7. TAKING PHOTOS AND VIDEO SHOOTING
Unit can be supplied with an optional adapter for photo/video cameras for night
photo/video shooting.
Night photo shooting can be performed by 35mm SLR cameras, with standard objective
lens (50-58 mm focus), such as Nikon, Canon, Pentax.
7.1 Attaching Unit to photo/video camera
ƒ
Screw the supplied adapter ring (52 mm or 37 mm diameter) in the objective lens
of your camera.
If the objective lens of your camera has another diameter for a light filter (for
example, 49mm or 58mm) use step-up or step-down adapter rings from the 52 mm
to your size. Such adapters are not supplied by Newcon; they are generally
available through camera stores.
ƒ Remove the eye cup (4, Fig.4) from the unit.
ƒ Set the eyepiece (1, Fig.4) in the middle position.
ƒ Screw the adapter ring (5, Fig.4) attached to camera into internal eyepiece thread.
ƒ Switch on the device and focus the assembled system with the help of the
objectives of the device and the camera.
If image cannot be focused detach the camera and turn the coupling of Unit’s
eyepiece a little. Assemble the system again and attempt focusing. At some
position of the eyepiece and objective of the camera the system will be focused.
ƒ Fasten the adapter ring with the camera to the body of the eyepiece of the unit with
three locking screws.
ƒ Turn Unit’s objective to focus the system while shooting.
ƒ Set diaphragm of the camera to 2.8 or 4 (shooting is possible at lower diaphragm
too, but the images will have lower quality). Taking photos with a fully opened
diaphragm is justified only when shooting quickly moving objects.
7.2 Diaphragm and shutter speed

shooting with the unit. If your camera is not equipped with the TTL system, the table
