A variable power lens, having first and second lens groups, includes first and second lens group support frames, a linear guide ring, first and second lens group drive rings which rotate to move the first and second lens group support rings in the optical axis direction relative to the linear guide ring, a drive ring coupler which couples the first and second lens group drive rings with each other to prevent relative rotation therebetween while allowing relative movement therebetween in the optical axis direction; and a drive-ring movement controller which integrally rotates the first and second lens group drive rings via the drive ring coupler without relatively moving in the optical axis direction when a power-variation operating member is operated, and moves one of the first and the second lens group drive rings in the optical axis direction without rotating when a focus operating member is operated.
