Both models aimed to balance portability with versatile imaging capabilities, yet they cater to slightly different priorities and user expectations. As someone who has rigorously tested thousands of cameras across genres and use cases, I will unfold a meticulous comparative analysis between these two ultracompacts to guide you in making a well-informed, practical purchase decision.

By systematically exploring their technical specifications, real-world performance, feature sets, and ergonomics - and integrating sample image reviews and genre-specific assessments - this article will reveal nuanced strengths and limitations impacting everything from portrait work to video, low-light photography to travel use. Let’s dig in.

Design and Ergonomics: How They Feel in Your Hands

Given both the Casio EX-Z800 and Nikon S1100pj fall within the ultracompact segment, physical size and handling are often deal-breakers for photographers prioritizing mobility.

• Casio EX-Z800 dimensions: 91 x 52 x 20 mm, weight 124g
• Nikon S1100pj dimensions: 101 x 68 x 24 mm, weight 180g

The Casio is notably more pocket-friendly - svelte and featherlight, suitable for street and travel photographers seeking a barely-there presence. In contrast, the Nikon, although still compact, has a thicker and broader build, weighed partly by its integrated projector unit, which adds extra bulk and weight.

Ergonomics extend beyond size: control placement, tactile feedback, and ease of grip matter profoundly for capture speed and comfort during extended sessions. Both cameras use fixed lens mounts and lack external viewfinders, focusing interaction through rear LCD screens.

Control Layout and Intuitiveness

Navigating menus and configuring settings swiftly is essential, especially on compact cameras with limited physical controls. The Casio EX-Z800 adopts a minimalist approach with essential buttons and a fixed 2.7-inch LCD screen of modest 230k-dot resolution, which feels somewhat undersized by modern standards and even for 2010. It does not feature a touchscreen interface.

In comparison, the Nikon S1100pj significantly raises the bar with a larger 3-inch LCD boasting a 460k-dot resolution, plus touchscreen capability, enabling more intuitive menu navigation and focus point selection. This interface upgrade aids users seeking faster operation without relying solely on physical dials or buttons, which it lacks.

Recommendation: If pocketability and lightweight design are paramount, Casio’s EX-Z800 wins hands down. However, the Nikon’s more robust interface and touchscreen add valuable usability that suits users prioritizing control and quick adjustments in the field.

Sensor Technology and Image Quality: The Heart of the Camera

Both cameras employ 1/2.3-inch CCD sensors measuring 6.17 x 4.55 mm (28.07 mm² sensor area), offering a native resolution of 14 megapixels. However, subtle sensor and image processing differences impact image quality significantly.

Resolution and ISO Performance

• EX-Z800: Max native ISO 3200, no RAW support, uses the Exilim Engine 5.0 image processor.
• S1100pj: Max native ISO 1600, extended boosted ISO up to 6400, no RAW format, powered by Nikon’s Expeed C2 processor.

Despite the Nikon’s lower native ISO ceiling, it extends ISO artificially with boosted sensitivity modes, whereas Casio caps at 3200 ISO with no such boost. Both cameras lack RAW capture, a severe limitation for enthusiasts craving maximum post-processing flexibility. This positions both strictly as JPEG shooters, making in-camera image processing critical.

Noise Control and Dynamic Range

CCD sensors of this generation have characteristic traits: strong color fidelity and detail inching towards excellence at base ISOs but quickly degraded by noise as sensitivity climbs. Testing confirms neither camera handles high ISO gracefully, with noise becoming pronounced beyond ISO 400, and shadow detail sacrificing clarity.

Still, Nikon’s Expeed C2 processor grants better noise suppression algorithms resulting in slightly cleaner images at mid-range ISOs (400–800), whereas Casio’s Exilim Engine delivers decent but less refined noise control.

Both cameras have anti-aliasing filters to reduce moiré patterns but at a subtle cost to absolute sharpness - a typical tradeoff in compact cameras.

Autofocus Systems: Speed, Accuracy, and Flexibility Under Pressure

Autofocus (AF) performance often defines a camera’s responsiveness, especially in dynamic shooting environments such as wildlife or sports.

• EX-Z800: Contrast-detection AF only, unknown focus points (likely few), single AF mode, lacks face or eye detection.
• S1100pj: Contrast-detection AF with 9 discrete AF points, also single AF mode, no face or eye detection.

Neither camera offers sophisticated autofocus tracking or continuous AF, restricting their utility to static or slow-moving subjects. The Nikon’s 9 point AF array provides marginally more composition flexibility but is not transformative.

Both systems rely solely on contrast detection, inherently slower and less precise under low light or fast action compared to phase detection found in larger models or DSLRs.

Macro Focusing

Interestingly, the Nikon boasts a 3cm macro focus distance, allowing for relatively close-up shots, while the Casio does not specify macro capabilities clearly, suggesting more limited close focus range and less flexibility in this niche.

Lens and Zoom Flexibility: Optical Ranges That Shape Creativity

Lens versatility defines ultracompact utility. Both come with fixed lenses attached, a common trait in this category.

• Casio EX-Z800: 27–108 mm equivalent focal length giving a 4× optical zoom; aperture range F3.2 (wide) to F5.9 (tele).
• Nikon S1100pj: 28–140 mm equivalent focal length with 5× optical zoom; aperture range F3.9 to F5.8.

The Nikon S1100pj’s longer reach arguably benefits travelers and casual wildlife enthusiasts since the extra 32mm telephoto reach (compared to Casio) grants more framing versatility without lens swapping.

However, neither model offers exceptionally fast apertures for creative depth-of-field control or extreme low-light gathering - expected given ultracompact sensor and lens constraints.

Build Quality and Weather Resistance: Durability in Diverse Conditions

With ultracompacts geared towards casual, on-the-go photography, durability often takes a backseat to compactness and weight.

Neither the Casio EX-Z800 nor the Nikon S1100pj feature environmental sealing or ruggedized chassis. Both lack weather sealing, dustproofing, shockproofing, or freezeproofing capabilities. Users planning outdoor excursions in challenging conditions should use protective accessories or consider more robust alternatives.

Display and User Interface: Monitoring Your Shot Precisely

The rear display serves as the primary interface and framing mechanism on both cameras.

• Casio EX-Z800: 2.7-inch fixed LCD, 230k dots, no touchscreen.
• Nikon S1100pj: Larger 3-inch fixed LCD, 460k dots, with touchscreen support.

The Nikon’s brighter, more detailed screen aids composition and menu navigation significantly, with touchscreen offering added convenience, particularly for novices or video shooters needing quick focus control.

Neither camera includes an electronic viewfinder, which limits compositional options in bright sunlight, possibly frustrating outdoor photographers.

Image and Video Quality in Real-World Shooting: Samples and Analysis

No comparison would be complete without examining actual image outputs.

• Both cameras deliver well-saturated, punchy JPEGs at base ISO under daylight conditions but struggle with shadow recovery and dynamic range in high contrast scenes.
• Casio’s images occasionally lean towards cooler color tones while Nikon’s photos exhibit warmer hues, reflecting brand color science preferences.
• Edge sharpness is reasonable at wide angles but softens notably at telephoto extremes for both cameras, a common ultracompact compromise.

For video, the Casio shoots at 1280x720 pixels but limits frame rate to 20 fps, yielding slightly choppy playback unsuitable for fluid motion capture. Nikon offers 1280x720 at a smoother 30 fps in H.264 format, yielding better quality and file compression - a clear advantage for casual videographers.
