Catercorner length), about 6~35 millimeters；Visual angle is more than standard lens, and about 53 ° or more until 220 °.Relative aperture generally compared with
It is small.Wide-angle lens generates after the fast direct light camera lens of 1860s occurs, and through various differentiation after this, has become photographic mirror
An important class in head.Modern wide-angle lens light group mainly has symmetrical structure and retreats focus type two kinds of forms of structure, right
Wide-angle camera lens is claimed to can be divided into two paratypes of positive outer lens and negative outer lens again.Wide-angle lens has focal length short, big excellent in visual angle
Point, can be in the broad scenery of closer distance coverage, and foreground is more prominent, and field depth is significantly more than standard lens, remote
Camera lens is taken the photograph, picture depth feelings are strong.Preferably it is used for the scenes such as indoor close-up photography, and shooting mountains and rivers, building, crowd.Old-fashioned wide-angle
Camera lens image field edge has the defect that illumination declines, novel wide-angle lens head majority image field illumination even.When using wide-angle lens close-shot,
Foreground is exaggerated, and more serious perspective distortion can be generated, and wide-angle lens is mounted on to the picture that can make broadcasting on projecting apparatus
It is more clear, but cumbersome when mounted, is easy to break part, therefore, a kind of convex eye wide-angle lens installation of projector is auxiliary
Help structure that will possess good market prospects.
