Prime VS. Zoom Lenses
A Prime lens has a fixed focal length. These usually offer very sharp, distortion free images. The down side however is the need to change lenses frequently if a different focal length is required and carrying a large number of prime lenses is not usually practical. A zoom lens has a variable focal length. The ability to have a variety of focal lengths in one lens adds much convenience in that you will have to change lenses less frequently and won’t have to carry as much gear to capture a wide variety of photos. Some image quality may be sacrificed.
