Quora User, Digital photography since 2003... Optical zoom is a variable focal length lens, like a 15-85mm or 25-200mm lens. In an APS-C sensor DSLR camera, the standard or prime focal length is 35mm. Any focal length lower than this is called wide angle range. All the focal lengths above 35mm are called tele photo range.
Digital zoom is a function of a digital camera used to make the image seem more close-up. Digital zoom on a digital camera works the same as cropping and enlarging a photo in a graphics program. This type of zoom will result in a loss of quality and image resolution because the image is simply being enlarged without any extra details or pixels being added. Due to the quality of photos taken when using the digital zoom function, these photos may not be of good enough quality to print images larger than 4x6.
