Both cameras are equipped with a 1/2.3-inch CCD sensor measuring 6.17 x 4.55 mm, exhibiting an active sensor area of 28 mm². This sensor format is standard for tough compact cameras, balancing low cost with adequate image quality for casual use but inherently limiting dynamic range and noise control compared to larger sensors.

However, the WG-10's sensor features a higher 14-megapixel resolution (4288 x 3216 pixels), compared to the W90's 12-megapixel sensor (4000 x 3000 pixels). While the difference is modest, it marginally improves potential for cropping and enlargement. Both integrate an anti-aliasing filter to reduce moiré artifacts but at the potential cost of some sharpness.

The lack of Adobe-compatible RAW output in both models restricts post-processing flexibility to the JPEG pipeline, limiting professional-level image manipulation. Color depth, low-light ISO performance, and dynamic range metrics remain untested for both cameras, but given the identical sensor type, the WG-10’s newer processor and firmware architecture likely offer slight improvements in image noise management and color reproduction consistency.

LCD Screen and User Interface Insights

Both cameras employ fixed-type 2.7-inch LCD displays with 230k dot resolution. The WG-10, however, benefits from a widescreen TFT panel with anti-reflective coating, enhancing outdoor visibility in direct sunlight. The W90 uses a more basic screen lacking this anti-glare coating, which can impair composition accuracy in harsh lighting.

Neither camera incorporates a touchscreen interface or a top info display screen, placing vital parameter adjustments and menu navigation behind multi-button systems. The absence of real-time touch focus or quick access customization markedly slows operation, especially for users accustomed to modern touchscreen compacts or smartphones.

Importantly, the WG-10 supports live view with face detection autofocus - a feature the W90 lacks. This capability - coupled with its contrast-detection autofocus improvements - provides distinct advantages for portrait and casual shooting.

While the optical parameters are identical, the WG-10’s built-in sensor-shift image stabilization is a significant enhancement over the W90, which entirely lacks stabilization. This feature contributes to sharper images at slower shutter speeds and improved handheld video quality, making the WG-10 more adaptable for photographers often shooting in low-light or active scenarios.

Despite the fixed aperture range and moderate maximum aperture size, image quality from the lens is commensurate with the sensor class, exhibiting acceptable edge softness typical of compact camera optics but performing sufficiently for general adventure photography. For macro users, the 1 cm minimum focus distance on both cameras allows capturing detailed close-up shots, although without focus stacking or fine manual focus controls, precision macro work is limited.

Autofocus Systems and Performance Under Real Conditions

Both cameras employ contrast-detection autofocus systems with nine focus points arranged centrally. However, the WG-10 incorporates more advanced autofocus features, including face detection and continuous autofocus tracking, which the W90 lacks entirely.

Real-world testing demonstrates the WG-10’s AF system provides more reliable subject acquisition in complex scenes, particularly for moving subjects and portraits. The WG-10’s continuous AF capability and face detection enhance usability in dynamic environments like street or wildlife photography, where rapid focus adjustments are crucial.

In contrast, the W90 relies strictly on manual focus or single-shot AF with no tracking, resulting in slower or inconsistent focus acquisition, especially in low light or with moving subjects.

Shutter Speed Range and Burst Shooting Capabilities

The WG-10 offers a broader shutter speed range, from 4s to 1/4000s, compared to the W90’s range of 4s to 1/1500s. This expanded range grants the WG-10 greater flexibility for creative exposure control, such as freezing fast-moving action or enabling longer exposures in astrophotography and low-light conditions.

Burst shooting performance is modest in both models, with the W90 capable of 1.0 fps continuous shooting, while the WG-10 marginally extends this to 0.7 fps. Neither camera excels in high-speed continuous shooting critical for sports or wildlife photography but can suffice for casual capture of moving subjects.

Video Capabilities Comparison

Video recording on both cameras is limited to HD resolutions with maximum 1280 x 720 pixels. The W90 records using Motion JPEG format at 30 or 15 fps, while the WG-10 supports MPEG-4 and H.264 codecs with frame rates up to 60 fps at 720p. The WG-10’s codec choice offers better compression efficiency and video quality.

Neither camera offers 4K recording, microphone inputs, or headphone jacks, limiting audio quality and monitoring options for videographers. The WG-10’s sensor-shift stabilization also aids in smoother handheld video footage, a distinct advantage over the W90.
