What is 85mm?

The 85mm lens is a popular focal length for portrait photography, as it provides a flattering perspective for the subject. It is also commonly used in street, event, and sports photography. Different types of 85mm lenses are available, including prime lenses and zoom lenses, with various aperture settings. The 85mm lens is also renowned for its bokeh, or the quality of the out-of-focus areas in the image, which can be especially attractive for portrait photography.
