Both lack electronic viewfinders, relying exclusively on rear LCDs - a common omission in budget and compact models but notable for photographers accustomed to eye-level composition.

Sensor Technology and Image Quality: Heart of Performance

At the core of any camera's photographic capability is its sensor technology, which dictates image detail, dynamic range, noise performance, and ultimately, creative latitude.

The standout difference here is sensor size: the Sony a5000 employs an APS-C sensor measuring 23.2 x 15.4 mm (357.28 mm²), considerably larger than the HX20V’s 1/2.3-inch sensor (6.17 x 4.55 mm, 28.07 mm²). This difference of over twelvefold in sensor area not only facilitates higher resolution (a5000’s 20 MP vs HX20V’s 18 MP) but underpins fundamentally superior image quality in the a5000.

The a5000’s sensor adheres to the widely acclaimed Sony Bionz X image processing pipeline, delivering impressive color depth (23.8 bits per DxO Mark) and dynamic range (~13 EV), allowing more flexibility in post-processing to recover shadows and highlights. In contrast, the HX20V’s sensor, while competent for casual snaps, struggles comparatively in low light, evident from its limited dynamic range and higher noise levels at ISO above 800.

This disparity reveals itself starkly when shooting challenging lighting scenarios - such as backlit portraits or contrast-heavy landscapes - where the a5000's APS-C sensor provides cleaner images with truer colors and finer tonality transitions.

Autofocus Systems: Precision & Speed Under Scrutiny

Autofocus accuracy and speed often make or break the photographic moment, especially in genres like wildlife and sports.

The Sony a5000 features a 25-point contrast-detection autofocus system, including face detection, continuous AF, and tracking capabilities. While lacking phase-detection autofocus points (which typically offer faster focus acquisition), the a5000’s AF system remains reliable for static subjects and moderate motion, offering continuous AF tracking that can fulfill casual sports or street photography needs.

Conversely, the HX20V uses a 9-point contrast-detect AF system, limited by the compact sensor size but achieving faster locking in bright daylight. Its implementation emphasizes quick acquisition over precision, suitable for high zoom flexibility but less adept at subject tracking in complex scenes.

Notably, neither camera supports animal eye AF or sophisticated subject recognition now common in higher-end models, potentially limiting wildlife photography performance.
