Optical apparatus, optical apparatus driving unit and camera system

An optical apparatus comprising:

• a zoom lens;
• a memory means for memorizing preset speed information and preset direction information;
• a memory instructing operation means to be operated for causing said memory means to memorize the preset speed information and the preset direction information;
• a drive instructing operation means to be operated for generating a drive speed command and a drive direction command for said zoom lens corresponding to the operation amount and the operation direction;
• and
• a control means for executing preset drive control on said zoom lens,
• wherein said control means is adapted, when said drive instruction operation means is operated and said memory instructing operation means is operated, to cause said memory means to memorize the drive speed command and the drive direction command of said zoom lens as the preset speed information and the preset direction information, and to drive said zoom lens with a speed corresponding to said memorized preset speed information and in a direction corresponding to said memorized preset direction information in response to the operation of control starting operation means while the drive instructing operation means is not operated.

An optical apparatus drive unit to be mounted on or connected to a main body of an optical apparatus including a zoom lens, the drive unit comprising:

• a memory means for memorizing preset speed information and preset direction information;
• a memory instructing operation means to be operated for causing said memory means to memorize the preset speed information and the preset direction information;
• a drive instructing operation means to be operated for generating a drive speed command and a drive direction command for said zoom lens corresponding to the operation amount and the operation direction;
• and
• a control means for executing preset drive control on said zoom lens,
• wherein said control means is adapted, when said zoom lens is driven and said memory instructing operation means is operated, to cause drive speed and the as the preset speed information, and to said memory means to memorize the actual drive direction of said zoom lens information and the preset direction drive said zoom lens. with a speed corresponding to said memorized preset speed information and in a direction corresponding to said memorized preset direction information in response to the operation of control starting operation means while the drive instructing operation means is not operated.
