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 ). Test
eyepiece correction lenses before purchase to ensure that the desired
focus can be achieved. Use eyepiece correction lenses only if the desired
focus cannot be achieved with the built in diopter adjustment control
(–3 to +1 m
–1 ). The rubber eyecup cannot 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.
• 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).
