Abstract
An electronic view finder includes a display element that displays an image, and an eyepiece lens that is disposed on an eyepoint side of the display element and that is used for observing the image. The eyepiece lens consists of a first lens, a second lens having refractive power of a different sign from the first lens, and a third lens having positive refractive power in order from a display element side. Diopter is adjustable by moving at least one lens of the eyepiece lens. A television distortion of the image displayed by the display element varies depending on the diopter.
