Description

Adjustable dimming polarized lens

The invention provides an adjustable dimming polarized lens, which mainly positions the camera lens when connecting at least two functional lenses, can use the same group of functional lens units to cooperate with multiple camera lenses for rapid positioning at any time, and is working The adjustment of the functional lens is to obtain the required polarized light or dimmed light by turning the outer periphery of the lens unit with the hand.

Existing cameras are used to obtain the expected situation of the scenery or people pre-photographed at the time of the photo (such as: showing the feeling of gradual rendering, or showing the atmosphere of the season at that time, or showing the sky of the shooting time...). The front of the lens of the camera is combined with an adapter unit to set up the preset functional lenses required in a timely manner, so that the photos taken meet the desired feeling.

And the adapter unit integrated in front of the camera lens is usually connected in a thread form, resulting in the tightness between the components after a period of use is no longer as urgent as the original, and the form of the twist lock If any functional lens between the adapter unit is to be rotated azimuthally, if the restricted frame and the adapter ring are rotated, the tight state cannot be maintained, resulting in the functional lens combined between the adapter unit usually cannot be oriented change.

Therefore, the inventor of the present case has previously made improvements to the problems existing in the replacement of the preset function of the camera lens and the use of placement and positioning, and proposed a specific solution and disclosed it on 2017.11.21 Certificate number: M552111 "Camera lens positioning structure" new In this case, the positioning of the lens here is adopted: the at least one or more functional lenses that must be expected to be connected are adsorbed by the magnetic element and the resisting member on the side of the adjacent frame to achieve the exact orientation, so that even after a period of use It can still maintain the urgency of mutual restraint. If the functional lens connected to the side of the lens needs to be rotated azimuthally, it is only necessary to drive the frame adsorbed on the side of the adjacent resisting member to rotate to synchronize. The application of this functional lens is combined with motorized orientation adjustment, so that the photos taken can reach the expected situation.

The above-mentioned functional lens combined on the side of the camera lens can indeed achieve quick positioning and convenient adjustment of azimuth dialing; the inventor of the present case is for the same type of camera lens to connect at least two The positioning of the functional lens can be implemented by another group to achieve the same group of functional lens units. It can be quickly positioned with multiple camera lenses, and the adjustment of the functional lens can be obtained by turning the outer periphery of the lens unit with the hand. Polarization and/or dimming if necessary.

The present invention is based on the certificate number of the previous application: M552111 "Camera lens positioning structure" The new case of functional lens connection means is used as another implementation method to extend the same group of functional lens units can be combined with multiple The camera lens is quickly positioned, and this functional lens unit can be adjusted by hand to get the required polarized light or dimming.
