Description
Technical field
The present invention relates to a kind of video and the technology in film shooting field, interchangeable of specifically being dolly-out,ed dolly-back in one kind is determined
Zoom lens.
Background technology
Cinema scene is exactly film shooting camera lens.Cinema scene not only possesses most top optics quality, and its machine
The design of tool structure has also fully taken into account the professional needs of film making, thus its is professional very strong.But due to movie mirror
The design difficulty and manufacture difficulty of head are very high, do not have also a company to release film truly at home so far
Camera lens for shooting.Existing camera lens have the following disadvantages：1) resolution ratio is not high：The resolution ratio of film camera has been at present
6K or 8K can be reached, but almost all of camera lens resolving power is not high on the market, can not match high-resolution
Video camera uses；2) there is obvious dark angle：Limitation and camera lens plating film water due to physical law (mainly reflection and the law of refraction)
Flat limitation, all camera lenses more or less can all have dark angle；And control of the camera lens to dark angle is harsh not as cinema scene, because
This dark angle is obvious, can not meet that video and film shooting use；3) distortion is big：The picture of dynamic image distorts often than quiet
State photo seems to become apparent from, and pincushion or barrel distortion will once show shape at once when dynamic element occurs in picture, and
Video camera subjectivity visual angle can be more serious when movement；If the appearance within sweep of the eye of theater viewers too significantly distorts,
Then it is possible that cause to move vertigo；So the image field of cinema scene must be as straight as possible；And due to camera lens often
Control to distortion is inadequate, so can not meet high request of the cinema scene to distortion；4) cell breath is obvious：Camera lens is carried out pair
Cell breath can be produced in burnt process, cell breath changes it except the composition that can not almost discover for camera lens
Outside, picture is not influenceed by cell breath；And carry out chasing after Jiao for film making, in picture or moved between different subjects
Burnt gimmick is very common, so very high to the requirement for suppressing cell breath, general camera lens can not meet to require.
The content of the invention
The present invention is directed to deficiencies of the prior art, proposes interchangeable tight shot of being dolly-out,ed dolly-back in one kind, uses
Group, which floats, afterwards focuses, and can meet the 8K resolution cameras for matching silent frame and super35 pictures, without obvious dark angle, distorts
It is minimum, cell breath is faint, cost-effective.
The present invention is achieved by the following technical solutions：
The present invention includes：The the first eyeglass group and the second eyeglass group being arranged in order from the object side to image side, wherein：Work as subject
For body from infinity to when closely moving, the first eyeglass group is fixed, and the second eyeglass group moves from image side to thing side to be gathered
It is burnt.
The first described eyeglass group is for the cemented doublet with positive light coke or by with positive light coke and negative power
Two independent eyeglass compositions.
The second described eyeglass group includes：The second eyeglass, the 3rd eyeglass, the 4th eyeglass, diaphragm, the 5th mirror being arranged in order
Piece and the 6th eyeglass, wherein：Second eyeglass, the 3rd eyeglass and the 6th eyeglass have positive light coke, and the 4th eyeglass has negative light focus
Degree, the 5th eyeglass have positive light coke, and the 5th eyeglass is cemented doublet.
Described the first eyeglass group and the second eyeglass group preferably meets：2.5<FG1/FG2<3.5, wherein：FG1For the first eyeglass
The whole focal length of group, FG2For the whole focal length of the second eyeglass group.
The camera lens of the first described eyeglass group and the second eyeglass group composition preferably meets：0.3<BFL/EFL<0.7, wherein：
BFL is the optic back focal of camera lens, and EFL is the whole focal length of camera lens, by limiting the whole focal length of camera lens and the relation of back focal length,
So that the focal length of camera lens and rear burnt ratio are in a suitable scope and reach 8k resolution ratio.
The first described eyeglass group preferably meets：2<FG1/F<12, wherein：FG1For the focal length of the camera lens the first eyeglass group, F
For the camera lens whole focal length so that camera lens is advantageous to the tune of assembling and overall weight and center of gravity while can further minimizing
It is whole.
The 5th described eyeglass preferably meets：0.2<|ND51-ND52|<0.5, wherein：ND51For the 5th with positive light coke
Eyeglass is close to the refractive index of object space side mirror piece, ND52Refractive index for the 5th eyeglass with positive light coke close to image side eyeglass,
5th eyeglass can aid in the axial chromatic aberration and ratio chromatism, of correction camera lens, while compensate the sphere that the first eyeglass group is formed
Aberration, and eliminate the ghost of camera lens.
The 6th described eyeglass is aspherical lens, and the 6th eyeglass preferably meets：ND6>1.75 wherein：ND6For the 6th
Eyeglass relative to d lines (λ=587.5600nm) refractive index.
Technique effect
To solve the problems, such as that existing camera lens resolution ratio is inadequate, the present invention adds Glass aspheric mirror in camera lens
Piece, resolving power and resolution ratio are obviously improved, have enabled the invention to the professional 8K for meeting at present highest resolution on the market
The use of resolution camera.
To solve the problems, such as that existing camera lens have obvious dark angle, the present invention improves periphery light ratio in design.I.e.
Make when aperture standard-sized sheet, periphery is bright than also more than 35%, making to present on picture more by the light of whole camera lens
Uniformly, Correct exposure during film shooting is advantageous to.
To solve the problems, such as that existing camera lens distortion is big, present invention optimizes the structure of camera lens and light path, especially adds
The strong symmetry of camera lens rear end group so that distortion is minimum, and optical distortion ensure that picture from center to most below 1%
Periphery is also not in deformation and distortion.
To solve the problems, such as that existing camera lens cell breath is obvious, the present invention is floated using rear group by the way of focusing.
When shooting object is from infinity to when closely changing, pre-group is fixed, and rear group moves from image space to object space and is focused.And
Especially optimization diaphragm has accomplished that camera lens from when infinitely being focused on as far as minimum distance, is drawn with the distance of front and rear eyeglass to optimal location
Face visual field change is within 3%, effectively to weaken cell breath.
Compared with prior art, the present invention is floated using rear group and focused, the distance of optimization diaphragm and front and rear eyeglass, effectively
Weaken cell breath, making the image that camera lens is taken in, distortion is minimum, cell breath is faint, can meet to match full picture without obvious dark angle
The 8K resolution cameras of width and super35 pictures, cost is cheap, cost-effective.
