Zeiss ZM 25/28mm Brightline Viewfinder
Recommended for 25mm and 28mm lenses
This optical finder is designed to demonstrate the perspective of 21mm lenses, which provide a wider angle of view than the Ikon's integrated rangefinder. Photographers can use this to check framing while the rangefinder can be used to confirm focus. Also, it easily attaches to the camera's hot shoe.
