Close-up lens



Close-up lens
A close-up lens is used to shorten the M.O.D.of the master lens for close-up shooting.
The maximum object distance becomes the focal length of the close-up lens.
The minimum object distance is calculated by the following formula.

New minimum object distance = fc x S / (fc + S)

fc= Focal length of the close-up lens

S= M.O.D.of the master lens
