<p>A zoom lens includes a most object-side lens unit (G1) remaining fixed on the optical axis when the magnification of the zoom lens is changed and a focusing operation is performed; a most image-side lens unit (G4,G5) remaining fixed when the focusing operation is performed; and a plurality of moving lens units (G2,G3) lying between the most object-side lens unit and the most image-side lens unit, moved along the optical axis when the magnification is changed. The most object-side lens unit (G1) includes, in order from the object side, a negative lens component (L1,1), a reflective optical component (R1) having a reflecting surface for bending the optical path, and a positive lens component (L1,2). The most image-side lens unit has at least one aspherical surface. An electronic imaging device includes an electronic image sensor located on the image side of the zoom lens.</p> |
