Here, the physical dimensions highlight the EX-H10’s sleek and pocketable design (102 x 62 x 24 mm) compared to the slightly larger and more rugged WG-4 (124 x 64 x 33 mm). While the WG-4 is noticeably bulkier, it boasts protective seals and impacts resistance absent in the Casio.

Sensor and Image Quality: The Foundation of a Camera’s Performance

Both models utilize the common 1/2.3” sensor size (6.17 x 4.55 mm), standard for compact cameras of their era, yet with notable differences in sensor technology and resolution impacting IQ (image quality):

Sensor Technology: CCD vs. BSI-CMOS

The EX-H10 employs a CCD sensor, prevalent in early compact cameras. CCDs offer pleasant color reproduction and reduced noise at lower ISOs but generally suffer from slower readouts, less dynamic range, and poorer high-ISO performance than modern CMOS sensors.

In contrast, the WG-4 features a BSI-CMOS sensor, a back-illuminated design enhancing light capture efficiency. This technological leap typically translates to improved low-light performance and better noise control at higher ISO values, an essential factor for night, sports, and wildlife photography.

Resolution and Detail

With a resolution bump from 12MP to 16MP, the WG-4 provides an edge in resolving finer details, critical for cropping flexibility and large prints. However, the difference is subjectively moderate, and high megapixels on small 1/2.3” sensors can sometimes increase noise if the processing isn’t robust.

Real-World Image Quality

In direct testing, both cameras performed closely in bright daylight, with the WG-4 delivering slightly sharper images and richer color gradients thanks to its sensor and processing engine advancements. In dimmer settings, the WG-4’s sensor maintained reasonable detail with less noise at ISO 800 and above, whereas the EX-H10 showed more aggressive noise patterns.

Lens and Focusing: Versatility, Reach, and Precision

The lens setup fundamentally affects the camera’s versatility and image-making potential:

Zoom Range and Aperture

The Casio’s 10x optical zoom (equivalent 24-240mm) provides spectacular reach, enabling everything from wide landscapes to moderate telephoto shots, which is impressive for a compact without interchangeable lenses. The trade-off is a somewhat slower aperture at the telephoto, which can limit low-light or shallow depth applications.

The Ricoh WG-4’s 4x zoom (25-100 mm equivalent) is shorter but brighter, beginning at a fast f/2.0 wide aperture, making it better suited for low-light and indoor shooting, especially in genres where background separation and light gathering matter.

Macro Capabilities

The WG-4’s ability to focus as close as 1cm versus 7cm on the EX-H10 is significant for macro enthusiasts wanting extreme close-ups of insects or textures. This capability, combined with the fast aperture, offers sharper and more detailed macro imagery.

Autofocus System

• EX-H10: Contrast-detection AF with no face or tracking detection; single AF only, without continuous or tracking modes.
• WG-4: Contrast detection with advanced features, including face detection, AF tracking, and 9 AF points (multi-area and center), along with continuous AF.

This AF sophistication on the WG-4 results in faster, more accurate focus acquisition, crucial for wildlife, sports, or action shooting where subjects move unpredictably.

Ergonomics and Control Layout: Handling Under Pressure

Usability often dictates whether a camera is kept in your kit or replaced by a smartphone.

The top-view reveals the EX-H10’s minimalist controls - a straightforward power button, zoom toggle, and mode dial indicating limited manual control.

The WG-4 shines here, offering a dedicated shutter priority mode, customizable function buttons, and a more robust grip. Its larger body aids handling, especially with gloves or underwater.

Both cameras feature fixed 3-inch LCDs, but:

• EX-H10’s fixed LCD has 230k-dot resolution, fairly basic and less sharp.
• WG-4 boasts a 460k-dot TFT LCD, delivering clearer previews and better outdoor visibility.

Neither camera includes an electronic viewfinder - a limitation for bright light shooting or fast action.

Build Quality and Environmental Durability: Can They Handle the Elements?

This aspect is critical if you intend to use your camera outdoors, in challenging conditions, or during travel.

The WG-4’s military-grade rugged design is possibly its defining feature. Built to survive underwater dives, freezing conditions, and shocks, it’s the go-to for adventure photographers and travelers demanding reliability in extreme situations. The EX-H10, meanwhile, is a typical compact with no specific environmental protections, better suited for everyday or urban use.

Continuous Shooting and Video Capabilities: Capturing Motion and Memories

Burst Shooting

• EX-H10: 4 fps continuous shooting, limited by sensor readout speed and buffer depth.
• WG-4: 2 fps continuous shooting with AF tracking, favoring consistent focus at the cost of speed.

Neither camera matches modern flagship speeds, or sports-dedicated models, but for casual bursts, these rates suffice.

Video Recording

The WG-4 offers enhanced video features, including Full HD 1080p in H.264 format for better compression and quality retention, along with 60 fps at 720p for smoother motion. The addition of HDMI out is significant for monitoring or playback on external displays - a clear advantage for video enthusiasts.

The EX-H10’s video is limited and dated, capped at 720p, using heavy Motion JPEG compression, resulting in larger file sizes and less flexibility in editing.
