An 85mm lens is a popular type of camera lens often used in portrait photography. It provides a natural perspective, allowing photographers to capture subjects with flattering proportions while maintaining a comfortable distance. This focal length is ideal for isolating subjects from their backgrounds, creating a pleasing bokeh effect. Typically, 85mm lenses come in both prime and zoom varieties, with prime lenses generally offering better image quality and wider apertures. The wide aperture allows for more light, making it easier to shoot in low-light conditions and achieve a shallow depth of field, which enhances the subject's focus.
