| 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 |
