• The Sony A58 is a more substantial entry-level DSLR alternative utilizing Sony’s translucent mirror technology (Single-Lens Translucent, or SLT). It has a 20MP APS-C (23.2x15.4 mm) CMOS sensor, interchangeable lenses, and extensive manual controls.

Handling and Ergonomics Snapshot

Comparing their physical dimensions and weight reveals a stark contrast: the compact Samsung weighs just 249 grams with slim proportions (105 × 61 × 37 mm), while the Sony A58 nearly doubles that at 492 grams and sports a considerably larger 129 × 95 × 78 mm body. This difference influences handling comfort, portability, and grip security significantly.

While the HZ15W is perfect for discreet street or travel photography due to its pocketable form factor, it lacks extensive physical controls. The Sony’s bulkier form factor accommodates a robust grip and more direct access to buttons and dials - crucial for manual adjustments during demanding shoots.

Sensor Technology and Image Quality: Battle of Generations

The heart of any camera’s image quality lies in its sensor architecture and processing capabilities. These two models are from different generations and classes, leading to noteworthy differences.

Sensor Specifications and Impact

The A58’s APS-C sensor is roughly 12.5 times larger in surface area than the HZ15W’s sensor, allowing vastly superior light gathering capability, lower noise at high ISO, improved dynamic range, and more detailed captures.

While the Samsung’s CCD sensor technology was respectable for compact cameras in 2009, it suffers from limited ISO sensitivity and reduced dynamic range, impacting low-light and contrasty scenes adversely.

In contrast, the Sony’s 20MP CMOS sensor, equipped with a BIONZ image processor, supports robust high-ISO performance, exceptional color fidelity, and preserves fine detail even in challenging lighting - qualities critical for professional and enthusiast use.

Autofocus and Shooting Performance: Speed and Precision Comparison

Autofocus (AF) is vital for capturing decisive moments, especially in wildlife, sports, and street photography.

Autofocus System Architecture

The Samsung HZ15W uses a basic contrast-detection AF system with center-weighted area and face detection but lacks continuous, tracking, or phase-detection capabilities.

The Sony A58’s standout feature is its 15-point phase-detection AF system on the translucent mirror sensor, which provides fast, accurate, and continuous autofocus with subject tracking - a remarkable advantage for dynamic scenes.

The Sony’s continuous autofocus coupled with its 8 fps continuous shooting rate supports burst photography, making it suitable for wildlife, sports, and fast action - modes unattainable on the Samsung due to hardware limitations.
