Note:
·
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.
·
Camera's autofocusing mode cannot be used. Perform focusing using the EDG Fieldscope focusing ring.

When used with a Nikon FX-format camera,
vignetting occurs at focal lengths between 500mm and 750mm with EDG
Fieldscope 85/85-A and between 400mm and 600mm with EDG Fieldscope
65/65-A.
