A head-up display includes a display device that displays an image toward a vertically downward direction, a first mirror that reflects the image to output reflected light toward a vertically upward direction, and a second mirror that reflects the reflected light from the first mirror to output reflected light toward a vertically upward direction. A vehicle includes the head-up display, and a windshield that reflects the reflected light emitted from the head-up display.

Head-up display and vehicle

A zoom lens system, in order from an object side to an image side, comprising: a first lens unit having positive optical power; a second lens unit having negative optical power; a third lens unit having positive optical power; a fourth lens unit having negative optical power; a fifth lens unit; and a sixth lens unit, wherein in zooming from a wide-angle limit to a telephoto limit at a time of image taking, the first lens unit, the second lens unit, the third lens unit, and the fourth lens unit move along an optical axis so that an interval between the third lens unit and the fourth lens unit at the telephoto limit is larger than that at the wide-angle limit, and wherein focusing from an infinity in-focus condition to a close-object in-focus condition is performed by moving the fourth lens unit along the optical axis.

Zoom lens system, imaging device and camera

An inner focus lens system comprising lens units each composed of at least one lens element, wherein a most object side lens unit is provided and is fixed with respect to an image surface in focusing, and the conditions: BF/Y&#x3c;1.7 and (L&#xd7;F)/f&#x3c;2.2 (BF: a distance from an image side surface apex of a most image side lens element to the image surface, Y=f &#xd7;tan &#x3c9;, L: an overall length of lens system, F: a F-number of lens system,f: a focal length of lens system, &#x3c9;: a half view angle of lens system) are simultaneously satisfied, or only the condition: (L&#xd7;F)/f&#x3c;2.0 (L: the overall length of lens system, F: the F-number of lens system,f: the focal length of lens system) is satisfied.
