ACCESSORY, CONTROL METHOD, AND STORAGE MEDIUM

原文（中文）

An accessory for use with an image pickup apparatus includes a first drive unit for moving a first movable member, a second drive unit for moving a second movable member, one or more memories storing instructions, and one or more processors that, upon execution of the instructions, operate to control power used for driving the first drive unit and the second drive unit. In a case where an orientation of the accessory changes from a first orientation to a second orientation, power used for driving one of the first drive unit or the second drive unit increases while power used for driving the other of the first drive unit and the second drive unit decreases. The one or more processors operate to change an upper limit value of the power used for driving the first drive unit and second drive unit based on the orientation of the accessory.
