A viewfinder eyepiece for a camera having a video signal tap, particularly a professional high definition video camera, for viewing the display screen of a display device, such as a CRT, in the viewfinder. The eyepiece includes a negative powered lens on an optical axis and positioned adjacent the display screen, a first positive powered lens on the optical axis is spaced from the negative powered lens is located at an eye-viewing end of the eyepiece, and a second positive powered lens positioned on the optical axis between the negative powered lens and the first positive powered lens. The second positive lens is mounted in the eyepiece to be movable along the optical axis in the space between the negative powered lens and the first positive powered lens for adjusting the focus on the display screen through the eyepiece. The combined display device and eyepiece module is releasably connected to the rest of the viewfinder and extensions can be installed for modifying the view position without affecting the image viewing through the eyepiece.
