An optimal zooming speed determining device includes: a storage to store a zooming speed at each position of a zoom lens; a tracking implementer to calculate a position of the zoom lens changed in a unit time at a zooming speed at each position of the zoom lens; a moving time calculator to calculate a difference between a position of a focus lens corresponding to a position of the zoom lens before the position of the zoom lens is changed and a position of the focus lens corresponding to the changed position of the zoom lens, and calculate a focus moving time by dividing the difference between positions of the focus lens by a highest moving speed of the focus lens; and a zooming speed determiner to reduce the zooming speed at each position of the zoom lens, if the focus moving time is greater than the unit time.
