Having the right camera lens is incredibly important. The correct lens will maximize the video quality of your camera (a very important consideration for higher megapixel cameras) and adjust for your specific environmental factors.
There are several lens types to choose from that offer different fields of view. With a fixed lens only one field of view is possible such as normal, telephoto, or wide angle. A varifocal lens allows you to manually adjust the lens to the field of view you want within a range of available focal lengths. Day/night and auto-iris lenses adjust for varying lighting conditions.
