Nikon Introduces Digiscoping Attachment FSA-L3 and DSA-N2, exclusively for MONARCH Fieldscopes

August 19, 2013

Nikon Vision Co., Ltd., a subsidiary of Nikon Corporation, is pleased to announce the release of Digiscoping Attachment FSA-L3 for Nikon digital SLR cameras, and Digiscoping Attachment DSA-N2 for Advanced Camera with Interchangeable Lenses Nikon 1 series. Both are exclusively for MONARCH Fieldscope Objective Lens Units and achieve prime focus shooting.

In prime focus shooting, light from the lens directly enters the image sensor; the image is not routed through a prism or eyepiece. This maximises lens resolving power, thus realising super-telephoto shooting with extremely high definition. Even the finest subject detail is shown with striking clarity. Users photographing a wild bird, for example, will marvel at the superb sharpness of every feather.

Digiscoping Attachment FSA-L3 Key Features

  • Digiscoping attachment connects with the F-mount of a Nikon digital SLR camera, realising prime focus shooting
  • Enables super-telephoto shooting at either 500mm focal length with a MONARCH Fieldscope Objective Lens Unit 82, or 400mm with a MONARCH Fieldscope Objective Lens Unit 60*
    • *When used with a Nikon DX-format digital SLR camera, the picture angle is equivalent to approx. 1.5x focal length of 35mm format
  • Optical compatibility with Nikon FX format realises full-size sensor shooting without vignetting
  • Optical design achieves aberration compensation effectively, while all lens surfaces are applied with multilayer coating
  • Using the Electronic Rangefinder, highly accurate focusing is attained even when focusing manually
    • *When attached to a Nikon digital SLR camera that employs an f/8-compatible AF sensor
  • Available exposure modes: A (Aperture-priority) auto and M (Manual)
    Available exposure metering: Centre-weighted metering

Digiscoping Attachment DSA-N2 Key Features

  • Digiscoping attachment enables use of an Advanced Camera with Interchangeable Lenses Nikon 1 series, realising prime focus shooting
  • Enables super-telephoto shooting at either 1,350mm* focal length with a MONARCH Fieldscope Objective Lens Unit 82, or 1,080mm* with a MONARCH Fieldscope Objective Lens Unit 60
    • *CX format
  • Attaching a lightweight Nikon 1 body, high-definition, super-telephoto shooting is easily performed
  • Optical design achieves aberration compensation effectively, while all lens surfaces are applied with multilayer coating
  • Available exposure modes: A (Aperture-priority auto) and M (Manual)
    Available exposure metering: Centre-weighted metering
