Digiscoping Adapter DSA-N1 (exclusively for Nikon 1 Series)

Adapter for digiscoping which connects a Nikon 1 body to a Nikon Fieldscope with an eyepiece, enabling super-telephoto shooting

Specifications

Dimensions (without cap and projections): ø68 x 58mm
Weight: 180g

Features

  • Adapter for digiscoping which connects a Nikon 1 body to a Nikon Fieldscope with an eyepiece, enabling super-telephoto shooting
  • Attaches directly to the Nikon 1 mount
  • Attaches to a Nikon Fieldscope easily, since optical axis adjustment is not required
  • Allows use of the camera's A: Aperture-priority auto and M: Manual exposure modes
  • Easy-to-carry compact size
  • Compatible with various eyepieces, and capable of super-telephoto shooting at various focus range settings
  • Note:
    • Incompatible with Smart Photo Selector mode and Motion Snapshot mode
    • The camera's A: Aperture-priority auto and M: Manual exposure modes only are recommended when shooting.
    • Depending on the type of camera and eyepiece, illumination fall-off and shadows may occur at the peripheries
    • 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
    • Camera's autofocusing mode cannot be used. Perform focusing using the Fieldscope focusing ring.
    • The actual F-number and the focal length vary depending on your choice of combination of Fieldscope and eyepiece, while the camera display and image data show the constant F-number (6.3) and focal length (540mm)

Calculation of composite focal length
[Composite focal length] = [Magnification of eyepiece] x [Focal length of DSA-N1 (18mm)]
(35mm format equivalent focal length is 2.7x of the composite focal length)
<Examples>
[540mm] = [30x] x [18mm]
(In this case, the 35mm format equivalent focal length is 540mm x 2.7=1,458mm)
Calculation of composite F-number (theoretical value)
[Composite F-number] = [Magnification of eyepiece] x [Focal length of DSA-N1 (18mm)] ÷ Objective diameter of Fieldscope
<Examples>
[F6.4] = [30x] x [18mm] ÷ [85mm]
