What I found: The Galaxy NX’s larger body facilitates a steady grip and more intuitive manual shooting, essential for serious photography. The TX9 shines for travel, street, or casual snapshots due to its slim form factor - it slides casually into a pocket or clutch without fuss.

Top-Down: Control Layout and Accessibility

Control placement can make or break shooting fluidity, especially for manual exposure adjustments.

Samsung’s mirrorless design embraces dedicated physical dials and buttons, including exposure compensation, shutter priority, aperture control, and customizable functions. The presence of a hot shoe, built-in flash, and external flash options add versatility.

Sony’s TX9 offers a simpler top deck with shutter and power buttons, reflecting its automated usage model. There is no mode dial or manual exposure control, and flash modes are limited.

My take: For photographers seeking creative control and tactile feedback, the Galaxy NX leads. The TX9 is more about ease of use and quick shooting without diving into menus.

Sensor Technology: The Heart of Image Quality

The fundamental difference lies here - sensor size and technology define image quality, noise performance, dynamic range, and resolution.

APS-C vs 1/2.3-inch
The Galaxy NX’s APS-C sensor is roughly 13 times larger than the TX9’s sensor. Larger sensors capture more light, which improves dynamic range, color depth, and low-light performance.

What I tested: The Galaxy's images exhibit far better detail reproduction and tonal gradation, especially in challenging lighting. Noise is well-controlled up to ISO 3200, with usable results higher than 6400 in some cases. The TX9 struggles beyond ISO 800, with noticeable noise and softer detail. The BSI (backside illuminated) CMOS sensor in the TX9 helps its low-light sensitivity relative to typical compacts but cannot match the APS-C sensor’s capability.

The Galaxy supports RAW file capture, empowering photographers with robust post-processing latitude. The TX9 only outputs JPEG, limiting workflow flexibility for enthusiasts.

Viewing and Composing Images: Displays and Viewfinders

Samsung Galaxy NX features a large 4.8-inch HD TFT touchscreen, enabling precise touch focus and menu navigation. It also includes an electronic viewfinder, though the resolution is unspecified and coverage details lacking.

Sony TX9 relies solely on a 3.5-inch LCD touchscreen, with no viewfinder option.

Hands-on insight: In bright outdoor conditions, the Galaxy NX’s EVF proved indispensable for framing and minimizing glare. The large rear touchscreen on both cameras is responsive, but I preferred the Galaxy’s UI for manual focus confirmation and exposure preview. The TX9’s screen loses some visibility under direct sunlight, typical for compacts without eye-level finders.

Lens Ecosystem and Flexibility: Interchangeable vs Fixed

A critical dividing line here is the Galaxy NX’s interchangeable Samsung NX mount supporting 32 native lenses, ranging from wide-angle primes to telephoto zooms. This opens possibilities for specialty photography like macro, wildlife, and portraiture with shallow depth-of-field control.

The TX9 comes with a fixed 25-100 mm (4x optical zoom) lens with a max aperture of f/3.5-4.6 - typical for compact cameras.

From experience: The ability to choose and change lenses is the defining factor for photographers wanting to advance creatively. The Galaxy NX invites experimentation; I tested a variety of prime and zoom lenses, all delivering the APS-C sensor’s punchy image quality.

The TX9 suits users wanting an all-in-one tool without fuss but will limit shooters chasing bokeh-rich portraits or telephoto reach.

Shooting Performance: Autofocus and Continuous Shooting

The Galaxy NX’s hybrid AF system provides faster, more reliable focus acquisition, even in moderately low-light or when tracking moving subjects. It also supports face detection autofocus, improving portrait sharpness.

The TX9’s contrast-detection AF is adequate for still subjects but tends to hunt or lag in dynamic situations.

Having tested both side-by-side on moving subjects, the Galaxy NX tracks focus more consistently without losing lock. The 9fps frame rate is competitive for entry-level mirrorless, suitable for some basic sports or wildlife action.

Field Tests Across Popular Photography Genres

Portraits: Skin Tones, Bokeh, and Eye Detection

• Galaxy NX: With APS-C sensor and array of lenses (including fast primes), skin tones render naturally with pleasing tonal gradation. The camera’s face detection AF ensures sharp focus on eyes, greatly improving portrait results.
• TX9: Smaller sensor and fixed lens restrict depth-of-field control, so backgrounds are less creamy. Skin tones are acceptable but lack the subtle nuances and dynamic range of APS-C.

Verdict: Galaxy NX is the clear winner for portrait work; the TX9 is for casual snapshots.

Landscapes: Dynamic Range, Resolution, and Durability

The Galaxy NX’s 20MP APS-C sensor and RAW support deliver outstanding landscape detail and the latitude for adjusting exposure and color post-shooting. With proper lenses, I could capture expansive scenes with excellent sharpness.

The TX9 records 12MP JPEGs which can suffice for social sharing but are limited for large prints or detailed post-processing. Neither camera offers weather sealing or robust build suitable for harsh environments.

Wildlife and Sports: Autofocus Speed, Telephoto Performance, Burst Rates

The Galaxy NX excels due to interchangeable telephoto lenses, hybrid AF, and 9fps burst shooting. It gave me confidence in following wildlife movement and capturing decisive moments.

The TX9’s 4x zoom is restrictive for full-frame wildlife or sports needs, and slower contrast AF means missed shots in fast action. Its 10fps burst is impressive, but AF limitations reduce usefulness.

Street Photography: Discreteness, Portability, and Low Light

Here, the TX9, with its ultra-compact size and stealthy profile, shines - perfect for candid shooting and travel street photography.

While the Galaxy NX is bigger and more obvious, it has better low-light sensitivity and manual control for creative street portraits and night scenes.
