Fieldscope Digital SLR Camera Attachment FSA-L1

Transform your Fieldscope into a 1,200mm* or 1,500mm* super-telephoto lens for Nikon digital SLR cameras and take spectacular closeup images.

  • *35mm-format equivalent

Specifications

Dimensions (without cap and screw): ø62 x 143mm
Weight: Approx. 320g

Features

  • Allows use of the camera's Centre-Weighted and Spot metering systems
  • Matrix metering can be used with Nikon D2 series
  • Allows use of the camera's Aperture-Priority Auto and Manual exposure modes
  • Attaches directly to the Fieldscope and the F mount on a Nikon Digital SLR camera.
  • Note:
    • Because the optical system has different characteristics from ordinary interchangeable lenses, when the FSA-L1 and Fieldscope are used for shooting with an SLR camera, exposure may vary with the camera model. With a digital SLR camera, confirm the exposure indication in the external LCD and use exposure compensation if necessary.
    • Camera's autofocusing mode cannot be used. Perform focusing using the Fieldscope focusing ring.


Combination example:
Fieldscope ED82+FSA-L1+D70

About film SLR cameras:
Usable models: F6, F5, F100, F65, F55, FM10, FE10

  • With F80, F75, FM3A, user must determine the exposure; Nikon does not recommend using these models.
  • With any of the above models, slight vignetting may occur at the periphery of the image.

Compatible Fieldscope models:

Fieldscope ED82/Fieldscope ED82 A
Fieldscope III/Fieldscope III A
Fieldscope EDIII/Fieldscope EDIII A

  • Note:
    • We strongly recommend using an ED-type model, which employs ED glass to minimize chromatic aberration and keep images sharp.
    • ED78 series, II series and I series can also be used (I series can be used only with 24x/30x Wide MC and Fieldscope Digital SLR Camera Attachment FSA-L1).
    • We do not recommend connecting the FSA-L1 with the Fieldscope ED50/50 A because this combination may be physically imbalanced in actual use and could compromise product integrity.

F-number and focal length in combination with Fieldscope and digital SLR camera

Fieldscope Selector settings*1 F-number Focal length (35mm equivalent focal length)*2
ED82/ED82 A A 13 1,000 (1,500) mm
III/III A/II series/I B 800 (1,200) mm
EDIII/EDIII A/EDII series/ED C 800 (1,200) mm
ED78/ED78 A D 1,000 (1,500) mm
  • *1Depending on the Fieldscope model used, by setting the selector on the body of the FSA-L1, F-number and focal length data will be transmitted to the camera.
  • *2The picture angle of 35mm-format SLR cameras differs from that of digital SLR cameras due to the difference in the size of captured images. 35mm equivalent focal length is 1.5x (2x for High-Speed Cropped Image of the D2X) of the focal length of the lens used.
