Abstract
An image pickup apparatus that is capable of changing a zoom speed in a wide range in accordance with an amount of movement of a zoom lever without oversizing the zoom lever, and has excellent operability of the zoom lever. An amount of change of zoom speed relative to an amount of movement of the zoom lever during when the zoom lever is operated from a first neutral position in a first or second direction differs from that during when the zoom lever is operated from a second neutral position in the first or second direction. Thus, the zoom speed can be varied in a wide range according to the amount of movement of the zoom lever, while ensuring the operability of the zoom lever.
