An 85mm lens is a popular focal length used in photography, particularly for portraiture. It provides a natural perspective, allowing photographers to capture subjects with flattering proportions while maintaining a comfortable distance. This lens is often favored for its ability to create a pleasing background blur, known as bokeh, which helps to isolate the subject. Typically, 85mm lenses come in both prime and zoom varieties, with prime lenses generally offering superior image quality and wider apertures. They are compatible with various camera systems, including DSLRs and mirrorless cameras, making them versatile tools for both amateur and professional photographers.
