Shortest distance from frontmost surface of the lens that can be brought into sharp focus. C# Kopiraj [Android.Runtime.Register("LENS_INFO_MINIMUM_FOCUS_DISTANCE")] public static Android.Hardware.Camera2.CameraCharacteristics.Key? LensInfoMinimumFocusDistance { get; } ...
如果该字段设置为 UNCALIBRATED,则相机系统无法进行可重复对焦,因此除了 0 为无限远和MINIMUM_FOCUS_DISTANCE为可以设置的最近焦距之外,设置没有合理准确的物理值。它可能仍然以屈光度为单位,但根本不是非常准确的。
So at one end of the scale, you’ll find the infinity symbol, and at the other end, you’ll find the lens’s minimum focusing distance (i.e., the closest the lens can focus). Check out the two lenses below. The distance scale on the 70-200mm (left) is under a cover, and you...

lens and on the distance between the lens and the object. The focal length of a lens is the distance from the centre of the lens to the point at which the image of a distant object is formed. A long-focus lens forms a larger image of a distant object, while a short-focus lens ...
Imagine being able to focus a lens without it changing in size. Nikon's IF technology enables just that. All internal optical movement is limited to the interior of the non-extending lens barrel. This allows for a more compact, lightweight construction as well as a closer focusing distance....
