What is a prime lens?

Applicable Products and Categories of This Article

A prime lens is a lens that has a fixed focal length; it does not have any zoom capability. It is also sometimes referred to as a primary lens or a fixed focal length (FFL) lens. Prime lenses typically have a larger aperture for improved light gathering abilities and fewer elements for providing clearer, more accurately captured images.

NOTE:  All Sony® macro lenses are prime lenses.
