Digiscoping Bracket DSB-N1 (exclusively for Nikon 1 Series)

Bracket for digiscoping which connects a Nikon 1 camera with a 1 NIKKOR lens and Nikon Fieldscope with an eyepiece, enabling super-telephoto shooting

Specifications

Dimensions (without projections) (when configured at its minimum size): 101 (W) x 106 (H) x 127 (D) mm
Weight (without accessories): 270g

Features

  • Bracket for digiscoping which connects a Nikon 1 camera with a 1 NIKKOR lens and Nikon Fieldscope with an eyepiece, enabling super-telephoto shooting
  • Includes a cable release (approx. 50cm) to prevent camera shake when shooting; the cable release socket is attached to the Bracket
  • Includes a light-shielding rubber sheet to prevent external light from entering
  • Precautions:
    • Depending on the type of camera and eyepiece, vignetting and shadows may occur
    • Carefully adjust the optical axis so that vignetting and shadows are minimized. Vignetting and shadows may not completely disappear.
    • Noise in the form of lines may appear in pictures depending on the shooting condition
    • Because the optical system characteristics differ from those of ordinary interchangeable lenses, the exposure level may vary depending on the camera model; use exposure compensation if necessary. Exposure compensation may be required when zoom is set at a wider position.
    • When replacing batteries or recording media, the camera may or may not need to be removed from the connected equipment depending on the camera
    • If you notice external light on the LCD monitor or taken image, use the supplied light shielding rubber sheet or a black cloth to prevent light entering between the mount and lens attached to the camera

Calculation of composite focal length
[Composite focal length] = [Magnification of eyepiece] x [Focal length of 1 NIKKOR lens]
(35mm format equivalent focal length is 2.7x of the composite focal length)
<Examples>
[300mm to 900mm] = [30x] x [10mm to 30mm]
(In this case, 35mm format equivalent focal length is 300mm to 900mm x 2.7 = 810mm to 2,430mm)
Calculation of composite F-number (theoretical value)
[Composite F-number] = [Magnification of eyepiece] x [Focal length of 1 NIKKOR lens] ÷ Objective diameter of Fieldscope
<Examples>
[3.5* to 10.6] = [30x] x [10mm to 30mm] ÷ [85mm]
  • *Although the theoretical number obtained using the calculation above may exceed the 1 NIKKOR's F-number, the actual F-number will not.

  • Note:
    • Depending on the type of camera, its position, or zoom setting, vignetting and shadows may occur. Carefully adjust the camera position so that vignetting and shadows are minimized.
    • Pay special attention when the camera is set at a wide-angle position, because the camera lens may hit against the eyepiece when zooming in to the telephoto side
