What is 85 mm?

The 85mm lens is a popular choice for portrait photography. It produces a shallow depth of field and flattering compression of facial features. It is also commonly used for street photography, as it allows the photographer to remain at a comfortable distance from their subject while still capturing intimate moments. The 85mm lens can come in various types, such as prime (fixed focal length) or zoom lenses. It is compatible with most camera systems, but may have varying focal lengths depending on the camera sensor size.
