Especially in case of very small working distances of several centimetres, the calculated values are no longer realistic. The calculated working distances refer to the optic centre of the lens housing. By means of additional spacers, however, the lens distance can be reduced ("see calculation of close-up rings"). Driving distance by car is determined from the actual turn-by-turn driving directions. In case of F-mount lenses and other lenses for larger image circle diameters, the minimum lens distances are often considerably larger.
