Description

Arrange structure of inside adjustment camera lens bayonet socket flange distance of camera lens in

Technical Field

The utility model relates to a camera technical field particularly, relates to a arrange structure of inside adjustment camera lens bayonet socket flange distance of camera lens in.

Background

The existing cameras on the market have certain difference in bayonet flange distance even for cameras of the same model due to irresistible factors such as processing errors, thermal expansion, cold contraction and the like, and the difference can cause the problems of inaccurate and uneven lens scales and the like in actual use, thereby greatly influencing the use effect. Usually, the user will compensate the flange distance by adding or subtracting a gasket on the bottom of the lens mount. The method generally needs more than 3 times of repeated lens assembly and disassembly, lens bayonet assembly and disassembly and gasket addition to confirm the effect, and the process is time-consuming and labor-consuming. When the adjusted lens is used for other cameras, the flange distance also needs to be adjusted again, and the working efficiency of a user is very influenced.

An effective solution to the problems in the related art has not been proposed yet.

SUMMERY OF THE UTILITY MODEL
