What lens does a SLR portrait use?

SLR portraits recommend 50mm or 85mm fixed-focus lenses. You can use the aperture priority file to control the depth of field and take photos with bright themes and soft backgrounds. Turn the camera mode dial to Av file and set the aperture value. It is best to shoot portraits with a fixed-focus lens with a large aperture, shoot with the maximum aperture of the lens, and then gradually narrow the aperture, and the best image has been obtained.

Single-lens reflex camera, also known as SLR camera, refers to a camera that uses a single lens, through which light shines on the reflector and takes a view through reflection. The so-called "single lens" means that the photographic exposure light path and the framing light path * * * use one lens, unlike the paraxial camera or the double-reflex camera, the framing light path has an independent lens. "Reflection" means that the plane mirror in the camera separates the two optical paths. The first SLR camera was developed by 1909. Since 1970s, this technology has been widely used, and SLR cameras have become the new favorites of senior photographers and professional photographers.
