• Users seeking extreme zoom range in a single package, tolerating less flexibility in exposure control, may find the HZ25W’s design better aligns with their needs despite its increased bulk.

Sensor Technology and Fundamental Image Quality

At the heart of any camera’s image quality potential lies its sensor. The Olympus E-P1 is equipped with a 12MP Four Thirds CMOS sensor sized at 17.3x13 mm (224.9 mm² sensor area), significantly larger than the Samsung HZ25W’s 1/2.3” CCD sensor measuring 6.08x4.56 mm (27.72 mm²). Sensor size directly influences noise performance, dynamic range, and depth of field control.

The E-P1’s sensor architecture benefits from higher native ISO capabilities (100–6400), with measured usable ISO up to 536 in low light according to DxOmark, and a substantial dynamic range of 10.4 EV. The sensor also employs an antialiasing filter, typical of the era, which slightly affects micro-detail rendering but reduces moiré artifacts.

By comparison, the Samsung’s smaller CCD sensor is constrained to a maximum native ISO of 3200 (extendable to 6400) but generally suffers from more noise and less dynamic range in practical shooting. It also operates with fewer exposure controls and a narrower acceptable sensitivity range due to physical limitations.

Image Quality Considerations:

• The larger Four Thirds sensor confers superior low-light performance, greater tonal gradations, and enhanced bokeh potential on the E-P1.
• The Samsung’s sensor excels in versatility courtesy of its zoom range but compromises image quality with higher noise levels and less detail resolution, especially when shooting beyond ISO 400.

Both cameras feature primarily contrast-detection autofocus systems - a prevailing standard for the era - but with differing degrees of sophistication and functionality.

The E-P1 features:

• 11 autofocus points with multi-area and contrast-detection AF.
• Face detection enabled.
• Single AF, continuous AF for video, and selective AF options.
• However, it lacks advanced tracking AF or animal eye AF support.

The HZ25W offers:

• Contrast-detection AF with center-weighted and multi-area modes.
• No face or eye detection.
• Single AF only; continuous AF is not supported.

Operational Impact:

• In portrait and street photography, the E-P1’s face detection can improve framing and focusing speed on human subjects.
• The Samsung’s AF system, while adequate for static subjects, tends to lag in dynamic scenarios and can struggle with precision in low light due to its sensor and lens limitations.
• Neither camera provides phase-detection or hybrid AF, so both will be slower than contemporary mirrorless or DSLRs with phase-detection pixels.
