A fundamental differentiation is sensor size and technology:

• Casio EX-S7: Uses a 1/2.3-inch CCD sensor measuring just 28.07 mm², delivering 12 MP resolution (4000x3000). This small sensor restricts dynamic range, low-light performance, and color fidelity compared to larger types. CCD technology, though capable of good color rendering, has generally been surpassed by modern CMOS sensors regarding speed and noise control.

• Samsung NX1: Equipped with a large APS-C BSI-CMOS sensor (368.95 mm²), offering 28 MP (6480x4320) resolution. The backside illumination (BSI) design significantly improves sensitivity and readout speed. This sensor produces excellent dynamic range (claimed 13.2 EV) and color depth (24.2 bits), positioning it effectively for professional applications.

From practical experience, the NX1’s sensor noise performance and detail rendition at native ISO 100 to 25600 are far superior, whereas the EX-S7’s tiny CCD sensor struggles beyond ISO 1600 with marked noise and compromised highlight and shadow detail.

Lens and Focal Length Capabilities: Fixed vs. Interchangeable

The EX-S7 comes with a non-removable 36–107 mm (equivalent) zoom lens (3x optical zoom) with an aperture range of F3.1 to F5.6. While convenient for snapshot versatility, its limited range, aperture, and lack of lens interchangeability confine compositional and creative control severely.

In contrast, the Samsung NX1 uses the NX mount with over 32 lenses available. This broad selection spans ultra-wide primes, fast portrait lenses, telephoto zooms optimized for wildlife/sports, and specialty optics such as macro and tilt-shift. The ability to choose optics appropriate to specific genres vastly expands photographic possibilities.

User Interface, Controls, and Handling

The EX-S7’s minimalistic button layout and absence of manual exposure modes reflect a point-and-shoot philosophy: keep it simple, auto-dominant, and accessible. Conversely, the NX1’s SLR-style control layout includes dedicated dials for shutter speed, aperture, ISO, exposure compensation, and multiple customizable buttons. The inclusion of a top status LCD panel further aids quick parameter review without menu diving.

The NX1's tiltable, high-resolution touchscreen (3-inch, 1036k dots) supports intuitive focus selection and menu navigation, whereas the EX-S7’s fixed 2.7-inch, 230k pixel screen lacks touch capabilities and fine detail, limiting usability in bright conditions.

Autofocus Systems: Speed, Accuracy, and Tracking

The autofocus disparity between these cameras is profound:

• Casio EX-S7: Contrast-detection AF only, single-point, no face or eye detection, no continuous tracking. This results in slower AF speeds and limited accuracy for moving targets or dynamic scenes.

• Samsung NX1: Hybrid AF system combining contrast and phase detection with 209 AF points (153 cross-type). Features include continuous AF, selective and multi-area AF, advanced face detection, and subject tracking. These capabilities enable fast, reliable focus acquisition even in challenging environments or with erratically moving subjects - a key advantage for sports and wildlife photography.

Testing clearly shows the NX1’s autofocus system significantly outperforms the EX-S7 for action and low-light focusing scenarios.
