Casio EX-10 vs. Fujifilm A100: A Deep Dive Into Two Small Sensor Compacts

Choosing the right compact camera in today’s fast-evolving photographic landscape can be a challenge, especially when comparing models from different eras and manufacturers. Having spent over 15 years rigorously testing digital cameras across genres, I’m excited to place the Casio EX-10 and Fujifilm FinePix A100 head-to-head. Both small sensor compacts target casual photographers looking for portability coupled with respectable image quality, but they are separated by a four-year gap and distinct design philosophies.

In this article, I’ll take you through everything from sensor performance to ergonomics, practical shooting experiences to video capabilities, and ultimately help you decide which - if either - is right for your photographic style. This comparison relies on both meticulous lab testing at my studio and extensive field use across multiple photography genres including travel, portraiture, and macro. Let’s get started.

Size and Handling: Which Compact Feels Better in Your Hands?

When it comes to daily carry cameras, size and ergonomics can make or break your shooting experience. The Casio EX-10 and Fujifilm A100 are both “pocketable” compact cameras, but their physical designs yield very different user impressions.

The Casio EX-10’s dimensions (120 x 68 x 49 mm) and weight (384 g) place it in the heftier side of compacts, but I find this larger footprint lends a sense of stability and confidence when shooting. Its body feels solid, and the textured grip is comfortable for longer sessions - an important factor during travel or outdoor shoots. Meanwhile, the Fujifilm A100 is noticeably smaller (92 x 61 x 22 mm) and ultra-lightweight at just 124 grams. This makes it incredibly pocket-friendly and discreet for street photographers looking for minimal intrusion.

However, the trade-off with the A100’s compactness is a plasticky build and less ergonomic grip. Over long periods, my hands would fatigue, and the smaller size resulted in less control precision. The EX-10, although larger, incorporates better button placement which I’ll detail more when discussing its user interface.

Design and Controls: Layout That Makes a Difference

Diving under the hood of user experience, I examined the control layouts, top panel design, and the feedback of physical buttons on both cameras.

The EX-10 sports a smart control arrangement, including clearly labeled buttons and dials for exposure compensation, ISO, and manual mode toggling. Its tilting, touchscreen LCD (covered later) also makes changing settings instinctive. I especially appreciate the inclusion of manual focus modes and shutter/aperture priority options - functions missing on the A100 - which give photographers creative flexibility.

In contrast, the Fujifilm A100 employs a much more stripped-down interface with minimal buttons and no menu shortcut buttons. It lacks manual exposure modes entirely, relying on a fully automatic setup. While this simplicity may suit absolute beginners, I quickly found the absence of tactile control limiting for more deliberate shooting.

Sensor and Image Quality: The Heart of the Matter

An area where absolute fundamentals are configured: sensor size, resolution, and resulting image quality.

Both devices share a small sensor form factor but differ notably:

• Casio EX-10: 1/1.7" CMOS sensor, 12 MP resolution (4000 x 3000 px), native ISO 80–12800, RAW support included.
• Fujifilm A100: 1/2.3" CCD sensor, 10 MP resolution (3648 x 2736 px), native ISO 100–1600, no RAW support.

My controlled tests at base ISO reveal the EX-10’s 1/1.7" sensor produces sharper, cleaner images with superior dynamic range (especially visible in bright-to-shadow transitions) compared to the smaller CCD sensor in the A100. The EX-10’s CMOS sensor performs far better under low light, delivering usable images up to ISO 3200 with less noise.

Fujifilm’s CCD sensor tends to struggle at anything beyond base ISO, with noise and soft details degrading images quickly. The lack of RAW also hinders flexibility in post-processing, especially for enthusiasts who like to fine-tune exposure and color.

Display and Interface: Your Window to the Image

The rear screen often dictates your shooting confidence, framing ease, and overall navigation comfort.

Here, the Casio’s 3.5-inch Super Clear LCD with 180-degree upward tilt touchscreen shines. This articulating screen proves invaluable for composing low- or high-angle shots, self-portraits (though no front-facing cam support), and quick menu changes via tap. The screen resolution of 922k dots provides a vivid view of your subject and settings, perfect for on-the-fly adjustments.

The Fuji A100, by contrast, features a smaller 2.7-inch fixed screen at 230k dots - noticeably dimmer and harder to see in bright daylight. The lack of touch support and fixed angle limits composition flexibility and slows down navigation through menus. For street and travel photography, this becomes frustrating quickly.

Autofocus and Burst Shooting: Catching the Moment

Autofocus speed and accuracy are mission-critical for genres such as sports, wildlife, and candid street photography.

The Casio EX-10 offers contrast-detection autofocus with face detection and continuous tracking, and a healthy burst rate of 10 fps, excellent for capturing fleeting expressions and action scenes. The touchscreen focus point selection further accelerates precision focus placement.

The Fuji A100 employs basic single-shot contrast-detection AF with a limited number of focus points and no face detection. Continuous shooting modes are absent, making it less suited to moving subjects and spontaneous moments.

In my field tests during a local 5K run, the Casio reliably tracked runners with decent margin of error. The Fujifilm struggled to lock focus quickly enough, resulting in missed or blurred frames.

Lens Performance: Versatility and Creative Control

Very few compact cameras allow lens changes, so zoom range and aperture quality determine the creativity you can express.

The Casio EX-10's fixed 28–112 mm equivalent (4x zoom) f/1.8 to f/2.5 aperture is impressively bright for a compact lens, performing admirably in low light and providing pleasant background blur at the telephoto end. Its macro focusing capability at just 1cm produces superb details close-up, perfect for macro shooters who want a pocketable solution without sacrificing sharpness.

The Fujifilm A100 sports a 36–107 mm equivalent lens with slower aperture values of f/3.1 to f/5.6, which limits light intake and depth of field control. Its macro limit at 5cm is decent but less versatile. The smaller zoom range restricts framing options slightly.

In practice, I found the Casio’s lens gave me more creative options for portraits and landscapes, particularly with bokeh and isolated subjects thanks to the wide apertures.

Video Capabilities: Shooting Beyond Stills

Modern photographers often want hybrid performance including video. How do these two cameras stack up?

Casio supports Full HD 1080p video at 30 fps, encoded in MPEG-4 H.264, with a built-in electronic image stabilization system that smooths handheld recording effectively. While there’s no external microphone input, the video is sharp and color-accurate in daylight conditions.

The Fujifilm A100 records only VGA-quality (640x480) at 30 fps in Motion JPEG format, which feels dated and noisy by today’s standards. No video stabilization is included.

If you intend to shoot casual HD videos or quick travel clips, the Casio EX-10 significantly outperforms the A100.

Battery Life and Storage: How Long and How Much?

Battery life plays a pivotal role during long outings and travel photography when charging isn’t always feasible.

The EX-10 uses a Li-ion Battery Pack (Li-130A) rated for 455 shots per charge, which is fairly respectable considering its advanced features. Additionally, it supports large SD/SDHC/SDXC cards, giving you ample storage capacity for RAW files and HD video.

The A100’s battery specs are not explicitly listed, but it utilizes less powerful internal options typically offering fewer shots due to older technology and fixed lens design. Storage options include SD cards and limited internal memory.

For photographers on extended excursions, the EX-10’s battery stamina and storage flexibility provide peace of mind.

Weather Sealing and Durability: Shooting in the Elements

Neither camera offers formal weather sealing, waterproofing, or robustness ratings. If you plan to shoot in harsh environments frequently, these models may require complementary protection gear.

Real-World Shooting Across Genres

To help you visualize what each camera brings to the field, I applied both to a wide range of photographic genres:

Portraits

The EX-10’s wide aperture lens and face detection AF delivered beautiful skin tones and creamy bokeh backgrounds, even when handheld in ambient light. Images appear natural with balanced contrast and excellent detail. Fuji A100 was more limited in low light and flat AF performance, resulting in softer images.

Landscapes

With higher resolution and better dynamic range, Casio accurately captured intricate textures in scenes ranging from mountains to urban skylines. The articulated screen aided composition near ground level. The Fuji’s smaller sensor constrained sharpness and dynamic range, producing flatter scenes.

Wildlife

Neither camera is truly designed for fast wildlife photography, but EX-10’s rapid burst mode and face tracking offered better success capturing pets or birds in open settings compared to the slower Fuji autofocus.

Sports

The EX-10 again displayed advantages in burst shooting and AF tracking but could only scratch the surface given its compact sensor and limited telephoto reach. The Fuji did not offer burst mode, greatly restricting sports use.

Street Photography

The smaller size and discreteness of the Fuji A100 are beneficial here for stealth, but slow autofocus and menu navigation hamper rapid shooting. The EX-10 is bulkier but rewards with reliability.

Macro

EX-10’s 1cm close focusing and sensor-shift stabilization made macro images rich and sharp. Fuji’s 5cm minimum distance and no stabilization yielded less detailed shots.

Night/Astro

The EX-10’s ISO range and image stabilization offer basic starry sky captures and night scenes. The Fuji’s limited sensitivity renders nighttime shots grainy and unusable beyond basic snapshots.

Video

Only EX-10 can deliver crisp 1080p recordings suitable for casual video.

Travel

The EX-10’s balance between advanced controls, image quality, and portability give it the edge over the smaller but more simplistic Fuji A100 in travel photography.

Professional Use

Neither is a professional-level tool, but the EX-10’s RAW support, manual controls, and more robust features make it a better option for enthusiasts seeking a serious compact.
