Sensor and Image Quality: A Comparative Look at Imaging Capabilities

Central to photographic output is the sensor technology and associated image processing pipeline.

Both cameras utilize a 1/2.3" CCD sensor, an older technology marked by reasonable sharpness but limitations in noise control and dynamic range, especially when pushed beyond native ISOs.

Resolution and Detail

The WG-10’s 14MP sensor yields slightly higher pixel density, which can translate to finer resolution and better cropping latitude in practice. However, the difference is modest and might only be discernible under controlled conditions or large print output demands.

ISO and Noise Control

Where the WG-10 notably extends to ISO 6400, the SL620 caps at 1600. This difference suggests the WG-10 provides more flexibility for low-light conditions, although as both employ CCD sensors, noise levels above ISO 800 are significant and image degradation becomes noticeable.

Dynamic Range and Color Depth

Neither manufacturer provides detailed dynamic range or color depth metrics, but CCD sensors of this class typically offer limited DR compared to modern CMOS sensors. Real-world tests show both cameras retaining acceptable highlight detail in moderate lighting but struggling with deep shadow recovery.

Lens Characteristics

• WG-10: 28-140mm equivalent focal length (5× zoom) with aperture f/3.5-5.5
• SL620: 35-175mm equivalent focal length (5× zoom) with aperture f/2.8-5.7

The WG-10’s wider-end 28mm equivalent aids in landscapes and interiors, whereas the SL620's brighter f/2.8 aperture at widest focal length allows better performance in low light and improved subject isolation, critical in portrait and street photography.

Display and Live View Experience

Both models share a 2.7-inch fixed LCD of 230k-dot resolution without touchscreen capability. This resolution is adequate for framing but limits sharpness in reviewing small details critically, such as checking focus precision or subtle image noise.

Neither camera includes an electronic viewfinder, requiring reliance on the LCD in all lighting environments. This imposes certain usability limits outdoors, especially under bright sunlight, despite the WG-10's anti-reflective coating. The SL620 lacks any anti-reflective technology, making live view visibility problematic under direct ambient light.

Autofocus and Focusing Performance

AF capabilities critically affect performance in dynamic situations like wildlife or sports. Both cameras deploy contrast-detection autofocus systems with a limited number of focus points.

The WG-10 additionally offers tracking AF designed to maintain focus on moving subjects - a rare feature for a compact of its generation - and face detection. However, autofocus speed is generally slow by modern standards, with continuous shooting severely limited (0.7 fps on WG-10, no continuous burst info on SL620).

This limits usefulness for fast-moving sports or wildlife photography, where professional-level AF systems with phase detection and higher frame rates are essential.

Photography Genre Suitability and Real-World Performance
