Casio EX-Z800 vs. FujiFilm FinePix Z700EXR: An Ultracompact Camera Showdown

In my many years of reviewing cameras - spanning rugged outdoor gear, flagship mirrorless systems, and compact point-and-shoots - I’ve developed a keen understanding of what makes a camera truly worthwhile in real-world scenarios. Today, I’m diving deep into a comparison between two ultracompact cameras from the early 2010s that caught my eye: the Casio EX-Z800 and FujiFilm FinePix Z700EXR. Both positioned as sleek, pocket-friendly companions for casual shooters, these models pack very different feature sets under similarly modest shells.

My goal here isn’t to dwell on raw specifications alone, but to share practical insights from hands-on experience and lab testing, decoding how these cameras perform across various photography disciplines, usability factors, and budget considerations. Whether you’re a street photographer, travel enthusiast, or hobbyist craving simplicity, this article will help you navigate the trade-offs and highlight which of these two contenders can best serve your creative intent - even a decade after their launch.

Size, Feel, and Handling: Small Cameras with Subtle Differences

At first glance, the Casio EX-Z800 and FujiFilm Z700EXR share a similar ultracompact footprint - kingdoms of pocketability with slim profiles around 20mm thick. I weighed both and spent time shooting handheld to evaluate comfort. The Casio tips the scales at a mere 124 grams (including battery), while the FujiFilm is a bit beefier, around 158 grams.

Despite the Casio's slight advantage in lightness and compactness, I found the FujiFilm’s larger grip area and more substantial tactile feedback on buttons made it easier to operate for extended periods without fumbling. It's a push-pull dynamic: Casio exudes unobtrusive minimalism perfect for stealth shooting or travel, whereas FujiFilm leans towards everyday ease at a small cost in size.

I also appreciated the Casio’s clean, almost Spartan design - though this comes at the expense of fewer physical controls. The FujiFilm’s more pronounced dials and buttons lend a reassuring analog feel, which aligns with its manual-exposure mode offerings I’ll elaborate on later.

User Interface and Controls: Managing Complexity and Speed

Ultracompacts can’t cram in deep functionality without complicating usability, so the UX balance here is key. The EX-Z800 sticks to basics - no manual exposure mode or aperture priority, and its autofocus is simple contrast detection with a single focus mode. Navigating menus feels lightweight, but I missed the responsiveness from touchscreen integration.

By contrast, the Z700EXR features a 3.5-inch touchscreen panel that elevates interaction intuitively - especially for focus adjustments and setting exposure compensation. This alone dramatically improves speed for casual shooters and beginners vs. toggling physical button combos.

The FujiFilm also adds manual exposure control, a differentiation that puts it ahead for enthusiasts who want more influence over look and mood without bigger gear. Exposure compensation dialed in with distinct feedback makes me feel more connected to capturing artistic nuances, while the Casio locks you into full auto or limited white balance settings.

Display Quality and Viewfinding: When Bigger and Brighter Matters

The FujiFilm’s 3.5-inch LCD absolutely dwarfs the Casio’s 2.7-inch screen in both size and resolution (460k vs. 230k dots). This makes framing, reviewing photos, and live view shooting easier in diverse lighting. For example, in bright midday sun, the FujiFilm’s brighter panel made compositional adjustments possible without shading the screen - something I struggled with on the EX-Z800 without an electronic viewfinder.

Neither camera includes viewfinders, so those concerned with stability or shooting in glaring conditions may find FujiFilm’s larger screen a legitimate advantage for maintaining composition and focus accuracy.

Sensor and Image Quality: The Heart of the Matter

Both cameras rely on 1/2.3-inch CCD sensors, though the FujiFilm’s sensor is marginally larger in physical dimensions (6.4x4.8mm vs. Casio’s 6.17x4.55mm), offering a tiny edge in light-gathering capability. Pixel count is another interesting contrast: Casio sports 14 MP while FujiFilm trails with 12 MP, but real-world image quality hinges on more than just megapixels.

The FujiFilm’s EXR processor employs intelligent pixel binning and noise-reduction technologies aimed at boosting dynamic range and low-light performance - a significant advantage in challenging conditions. In my controlled ISO tests, the FujiFilm maintained cleaner shadows with reduced grain at ISO 800 and 1600, while the Casio began to visibly degrade past ISO 400.

However, the Casio’s 4x zoom reaches from 27-108mm equivalent focal length versus FujiFilm’s 5x range of 35-175mm, providing wider framing options for casual snapshots. The tradeoff is that FujiFilm’s lens aperture range (F3.9-4.7) offers slightly better low-light responsiveness compared to Casio’s narrower F3.2-5.9, particularly at telephoto.

Real-World Photography Genres: Which Camera Excels Where?

I’ve tested both models across multiple photography disciplines to give comprehensive insights.

Portraits: Rendering Skin and Capturing Expression

Portraiture benefits greatly from good bokeh (lens aperture), color rendering, and autofocus precision. Neither camera is designed to create creamy background separation given fixed lenses with modest maximum apertures and small sensors, but among the two, the FujiFilm’s slightly brighter aperture and EXR sensor produce skin tones with more natural warmth and better highlight retention.

The Casio’s autofocus is purely contrast-based and single-shot, and lacks face or eye detection features. While the FujiFilm also lacks face detection, its autofocus coupled with touchscreen-based focal point selection gave me faster and more confident focusing on subjects’ eyes in my headshots tests.

Both struggle with fine skin tone detail due to sensor limitations, but the FujiFilm’s slightly more advanced processing delivers more flattering portrait colors - definitely something that stood out in indoor, low-light scenarios.

Landscapes: Pushing Resolution and Dynamic Range

For landscapes, resolution, dynamic range, weather resistance, and framing flexibility are essential.

At their core, both cameras have no environmental sealing, so rugged outdoor shooting in wet conditions is off the table without external protection. The FujiFilm's EXR processing gives it a modest edge in capturing highlight/shadow details in high-contrast scenes like sunrise or backlit vistas.

While Casio’s 14MP sensor nominally produces higher-resolution images, FujiFilm’s 12MP with superior noise control yields cleaner files in practice especially at base ISO settings. The FujiFilm also offers wider aspect ratios (4:3,16:9) favoring panoramic crops, versus Casio’s 4:3 and 3:2 only.

Wildlife and Sports: Freeze Action and Track Subjects

Neither camera was designed for demanding wildlife or sports use, but burst shooting and autofocus speed give clues.

The Casio offers no specified continuous shooting, while the FujiFilm can manage a modest 2 fps burst at 12MP - still slow for action but better than standstill. Both utilize contrast-detection AF only, which lacks the predictive and tracking advantages phase detection brings.

In practical tests, locking focus on moving animals was hit-or-miss on both, though the FujiFilm’s touchscreen AF point selection allowed quicker manual adaptation. Neither can match modern cameras for fast-paced shooting, so serious wildlife or sports photographers will want to look elsewhere.

Street and Travel Photography: Discreteness Meets Usability

The Casio's diminutive dimensions and lightweight body make it ideal for street photography where discretion and spontaneity are prized. Quiet shutter, simple menus, and quick power-up times mean it blends in effortlessly, although the smaller screen can hinder quick composition.

Conversely, FujiFilm’s larger footprint and touchscreen may feel more obtrusive but better facilitate quick adjustments to exposure compensation, helping capture fleeting moments with precise control.

Regarding travel, battery life data is sparse for both, but given comparable internals and similar compact designs, expect moderate endurance requiring spare batteries on daylong excursions.

FujiFilm's 5x zoom spans telephoto needs, lending versatility for distant subjects, while Casio favors wide angles suited to landscapes and interiors.

Macro and Close-up Work: Getting Up Close

Macro capabilities are modest. Casio does not specify a macro focusing range, whereas FujiFilm promises focus as close as 9 cm. In practice, I found FujiFilm better able to capture small subjects with sharper focus and pleasing detail - academic for casual florals or tabletop shots.

Night and Astro Photography: Sensitivity and Stability

Low light shooting exposes sensor limits and stabilization impact.

Both contain sensor-shift image stabilization, crucial for minimizing blur in handheld shots at slower shutter speeds. The FujiFilm’s EXR sensor maintains a slight advantage in noise control at higher ISOs and includes relatively better max ISO setting (3200 boosted vs. Casio's 3200 max).

Neither supports RAW shooting, which limits post-processing in low-light conditions.

Video Capabilities: A Modest Offering

Both support 720p HD video, with the FujiFilm able to shoot 1280x720 at 30 fps while Casio caps at 20 fps for the same resolution.

Neither has microphone or headphone jacks nor manual audio controls, so videographers should temper expectations. Older Motion JPEG compression used by both limits practical editing.
