Abstract
An ultrathin structure of a filter ring is provided. A first ring member comprises a lantern ring and a first ring member wing edge, the basal part of the lantern ring extends to form the first ring member wing edge, and a second ring member is sleeved on the lantern ring in a clamping manner; a second ring member comprises a threaded connection ring and a second ring member wing edge, the basal part of the threaded connection ring extends to form the second ring member wing edge, the second ring member is sleeved on the lantern ring of the first ring member in a clamping manner through the threaded connection ring, and the filter ring is connected to a lens of a camera through an external thread of the threaded connection ring. A first lens is arranged in the first ring member, a second lens is arranged in a third ring member in clamp connection with the outer side of the first ring member, the filter ring is connected to the lens of the camera and separated from the lens of the camera in a rotating manner through the external thread of the threaded connection ring of the second ring member, after the filter ring is connected to the lens of the camera, the first ring member of the filter ring can at least rotate by 180 degrees relative to the lens of the camera, various functions of a filter can be achieved conveniently, and the thickness of the whole filter ring is reduced. When a short-focus ultra wide angle lens is used, the edge of the frame of the lens does not block incident light rays, and therefore "dark corners" do not appear in pictures, and the filter ring is very convenient.
Description
Technical field
The utility model belongs to the filter loop technique field of camera lens, specifically relates to a kind of superthin structure of filter ring.
Background technology
Photography filter, according to different functions, can be divided into: A, single structure, and single lens fixed installation, can not modulation; B, two-fold structure, single eyeglass modulation or two eyeglasses can subtend modulations; C, three stack structures, also modulation in the same way of two eyeglass subtends modulation, function the best of three stack structures, applies also extensive.The filter of three stack structures is formed by three single structure clampings, in actual applications, by the project organization of prior art, even the thickness of each single structure is down to bottom line, thickness after its assembling, still can cause following problem: in the time that camera uses 16mm wide-angle lens to take, the three stack structure filters that front end installs additional can stop that because picture frame edge is too high light incident produces picture " dark angle ", and the 16-35mm wide-angle zoom lens conventional camera lens that is a landscape photography, frequency of utilization is very high.Therefore, do not affecting under the prerequisite of three stack structure filter function integralities, designing a new structure that can effectively reduce filter ring thickness, solving multi-functional filter and in the time of wide-angle photography, occur " dark angle " drawback problem, seeming particularly necessary.
