The Nikon Right-Angle Viewing Attachment DR-4
screws into the finder of any Nikon or Nikkormat
35mm SLR camera capable of accepting screw-in
eyepiece accessories (see table for specific
models and finder types). With this attachment,
the viewfinder image is viewed at right angles (via
the built-in roof prism) to the camera’s optical
axis—a feature that is very convenient when
shooting from low (or high) viewpoints, or when
normal finder viewing is difficult, as in close-up
work or photomicrography. The DR-4 is fitted with
a prism to maintain the image unreversed and
erect. Also, the reproduction ratio is 1:1, with
100% of the viewfinder image is visible. DR-4
features a built-in diopter adjustment ring that
allows you to adjust the dioptry from +4 to -4.
When attached to a camera with a regular diopter
setting of -1, the dioptry can be adjusted from +3
to -5. Weight of the DR-4 is approximately 110g.
Attaching to the Camera
The attaching procedure differs depending on the
type of camera or finder in use. Before attaching
the DR-4, make sure that all eyepiece accessories
such as the protective finder eyepiece unit of the
Nikkormat rubber eyecup, etc., are removed, then
refer to the table for correct mounting procedure.
Note that once the DR-4 is securely mounted on
the camera, it can be rotated (i.e., moved side to
side) for placement at the most convenient
viewing position.
Note: It is impossible to mount the DR-4 on earlier Nikon F
model cameras because of their rectangular eyepiece frames.
Eyepiece Adjustment
To adjust the DR-4 to your eyesight, look through
the attachment and turn the diopter adjustment
ring until the image on the focusing screen
appears sharp and crisp. When the white line on
the body of the DR-4 and the white dot on the ring
are aligned, the combined dioptry of the camera’s
viewing system is -1. Note that the DR-4 is
provided with a locking screw to secure the
diopter setting; be sure to loosen this screw before
attempting to make adjustments.
