FIELD: physics.
SUBSTANCE: optical adjusting device comprises an optical adjusting lens for stabilizing the image and autofocusing. The device includes a lens holder that supports the optical adjusting lens, at least, one electrodynamic (ED) image stabilization drive unit that moves the lens holder perpendicularly to the optical axis of the optical adjusting lens. Herewith the ED image stabilization drive unit includes a magnet with a neutral zone parallel to the optical axis and an ED automatic focusing drive unit that moves the lens holder in the direction of the optical axis. Herewith the ED of the automatic focusing drive unit includes a magnet with a neutral zone orthogonal to the optical axis.
EFFECT: increasing the accuracy of the position control during auto focus.
