Digiscoping Attachment FSA-L3 (exclusively for MONARCH Fieldscope Objective Lens Unit)
Specifications
Length x diameter: 106 x 69mm
Weight: 255g
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

- Camera's autofocusing mode cannot be used. Focus manually using the focusing ring of the MONARCH Fieldscope Objective Lens Unit.
- Camera's exposure meter activates even in Manual exposure mode.
- 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 camera display and image data show the constant f-number (13) and focal length (800mm).
- 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.
