Understanding the zoom on a digital camera would be very confusing for ordinary users. specific information will be found in the camera, such as megapixels and display size.

However, the zoom is something that is not so much on the informed use. Therefore, most buyers do not pay attention to the camera they bought. In fact, the zoom camera can have a big impact on the quality of your image.
Usually, there are two types of zoom on digital cameras are optical and digital. Here is information that will be helpful to explain how to work with one another and which are best suited to your needs.

Optical Zoom

Optical zoom function to measure the change in focal length (distance between the center of the lens and image sensor) from the lens. for example, if you move the camera lens away from the image sensor, the sensor captures decrease in the number of subjects and images will be enlarged, which resulted in increased zoom.

If your camera has optical zoom, you will have full control over zoom, where he will stop (known as smooth zoom.) However, on many digital camera zoom settings are limited, which only offer between four and seven times zoom.

Digital Zoom

Digital zoom is the process when the photographs digitally cropped and enlarged. Usually, this is achieved by increase or decrease the pixel, which will reduce image quality. Therefore, only two types of zoom, and only suitable in certain circumstances.
Often you can perform a digital zoom on the stage after shooting is completed, which will allow you to control image quality. If you do not have access to photo editing software, then you should take a picture with high resolution when using digital zoom, so image quality can still be maintained.

What is Zoom?

When buying a digital camera, you’ll see a measurement of the zoom on the camera side marked “x.” The higher the amount, the greater the ability to zoom. For example, a much written 10x magnification greater than 3x.
However, not all measurements 10x optical zoom, this camera is the same. Manufacturers measure the camera lens and multiplier or “x” which represents the difference between the largest and smallest measurement. For example, a camera with a magnification of at least 45mm, has a 10x optical zoom, it will make a maximum magnification of 450mm.
Often, manufacturers of digital cameras will incorporate the measurement of optical and digital zoom to show the number on the front of the box with the camera. Most of this data is not accurate, so it is important for you to read the small number of optical zoom.
When looking at zoom digital camera, you should do some research to make sure the camera that provides an enlarged image with good quality.
