- Q18
- What is the difference between optical zoom and other different types of zoom?
- A18
- The camera is equipped with various types of zoom: optical zoom, HD Zoom, Single SR Zoom, Multi SR Zoom, and digital zoom.
• Optical Zoom :
Changes the lens focal distance.
• HD Zoom :
Allows greater zoom capabilities by cutting out a portion of the original image and enlarging it.
• Single SR Zoom :
Single SR Zoom expands the zoom ratio in a way that minimizes image deterioration.
The black letters "SR" are on the monitor screen while Single SR Zoom is selected.
• Multi SR Zoom :
Shoots a burst of High Speed CS images, which are then combined into a final image to suppress image quality deterioration.
The white letters "SR" are on the monitor screen while Multi SR Zoom is selected.
• Digital Zoom :
Digitally processes the center of the image to enlarge it.Remember that digital zoom causes deterioration of image quality.
Digital zoom is enabled (on) under initial factory default settings.
When the image size is 16M, zooming up to 18X optical zoom (36X in combination with Single SR Zoom, up to 36X in combination with Multi SR Zoom) is supported. When recording at VGA size, maximum zoom is 286.9X for optical zoom in combination with Multi SR Zoom and digital zoom.
To enable Single SR Zoom, select "Program Auto" as the recording mode. Next, on the REC MENU tab of the MENU, select "Single" for the "Zoom (SR)" setting. To shoot images with an appearance of even greater resolution, change the recording mode to "Multi SR Zoom".
Optical zoom, HD Zoom, and digital zoom can be used regardless of the current Single SR Zoom or Multi SR Zoom setting.
NOTE
• The value above the vertical red line on the zoom bar is the maximum optical zoom factor (including HD zoom).
In the case of Single SR Zoom and Multi SR Zoom, the value indicates the maximum zoom factor for the type of zoom being used. Values do not include digital zoom factors.
• The following functions are disabled when shooting with Single SR Zoom.
