Viewfinder eyepiece accessories • DK-20C Eyepiece Correction Lenses: Lenses are available with diopters of -5, -4, -3, -2, 0, +0.5, +1, +2, and +3 m-1 when the camera diopter adjustment control is in the neutral position (-1 m-1). Use eyepiece correction lenses only if the desired focus can not be achieved with the built in diopter adjustment control (-2 to +1 m-1). Test eyepiece correction lenses before purchase to ensure that the desired focus can be achieved. The rubber eyecup can not be used with eyepiece correction lenses. • DK-21M Magnifying Eyepiece: The DK-21M magnifies the view through the viewfinder by approximately 1.17× (50 mm f/1.4 lens at infinity; -1.0 m-1) for greater precision when framing. • DG-2 Magnifier: The DG-2 magnifies the scene displayed in the center of the viewfinder for greater precision during focusing. Eyepiece adapter required (available separately). Note that because the DG-2 interferes with the eye sensor, you may find it necessary to select Off for the Info display auto off item in the setup menu (0 130) when this accessory is attached. • DK-22 Eyepiece Adapter: The DK-22 is used when attaching the DG-2 magnifier. • DR-6 Right-Angle Viewing Attachment: The DR-6 attaches at a right angle to the viewfinder eyepiece, allowing the image in the viewfinder to be viewed at right angles to the lens (for example, from directly above when the camera is horizontal). In addition, because the DR-6 interferes with the eye sensor, you may find it necessary to select Off for the Info display auto off item in the setup menu when this accessory is attached.
