发明名称 Lens barrel and imaging apparatus
摘要 An optical apparatus includes a focus adjustment unit which controls a focusing lens such that the focusing lens is driven to an in-focus position using a signal obtained by photoelectric conversion of an image of an object, the image being formed by an optical system including the focusing lens; and a color temperature detection unit which detects a color temperature of the object. The manner in which the focusing lens is driven differs depending on the color temperature.
