Problems solved by technology

[0003] However, when a user actually shoots a scene with a high-magnification lens, since the field of view of the high-magnification lens is quite small, it is difficult for the user to judge the field of view only by the viewing window or viewing screen of the digital camera or the SLR camera itself. The location of the scope on the surface of the scene makes it difficult for the user to accurately move the field of view of the high-magnification lens to the predetermined shooting position on the surface of the scene

Embodiment Construction

[0023] Relevant technical content and detailed description of the present invention, cooperate accompanying drawing to illustrate as follows:

[0024] refer to figure 1 , which is the first preferred embodiment of the high-magnification lens with the field of view calibration function of the present invention, the high-magnification lens is mainly installed on an imaging device for high-magnification magnification of the microstructure on the surface of a scene shoot. As shown in the figure, the imaging device 10 can be a digital camera or a digital video camera, which has a built-in focusing lens (not shown). The high magnification lens 20 mainly includes a lens body 21 and a first scaler 22 . The magnification of the lens body 21 is a fixed predetermined magnification, and the predetermined magnification is between 10 times and 200 times.

[0025] Cooperate figure 2 As shown, the first standardizer 22 is mounted on the lens body 21. In this embodiment, the first standar...

Abstract

The invention provides a lens with high multiplying power, which is arranged on a camera head for shooting the surface of scenery and mainly comprises a lens body and a first designator, wherein, the lens body is provided with the range of depth of a field and a visual field range, the range of depth of the field can clearly shoot the surface of the scenery, and the visual field range is within the range of depth of the field and is arranged on the surface of the scenery; and the first designator is arranged on the lens body and can form a first light mark within the circumference of the visual field range in a projective manner so as to clearly indicate the visual field range so that a users can directly aim at the special surface area of the scenery to be shot in a visual manner so as to successfully shoot.

Description

technical field [0001] The invention provides a high-magnification lens, especially a high-magnification lens with the function of calibrating the field of view. Background technique [0002] Conventional high-magnification photography devices usually use a digital camera or a single-eye camera coupled with a fixed-magnification high-magnification lens body to magnify and photograph the surface microstructure of a scene. [0003] However, when a user actually shoots a scene with a high-magnification lens, since the field of view of the high-magnification lens is quite small, it is difficult for the user to judge the field of view only by the viewing window or viewing screen of the digital camera or the SLR camera itself. The location of the scope on the surface of the scene makes it difficult for the user to accurately move the field of view of the high-magnification lens to a predetermined shooting position on the surface of the scene. [0004] Therefore, based on the abov...
