Digital zoom significantly reduces the quality of the photo. If your camera does not include digital zoom you can always shoot the photo without zooming and then use a PC photo editing software to crop a portion of it and enlarge the rest. In fact using PC software is always the preferred method to built-in digital zoom since it allows you to try different zoom sizes, different zoom areas and different zoom algorithms while not losing the original photo. So which one is better?

Optical zoom is superior to digital zoom. In fact from a practical point of view digital zoom should not be considered zoom at all. It is always better to apply digital zoom on a PC at a later time rather then when taking the photo using the camera’s built-in digital zoom. When using a PC different sizes can be used and different zoom algorithms that can result in better qualities.

Know your camera's zoom
Some manufacturers claim the maximum zoom figure their cameras support without specifying if it is optical or digital zoom. This information is confusing as many consumers do not understand the difference between the two. For example if a camera supports a 5X optical zoom and 10X digital zoom advertising the camera as a “10X zoom camera” is confusing – 10X digital zoom can be done with any camera using simple PC software.

- When buying a camera always make sure that you know what the optical zoom figure is and that it meets your needs. Ignore the digital zoom figure as it does not mean much and can not compensate for a camera with poor optical zoom.
