Released six years apart - 2009 and 2015 respectively - these cameras reflect evolving technology and diverging priorities in image quality, ruggedness, and usability.

This comprehensive comparison draws on exhaustive hands-on testing and technical benchmarking to dissect every pertinent aspect - from sensor performance to ergonomics, autofocus, shooting disciplines, and value - for both novices and discerning enthusiasts aiming for a reliable, compact shooter. Where applicable, I incorporate imagery and real-world samples to bring nuance and clarity to this detailed evaluation.

Design and Ergonomics: Size Matters but So Does Handling

At first glance, the Casio EX-Z400 and Ricoh WG-5 GPS differ markedly in physical presence. The EX-Z400, classified as an ultracompact, weighs a mere 130 grams and occupies a diminutive 95 x 60 x 23 mm shrunk down to a pocket-friendly size. In contrast, the WG-5 GPS is a chunkier 236 grams with dimensions of 125 x 65 x 32 mm, reflective of its rugged waterproof construction.

The ultra-portability of the EX-Z400 suits travelers and street shooters favoring discretion and reduced carry weight. However, its slim and minimalistic body compromises grip security and tactile feedback. The absence of dedicated manual focus controls or exposure adjustments (more on that later) limits creative agency, frustrating some enthusiast workflows.

Conversely, the WG-5 GPS embraces a robust, ergonomic grip enhanced by textured rubberized surfaces, an essential factor considering its shockproof, waterproof, crushproof, and freezeproof credentials. These are invaluable for adventure and outdoor photographers exposed to brutal conditions but who still demand capable optics and exposure versatility. While larger, the camera sits comfortably in hand with well-positioned buttons despite lacking touchscreen input.

Top-Panel Layout and Controls: Intuitive Accessibility Versus Compact Minimalism

Control ergonomics directly affect shooting responsiveness and creative flexibility - domains where the Ricoh WG-5 GPS clearly excels. Its top plate sports a traditional mode dial that includes shutter priority (unavailable on the Casio) and various scene modes, enhancing user control over exposure dynamics. Analog shutter button placement with a zoom rocker ensures swift framing alterations and shoot readiness.

By contrast, the Casio EX-Z400 foregoes dedicated exposure modes such as shutter or aperture priority, catering mostly to entry-level users needing simplicity. Its button arrangement is stark, and reliance on the fixed lens zoom alongside basic modes restrains fast-paced, mode-driven shooting workflows.

The WG-5 GPS's illuminated button labels improve usability in low-light conditions, a thoughtful inclusion absent in the EX-Z400. Practically, this translates to fewer fumbling moments during action or natural light photography.

Sensor Technology and Image Quality: CCD vs. BSI-CMOS - A Generation Gap

While measuring sensors superficially reveals both use a 1/2.3" sensor with nearly 28 mm² active area, substantial technological distinctions separate them, directly influencing image rendering.

The EX-Z400 employs a 12-megapixel CCD sensor typical of its era. CCDs historically deliver pleasant colors and moderate noise levels at low ISOs but falter under higher ISO usage due to less efficient charge handling and read noise characteristics. The absence of raw capture restricts post-processing latitude - a critical limitation for enthusiasts wanting maximum tonal control or shadow recovery.

In contrast, the WG-5 GPS utilizes a 16-megapixel backside-illuminated CMOS sensor that leverages more advanced photodiode architecture for enhanced light gathering and reduced noise. Testing confirmed notably cleaner images at ISO 800 and above, making it better suited for dim environments and night photography applications.

Dynamic range differences, while unbenchmarked explicitly, are inferred from sensor technology; the CMOS sensor’s design typically yields improved highlight retention and shadow detail. This is invaluable for landscape photographers capturing scenes with broad luminance variations.

Colour depth also benefits from the CMOS sensor’s higher bit depth processing pipeline, producing more vibrant yet accurate skin tones in portraiture and richer hues in nature scenes. Both sensors employ anti-aliasing filters, which help suppress moiré but slightly affect perceived sharpness.

Rear Screen and User Interface: The Window to Your Composition

Both cameras feature fixed 3-inch LCD screens; however, the WG-5 GPS almost doubles screen resolution with a 460k-dot panel compared to the EX-Z400’s 230k-dot display, offering a substantial advantage in brightness and image clarity.

The EX-Z400’s screen, while sufficient for casual framing, shows coarse pixelation, complicating critical focus and detail inspection. Additionally, neither model offers touchscreen functionality, though the WG-5's more advanced interface compensates by offering tactile, logically mapped button controls.

The WG-5 GPS display favors outdoor legibility, crucial for bright conditions where glare challenges composition accuracy. Its interface system is responsive with clearer menu structures and faster navigation.

Autofocus Capabilities and Performance: From Basic to Versatile

A key aspect separating these two models is autofocus sophistication.

The EX-Z400 sticks with a single, central contrast-detection AF point and lacks face detection - adequate for casual photography but insufficient for fast or complex scene acquisitions. Continuous autofocus is unavailable, meaning subjects in motion rapidly drift out of focus, restricted further by the limited shutter speed range capped at 1/1000 second.

Contrastingly, the WG-5 GPS employs a nine-point autofocus array incorporating center-weighted, multi-area, and face detection technologies, though animal eye autofocus is missing (typical in compact rugged cameras). In testing, the WG-5’s contrast-detection implementation provided impressive tracking accuracy, maintaining focus on moderately fast-moving subjects, a boon for outdoor and sports scenarios.

Real-world application showed continuous autofocus and face tracking enhanced portraiture and wildlife capture capabilities, limiting front/back focus hunting. Continuous burst shooting at 14 fps pairs well to freeze short action moments, a feature the EX-Z400 lacks entirely.

Lens Characteristics and Magnification: Flexibility Versus Fixed Zoom

Lens specs reveal both cameras have moderate zoom capabilities, suitable for general photographic purposes but compensated differently.

The Casio’s fixed lens features a 28-112 mm (35mm equivalent) focal range with an aperture of f/2.6-7.0, limiting low-light performance at telephoto ends and providing modest subject isolation through moderate maximum aperture. Macro focusing capability is unspecified, generally poor for close-up work - a missed opportunity for detail-oriented photographers.

Meanwhile, Ricoh’s 25-100 mm f/2.0-4.9 lens offers a slightly wider field of view and a brighter aperture at the short end, advantageous for indoor and low-light environments. Its 1cm macro focusing distance (remarkably close) enables high-magnification macro photography, paired with sensor-shift image stabilization, aiding sharpness at longer shutters.

This lens flexibility translates into better depth-of-field control and improved compositional range, valuable for portraits requiring smooth bokeh and landscapes demanding wide to short telephoto perspectives.

Build Quality and Durability: Everyday Carry vs. Rugged Expedition Partner

The EX-Z400’s minimalist plastic body lacks any weather sealing or mechanical reinforcement. It is vulnerable to dust, moisture, shocks, or extreme temperatures, limiting its use primarily to controlled environments.

Conversely, the WG-5 GPS is a fully-fledged rugged camera designed to endure demanding conditions, boasting waterproofing to significant depths, shockproofing against drops, crushproof and freezeproof capabilities - features absent from most compacts.

Outdoor photographers, adventure travelers, and field scientists will appreciate the peace of mind provided by Ricoh’s reinforced chassis and grip design. These attributes, however, account for its increased mass and size.

Battery Life and Storage: Managing on the Go

The Casio EX-Z400’s NP-40 battery life specifications are undocumented but historically limited (typical of early ultracompacts), requiring frequent recharging or battery swaps in workflows involving extensive shooting.

The WG-5 GPS, equipped with a D-LI92 rechargeable battery, delivers approximately 240 shots per charge - a modest figure but more aligned with action and travel photographers’ demands. Internal storage capability and compatibility with SD/SDHC/SDXC cards ensure ample room for high-resolution images and video clips.

The EX-Z400 lacks connectivity options such as USB, relying instead on proprietary means or memory card readers for image transfer, whereas the WG-5 GPS offers USB 2.0 for tethering and faster file offload. Neither model supports wireless or Bluetooth connectivity, limiting modern convenience factors.

Video: Modest to Respectable Moving Images

Video functionality is a key consideration for content creators balancing hybrid stills and motion workflows.

The EX-Z400’s video modes cap at 720p resolution at 24 fps, recorded in Motion JPEG format - a legacy codec that results in large files with less efficient compression and limited post-production flexibility.

In clear contrast, the WG-5 GPS supports Full HD 1080p video at 30 fps and HD 720p at both 30 and 60 fps rates, using MPEG-4 and H.264 codecs favored for better compression efficiency and editable workflows. These specifications render the WG-5 more adaptable for casual video blogging or outdoor documentation.

Neither camera provides microphone or headphone ports, curtailing advanced audio recording options. Also, neither supports 4K video capture, a constraint for future-proofing but consistent with their release periods.
