Fivercam Wiki information:
What type of lenses are there? DSLR and Mirrorless cameras have either full-frame or crop sensors. While full-frame lenses can be used on a crop sensor, a lens designed for a crop sensor cannot be used on a full frame. Camera lenses can be broken down into two main types, zoom lenses and prime lenses. Zoom lenses are one of the most common types of lenses that you will need. While Prime lenses have a fixed focal range, which means that you cannot zoom in or out. They are perfect for portraits or landscape photography. The other lens types are fisheye for abstract photography, wide angle for landscape and architecture, standard lenses and short telephoto lenses for street, travel and portrait, medium telephoto for sports, wildlife, action, super telephoto for sports from a distance, nature and astronomy and macro for close-up shots.
