I often got see about this digital and optical zoom in camera and handphone advertisements.But to tell the truth i often think that both got similar functions and assume that the optical zoom was old technology and the digital zoom was new technology.This perception was totally wrong and now i got to know that optical and digital zoom are actually two different things.So today i just share a little bit about my finding to you guys.

        Whenever we want to take a picture we often think that a higher megapixel camera got a nice picture clarity.Well that seems correct ( the higher the megapixel,the higher the picture clarity ).And sometimes we do find like 2MP with 3x zoom and 8MP with 2x zoom.Well in this case a few of us could get easily confused by these terms.Actually the difference is the multiple times of zooming and the quality.You will get a 2MP resolution picture with every zoom and the same goes for the 8MP resolution.In terms of quality you will find that 8MP has a much clearer picture regardless the zoom because the resolution is high enough.

        Now let's go into our subject.Optical zoom actually zoom in your picture to cater your needs.It ensures that the resolution of your zoomed picture is the same as the resolution specified for the particular camera.Whereas the digital zoom will crop the picture and expand it.In this case the picture quality will be lesser.Normally we can see this if we zoom the picture through handphone.The clarity of the picture will be much affected.

        Its better if we take the picture with the optical zoom and edit it with photoshop or other easily available softwares.The main purpose of digital zoom is can be said for those who really not so good at picture editing softwares and opt to crop it staright from the camera itself.

       So if whenever we want to compare a camera means we should compare it with the optical zoom of the camera.We will not find any difference if we just compare it with the digital zoom.
