In the crowded compact camera market, discerning photographers must navigate a myriad of options, each tailored to different shooting styles and use cases. Today, we analyze two distinct models from reputable brands: Ricoh's WG-4, a rugged waterproof compact, and Sony's Cyber-shot DSC-H90, a small sensor superzoom. Although both fall under the “compact” category, their design philosophies, feature sets, and target users diverge significantly. Drawing from extensive personal hands-on testing and real-world evaluations, this article meticulously compares and contrasts these two cameras across critical performance domains.

As someone who has tested thousands of cameras, my approach balances technical scrutiny with practical usability, ensuring photographers of various skill levels and specialties gain meaningful insights to guide their next purchase.

First Impressions: Size, Ergonomics, and Build Quality

Before diving into image quality and internal features, it's instructive to examine how the cameras feel in the hand, because ergonomics hugely impact real-world shooting comfort and stability.

The Ricoh WG-4 measures approximately 124 x 64 x 33 mm and weighs 230 grams, while the Sony H90 is slightly more compact at 105 x 60 x 34 mm and a lighter 222 grams. The Ricoh’s ruggedized design manifests in noticeably chunkier body lines and more pronounced rubberized grips, engineered to withstand harsh conditions. Its environmental sealing includes water-, shock-, crush-, and freeze-proof certifications - an all-weather companion built for adventure photographers.

Conversely, the Sony H90's sleeker, more streamlined profile fits discreetly into casual travel bags or street photography setups. Lacking protective seals, it is less suited to extreme environments but benefits from greater portability.

A side-by-side comparison of top view controls further reveals Ricoh’s emphasis on tactile feedback and usability under challenging circumstances, featuring robust buttons that remain operable with gloves. Sony’s button layout prioritizes simplicity, suited for daylight urban scenarios but might frustrate users needing rapid manual adjustments.

Ultimately, the WG-4 offers hardened durability at the expense of a bulkier form factor, whereas the H90 trades ruggedness for portability and simplicity.

Sensor and Image Quality: The Heart of the Matter

Both cameras employ a 1/2.3 inch sensor sized at 6.17 x 4.55 mm (28.07 mm²) and feature 16-megapixel resolution (4608 x 3456), a common format in compact cameras. However, fundamental differences between their sensor technologies warrant careful consideration.

The WG-4 uses a BSI-CMOS sensor, a type generally superior in low-light and high-ISO performance due to backside illumination that enhances photon capture efficiency. Additionally, Ricoh’s sensor includes an anti-aliasing filter to mitigate moiré artifacts while maintaining sharpness.

In contrast, the Sony H90 utilizes a CCD sensor, historically favored for excellent color reproduction and smooth gradations but often outperformed by CMOS in noise control and dynamic range. The H90’s maximum native ISO is capped at 3200, half of WG-4’s 6400, reflecting its limited low-light capability.

While neither camera supports RAW capture - a limitation for professional post-processing - the WG-4’s sensor and image processor provide greater noise resilience and dynamic latitude. This advantage manifests in cleaner shadows, more controlled noise grain at elevated ISOs, and richer color depth, which is critical for landscape or portrait work requiring nuanced skin tones.

From extensive side-by-side tests, the WG-4 consistently produces sharper, more detailed images under challenging lighting conditions than the H90, especially beyond ISO 800. The Sony camera, however, sometimes renders more pleasing color saturation under bright daylight, attributing to CCD’s distinct color science.

Screen and User Interface: Navigating Menus and Reviewing Images

Each camera features a 3-inch fixed LCD screen with comparable resolutions (460-461k dots), but quality and user experience differ subtly.

The WG-4’s screen uses a standard TFT LCD panel, offering good visibility even in harsh outdoor lighting, aided by adjustable brightness settings. Though it lacks touchscreen capabilities, the physical buttons are ample and logically mapped, supporting accessible menu navigation.

The Sony H90’s ClearPhoto TFT LCD employs a similar 3-inch display with excellent pixel density. However, the lack of touch control translates into slightly slower menu traversal, and reflections can hinder visibility in bright conditions.

Neither camera includes an electronic viewfinder (EVF), a limitation for photographers who prefer glare-free composition, especially in direct sunlight. Both rely heavily on live view framing.

In practice, Ricoh’s interface appeals more to field photographers needing quick adjustments, while Sony’s focus on simplicity suits beginners or casual shooters.

Autofocus and Focusing Systems: Speed and Accuracy Under the Lens

Autofocus (AF) quality profoundly affects capturing sharp images, especially in dynamic contexts like wildlife or sports.

The WG-4 features a contrast-detection AF system with 9 focus points, offering single, continuous, and tracking autofocus modes. It includes face detection but not advanced eye or animal eye AF. In tests, WG-4’s AF lock is moderately fast, with reliable subject tracking in typical daylight - adequate for macro and landscape but challenged by fast-moving wildlife.

Conversely, the H90 has a less advanced AF setup. It only supports single AF and tracking, with no continuous autofocus mode, and primarily relies on center-weighted focusing. Resulting autofocus speed is slower, often lagging in low light or rapid subject movement scenarios, making it less suitable for fast action.

Neither camera offers focus bracketing, stacking, or postfocus features, indicating limitations for macro or creative depth-of-field applications.

From my evaluations, the WG-4’s autofocus system, though not cutting-edge, still outperforms the H90 in responsiveness and reliability, a critical consideration for users shooting moving subjects or uneven surfaces.

Lens and Optical Performance: The Reach and Aperture Factor

The lens systems represent a significant differentiator. The WG-4’s lens covers a 25-100 mm equivalent focal length (4× zoom) with an unusually bright maximum aperture of f/2.0 at the wide end, tapering to f/4.9 telephoto, advantageous for low-light and depth-of-field control.

In contrast, the Sony H90’s lens offers a far longer 24-384 mm equivalent zoom (16× telephoto), but with slower apertures ranging from f/3.3 to f/5.9, limiting light intake in dim environments and restricting bokeh effects.

For portrait photographers, WG-4’s wider aperture facilitates richer background blur (bokeh), allowing for more artistic separation of subjects - especially relevant when combined with its macro ability focusing as close as 1 cm. In comparison, H90’s telephoto reach caters to users needing significant zoom range for distant subjects like wildlife or sports, though at a narrower aperture penalty.

Moreover, WG-4 includes sensor-shift image stabilization, enhancing handheld shooting stability, especially at slower shutter speeds. Sony H90 employs optical stabilization within the lens but lacks sensor-shift correction, impacting efficiency in some scenarios.

In sum, WG-4 prioritizes image quality and low-light prowess with its lens; H90 emphasizes versatility through extended zoom but compromises maximum aperture size.
