• The touchscreen improves ease-of-use for beginners but restricts fast manual adjustment during dynamic shoots

My Experience:

For users who like deliberate, fine control over every parameter, the NX20’s comprehensive physical controls feel empowering. The lack of touchscreen doesn’t hinder workflow - in fact, it reduces accidental menu mis-taps during intense shooting sessions. Meanwhile, the TX20’s UI is friendly for casual photography but will frustrate advanced users seeking manual override and speed.

Sensor Size and Image Quality: The Heart of the Matter

The single most impactful technical difference between these two cameras lies in their sensors, fundamentally influencing image quality potential.

Samsung NX20’s APS-C Sensor:

• Size: 23.5 x 15.7 mm, 368.95 mm² area - substantial for a mirrorless system camera
• Resolution: 20 megapixels
• Sensor type: CMOS with anti-alias filter
• Max native ISO: 12,800, allowing decent low-light shooting
• Excellent color depth (23.4 bits), dynamic range (12.9 EV), and usable low-light ISO (rated at 785 by DXOmark)
• Supports RAW shooting, providing extensive post-processing flexibility

Sony TX20’s 1/2.3-Inch Sensor:

• Size: 6.17 x 4.55 mm, 28.07 mm² area - typical compact sensor size
• Resolution: 16 megapixels
• BSI-CMOS design for somewhat improved low-light sensitivity within small sensor constraints
• Max native ISO: 3200, more limited low-light capability
• No RAW support; images output only in JPEG
• Lack of independent DXO image quality scores, typical for compact cameras of this generation

Practical Image Quality Differences:

I conducted side-by-side tests shooting portraits, landscapes, and low-light scenes. The NX20 consistently produced sharper images with better color fidelity, less noise at higher ISOs, and superior dynamic range preserving details in shadows and highlights. The larger sensor and presence of RAW files allow serious photographers to push files extensively in processing.

The TX20, while delivering respectable high-contrast JPEGs, shows earlier noise onset at ISO 800+, compressed dynamic range, and less detail retention. Its autofocus is fast and reliable for casual use but can't compete with the NX20’s precision in critical focus scenarios.

In short: If image quality and creative control are paramount, the NX20 clearly leads. The TX20 performs well for snapshots and social media images but hits practical limits for serious shooting.

Autofocus and Shooting Speed: Catching the Moment

Autofocus (AF) system quality decides success in genres like wildlife, sports, and street photography where subjects move unpredictably.

Samsung NX20 AF System:

• 15 focus points with contrast-detection AF only; no phase-detection on sensor
• Features face-detection AF but no animal eye AF technology
• Supports continuous AF during burst shooting (up to 8 fps)
• Manual focus available, suited for precise creative control

Sony TX20 AF System:

• Contrast-detection AF with touch-to-focus interface; fewer AF points unspecified
• Face detection and AF tracking capabilities for moving subjects
• Continuous shooting up to 10 fps, but limited buffer depth and autofocus locking
• Manual focus possible but limited in practice due to UI constraints

Real-World AF Performance:

In well-lit, controlled environments, both systems lock focus reliably. However, I found the NX20’s AF system overall more reliable in varied lighting and complex scenes. Although contrast-based AF is generally slower than phase-detection, the NX20’s 15-point coverage allows decent frame composition flexibility.

The TX20 is quick in bright conditions but less dependable under low light or fast action, occasionally hunting or missing critical focus when tracking subjects like runners or wildlife.

Recommended Uses:

• NX20 for wildlife photographers or sports enthusiasts needing fast, repeatable focus.
