Nikon Introduces New Fieldscope Digital SLR Camera Attachment FSA-L2

August 20, 2009

Nikon Vision Co., Ltd., a subsidiary of Nikon Corporation, is pleased to present Fieldscope Digital SLR Camera Attachment FSA-L2 for use exclusively with Nikon EDG Fieldscopes and Nikon D-SLR cameras.
The Digital SLR Camera Attachment FSA-L2, which has 3.5x zoom and 500-1,750mm (f/5.9-21) focal length, used together with the new EDG Fieldscopes enables super-telephoto shooting with Nikon D-SLR cameras. The D-SLR camera's Aperture-Priority Auto Mode can be used when the camera is connected to the FSA-L2 and EDG Fieldscope.
The new EDG Fieldscopes have been developed to provide excellent optical and mechanical performance, not only for observation but for digiscoping as well. The FSA-L2 features a bright optical path with fully multilayer-coated lenses. The combination of EDG Fieldscopes, the FSA-L2 and Nikon D-SLR cameras allows the capture of beautiful moments with high precision and superb image quality.

Combination example:
EDG Fieldscope 85 + FSA-L2 + D700

Key Features

  • Quickly and easily attaches directly to the F-mount of a Nikon digital SLR camera, for easy connection with an EDG Fieldscope
  • Multilayer coating is applied to all lens elements for brighter optics
  • Zoom function features an internal vari-magnification system, with magnification of 3.5x
  • Focal length ranges from 500mm to 1,750mm when attached to EDG Fieldscope 85/85-A
  • Compatible with camera exposure modes: Metered Manual Mode and Aperture-Priority Auto Mode
  • Exterior design and color synchronized to match digital SLR camera and EDG fieldscope

  • *The camera's autofocusing mode cannot be used. Focusing can only be done using the EDG Fieldscope focusing ring.
  • *When used with a Nikon DX-format digital SLR camera, the picture angle is equivalent to approx. 1.5x focal length of 35mm format.
  • *The actual f-number and the focal length vary depending on the actual zoom setting, while the camera display and image data show the constant f-number (13) and focal length (800mm).
  • *When used with a Nikon FX-format camera, vignetting occurs at focal length of between 500mm and 750mm with EDG Fieldscope 85/85-A and between 400mm and 600mm with EDG Fieldscope 65/65-A.
  • *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.
