Zoom lens, imaging device, and camera having imaging device

摘要: A zoom lens has a field view of 60° to 70° at wide-angle end, magnification change ratio about five six times, and small number component lenses, enables retraction compact size when not in use, provides high resolution, is compatible with compensation function for vibrations. Comprised are, order from an object side, first unit (G1) positive optical power, second (G2) negative third (G3) fourth (G4) power. When zooming the end telephoto move so as trace convex path toward image monotonously side.
