Unpacking the Physical Form and Ergonomics

The tactile experience of a camera heavily influences shooting comfort and operational efficiency, particularly in dynamic or prolonged scenarios. Let us first examine how these cameras stack up in terms of size, weight, and control layout.

Dimensions and Weight

• Casio EX-H10: Compact dimensions (102x62x24mm) and a lightweight body at 194g.
• Olympus SP-800 UZ: Considerably larger (110x90x91mm) and heavier at 455g.

The EX-H10’s slim and lightweight profile makes it a clear advantage for photographers seeking pocketability and discretion - characteristics vital for street and travel photography. In contrast, the SP-800 UZ’s bulk comes primarily from its extensive lens assembly and larger grip, which, while reducing portability, likely improves handling for telephoto use.

Grip and Handling

Despite the Casio’s compactness, its minimalist form provides limited physical grip and control customization - no dedicated dials for exposure compensation or priority modes were included. The Olympus, although bigger, features a more substantial handgrip, allowing firmer holding during telephoto shooting, reducing shake-induced blur. However, its boxier profile can be unwieldy during fast-moving shooting scenarios or extended handheld use.

Control Layout

Neither model offers extensive manual controls - both lack aperture and shutter priority modes, limiting exposure customization to auto or basic program modes. The SP-800 UZ stands out with 143 autofocus points and AF tracking capability, reflected in its more complex user interface and multidirectional AF point selection, offering nuanced focusing in varied compositions. The EX-H10 relies on a simplified, center-weighted AF without tracking, which restricts its responsiveness to fast subjects.

Screen and Viewfinder

Neither camera includes an electronic viewfinder. Both utilize a fixed 3-inch LCD with 230k pixel resolution, consistent with compact cameras from their release period.

In real-world usage, screen visibility under bright sunlight and responsiveness were similar and standard for their class. The lack of touchscreen functionality on both models means menu navigation relies solely on physical buttons, a factor that could slow workflow when adjusting settings rapidly.

Sensor Technology and Image Quality

Sensor performance remains paramount for image quality and determines how well a camera adapts to different shooting scenarios. Both cameras use 1/2.3" CCD sensors but differ in resolution and processing capabilities.

Resolution and Detail

The SP-800 UZ’s marginally higher resolution (14MP versus 12MP) affords slightly finer detail rendition, particularly noticeable when cropping or printing large images. However, given the small sensor size, noise and diffraction often undermine resolution benefits at smaller apertures or higher ISO settings.

ISO Performance

CCD sensors in this class notoriously underperform compared to modern CMOS types in high ISO scenarios. Both models exhibit substantial noise past ISO 800, with the Olympus’s advanced TruePic III processor providing slightly better noise reduction without overly smudging fine detail. The Casio performs adequately at base to mid ISO but introduces visible chroma noise at ISO 1600 and above.

Dynamic Range and Color

Neither model has published DxOMark scores, but subjective testing revealed limited dynamic range, with shadow clipping and highlight blowout prevalent in challenging lighting. Color science differs: the Casio tends toward a warmer palette, which might appeal for skin tones in portraiture, whereas the Olympus renders colors more neutrally and contrasty, beneficial for landscapes.

Autofocus Systems in Practice

Autofocus precision, speed, and tracking define usability for most photographic genres, especially wildlife and sports.

Casio EX-H10

• Single contrast-detection AF system
• No continuous or tracking AF
• Limited to center-weighted AF zone
• Manual focus available but requires menu access rather than dedicated focus rings or buttons

This single-point AF limits usability on any subject with movement or non-central framing, as users must recompose after locking focus.

Olympus SP-800 UZ

• Contrast-detection AF with 143 selectable points
• AF tracking support for moving subjects
• Multiarea AF mode allows flexible composition

The abundance of focus points combined with advanced tracking improves user results when capturing wildlife or sports. However, lack of phase-detection means low light or low contrast AF can be sluggish.

Zoom Lenses and Optical Performance

Lens versatility is a highlight of these superzoom compacts, but maximum zoom ranges and aperture behavior diverge signficantly.

Telephoto Reach

Olympus’s 30x zoom significantly outperforms the Casio’s 10x, offering exceptional reach essential for wildlife and sports. This advantage is tempered by greater size/weight of the lens assembly and correspondingly reduced maximum apertures toward telephoto ends.

Aperture Range

Olympus begins at a wider f/2.8 aperture at the wide end, enhancing low light performance and depth of field control in landscapes and portraits, compared to Casio’s relatively modest f/3.2 max aperture.

Macro Capability

Olympus’s ability to focus as close as 1 cm is a meaningful benefit for macro enthusiasts who require fine detail and minimal working distance. Casio’s 7 cm minimum makes it less suited for extreme close-ups.
