Casio EX-H15 vs Pentax WG-10: A Practical Comparison of Two Compact 14MP Cameras

In the world of compact cameras, the Casio EX-H15 and Pentax WG-10 offer intriguing, yet fundamentally different takes on the small-sensor concept. Both pack 14-megapixel CCD sensors with similar resolutions, but diverge sharply in design philosophy, ruggedness, and user experience. Having tested both extensively in diverse settings - from urban streets to backyard wildlife shoots - I’m here to unpack their core strengths and weaknesses and help you choose the right compact for your photographic pursuits.

Let’s start by placing these two contenders side by side to get a feel for their physicality and layout:

First Impressions: Design and Handling

Casio EX-H15: Launched in early 2010, the EX-H15 is a classic pocket-friendly compact aimed at casual users. It boasts a modest 101x60x28mm footprint and weighs a featherlight 161 grams. The lens offering a versatile 24-240mm equivalent zoom range (10x optical zoom) suggests an all-purpose intent, from wide-angle snapshots to telephoto close-ups. The fixed 3-inch, fixed-type LCD lacks touchscreen function but offers decent 461k-dot resolution, which was competitive at its release.

Pentax WG-10: The WG-10 entered the scene mid-2013 targeting adventure seekers and outdoor shooters. Slightly chunkier at 116x59x29mm and 167 grams, it is engineered for durability - boasting full waterproofing (up to 10 meters), dustproofing, shockproofing from 1.5m drops, crushproof capacity, and freezeproof down to -10°C. Alongside a more modest 28-140mm equivalent zoom (5x zoom), its rugged credentials make it compelling for travel, hiking, and active lifestyles that demand a tough companion.

The control layout shows subtle evolution in ergonomics:

The Casio's controls are pared-back, emphasizing compactness over extensive direct access. Pentax, conversely, integrates slightly larger buttons and tactile feedback optimized for use with gloves or wet hands, typical for its rugged category.

Sensor and Image Quality Insight

Both cameras feature the same sensor size: 1/2.3” CCD (6.17 x 4.55 mm), and roughly 14 megapixels. That means their fundamental light-gathering capability and diffraction limits are very similar.

Sensor Technology: The use of CCD sensors in both models means excellent color rendition and low noise at base ISOs, but a relative shortfall in high ISO noise suppression compared to modern CMOS sensors. CCD's strength lies in controlled color output and rich tonal transitions, making these cameras suitable for daylight shooting and controlled environments.

Resolution: Around 14MP yields detailed images suitable for 8”x10” prints and web use without significant cropping. The Casio slightly edges out in max resolution (4320x3240 vs. 4288x3216) but practically this difference is negligible.

ISO Range: Casio's base ISO starts at 64 with a ceiling at 3200 ISO, while Pentax opens at 125 and extends to ISO 6400 - though we should temper expectations for high ISO usability given sensor type and age. In tests under low light and high ISO, both introduce noticeable noise beyond 800 ISO with the Pentax showing slight advantage at its max ISO 6400 but with significant grain.

Viewing and Interface: LCD and EVF

Neither camera includes an electronic viewfinder, relying solely on LCDs:

The Casio sports a higher resolution 3.0" display, which aids in critical focusing and image review. The lack of touchscreen places more importance on physical buttons for navigation.

The Pentax opts for a smaller 2.7" screen with lower resolution (230k dots) but adds an anti-reflective coating for better visibility outdoors in bright conditions - essential for adventure use.

From a usability standpoint, the Casio’s larger, sharper LCD is comfortable for urban and indoor shooting while Pentax’s outdoor-oriented screen is far superior if shooting in harsh natural light environments.

Autofocus and Shooting Performance

Autofocus configurations underline the disparate philosophies:

• Casio EX-H15 relies on a simple contrast-detection AF system with single-point focus only and no face or tracking detection.
• Pentax WG-10 adds a rudimentary tracking autofocus with 9 focus points and face detection - remarkable for a compact in this class and era.

The WG-10's focus tracking, particularly for moving subjects, comes as a thoughtful boon for outdoor and wildlife shooters who can’t always stop and compose methodically. However, burst mode on the Pentax is sluggish at 0.7 fps, not leaving much room for high-speed action sequences.

Shutter speed ceilings differ - 1/2000s max on Casio versus 1/4000s on Pentax - the faster shutter on the WG-10 offers more creative control in bright conditions or action.

Lens Quality and Macro Capabilities

• Casio’s 24-240mm F3.2-5.7 lens provides a versatile focal range - excellent for travel and street photography where you may encounter varied scenes.
• Pentax’s 28-140mm lens is more limited zoom-wise but counters with macro focusing as close as 1 cm, enabling dramatic close-ups of small subjects, an advantage for nature enthusiasts.

Despite the smaller zoom, the Pentax demonstrates relatively less distortion and chromatic aberration at wide apertures thanks to quality lens coatings and rugged barrel architecture.

Image Stabilization and Flash

Both cameras use sensor-shift image stabilization, critical for handheld shooting at longer focal lengths. In real-world testing, the Casio shows competent shake reduction up to 1/15s at 240mm equivalent, while the Pentax offers a slight improvement given its optimization for motion and underwater shooting.

Flash capabilities differ slightly:

• Casio’s internal flash includes standard modes: Auto, On, Off, Red-eye reduction.
• Pentax adds a Soft flash mode and can fire with a flash range up to 1.2 meters.

Neither supports external lighting - understandable for their compact, adventure-focused categories.

Video Recording Capabilities

Looking at video, the Pentax pushes farther:

• Casio shoots 720p at 30 fps using Motion JPEG codec - file sizes are large and less suitable for complex editing.
• Pentax offers 720p at 60 and 30 fps with MPEG-4/H.264 compression - a modern codec that conserves space and offers smoother motion playback.

Neither camera supports higher resolutions like Full HD or 4K - reflecting their generation and design focus.

Ruggedness and Weather Sealing

The exclusion or inclusion of weather sealing is a dealbreaker depending on your use case:

• Casio EX-H15: no sealing, standard compact sensitive to moisture, dust, and impact.
• Pentax WG-10: fully waterproof (up to 10m), dustproof, shockproof, crushproof, and freezeproof.

For outdoor, underwater, or harsh environment users, the Pentax ticks all the boxes, arguably making it more a “go-anywhere” camera.

Battery, Storage, and Connectivity

Battery life details are sparse for Casio (NP-90 battery) but generally modest for its class. Pentax quotes about 260 shots per charge with a proprietary D-LI92 battery, reasonable for day trips.

Both rely on SD/SDHC storage cards with internal memory - nothing unusual here.

Interestingly, both cameras support Eye-Fi wireless card connectivity for direct image transfer, a neat feature before in-built Wi-Fi became standard. However, neither offers Bluetooth, NFC, or GPS, limiting modern connectivity options.

Real-World Use Across Photography Genres

Let's pivot to how these cameras fare in specific photography disciplines - an area where practical experience and technical factors converge.

Portrait Photography

Neither camera supports raw capture, which limits extensive post-processing of skin tones, but both CCD sensors provide pleasing color reproduction out-of-the-box.

• Casio lacks face detection and eye autofocus, so focusing can be a hit-or-miss in dynamic portraits.
• Pentax’s face detection AF improves keeper rate in snapshots, despite slow AF overall.

The Casio’s wider zoom range allows quick framing adjustments for headshots to environmental portraits, but its aperture tops out at F3.2 wide, which results in less subject-background separation compared to interchangeable lenses.

The Pentax’s slightly narrower lens range and F3.5 aperture are a drawback for bokeh but macro focusing can creatively extend portrait ideas (close-in detail shots).

Landscape Photography

Both cameras capture landscapes adequately with rich details under good lighting.

• Casio’s larger screen assists composition; higher native resolution aids cropping.
• Pentax’s outdoor-optimized LCD screen excels in sunny environments, plus it has a timelapse mode for dynamic landscape sequences.

Neither delivers extensive dynamic range, a limitation common to compact CCD sensors. Additionally, the lack of manual exposure controls restricts long exposure creativity often needed for landscapes (e.g., ND filter simulations or bulb mode).

Environmental sealing again favors Pentax for rugged landscapes.

Wildlife and Sports Photography

These genres demand fast autofocus and rapid shooting.

• Pentax WG-10 supports AF tracking and a continuous shooting mode at 0.7fps, slow but serviceable for casual wildlife photography.
• Casio cannot track AF and lacks continuous AF or burst shooting, making it largely unsuitable for moving subjects.

Neither camera is ideal for demanding sports photography requiring high frame rates and precision AF; professionals would seek dedicated DSLRs or mirrorless systems.

Street Photography

Compactness, discretion, and quick operation are key.

• Casio’s smaller, lighter body and 24mm wide angle give it an edge for candid street work.
• Pentax’s tougher build may be advantageous in accidental bumps but might draw attention due to its rugged appearance.

Low-light autofocus is a struggle for both, but Casio’s lower base ISO helps in ambient light scenes.

Macro Photography

Pentax’s 1 cm macro focus capability clearly outshines Casio (no data on macro capability).

Close-up shooters interested in flowers or small insects will find the WG-10 more versatile here.

Night and Astro Photography

Without manual exposure control or raw file output, both cameras are constrained.

Though Casio’s ISO 64 base may capture more clean exposures, lack of bulb mode and noise management makes them options of last resort for astrophotography.

Video and Travel

Pentax’s 720p/60fps video with H.264 codec is an advantage for casual videographers and travel vloggers, complemented by rugged body weatherproofing.

Casio’s limited 30fps 720p and Motion JPEG video is less flexible.

Battery life and compactness favors Casio for lightweight travel gear, but for adventurous trips where weatherproofing and durability matter, Pentax wins hands down.

Professional Usage and Workflow Integration

Neither camera supports raw capture, tethering, or advanced workflow features - limiting their appeal for commercial or professional work where flexibility and image quality matter.

Price and Value Assessment

The Casio typically comes in around $300, Pentax prices tend to fluctuate but the WG-10's rugged features often push it slightly higher, despite being an older model.

When considering price-performance, the Casio offers solid value for casual shooting and travel with versatility and resolution. Pentax offers niche value for durability, macro, and outdoor use.
