Sensor Technology and Image Quality: The Heart of the Camera

Image quality ultimately boils down to sensor capabilities. Here, the differences couldn’t be more pronounced.

The EX-Z550 houses a 14MP 1/2.3" CCD sensor measuring about 6.17 x 4.55 mm with a sensor area of 28.1 mm². CCD sensors from this era are known for decent color rendition but limited dynamic range and noise performance, especially at higher ISOs.

The NX1 features a 28MP APS-C (23.5 x 15.7 mm) back-illuminated CMOS sensor with a surface area of 369 mm² - over 13 times larger than Casio’s. This significant increase yields markedly better resolution, improved noise control, and higher dynamic range critical for professional-grade imaging.

Samsung decoupled the AA filter on the NX1 to maximize sharpness, further emphasizing image fidelity. On DxOMark scale (though EX-Z550 not tested), NX1 earns an impressive 83 overall score, with 24.2 bits color depth, 13.2 EV dynamic range, and low light ISO performance up to 1363.

Hands-on, I found the NX1 produces images with striking detail retention, clean shadows, and crisp highlights, even under challenging lighting. The EX-Z550 images are fine for snapshots but quickly show noise and lack fine detail when enlarged or printed.

Summary:

• EX-Z550: Small CCD sensor suitable for casual point-and-shoot but limited detail and noisy at higher ISO.
• NX1: Large APS-C BSI-CMOS sensor delivering top-tier image quality rivaling DSLRs.

Viewing and Composing: Screens and Viewfinders

Composition tools significantly affect shooting accuracy.

The Casio EX-Z550 sports a fixed 2.7-inch LCD with only 230k pixels - basic, with moderate brightness and viewing angles. Lack of touchscreen limits interaction, and absence of any viewfinder means outdoor shooting can be challenging in bright light.

In contrast, Samsung’s NX1 includes a high-resolution 3-inch tilting touchscreen LCD panel with over 1 million dots, facilitating intuitive menu navigation and touch focus. Additionally, it is equipped with a bright 2360k-dot OLED Electronic Viewfinder (EVF) with 100% coverage and 0.7x magnification - ideal for exact framing and stability in bright conditions.

In my daily use, the NX1’s EVF was a game-changer for tracking fast-moving subjects and precise manual focusing, especially outdoors, while the EX-Z550 LCD requires more care in bright sunlight.

Summary:

• NX1: Professional-grade EVF, sharp tilting touchscreen, vastly enhancing composition precision.

Autofocus Systems: From Point-and-Shoot to Pro Precision

Autofocus remains one of the most critical operational factors, differentiating casual shooters from professionals.

The EX-Z550 operates with a simple, contrast-detection AF system, offering just single-shot autofocus with no subject tracking or face detection capabilities. AF points are unspecified and limited, making quick focusing on moving targets almost impossible.

The NX1’s autofocus system is markedly advanced: 209 AF points total, with 153 cross-type phase-detect points distributed across the frame, augmented by contrast detection for fine accuracy. It supports continuous AF, eye detection, face detection, and even multi-area tracking, providing fluid performance for sports, wildlife, and dynamic scenarios.

During my tests, the NX1’s AF was lightning fast, locking focus in under 0.1 seconds in good light, and retaining reliable subject tracking even at 15 frames per second burst rates. The EX-Z550 struggled with slower lock times and hunting, suitable only for static subjects.
