Casio EX-FS10 vs Sony Cyber-shot WX30: A Complete Real-World Comparison for Photography Enthusiasts

Choosing the right compact camera to fulfill your photography ambitions is a task fraught with options and technical nuances. Today, we put under the microscope two similarly priced, yet architecturally and technologically distinct cameras: the Casio EX-FS10 and the Sony Cyber-shot WX30. Each claimed its spotlight during the late 2000s to early 2010s, targeting ultracompact and small sensor compact market segments, respectively. Having extensively tested both cameras side-by-side across multiple photographic disciplines, I aim to bring you an immersive, technically informed, yet practical comparison to help you decide which is best suited to your needs.

First Impressions: Size, Handling, and Ergonomics

From the outset, these two cameras occupy somewhat different ergonomic niches, despite their shared compactness. The Casio EX-FS10, measuring 102 x 55 x 20 mm and weighing 121 grams, epitomizes the ultracompact ethos - slim, pocketable, and straightforward. Meanwhile, Sony's WX30 is a fraction smaller at 92 x 52 x 19 mm and slightly lighter at 117 grams, dipping more into the small sensor compact category with an inherently more versatile build.

Ergonomically, I found the WX30 better tailored for extended use. The grip and button placement allowed more intuitive shooting - especially important when chasing fleeting moments on the street or in nature. Its 3-inch touchscreen (with a commendable 922k-dot resolution) greatly improves framing and menu navigation over Casio’s 2.5-inch fixed LCD screen with 230k dots, which feels dated by comparison.

If portability and simplicity rank highest for you, the EX-FS10’s slim design is attractive. However, for photographers who value tactile feedback and flexible control, the WX30 provides a noticeably refined user experience.

Control Interface: How the Cameras Feel to Use

Delving deeper into controls, the Casio's minimal button layout mirrors its no-frills philosophy - lacking dedicated dials or toggles for shutter speed or aperture beyond an aperture priority mode, its manual controls are quite limited. In contrast, Sony's WX30 uses its BIONZ image processor to optimize settings automatically yet offers easier focus point selection with a 9-point AF array and a dedicated touch interface.

Notably, neither camera features manual exposure mode, meaning enthusiasts used to DSLR-like exposure control will find both models limiting. That said, if you prefer a camera primarily handling the technical heavy-lifting while you concentrate on composition, this yields a more relaxed shooting process.

Sensor, Image Quality, and Performance Under the Lens

Both cameras utilize a 1/2.3-inch sensor with identical physical dimensions (6.17 x 4.55 mm), but they diverge in sensor technology and resolution:

• Casio EX-FS10: 9 megapixels CMOS sensor
• Sony WX30: 16 megapixels BSI-CMOS sensor

The benefit of Sony’s Back-Side Illuminated (BSI) sensor technology is improved light-gathering efficiency, especially in low-light conditions. In practical testing, this translated into visibly cleaner images and more fine detail at higher ISOs, as well as greater dynamic range. Casio’s 9MP sensor, while adequate for casual snaps, struggles in shadow recovery and noise control especially above ISO 400.

The WX30’s higher native ISO ceiling (3200, compared to Casio’s 1600) combined with effective optical image stabilization also ensures better performance in indoor and dusk scenarios. The Casio’s lack of stabilization results in more motion blur unless you maintain faster shutter speeds or use a tripod to compensate.

Real-World Image Comparisons

In daylight portrait tests, faces rendered by the WX30 maintained excellent skin tone reproduction with softer roll-off in highlights, while the EX-FS10’s images occasionally exhibited slight overexposure and less color depth. Landscape shots from WX30 offered richer colors and better shadow detail, underlining its superior dynamic range and resolution for capturing intricate textures.

For telephoto reach, Casio’s 38-114 mm lens vs Sony’s longer 25-125 mm (35mm equivalent) focal length provides marginally better zoom range on Sony’s side, complemented by sharper corner performance and less chromatic aberration observed in my tests.

Autofocus and Burst Shooting: Keeping Pace with Your Subject

When shooting action - whether wildlife or sports - the AF system and shooting speed become critical.

I performed multiple tracking and burst tests, and it was clear the WX30 had the edge for rapidly capturing decisive moments - up to 10 frames per second burst allows it to capture quick sequences. Casio’s lack of continuous shooting and AF tracking makes it less suited for fast-paced photography like sports or wildlife.

However, both cameras lack sophisticated eye or face detection autofocus, which modern systems provide for enhanced portrait accuracy.

LCD and Live View Operation

The WX30’s 3-inch XtraFine TFT LCD with touchscreen capabilities offers a responsive and bright live view experience, with better color accuracy and visibility in outdoor light. The EX-FS10’s 2.5-inch fixed LCD appears quite dim in comparison and does not support touch input. The lack of an electronic viewfinder on both cameras is a drawback if you often shoot in bright sunlight but typical for their class.

Lens Quality and Optical Features

Both cameras have fixed zoom lenses with moderate zoom ranges, but optical specifications highlight some interesting contrasts:

• Casio EX-FS10: 38-114 mm equivalent, f/3.9-7.1
• Sony WX30: 25-125 mm equivalent, f/2.6-6.3, Optical Image Stabilization (OIS)

Sony’s WX30 benefits from a faster maximum aperture at the wide end (f/2.6), which enhances low-light capabilities and depth of field control, particularly in portraits and macro shots. Its longer zoom range combined with OIS optimizes image sharpness at telephoto positions better than Casio’s more basic zoom without stabilization.

Specialized Photography Disciplines

Let's explore how each camera performs in various photography genres to uncover their real-world strengths and limitations.

Portrait Photography

Portrait work demands pleasant skin tones, natural bokeh, and reliable focus on eyes or faces. Neither camera offers dedicated face or eye detection autofocus, which places a premium on manual framing and focusing skills.

• Casio EX-FS10: Wider aperture limited to f/3.9 at 38mm but rapidly closing to f/7.1 at the telephoto end restricts shallow depth-of-field effects.
• Sony WX30: F2.6 aperture at wide end offers superior subject isolation and nicer bokeh; 16MP sensor captures finer facial detail.

My tests showed Sony images yielding smoother tonal gradations and sharper eyes, which makes it better for casual portraits. That said, neither is ideal for professional portraiture given sensor size and lack of RAW support.

Landscape Photography

For landscapes, resolution, dynamic range, and weather sealing factor heavily.

• Resolution: WX30 (16MP) captures finer detail.
• Dynamic Range: WX30 BSI sensor holds shadows and highlights better, as confirmed by histogram analysis.
• Weatherproofing: Neither camera offers weather sealing or ruggedness features, limiting outdoor durability.

The WX30 is clearly the better landscape tool despite similar sensor size, but I doubt either can fully satisfy serious landscape photographers who want ultra-high resolution or rugged build.

Wildlife and Sports Photography

Here, fast autofocus, high frame rates, and reach matter most.

• Casio EX-FS10: No continuous AF, no burst mode - severely limiting for fast action.
• Sony WX30: Up to 10fps burst, 9-point AF + multi-area mode give it a clear edge.

For wildlife photographers on a budget, WX30’s superior reach, stabilization, and higher frame rates provide more opportunity to capture fleeting animal behavior.

Street Photography

Discretion, portability, and quick responsiveness are key here.

Both cameras are pocket-friendly and inconspicuous. I found the WX30’s touchscreen and faster AF system more reactive to spontaneous moments, and its quieter operation preferable.

EX-FS10’s limited controls and slower response make it less ideal for fast street shooting, but its slim profile can appeal if ultimate stealth is necessary.

Macro Photography

Macro requires short focusing distances and precise focusing.

• Casio EX-FS10: No declared macro focus distance.
• Sony WX30: 5 cm minimum focusing distance allows close-up shots.

In practice, WX30 delivers sharp, detailed macros thanks to better optics and focusing precision, which crowned it the better tool for insect or flower photography.

Night and Astro Photography

ISO performance, stabilization, and fast aperture contribute here.

• Casio EX-FS10: Max ISO 1600, no image stabilization.
• Sony WX30: Max ISO 3200, optical stabilization, and f/2.6 aperture.

During night tests, the WX30’s sensor and OIS enabled usable handheld shots under very low light with reduced noise. The Casio could only produce noisy images even when stabilized on a tripod for long exposures.

Still, both lack features like bulb mode or RAW support, limiting astrophotography potential.
