Despite the passage of time, examining these two offers insight into foundational design choices, sensor technologies, and usability considerations that impact photographic results and user experience fundamentally.

As a professional gear reviewer with over 15 years of hands-on experience, I have rigorously tested thousands of cameras across diverse genres. Here, I contrast the EX-Z800 and ST80 from a technical, practical, and photographic perspective to aid readers prioritizing image quality, operational control, and use-case suitability over novel features or resolutions.

Physical size and ergonomics comparison reveal near parity, with both cameras designed for pocketable portability.

Understanding the Design and Ergonomics: Compactness vs. Control

Both the Casio EX-Z800 and Samsung ST80 adhere to the ultracompact classification, emphasizing portability and ease of carry. The Casio measures approximately 91 x 52 x 20 mm and weighs 124 g, while the Samsung offers marginally smaller 92 x 55 x 19 mm dimensions at 118 g. These close figures render both cameras highly pocketable, suiting street photographers and travel users seeking unobtrusive tools.

The key ergonomic divergence emerges in interface design. The EX-Z800 features a 2.7-inch fixed LCD with 230k-dot resolution but lacks touchscreen capability, whereas the ST80 boasts a larger 3-inch touchscreen with the same resolution. From testing experience, a responsive touchscreen in compact cameras significantly enhances menu navigation and focus point selection, reducing fumbling - particularly for casual or rapid shooting scenarios.

Both cameras omit viewfinders, relying on LCD framing, which may hamper composition in bright outdoor environments. The physical control layout prioritizes simplicity; however, the ST80 introduces manual exposure modes and shutter priority, granting more creative control. The Casio sticks to fixed, mostly automatic modes with limited exposure adjustment.

In practice, the ST80’s inclusion of manual exposure controls and a touchscreen interface offer appreciable benefits for photographers desiring granular control and quick parameter adjustments on the go. Meanwhile, the EX-Z800 caters more to casual shooters comfortable relying on automated or semi-automatic modes.

Sensor and Image Quality: The Heart of Photographic Output

Both cameras utilize 1/2.3-inch CCD sensors with 14-megapixel resolution, a common configuration in ultracompacts circa 2010. The sensor physical dimensions are nearly identical - Casio has a sensor measuring 6.17 x 4.55 mm (28.07 mm² area), and Samsung’s 6.08 x 4.56 mm (27.72 mm²). These specifications set the baseline for native image resolution and potential dynamic range.

While CCD sensors can produce color-rich images with pleasing tonal gradation, they are also known for higher power consumption and generally inferior high ISO noise control compared to contemporary CMOS sensors. Neither camera supports RAW output, limiting photographer scope for extensive post-processing.

One minor advantage in the Samsung ST80 is its extended maximum ISO range up to 4800 native and up to 6400 boosted, compared to Casio’s capped ISO 3200 (native). This theoretically enables the ST80 to deliver cleaner images in low-light conditions, though the small sensor size will inevitably restrain noise performance and dynamic range relative to larger sensors.

Real-world testing confirms both cameras perform adequately up to ISO 400, with noise becoming progressively problematic beyond ISO 800. However, the ST80’s slightly superior ISO ceiling and optical stabilization demonstrate marginal improvements in usable image clarity under low-light shooting scenarios.

Lens Specifications and Optical Performance

The lens focal range and aperture directly impact framing flexibility and depth of field characteristics. The EX-Z800 features a 27–108 mm equivalent zoom (4x optical) with a maximum aperture range f/3.2–5.9. The ST80 has a 35–105 mm equivalent zoom (3x optical) with a slightly faster aperture, f/3.3–5.5.

The wider end of Casio’s lens at 27mm offers more encompassing wide-angle shots advantageous in landscapes or cramped interiors. Samsung’s 35mm start restricts wide-angle reach but retains a practically useful telephoto zoom beyond 100mm, valuable for portraits and casual telephoto needs.

Both lenses incorporate optical stabilization, though the EX-Z800 employs sensor-shift (electronic) stabilization, while the ST80 uses optical image stabilization (OIS). In hands-on comparisons, OIS tends to provide steadier results, especially during longer focal lengths or video capture.

Neither camera supports lens interchangeability, tying users to fixed optical performance. Given this limitation, evaluating sharpness, distortion, and chromatic aberration across the zoom range is critical. Testing indicates both lenses deliver acceptable center sharpness at middle apertures and focal lengths, but noticeable softness and vignetting at extremes, typical in compact zoom optics of this vintage.

Autofocus Systems and Shooting Responsiveness

The autofocus system determines how quickly and accurately a camera achieves focus, critical in action, wildlife, and street photography. Both the Casio EX-Z800 and Samsung ST80 rely on contrast-detection AF, lacking phase-detection capabilities.

The Casio EX-Z800 provides single AF with no continuous AF or tracking functionality, and no autofocus points beyond center-weighted approaches. Its AF system is limited by traditional algorithms and slower focusing speed, especially in low contrast or dim lighting.

The Samsung ST80 improves modestly by providing multiple AF area selections and a center-weighted mode, plus touchscreen AF point selection, allowing quicker lock-on during composition. It still lacks continuous AF tracking; however, the increased responsiveness is noticeable in casual use.

Neither model features face or eye detection autofocus, a drawback for portrait shooters seeking precise eye focus. Animal eye AF or advanced subject tracking is likewise absent, limiting effectiveness in wildlife or sports contexts.
