Adjustable Rack Focus Stop And Method Of Rack Focus
US Patent:
5758209, May 26, 1998
Filed:
Mar 24, 1997
Appl. No.:
8/823421
Inventors:
Ronald W. Rogers - Laguna Niguel CA
International Classification:
G03B 1318, G02B 702
US Classification:
396103
Abstract:
An adjustable rack focus stop on a focusing lens incorporates an arm mounted to the focusing lens housing and extending over the focus ring. A stop in the form of an adjustable band is positioned on the focus ring and includes a catch which is capable of engaging the arm. Two objects at different distances from the lens may be focused on through the focusing of the lens on the second object, adjustment of the stop so that it contacts the arm and then readjusting the focus to the first object. The two objects may be filmed in sequence without turning off the camera by adjusting the focus to engage the catch with the arm when refocusing to the second object.
