A high-resolution 1/1.8′′ 4-megapixel CCD and a small high-performance 3x optical zoom lens (equivalent to 35-105 mm in 35 mm format) distinguish the PowerShot S45 from its predecessor, the PowerShot S40, which was introduced in October 2001.

The PowerShot S45 contains new technologies that improve image quality, functionality, and operability, among other things. Included in this is an increase from 3-point to 9-point Autofocus Interval Autofocus (AiAF), which ensures precise autofocus performance with unfettered framing, regardless of the position of the subject inside the viewfinder.

Furthermore, when the camera is used in the vertical position, Canon’s SI (Super Intelligent) sensor automatically identifies the orientation of the camera, providing optimal Auto-Focus, Auto-Exposure, and Auto-White Balance performance. In addition, the SI sensor automatically aligns the picture for previewing as it is captured.

The PowerShot S45 has a stylish body that has been designed for improved handling, portability, and ease of use. It also incorporates many of the high-end features of the PowerShot G3—including a plethora of manual settings—to meet the needs of even the most advanced users while maintaining its affordability.
