When evaluating compact cameras that aim to provide a balance between portability and zoom versatility, the Casio EX-Z90 and Fujifilm FinePix SL240 emerge as intriguing contenders, albeit from slightly different design philosophies and release periods (2009 for Casio vs. 2012 for Fujifilm). Both leverage 1/2.3-inch CCD sensors yet serve different user profiles with their unique features and ergonomics.

As a veteran camera reviewer who has extensively handled thousands of cameras across multiple genres, I present an exhaustive comparative analysis of these two models to help both enthusiasts and professionals understand their strengths, weaknesses, and suitability across photographic disciplines.

First Impressions: Size, Ergonomics, and Handling

Compact vs. Bridge: Physical Form Factor and Controls

The Casio EX-Z90 is a pure compact camera designed for ultimate portability. Its sleek, minimalist body measures just 90x52x19 mm and weighs a featherlight 121 grams, exemplifying pocketable convenience. In contrast, the Fujifilm SL240 embraces a bridge camera form factor, resembling a DSLR in size and grip, measuring 122x93x100 mm and tipping the scales at 510 grams.

This size disparity extends beyond mere dimensions - it significantly affects handling and user experience. The EX-Z90’s petite frame offers limited tactile control but excels in quick grab-and-go scenarios, ideal for street photographers or travelers prioritizing compactness. On the other hand, the SL240 provides an SLR-like grip, multiple physical controls (shutter priority, aperture priority, manual exposure modes), and expands operational versatility at the expense of bulk.

The top view comparison reinforces this notion: the Fujifilm features a thoughtfully laid-out control dial, dedicated exposure compensation, and a built-in electronic viewfinder (EVF), elements absent on the Casio.

This layout speaks volumes about the SL240’s ambitions to cater towards enthusiasts craving manual inputs, whereas the EX-Z90 focuses on simplicity.

Imaging Core and Sensor Capabilities

Sensor Specifications and Image Quality Metrics

Despite both cameras employing the common 1/2.3-inch CCD sensor format - measuring 6.17 x 4.55 mm - the Fujifilm SL240 edges the Casio EX-Z90 in sensor resolution, featuring a 14-megapixel sensor versus 12 megapixels on the Casio. While neither supports RAW image capture, both are limited to JPEG output, constraining professional post-production flexibility.

The CCD sensor technology scelta by both models inherently favors color fidelity and shadow detail for their generation, but at this size, noise performance beyond ISO 400 suffers notably, which limits night shooting capabilities. The SL240 extends ISO capability to 6400 (boosted), whereas the EX-Z90 caps at 1600 native ISO with no extended modes, reflecting the SL240’s marginal advantage in low-light adaptability.

It is important to recognize that while sensor resolution counts here, the pixel pitch remains relatively tight on both, compromising on dynamic range and low-light flair compared to larger-sensor cameras.

Display and Viewfinder Utility

LCD Screen and Interface Comparison

The Casio EX-Z90 is outfitted with a 2.7-inch fixed LCD display at a modest 230k-dot resolution, sufficient but uninspiring by modern standards. The Fujifilm SL240 considerably upgrades this experience with a 3.0-inch TFT LCD at a crisp 460k-dot resolution, delivering better clarity, color accuracy, and framing precision.

Furthermore, the SL240 compensates for its larger body by providing a built-in electronic viewfinder covering 97% of the frame. This significantly aids composition under bright sunlight or when stability is crucial, a feature entirely missing on the minimalist Casio.

For photographers who require flexible viewpoint options, such as wildlife or sports shooters who need quick eye-level framing, the SL240 offers an unmistakable advantage.

Lens and Zoom Reach: Versatility for Different Disciplines

Focal Length Range and Aperture Dynamics

In the realm of focal length and zoom capability - the defining trait for many enthusiast compacts - the Fujifilm SL240 dramatically surpasses the Casio EX-Z90. The SL240 boasts a staggering 24–576 mm equivalent (24× optical zoom), which enables extreme telephoto reach, supported by sensor-shift image stabilization to mitigate handshake at long zooms.

In comparison, the EX-Z90 provides a much more modest 35–105 mm equivalent range (3× zoom), limiting its use predominantly to portraits and moderate telephoto needs.

Taken together, the zoom difference strongly delineates their use cases: the SL240 is tailored for wildlife, sports, and landscape photographers who need extensive reach, while the EX-Z90 suits casual portraits, street photography, and travel snapshots where ultra-compactness reigns supreme.

Autofocus System and Burst Shooting: Responsiveness in the Field

Speed, Accuracy, and Tracking Ability

Autofocus systems markedly influence user experience, especially for fast-moving subjects or dynamic scenes. The EX-Z90 relies on contrast-detection AF with a single center autofocus point - a simple system adequate for static subjects but limited for continuous focusing or tracking moving objects. Moreover, it lacks continuous autofocus and face detection, diminishing its utility for unpredictable scenes like sports.

Conversely, the SL240 incorporates continuous autofocus with tracking capabilities and multiple AF areas alongside face detection, bolstering its performance for mid-speed action and portraiture. Such an AF system is especially useful for amateur wildlife and event photographers, who must rely on consistent lock-on.

Regarding continuous shooting performance, the SL240 offers only 1 fps burst rate, which restricts its suitability for sports photography where faster frame rates are prized. The EX-Z90 doesn’t specify burst capabilities, indicating a likely similar or slower pace.

Exposure Modes and Creative Control

Manual Settings and Exposure Compensation

One area where the Fujifilm SL240 distinctly trumps the Casio EX-Z90 is in exposure control. The SL240 supports shutter priority, aperture priority, and full manual exposure, empowering photographers to tailor settings meticulously to creative intent. Adjustable exposure compensation and bracketing features further expand flexibility, especially in challenging lighting.

The Casio EX-Z90, by contrast, is essentially a point-and-shoot with no manual exposure options, no shutter/aperture priority modes, or bracketing functions. Its operation revolves around fully automatic exposure and a few scene modes, optimal for novices or spontaneous shooting but limiting for those who desire precise creative input.

For photography practitioners accustomed to controlling depth of field, motion blur, or dynamic exposure bracketing, the SL240’s feature set is unarguably the preferable choice.

Build Quality and Environmental Resistance

Both cameras unfortunately lack weather sealing - no waterproofing, dustproofing, shockproofing, or freezeproof capabilities - restricting usage in adverse outdoors scenarios without additional protection.

Build-wise, the EX-Z90’s compact plastic housing emphasizes portability, but at the expense of durability and grip. The SL240, while bulkier, offers a more robust grip-enhanced chassis, providing greater handling confidence, particularly during extended sessions or telephoto use.

Battery Life and Storage Solutions

The Fujifilm SL240 uses the NP-85 battery pack, rated for approximately 300 shots per charge, which is decent for its class. The Casio EX-Z90 employs a more diminutive NP-60 battery but lacks official battery life ratings, though field tests suggest a shorter lifespan due to smaller capacity and power consumption profiles.

Storage-wise, both cameras utilize SD card media; the SL240 supports SDXC cards, allowing higher capacity, while the EX-Z90 is limited to SD/SDHC cards and additionally offers internal memory - a feature that may appeal for emergency storage but is typically insufficient for serious photography.

Video Capabilities: Recording and Formats

The Fujifilm SL240 supports 720p video at 30 fps with H.264 compression, producing comparatively efficient files with reasonable quality. It also offers a 640x480 30 fps mode and the older Motion JPEG format. However, the SL240 lacks microphone and headphone jacks, precluding professional audio capture or monitoring.

The Casio EX-Z90 offers only up to 720p at 24 fps in Motion JPEG format, generally resulting in larger file sizes and lower compression efficiency. Its video functionalities are basic, catering primarily to casual video capture rather than semiprofessional production.

Neither camera supports 4K video or in-body movie stabilization, where competitors in recent years have made strides.
