Document Type and Number:
Japanese Patent JP2019023683
Kind Code:
A
Abstract:
To solve the problem in which: in an imaging device including a converter lens, sunlight and the like is condensed on an imaging element and the imaging element is burned even when an interchangeable lens is not attached to the imaging device.SOLUTION: An imaging device 1 arranges a first polarization filter 105 and a second polarization filter 106 between a lens mount part 101 and an imaging element 110 and on an optical axis 149. The first polarization filter 105 is rotated in mechanical linkage to attachment/detachment rotation operation of an interchangeable lens 2. The imaging device 1 can thus attenuate light entering the imaging element 110 and can prevent burning of the imaging element 110.SELECTED DRAWING: Figure 4b
