Description
Technical field
The utility model relates to photographic goods technical fields, more particularly, to a kind of adjustable ultra-wide angle filter support.
Background technique
Filter is a kind of is mounted on before the equipment camera lens such as camera or video camera for filtering the auxiliary lens of natural light, simultaneously
It shields to camera lens.With the development of camera work, requirement of the people to camera work is higher and higher, therefore filter makes
With also more and more.With the continuous development of digital imaging technique, people make processing after having begun transmission more and more
Mode to increase filtering effects for the photo of oneself.However, still there is the effect as the filters such as the Graduated Filter mirror or ND dim light mirror
It is that shooting high quality special-effect is indispensable, post-production software system, which can not simulate, to be come.In photography, especially scene is taken the photograph
Shadow, in order to reach preferable effect of shadow, in order to change or improve the effect of image obtained by capture apparatus, it will usually in camera
Or filter is set before the camera lens of video camera, filter is to be mainly used for sunrise and at sunset before being mounted on camera lens by filter support
The adjustment big light of image than, shoot under strong light slow door and reduce camera shutter speed and can not be adjusted for the various digital product later periods
Photographic effects on.
Currently, camera filter is classified according to different functions, and it is many kinds of, shoot the commonly used master of special-effect
It include: dim light mirror, i.e., middle gray out, middle grey dim light mirror, also known as ND mirror, for weakening light intensity；Gradual change mirror is divided into middle ash
The Graduated Filter, for adjusting, sunrise, big light compares scene at sunset.Color gradients filter etc..
In face of such numerous filter types, be on the one hand cameraman when shooting picture with scenes often according to shooting picture
Different focal length section camera lens is selected, on the other hand various cameras are to meet different bores and different focal length section camera lens bayonet needs, special
It is not various camera bugeye lenses, will be equipped with different filter supports can reach photographing request, and bracket also needs to pacify
Assembly and disassembly are unloaded, and misoperation is also easy to that filter is caused to wear in the process, influence shooting quality, while being equipped with a variety of filter branch
Frame also needs to configure matched sizes filter piece, not only increased input cost but also it is not portable and use.
Summary of the invention
The purpose of the utility model is to overcome deficiencies in the prior art, provide a kind of structurally reasonable, design science
Adjustable ultra-wide angle filter support.
The adjustable ultra-wide angle filter support of the utility model, it is characterised in that the bracket includes rack body, camera lens
Hole, fixator, card slot, filter folder, through-hole and adjustment screw, rack body one end are provided with camera aperture, and fixator is arranged in mirror
In head bore, card slot is provided on the inner wall of rack body two sides, setting filter presss from both sides in card slot, and rack body bottom is provided with through-hole,
Lead to the hole site is corresponding with groove position, setting adjustment screw in through-hole.
The fixator includes semicircular rubber case, spring and fixed screw, and two semicircular rubber cases are opposite
A spring is fixed at setting, the both ends of rubber case respectively, and two rubber cases are connected as an entirety, two fixed spiral shells by spring
Silk is separately positioned at the top and bottom of camera aperture, and the top and bottom of the rubber case of two connections is contacted with fixed screw respectively.
When in use, by fixator by stent clamping on different bore camera lens, first by support casing in camera lens
On, it enables camera lens pass through rubber case and is compressed then according to different Lens caliber size rotary fixing screw silks by fixed screw
Spacing between rubber case enables two rubber cases be fastened on the position up and down of camera lens, when needing striking, by fixed screw
Unscrew, under spring force, rubber case struts, and can remove bracket.
It is one group that the filter, which presss from both sides two, and every group of filter sandwiched is set in two opposite card slots, and filter folder is one
Circular arc type elastic slice, when in filter disc insertion card slot, filter disc bottom squeeze filter folder enables filter folder shrink, meanwhile, in elastic slice itself
Resilient force under, two sides elastic slice to carriage center position squeeze, filter disc can be clamped, when needed, rotation can also be passed through
The adjustment screw turned in the through-hole of rack body bottom jacks up filter disc upwards, is finely adjusted to filter disc height.
In use, camera lens are first passed through camera aperture and are blocked with the rubber case on fixator by photographer, it, can when needing
It filter disc to be inserted into along bracket along card slot, and is fixed on filter folder, finely tunes filter disc height using adjustment screw, can be taken the photograph
Shadow creation.
The adjustable ultra-wide angle filter support of the utility model, structurally reasonable, design science increase by one on camera lens
Bracket can be adapted for the bugeye lens and all kinds of zoom lens of existing different size bores and model, filter disc be inserted into position
The gap set between camera lens increases, and rub camera lens when filter disc being avoided to be inserted into, while being consolidated using the fixator of spring connection
It is fixed, it is easy to disassemble, improve installation effectiveness.
