The distance from the camera to the nearest plane of sharpest focus when the far plane of the depth of field is at infinity.
n. The distance at which you focus the lens for a landscape photograph to give maximum depth-of-field from infinity to a near point close to the camera. The hyperfocal distance depends on the focal length, aperture, and the size of the circle of confusion that the photographer decides on. One of the most handy tools for a landscape photographer is a hyperfocal distance calculator, a printed pin wheel type calculator that covers the photographers landscape lenses. _______________________________________________________
Using the depth of field principle, as a lens is gradually focused to farther subject distances, a point will eventually be reached where the far limit of the rear depth of field will be equivalent to "infinity." The shooting distance at this point, i.e., the closest shooting distance at which "infinity" falls within the depth of field, is called the hyperfocal distance. The hyperfocal distance can be determined as follows: Hyperfocal distance = f2 focal length F number minimum circle of confusion diameter • Thus, by presetting the lens to the hyperfocal distance, the depth of field will extend from a distance equal to half the hyperfocal distance to infinity. This method is useful for presetting a large depth of field and taking snapshots without having to worry about adjusting the lens focus, especially when using a wide-angle lens. (For example, when the EF 24mm is set to f/11and the shooting distance is set to the hyperfocal distance of approximately 1.5m/4.9ft, all subjects within a range of approximately 70cm/2.3ft from the camera to infinity will be in focus.)
The Hyperfocal Distance or point is the nearest point to the camera which is regarded as acceptably sharp when the lens is focused at infinity. So when the lens is focused on the hyperfocal point, depth of field extends from infinity back to a distance halfway between the camera and the hyperfocal point. This method is used in fixed focus viewfinder and 'box' cameras to obtain a photo that would perhaps include both a far away mountain range and a close group of people in acceptable focus. (see Depth of Field)
the distance in front of a lens that is focused at infinity beyond which all objects are well defined and clear
When your subject, foreground and background are at different distances it is often possible to adjust the focus to include all three when you take into account the effect of depth of field. The depth of field increases as the lens opening (aperture) is made smaller, and by shifting the focus off of the main subject you can make the foreground (or background) appear in focus as well. (See also depth of field) back to the
The distance setting on the focussing scale of a lens mount which will produce a sharply focussed image from infinity to half the distance of the focus setting at any specific lens aperture. Of particular value in stereo photography to ensure maximum 'depth of field', so that viewing is not confused by out-of-focus subject matter.
The nearest distance, h, at which a camera lens focuses the far distance (infinity). This gives the maximum depth of field; the nearest distance in focus is h/2.
Distance set on the focusing ring which will best use the depth of field for a particular shot.
Distance of the nearest object in a scene that is acceptably sharp when the lens is focused on infinity.
The distance to the nearest object in focus when the lens is focused on infinity. Setting the lens to focus on this distance instead of on infinity will keep the farthest objects in focus as well as extend the depth of field to include objects closer to the camera.
Technically, it is the distance between the camera and the hyperfocal point. But, in practice, Hyperfocal distance is a lens setting technique that allows you to shoot sharp pictures within a certain distance range without having to refocus. When the lens is focused on infinity, the hyperfocal distance is the distance of the nearest object in a scene that is acceptably sharp.
The hyperfocal distance is the point of focus where everything from half that distance to infinity falls within the depth of field.
The distance to the nearest plane of depth of field ( the nearest object in focus) when the lens is focused on infinity. Also the distance to the plane of sharpest focus when infinity is at the farthest plane of the depth of field. Focusing on the hyperfocal distance extends the depth of field from half the hyperfocal distance to infinity.
The hyperfocal distance is the distance from the camera such that if the camera is focused at that distance everything from infinity to half way between the camera and the hyperfocal distance is in focus. There is a page dedicated to hyperfocal distance here.
Hyperfocal distance is a distance used in optics and particularly in photography.
