Casio EX-Z800 vs Fujifilm FinePix SL240: A Hands-On Comparison for the Discerning Photographer

When diving into the realm of compact and bridge cameras, the Casio EX-Z800 and the Fujifilm FinePix SL240 often come up as contenders for users who want more than smartphone snaps but aren’t ready to dive fully into high-end DSLRs or mirrorless systems. Both brought interesting features to the table during their respective releases, catering to enthusiasts looking for affordability coupled with versatility. Having tested these two extensively in controlled environments and real-world shooting situations, I want to share a detailed comparison that will cut through the specs and marketing speak to help you decide which fits your photography style best.

Size and ergonomics are fundamental - here’s how these two stack up physically.

Form Factor and Handling: Compact vs. Bridge Style

Right off the bat, the Casio EX-Z800 appeals to those who prize portability. This ultracompact camera weighs just 124 grams and measures a trim 91x52x20 mm, fitting snugly in a pocket or small bag. It’s a no-fuss shooter designed with casual photographers or travelers who want something lightweight. However, the small body means the grip is minimal, and control dials are largely absent, which may frustrate those who like tactile feedback and quick adjustments.

On the other side, the Fuji SL240, tipping the scales at 510 grams and sporting an SLR-like bridge design (122x93x100 mm), feels much more substantial and robust in hand. The ergonomics cater to users who prefer a DSLR-style feel - deep grips, a pronounced shutter button, and an electronic viewfinder (albeit not very high resolution). Its larger body lends itself better to extended shooting sessions, especially at longer focal lengths where stability is paramount.

Notice Fuji’s traditional camera styling with more buttons and dials versus Casio’s minimalism.

In day-to-day handling, I found the Fujifilm far easier to hold steady for telephoto shots thanks to the added heft and grip contours. You’ll appreciate this if you plan on shooting wildlife or distant subjects. But if you’re after an everyday grab-and-go camera, Casio's compact form is undeniably convenient.

Sensor and Image Quality: The Heart of the Matter

Both cameras are equipped with a 1/2.3” type CCD sensor at roughly 14 megapixels - quite typical for cameras in these classes during their respective release periods. The sensor area (about 28.07 mm²) and pixel count suggest similar baseline potential for image detail.

Sensor dimensions and resolution help explain image quality and performance expectations.

That said, the Fujifilm edges ahead by offering a wider ISO range (up to ISO 1600 natively, boostable to ISO 6400), whereas Casio caps at ISO 3200 without boosts. In practical terms, Fujifilm’s higher ISO support translates to cleaner shots in challenging low-light situations, although noise is still evident beyond ISO 800–1600. Casio’s noise rises faster, limiting its usability in dim environments.

The maximum image resolutions are close - 4320x3240 for Casio versus 4288x3216 for Fuji - so pixel-peepers will get nearly equivalent raw pixel counts (though neither camera supports RAW output, which is a downside for serious photographers wanting post-processing flexibility).

In tests comparing color rendition, the Fujifilm produced more neutral tones with better skin tone accuracy, a product of more sophisticated image processing electronics and slight color science refinement. The Casio’s results tend to be a bit punchier but sometimes oversaturated, especially reds. Both apply an anti-aliasing filter, which slightly smooths fine detail.

Viewing and Interface: See What You Capture

The rear design and viewfinder options illustrate the cameras' different philosophies. The Casio EX-Z800 features a modest 2.7-inch fixed LCD with a resolution of only 230k dots. The screen brightness and viewing angles are just average, making composition in bright daylight somewhat challenging.

Meanwhile, the Fujifilm SL240 steps up with a 3-inch TFT color LCD boasting twice the resolution at 460k dots. This screen is brighter, sharper, and more responsive, facilitating easier framing and review of shots. Plus, the SL240 includes a 97%-coverage electronic viewfinder, absent in the Casio. Although it’s not a top-tier EVF, it does provide better visibility in out-in-the-sun scenarios and offers a traditional eye-level shooting experience beloved by many.

The Fuji’s bigger, sharper screen and electronic viewfinder offer more framing options than Casio’s small LCD.

Operating the controls is smoother on the Fujifilm due to dedicated buttons for exposure modes, flash, and ISO, as well as a traditional mode dial. Casio’s menu-centric interface requires more digging for settings changes. Ergonomically, the Fuji caters more to users who value quick access to manual adjustments.

Lens Capacity and Zoom Versatility

Evaluating the lenses, both models have fixed zooms but vastly different zoom ranges and apertures. The Casio covers a focal range of 27-108mm (4x optical zoom, equivalent on full frame), with apertures from f/3.2 at wide angle to f/5.9 at telephoto.

The Fujifilm, however, walks away the winner in this category with an astonishing 24-576mm equivalent focal range - a 24x optical zoom that caters to everything from wide landscapes to distant wildlife. The aperture varies from f/3.1 to f/5.9, similar on the limits but with far greater reach.

This difference drastically impacts photography style. The Casio falls into an easy everyday zoom range good for street photography, casual portraits, and snapshots without requiring significant physical movement.

The Fujifilm, with its superzoom lens, is far more versatile for outdoor adventures, such as wildlife and sports photography where telephoto reach is king. This wide focal range reduces the need to carry multiple lenses or step away from your subject.

Autofocus and Shooting Performance

Here we get to a domain that’s crucial in fast-paced photography: autofocus and shooting speed.

• Casio EX-Z800 employs a simple contrast-detect autofocus system with no face or eye detection. It offers single AF mode only - meaning it locks focus when you half-press the shutter but doesn’t track moving subjects. That limitation narrows its practical use if you want to shoot events, action sports, or wildlife.

• Fujifilm SL240 integrates a contrast-detect system as well, but adds autofocus tracking with continuous AF capabilities and face detection. This is a big advantage for dynamic subject photography, where locking focus once isn’t sufficient.

Continuous shooting speeds also differ: Casio doesn’t advertise a burst mode, effectively limiting continuous shooting. Fuji offers a modest 1 fps burst with continuous AF, which although slow by DSLR standards, provides some utility in capturing fleeting moments.

My hands-on tests show the Fuji produces sharper captures of moving subjects, confirming the practical benefit of AF tracking. Casio, on the other hand, requires more patience and skillful timing.

Built-In Flash and Stabilization

Both cameras come equipped with sensor-shift image stabilization, which is helpful given their small sensors and relatively slow wide-open apertures. This feature mitigates camera shake during handheld shooting at longer focal lengths or dim conditions.

Flash units differ slightly: Casio’s built-in flash supports basic modes - auto, flash on/off, and red-eye reduction - without specifying range.

The Fujifilm’s flash is rated to 7 meters and offers more flexible modes, including slow-sync, which is excellent for balancing ambient and flash light in portraits or night scenes. It even supports external flash units via a hot shoe, something Casio does not.

Video Capabilities: Casual Clips or Serious Productions?

Video is no longer an afterthought, even in compact cameras. Casio EX-Z800 records HD video at 1280x720 pixels but only at 20 fps, resulting in somewhat choppier footage. It records Motion JPEG format, which means larger file sizes and less efficient compression.

Fujifilm SL240 captures 720p HD video at a smoother 30 fps and offers both H.264 and Motion JPEG encoding. This gives significantly better quality for casual video and more efficient storage. Additionally, the SL240 supports HDMI output, enabling easy playback on HDTVs - something missing from the Casio.

Neither camera supports microphone or headphone inputs, so audio monitoring and quality are basic.

Battery Life and Storage Considerations

Battery endurance is a vital practical consideration. Fuji estimates a healthy 300 shots per charge using its NP-85 battery pack, which aligns with my testing especially when using the electronic viewfinder conservatively.

Casio’s battery life is unspecified but based on experience with similar ultracompacts, expect around 150-200 shots on the NP-120 battery under normal conditions - less if you frequently use the LCD or flash.

Both cameras use standard SD/SDHC cards, with Fujifilm adding SDXC support for higher capacity cards - important if you plan longer shoots or substantial video recording.

Real-World Performance Across Photography Genres

Let me break down where each camera best suits various photographic disciplines, drawing on my extensive testing sessions.

Portrait Photography

• Fujifilm SL240 benefits from face detection autofocus and better color reproduction, producing natural skin tones and respectable background blur at the longer telephoto end.

• Casio EX-Z800 lacks face detection and manual exposure modes, hindering precise portrait control. Its narrower zoom range limits creative framing, and color tends more toward punchy, less natural hues.

Landscape Photography

• Sharpness at the wide end is respectable on both, but the Fuji’s longer zoom offers more compositional options.

• Casio’s small size and light weight make it subtly excellent for candid street shooting and travel, easily slipping into pockets and ready for quick snaps.

• Fuji’s bulkier build and longer lens require a dedicated bag, making it less inconspicuous but offering more framing flexibility.

Macro Photography

• Fujifilm’s 2cm minimum focus distance works well for close-up shots, whereas Casio lacks a specified macro mode or dedicated close focus range, limiting its use here.

Night / Astro Photography

• Low light performance is modest in both, but Fuji’s higher ISO ceiling and slower minimum shutter speed edge it ahead for night shots.

• Neither supports long exposure modes or interval timers for astrophotography enthusiasts.

Video Production

• Fujifilm produces smoother, better compressed HD video, including HDMI output. It’s your better option for casual video recording.

• Casio’s limited frame rate and file format make video more basic and less practical for polished recordings.

Professional Usage

• Neither camera supports RAW files or advanced custom controls expected by professional photographers.

• Workflows relying on flexible, high-quality files would find both lacking.

Technical Insights: What Sets These Cameras Apart Architecturally?

• Both cameras use CCD sensors coupled with sensor-shift stabilization, but Fuji incorporates more sophisticated autofocus algorithms and manual exposure modes (shutter/aperture priority, manual), giving greater creative control.

• The Casio’s processor, the Exilim Engine 5.0, is competent but older and paired with fewer hardware bells and whistles.

• Fujifilm’s inclusion of an electronic viewfinder, HDMI output, and expanded ISO range reflect a more advanced feature set targeting enthusiast photographers.
