Description
Technical field
The utility model relates to photography, equipment technical field is used in shooting, relates in particular to a kind of filter support, the camera lens that comprises this filter support and picture frame assembly.
background technology
Photography on current market, shooting filter are conventional photography and vedio recording annexes, and it is tightly locked in the front end of photography and vedio recording camera lens by screw thread.The photographic effects that photography, shooting filter are mainly used in interception ultraviolet ray, len and cannot adjust for the various digital product later stage.Existing filter, has two kinds of circular filter and square filters in appearance forrns.
Circular filter: its lens shape is circular, eyeglass packs into after picture frame, picture frame uses after utilizing standard thread to lock camera lens, or with other filter by the screw-threaded coupling use that superposes, wherein circular polarization filter is a kind of filter (below circular polarization filter is called for short polariscope) of commonly using, be divided into circular polarizer and linear polarizer by polarization mode, as shown in Fig. 1 a and 1b, in circular polarization mirror 4, circular polarization eyeglass 3 packs front picture frame 1 into, front picture frame 1 buckles into rear mirror frame 2, rear mirror frame 2 utilizes bottom standard thread to lock on camera lens or other filter, drive circular polarization eyeglass 3 by rotating front picture frame 1, reach the effect of adjusting polarization angle.
Square filter: in circular filter stack use procedure, the interval of eyeglass and eyeglass is larger, after stack, makes the minimizing of lens shooting visual angle, even makes image occur black angle, and screw-threaded coupling mode to change filter not convenient.In addition, the circular filter that the camera lens of different bores uses can not share, so a lot of photographer understands the square filter system that choice for use size is larger.As shown in Figure 2, the camera lens joint chair 6 of square filter support links with camera lens by screw thread or other locking modes, square filter inserts in square filter slot component 5 and uses, filter support, by conventionally having multiple draw-in grooves, facilitates square filter to carry out facility replacing and multi-disc filter stack use.
In photographer's shooting process, conventionally have polariscope and square filter, but traditional filter support is while using at the same time polariscope and square filter and inconvenient, existing assembling mode has two kinds:
As shown in Figure 2, show the three-dimensional exploded view under a kind of square filter support use state of the prior art.Wherein, polariscope 4 is arranged on camera lens joint chair 6 by rear mirror frame 2 bottom thread, and bottom and the camera lens of camera lens joint chair 6 join, and top and square filter slot component 5 join.Polariscope 4 is directly contained on camera lens joint chair 6, polariscope 4 uses between camera lens and square filter, lateral opening by camera lens joint chair 6 is adjusted polariscopic front picture frame 1, regulate narrow space, cannot adjust polarization angle by the front picture frame 1 of convenient rotation, the easy light leak of the opening part for regulating between polariscope and camera lens joint chair 6, impacts imaging picture simultaneously.
As shown in Figure 3, show another kind of square filter support in prior art and use state three-dimensional exploded view.Wherein, bottom and the camera lens of camera lens joint chair 6 join, and square filter slot component 5 is arranged on camera lens joint chair 6, and oversize polariscope 4 is by special screw thread joint chair 7, and oversize polariscope used is because size is larger, expensive.
