Abstract

An adjustable dimming polarizing lens is such that a functional lens unit is connected to a side of a camera lens. The functional lens unit includes an A frame, a B frame, and a C frame. The A frame and the B frame are respectively disposed with a first polarizer and a second polarizer in a concave area on one side, and are each screwed with a pressure ring for position constraint. The B frame is allowed to dispose in a concave receiving area on a side of the C frame, such that an outer periphery of the B frame is partially exposed through notches formed on two sides of a circumference of the C frame and movability of the B frame as being disposed inside the C frame can be set within a limited area of a preset range. A magnet provided in a preset form is combined on an inner side of the C frame. The functional lens unit so formed can be connected to an adapter ring on the side of the lens for rapid magnetic positioning by the adjacent magnetic recessed area, and pre-adjustment of the functional lens unit can be performed by moving the C frame/or the exposed outer periphery of the B frame, so as to obtain the required polarization/dimming.

Description

Adjustable dimming polarized lens

The present invention provides an adjustable light-reducing polarized lens, which is mainly used to position the camera lens in connecting at least two functional lenses. The same group of functional lens units can be used to coordinate multiple camera lenses for rapid positioning at any time. The adjustment of the functional lens is to obtain the necessary polarized light and/or light reduction by moving the outer periphery of the lens unit with the hand.

Existing cameras will capture the scenes or characters that were pre-photographed at the time when taking pictures (such as presenting a gradually rendered feeling, or presenting the atmosphere of the current season, or presenting the sky of the shooting time...). The front of the camera lens is combined with an adapter unit to set up the required preset functional lenses in a timely manner, so that the shots can meet the desired feeling.

However, the adapter unit integrated in the front of the camera lens is usually connected in a threaded form, resulting in the tightness between the components and the components after a period of use is no longer as urgent as the original, and the twist lock form If any functional lens between the adapter unit is to be rotated in orientation, the restricted lens frame and the adapter ring cannot be kept in close contact if they rotate. As a result, the functional lens combined between the adapter unit usually cannot be oriented. change.

Therefore, the inventor of the present case has previously addressed the problems that exist in the replacement of the preset functions of the camera lens at any time, and the problem of the placement and positioning of the camera lens to improve, and propose a specific solution that can be solved and disclosed on 2017.11.21. Certificate No.: M552111 "Camera lens positioning structure" new In this case, the lens positioning here is adopted: for at least one or more functional lenses that need to be connected to the expectations, the magnetic absorption element and the resisting part on the side of the adjacent frame are used to adsorb in the exact direction, even after a period of use It can still maintain an urgent mutual restraint. If the functional lens attached to the side of the lens needs to be rotated, it can be driven synchronously by driving the frame attached to the side of the adjacent resisting member to rotate. This functional lens has both mobile orientation adjustment in application, so that the photos can reach the expected situation.

The above-mentioned functional lens combined on the side of the camera lens for orientation connection can indeed achieve rapid positioning and easy adjustment of the orientation dial; here the inventor of the present case is aiming at connecting at least two types of camera lenses in the same category.
