Many times when we are going to buy a camera we are confused which zoom is better digital or optical? There are also some other zoom features are available but they are nothing but only some sort of extension or mixing of both of these zoom features.
Digital zoom
Digital zoom is not a true zoom.The idea behind digital zoom is that it takes a selected portion of image is expanded to the full size of image.It is similar to what we does in a software program to enlarge a image.
This is because in digital zoom camera lenses stay the same.
Use Of Digital zoom
People who do not use computers or the image editing softwares can find digital camera useful. If u do not need an image to be printed you can go with these .The final reason is that you can spot the subject little easier by zooming..
Optical zoom
Optical zoom is the true zoom. It uses lenses within the camera to bring the image closer.It is similar to binocular or similar instruments.When using optical zoom quality of the image remains same and the full resolution of camera is used.The levels of zoom is varied by varying the lens distance in the camera.
Use Of Optical zoom
To view the real good pics use optical camera .If u have to take print of the image you have to definitely go for optical camera only.It is the real zoom.
There are some other zoom features are also available like smart zoom ,intelligent zoom which are nothing but the efficient extensions of Optical and Digital zoom.
