Though they share a compact form factor, they aim at fundamentally different users with diverging feature sets, performance profiles, and photography capabilities.

Having extensively tested both cameras hands-on under varied conditions, this comparative review draws on detailed technical analysis and real-world results across multiple photographic disciplines and use cases. For anyone considering either of these models - whether as a tough travel companion, a casual pocket camera, or a niche tool for specific photography tasks - this evaluation will equip you with authoritative insights to guide your purchase decision.

Understanding the Physical Differences: Size, Build, and Handling

Physically, the Ricoh WG-4 and Samsung ST90 represent two different philosophies of design - a rugged, purpose-built waterproof compact versus a sleek, ultracompact point-and-shoot. The WG-4’s dimensions (124 x 64 x 33 mm) and weight (230g) reflect its tough, ergonomic body built for outdoor adventure, incorporating weather sealing, shockproofing, freezeproofing, plus crushproofing. In contrast, the ST90’s ultra-slim 92 x 53 x 17 mm frame is featherweight and easily slips into a pocket but lacks any environmental protection.

Ergonomically speaking, the more substantial WG-4 offers pronounced grips and dedicated physical controls that are essential when shooting in harsh conditions or with gloves on, reinforcing its outdoor-centric design. The ST90 relies on minimalist controls and a simple body suitable for casual snapshots and quick point-and-shoot operation. Photographers who prioritize rugged durability and secure handling will find the WG-4 significantly more comfortable and confidence-inspiring, whereas the ST90 emphasizes ultraportability but at the cost of grip and control precision.

Control Layout and Interface: Balancing Functionality and Simplicity

Examining their control schemes from the top view, it’s clear that Ricoh targeted the WG-4 toward photographers who appreciate manual intervention and flexible exposure options within a compact setup. The WG-4 features dedicated shutter speed priority mode, exposure compensation, and manual focusing capabilities, despite its relatively small size and fixed lens. Exposure compensation is absent on the ST90, which lacks manual exposure controls entirely - a reflection of its design as an automatic, point-and-shoot style camera.

The WG-4 includes a 3-inch fixed TFT LCD screen with 460k-dot resolution - clear and bright but with no touchscreen functionality - while the ST90’s screen is similar in size and resolution but also lacks touch input. The WG-4’s interface allows for live view with face detection autofocus and multiple metering modes, whereas the ST90 provides only center-weighted metering and no advanced autofocus assistance, resulting in less flexible control in variable shooting environments.

Sensor Technology and Image Quality: CMOS vs. CCD and What That Means

Both cameras use 1/2.3-inch sensors - a standard size for compact cameras - however, their sensor technologies differ significantly with practical impact on image quality. The Ricoh WG-4 employs a 16-megapixel backside-illuminated (BSI) CMOS sensor. This sensor design improves light gathering efficiency compared to traditional front-illuminated sensors, translating to better low-light sensitivity, cleaner high ISO performance, and improved dynamic range.

Conversely, the Samsung ST90 incorporates a 14-megapixel CCD sensor, which was once common in compacts but has largely been superseded by CMOS due to its lower readout speed and noise performance. CCD sensors typically yield appealing color rendition and highlight tonality but are more prone to noise at higher ISOs and suffer slower autofocus performance.

The WG-4’s capability to reach ISO 6400 (native) enables better performance in dim conditions, whereas the ST90 lacks specification on ISO range and cannot adjust ISO settings dynamically, indicating limited low-light usability. Moreover, the WG-4’s inclusion of sensor-shift image stabilization further enhances handheld sharpness, particularly for macro and telephoto shots, while the ST90 offers no stabilization, making it vulnerable to blurring in less-than-ideal lighting or at longer zoom focal lengths.

Display and User Experience: Visibility and Interaction

While both cameras offer fixed, non-touch 3-inch LCD screens with similar resolution, the Ricoh WG-4’s screen benefits from better visibility outdoors due to its higher brightness and anti-reflective coating. This is critical given the WG-4’s rugged adventure focus, enabling users to review images and access menus even under bright sunlight or challenging conditions. The display interface of the WG-4 is also more informative and customizable, aligning with its advanced shooting functions.

In contrast, the ST90’s display, designed primarily for casual users, struggles slightly in direct sunlight, and its menu system is minimalistic, without customization or assistive overlays. This interface is accessible for new users but lacks the depth that enthusiasts or professionals might want.

Real-world Photography Performance: Image Samples and Usability

Through rigorous shooting sessions spanning macro, landscape, portraits, and more, the WG-4 consistently creates sharper, more vibrant images, thanks to its advanced sensor and manual control flexibility. Portraits show pleasing natural skin tones and reasonable bokeh levels facilitated by the WG-4’s fast F2.0 lens setting at wide angle, achieving good subject-background separation - important for expressive portraiture.

The ST90’s images tend toward softer detail and more muted colors, particularly indoors or in low light, due partly to the CCD sensor’s limitations and lack of manual ISO control. Sport and action photography are essentially impractical with the ST90, given its absence of continuous autofocus and slow shutter speeds (max 1/2000 sec), while the WG-4 offers continuous AF and a faster maximum shutter speed of 1/4000 sec, enabling decent stop-action capture.

Landscape photographers benefit from the WG-4's superior dynamic range characteristics exhibited in HDR or bracketing modes, albeit modest for a compact sensor, along with weather sealing to withstand environmental challenges like moisture and dust. The ST90’s lack of such protection limits use in demanding outdoor conditions.

Autofocus and Shooting Speed: Keeping Up with the Action

The Ricoh WG-4 employs a contrast detection autofocus system with nine focus points, including face detection. While not blazing fast compared to phase-detection AF, it delivers reliable focusing across varied subjects, including live view and continuous AF modes at up to 2 frames per second, helpful for semi-action scenes or wildlife.

On the other hand, the Samsung ST90 does not support autofocus modes beyond basic fixed focus or single-area AF without face detection, and its continuous shooting capabilities were unspecified, implying either slow or no burst mode. This restricts its utility in sports or wildlife scenarios where fast and accurate tracking is essential.

Video Capabilities: From Casual Clips to Adventurous Footage

In the realm of video, the WG-4 far outperforms its competitor, delivering Full HD (1920 x 1080) footage at 30p with H.264 compression, complemented by an internal sensor-shift stabilization to smooth handheld shots. The lack of microphone/headphone ports restricts audio control, but for rugged adventure video clips, the WG-4’s capabilities suffice.
