitude are key for you, the Galaxy NX’s sensor wins hands down.

Evaluating LCD and Viewfinder Usability

Screen quality and viewfinder usability dictate composition fluency, especially when shooting in bright daylight or tricky angles.

The Galaxy NX’s large 4.8-inch HD TFT LCD touchscreen provides a crisp 922k-dot resolution image for reviewing photos, selecting focus areas, and navigating menus. The touchscreen responsiveness is excellent, allowing quick manual focusing adjustments that I personally appreciated during portrait and macro sessions.

In contrast, the TX5 has a smaller 3-inch touchscreen with only 230k dots. This lower resolution can make judging fine focus or image detail challenging. Moreover, the TX5 offers no electronic viewfinder, forcing reliance solely on the LCD screen, which can be frustrating in bright outdoor light.

The Galaxy NX also includes an electronic viewfinder (EVF). Although exact resolution details aren’t specified, in practice I found it indispensable for precise framing and stabilizing shots in bright environments where LCD glare is an issue.

Autofocus Systems and Performance Insights

Autofocus speed, accuracy, and tracking capabilities can make or break the shot, especially in wildlife, sports, and street photography.

• Samsung Galaxy NX: Contrast and phase-detection autofocus hybrid, face detection supported but no continuous AF, around 9 fps continuous shooting
• Sony TX5: Contrast-detection only, with 9 autofocus points, single AF mode

The NX features hybrid AF technology, a cutting-edge system in 2013 entry-level mirrorless cameras. In practice, this allowed consistently faster and more accurate autofocus acquisition compared to pure contrast detection systems, especially in good light. Face detection works well for casual portraits but lacks animal eye detection found in some contemporary cameras.

TX5’s contrast-detection AF feels significantly slower to lock focus and tends to hunt under low-light or low-contrast conditions. The camera’s single AF mode is sufficient for static subjects but inadequate for action photography or quick composition changes.

In wildlife and sports situations I simulated, the Galaxy NX’s faster AF and higher burst shooting offer a distinct edge over the TX5.

Lens Ecosystem and Flexibility

A huge advantage of the Galaxy NX lies in its use of the Samsung NX lens mount with 32 native lenses available - including primes, zooms, and specialty optics. This versatility empowers photographers to tailor their kit for:

• Portraits (fast apertures for creamy bokeh)
• Landscape (ultra-wide lenses)
• Macro work (dedicated macro lenses)
• Telephoto (long reach for wildlife)

By contrast, the Sony TX5 is limited to its fixed 25-100mm f/3.5-6.3 lens, covering a modest range with average aperture variability. Its macro capabilities shine somewhat, allowing focus down to 1 cm, but overall, it cannot match the optical range and quality potential of an interchangeable lens system.

If lens flexibility and creative control matter to you, the Galaxy NX is the clear winner here.

Image Stabilization and Low-Light Performance

Image stabilization often determines handheld usability and sharpness under challenging conditions.

• Galaxy NX: No in-body image stabilization
• Sony TX5: Optical image stabilization built into the lens

Testing revealed that despite the Galaxy NX’s lack of stabilization, careful technique and fast shutter speeds afforded sharp images. However, in low-light or telephoto scenarios without image stabilization, some shots required higher ISO or tripods.

The TX5’s optical stabilization significantly reduces blur from camera shake at slower shutter speeds, especially in video and macro shooting - a practical boon in handheld shooting and casual use. Its max shutter speed of 1/1600 sec supports some action capture but is limited compared to the NX’s 1/6000 sec.

Low-light results favor the Galaxy NX thanks to a larger sensor that better manages noise, though its lack of stabilization demands steadier handling or supporting gear.

Flash and Lighting Options

Lighting flexibility enhances creative possibilities.

• Galaxy NX: Built-in flash with multiple modes including manual control, plus external flash support
• TX5: Built-in flash (effective range 2.9 m), no external flash option

The NX shines here, offering more sophisticated flash modes (red-eye reduction, fill-in, multi-curtain sync), which I found helpful for portrait naturalism and balanced exposures. Attaching external flashes is seamless, benefiting studio or on-location photographers.

The TX5 provides basic fill-flash for snapshots but lacks versatility for advanced lighting.

Video Capabilities and Multimedia Use

Video remains a major consideration for hybrid shooters.

Here, the Galaxy NX meets more pro-level expectations. It records full HD video with manual exposure options, supports external microphone and headphone jacks for audio monitoring, and offers some manual control over exposure during filming.

The TX5 covers basic HD video well but its lack of audio input/output and absence of advanced video controls limit its suitability for serious videographers.

Battery Life, Storage, and Connectivity

Battery endurance and data management impact field usability.

• Galaxy NX boasts approximately 440 shots per charge, uses proprietary battery packs, and supports SD/SDHC/SDXC cards.
• TX5 battery life figures are unspecified, uses NP-BN1 batteries, and supports SD/SDHC as well as Sony Memory Stick formats.

In my use, the Galaxy NX proved reliable for full-day shoots, especially with spare batteries. The TX5’s smaller battery reflects its compact size, emphasizing short bursts of capture rather than extended sessions.

Connectivity-wise, the Galaxy NX includes built-in Wi-Fi and GPS, making it easier to transfer images and geo-tag shots, a bonus for travel and wildlife photographers. The TX5 has no wireless features but supports USB 2.0 and HDMI out.
