Casio EX-ZR800 vs Fujifilm FinePix S8100fd: A Small Sensor Superzoom Showdown

When it comes to small sensor superzoom cameras, the options might seem quite similar at first glance - fixed lenses, compact bodies, and a penchant for versatility. Yet, beneath the surface, design philosophies, imaging technologies, and user experiences diverge significantly. In this in-depth comparison, I put two noteworthy models through their paces: Casio’s EX-ZR800, launched in mid-2013, and Fujifilm’s FinePix S8100fd from early 2009. Both cameras target enthusiasts who want significant zoom reach wrapped in a compact form, but as we’ll see, they cater to distinct priorities and workflows.

Having personally tested hundreds of cameras under varied real-world conditions, my analysis blends rigorous technical assessment with practical usability insights. Whether you’re into portraiture, wildlife, landscape, or just need an agile “travel buddy,” this article dissects the strengths and compromises of each camera to help you find your best fit.

First Impressions: Size, Handling & Build Quality

Size and ergonomics dramatically affect how instinctive a camera feels in your hands over a long shoot. The Casio EX-ZR800 weighs a featherlight 222 grams and measures a sleek 108 x 60 x 31 mm - not the smallest compact but comfortably pocketable and easy to wield. In contrast, the Fujifilm S8100fd tips the scales at a hefty 405 grams with bulkier dimensions (111 x 78 x 79 mm), making it noticeably less portable but perhaps more versatile in feeling substantial and stable.

The EX-ZR800’s slim profile and lighter weight suit travelers and street photographers eager for stealth and convenience. The Fujifilm’s larger footprint, meanwhile, lends itself better to landscape or wildlife shooters who appreciate extra grip and steadiness, particularly with long telephoto lenses engaged.

In terms of build quality, neither camera boasts weather sealing or rugged environmental protection, so harsh outdoor conditions demand caution. Both bodies predominantly use durable plastics, but the Fujifilm feels fractionally more solid, thanks to its heft and bulkier construction. Still, neither would pass professional durability thresholds.

Control Layout & User Interface: Where Experience Meets Efficiency

Physical controls bridge intention and execution, especially on-the-go. Casio puts a clean, straightforward approach into the EX-ZR800’s design: it features logically placed buttons and dials but lacks backlit or illuminated keys. The fixed 3-inch Super Clear TFT LCD is sharp (922k dots), easy to read in good light, and effectively dominates the back panel. Contrast that with the Fujifilm S8100fd’s smaller 2.5-inch LCD with limited resolution (230k dots) - and an added electronic viewfinder that Casio omits completely.

The Fujifilm’s electronic viewfinder is a mixed blessing - while it allows for eye-level framing and stable shooting in bright conditions, the resolution and color accuracy feel outdated by today’s standards. Casio’s lack of a viewfinder means relying solely on the rear LCD, which, while generous and bright, may struggle in direct sunlight. I’ve found in bright field conditions that neither option outperforms a good optical viewfinder, but these features suffice for their class.

Control-wise, Casio’s EX-ZR800 offers manual exposure modes and aperture/shutter priority, but the physical manual focus control is somewhat underwhelming, suited for subtle adjustments rather than precision focusing. The Fujifilm, despite being older, offers solid manual focus operation and a dedicated single autofocus mode, though it lacks face detection.

Sensor Technology and Image Quality: The Heart of the Matter

Both cameras employ the same form factor sensor size - a 1/2.3-inch sensor measuring 6.17 x 4.55 mm, yielding a sensor area of roughly 28.07 mm². This size is characteristic of superzoom compacts and inherently limits image quality compared to larger sensors. Yet, the devil is in the details - sensor technology, resolution, and processing engines make all the difference.

Casio EX-ZR800:

• Sensor: 16 MP CMOS with anti-aliasing filter
• ISO range: 80–3200 (native)
• Processor: EXILIM Engine HS 3 - known for high-speed processing and noise reduction algorithms
• Raw support: No
• Dynamic range and color depth: Not officially DxO tested, but real-world results indicate decent color accuracy and tonal gradation

Fujifilm S8100fd:

• Sensor: 10 MP CCD with anti-aliasing filter
• ISO range: 64–6400 (native)
• Processor: Unspecified
• Raw support: No
• Dynamic range and color depth: Also not DxO tested; typical CCD rendition yields pleasing colors but struggles with noise at higher ISOs

From my extended hands-on testing, the EX-ZR800’s CMOS sensor coupled with its advanced EXILIM processor gives it an edge in low-light performance and dynamic range. The 16MP resolution facilitates slightly more detailed images, while noise control remains balanced up to ISO 1600, after which it softens detail moderately.

Conversely, the Fujifilm’s 10MP CCD sensor delivers characteristic punchy colors and smooth gradations at base ISO but noticeably falters above ISO 800. The CCD architecture, though excellent for color fidelity, is inherently noisier at high sensitivities.

Real-World Performance Across Photography Genres

Now to the crux - how do these cameras perform in actual shooting scenarios? I conducted extensive field trials covering portraits, landscapes, wildlife, sports, street, macro, night/astro, video, and travel photography, scoring each camera’s abilities in these demanding environments.

Portrait Photography: Capturing Skin Tones and Expression

Portrait photography demands accurate skin tones, pleasing bokeh, and responsive eye detection autofocus.

• Casio EX-ZR800: The 16MP sensor combined with face detection AF reliably locks on eyes, offering crisp details and natural skin rendering under varied lighting. Its F3.5–5.9 aperture range restricts bokeh creativity at longer focal lengths, but background blur remains adequate for casual portraits.

• Fujifilm S8100fd: Without face detection, autofocus relies on center-focused contrast detection. Skin tones reproduce warmly but occasionally lack subtle nuance. The faster lens range (F2.8–4.5) facilitates shallower depth of field, giving better subject-background separation.

In my experience, the Casio’s modern AF coupled with better LCD preview helped nail portraits quicker, while the Fujifilm required more manual input for focus precision. For casual portraits, the EX-ZR800 edges ahead thanks to more streamlined face detection.

Landscape Photography: Dynamic Range and Resolution Matter

Landscape demands wide dynamic range to preserve shadows and highlights, and high resolution to capture fine textures.

• The Casio’s 16MP CMOS sensor provides higher resolution files (4608 x 3456) compared to the Fujifilm’s 10MP (3648 x 2736), yielding more cropping flexibility and larger prints.

• Despite neither camera being weather sealed, which limits outdoor shooting in challenging conditions, Casio’s EXILIM processing delivers more balanced highlights and shadows, crucial for scenes with high contrast skies.

• Fujifilm’s lens is slightly longer at the tele end (486mm vs 450mm equivalent), but for landscape, the extra reach is less essential than edge sharpness and distortion control - the Casio appears slightly crisper at corners, according to pixel peeping.

Wildlife Photography: Autofocus Speed and Burst Shooting

For wildlife, autofocus responsiveness and continuous capture speed define the capability.

• Casio’s EX-ZR800 offers continuous shooting up to 3 fps and supports AF tracking with face detection, enabling moderate wildlife action capture.

• Fujifilm’s S8100fd lags at 1 fps continuous burst, with no tracking AF - making it challenging to maintain focus on sudden movements.

Neither camera targets professional wildlife shooters, but Casio’s faster buffer and AF tracking help when timing critical moments in the field.

Sports Photography: Frame Rates and Tracking Under Pressure

Sports photography demands rapid, accurate AF and higher frame rates.

• Casio pulls ahead with a maximum of 3 fps burst shooting and face detection-based AF tracking, though neither option is ideal for fast-paced sports - the lack of phase-detection AF limits speed and precision.

• Fujifilm’s single autofocus and 1 fps burst rate preclude serious action capture.

If your sport is casual family soccer games or kids’ activities, Casio will serve better. For serious action photographers, however, both cameras fall short.

Street Photography: Portability and Discretion

Street shooting demands compactness, quiet operation, and quick start-up.

• The Casio’s smaller size, lower weight, and quiet electronic shutter make it more suitable for candid street photography.

• The Fuji’s larger body and clicky zoom lens draw more attention, posing challenges for discreet shooting.

Without an electronic viewfinder to stabilize framing in bright sunlight, I found the Casio’s brighter fixed LCD indispensable for quick composition on the street.

Macro Photography: Close Focusing and Precision

Macro requires high magnification and fine focus control.

• The Fujifilm’s ability to focus down to 1 cm gives it a distinct advantage for close-up detail work over the Casio's 4 cm minimum.

• Casio’s sensor-shift image stabilization helps here by minimizing blur from hand shake.

If you prioritize macro capabilities within a superzoom compact, the Fujifilm’s aggressive close focus point makes it a better tool despite its heavier body.

Night and Astro Photography: ISO and Exposure Handling

Night shooting tests the limits of sensor noise and long exposure control.

• Casio’s native ISO up to 3200 and exposure flexibility (up to 2000 seconds shutter) permit more experimentation.

• Fujifilm peaks at ISO 6400 but with noisier CCD output; shutter speed tops out similarly.

In practical night shots, Casio’s CMOS sensor noise control and built-in sensor-shift stabilization yield cleaner, sharper astro images after 30+ seconds exposures - important in low light narrative photography.

Video Capabilities: Resolution and Stabilization

Both cameras offer video, but in different leagues.

• Casio captures Full HD 1080p at 30 fps with decent MPEG-4/H.264 compression, making it suitable for casual video.

• Fujifilm tops out at VGA 640 x 480 resolution, quite modest by today’s standards.

Neither camera has microphone/headphone jacks, limiting audio recording control. The Casio’s sensor-shift stabilization helps smooth handheld video, an advantage over the Fuji.

Travel Photography: Versatility and Battery Life

A solid travel camera balances image quality, zoom reach, and operational endurance.

• Casio’s small body, moderate zoom (25-450 mm), and commendable 470 shot battery life make it a solid travel companion.

• Fujifilm’s longer zoom reach (27-486 mm) is appealing, but heavier body and unknown battery life (relying on AA cells) can be inconvenient.

The Casio’s SD card storage, USB 2.0, and HDMI output ease workflow on the road.

Professional Use: Reliability and Workflow Integration

Neither camera targets professional workflows, but some considerations stand out.

• Both lack RAW support, a significant drawback for professional image control.

• Casio’s modern EXILIM processing aids JPEG quality; Fujifilm’s older files have less editing latitude.

• Both cameras lack advanced connectivity (no WiFi, Bluetooth, or GPS) and rugged environmental sealing.

For pro backup or quick shooting, Casio offers a more up-to-date interface and file quality, but dedicated professional shooters will want more robust systems.
