Although the sensor area is a standard compact size, the CMOS architecture enhances dynamic range capture and low-light sensitivity. It supports ISO 100-6400 (native) with optical image stabilization aiding handheld low-light shooting.

• Samsung HZ25W: Employs a CCD sensor of the same physical size but with a lower resolution of 12 megapixels (4000x3000). CCD sensors historically excel in color rendition but lag behind CMOS in noise control and high ISO capabilities. The ISO range is 64-3200 native, partially expandable to 6400, but noise degrades rapidly above ISO 800 in practical scenarios.

The technical consequence is that Panasonic’s CMOS sensor yields better noise control, improved dynamic range, and more versatile ISO flexibility supporting broader shooting environments.

Takeaway: The Panasonic ZS45’s CMOS sensor represents a notable image quality upgrade over the Samsung HZ25W’s CCD unit, particularly in low light and higher ISO domains, which is critical for fast-action sports, wildlife, and indoor portrait applications.
