Digital Cameras High Optical Zoom
Digital versus optical zoom in camcorders: How do they work side by side?
I understand that a high optical zoom (when used) provides a clear picture while a high digital zoom (when used) provides a clear picture. What I want to know is, do these 2 different characteristics dependantly or work independently of each other? There are camcorders that come with both optical zoom high and low digital zoom at the same time? Or to have a optical zoom High inevitably impose the camera with a high digital zoom? And if this is the case sad but true, the digital zoom can be deactivated during shooting, leaving active only optical zoom, so that the optical zoom is done digitally, rather than because of the capture of a clear and well defined picture, instead of an image, fuzzy pixelated? For same reason, only for purposes of knowledge, the optical zoom can be turned off leaving active only the digital zoom?
Typically, the optical zoom be used 1 until it has reached the upper limit, the digital zoom takes the moment. Thus, the digital zoom is another addition to optical zoom. Here's a good explanation zoom digital: http://www.dpreview.com/learn/?/Glossary/Digital_Imaging/Digital_zoom_01.htm
