• Diopter-adjustment viewfinder lenses: To accommodate
individual differences in vision, viewfinder lenses are
available with diopters of –3, –2, 0, +1, and +2 m
–1
(values
with camera diopter control centered at –1 m
–1
). Use
diopter adjustment lenses only if the desired focus can not
be achieved with the built-in diopter adjustment control (–3
to +1 m
–1
). Test diopter adjustment lenses before purchase
to ensure that the desired focus can be achieved. The
DK-17C is equipped with a safety lock.
• Magnifying Eyepiece DK-17M: The DK-17M magnifies the view
through the viewfinder by approximately 1.2
×
for greater
precision when framing.
• Right-Angle Magnifying Viewing Attachment DR-5/Right-Angle Viewing
Attachment DR-4
: The DR-5 and DR-4 attach to the viewfinder
eyepiece at a right angle, allowing the image in the
viewfinder to be viewed from above when the camera is in
the horizontal shooting position. The DR-5 can also magnify
the view through the viewfinder by 2
×
for greater precision
when framing (note that the edges of the frame will not be
visible when the view is magnified).
• Eyepiece Adapter DK-18: The DK-18 is used when attaching the
DG-2 Magnifier or DR-3 Right-Angle Viewing Attachment to
the D3.
