Description
Technical field
The present invention relates to a kind of video and the technology in film shooting field, it is specifically a kind of in interchangeable of dolly-out,ing dolly-back it is fixed
Zoom lens.
Background technique
Cinema scene is exactly film shooting camera lens.Cinema scene not only possesses most top optics quality, but also 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, and there are no a companys to release film truly at home so far
Camera lens for shooting.Existing camera lens have the disadvantage that 1) resolution ratio is not high: the resolution ratio of film camera has been at present
It can achieve 6K or 8K, 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 camera lens are harsh not as good as cinema scene to the control at dark angle, because
This dark angle is obvious, is unable to satisfy video and film shooting uses；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
It video camera subjectivity visual angle can be more serious when mobile；If the appearance within sweep of the eye of theater viewers too significantly distorts,
Then it is possible that causing to move vertigo；So the image field of cinema scene must be as straight as possible；And often due to camera lens
It is inadequate to the control of distortion, so being unable to satisfy cinema scene to the high request of distortion；4) cell breath is obvious: camera lens carries out pair
Cell breath can be generated in burnt process, cell breath changes it in addition to the composition that can not almost discover for camera lens
Outside, picture is not influenced by cell breath；And it carries out chasing after coke for film making, in picture or be moved between different subjects
Burnt gimmick is very common, so very high to the requirement for inhibiting cell breath, general camera lens are unable to satisfy requirement.
Summary of the invention
The present invention In view of the above shortcomings of the prior art, proposes interchangeable tight shot of dolly-out,ing dolly-back in one kind, uses
Group, which floats, afterwards focuses, and can meet the 8K resolution camera of matching silent frame and super35 picture, without obvious dark angle, distorts
It is minimum, cell breath is faint, cost performance is high.
The present invention is achieved by the following technical solutions:
The present invention includes: the first eyeglass group and the second eyeglass group being arranged successively from the object side to image side, in which: works as subject
When body is mobile to short distance from infinity, the first eyeglass group is fixed, and the second eyeglass group gathers from image side to the movement of object side
It is burnt.
The first eyeglass group is cemented doublet with positive light coke or by with positive light coke and negative power
Two independent eyeglass compositions.
The second eyeglass group includes: the second eyeglass being arranged successively, third eyeglass, the 4th eyeglass, diaphragm, the 5th mirror
Piece and the 6th eyeglass, in which: the second eyeglass, third 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.
The first eyeglass group and the second eyeglass group preferably satisfies: 2.5 < FG1/FG2< 3.5, in which: 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 eyeglass group and the second eyeglass group composition preferably satisfies: 0.3 < BFL/EFL < 0.7, in which:
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 relationship of back focal length,
So that the focal length of camera lens and rear burnt ratio are in a suitable range and reach the resolution ratio of 8k.
The first eyeglass group preferably satisfies: 2 < FG1/ F < 12, in which: FG1For the focal length of the camera lens the first eyeglass group, F
For the camera lens whole focal length, be conducive to the tune of assembly and overall weight and center of gravity while camera lens is miniaturised
It is whole.
5th eyeglass preferably satisfies: 0.2 < | ND51-ND52| < 0.5, in which: ND51For the 5th with positive light coke
Refractive index of the eyeglass close to object space side mirror piece, ND52It is the 5th eyeglass with positive light coke close to the refractive index of image side eyeglass,
5th eyeglass can aid in the axial chromatic aberration and ratio chromatism, of correction camera lens, while compensate the spherical surface that the first eyeglass group is formed
Aberration, and eliminate the ghost of camera lens.
6th eyeglass is aspherical lens, and the 6th eyeglass preferably satisfies: ND6> 1.75, in which: ND6It is the 6th
Refractive index of the eyeglass relative to d line (λ=587.5600nm).
Technical effect
To solve the problems, such as that existing camera lens resolution ratio is inadequate, the present invention joined Glass aspheric mirror in camera lens
Piece has been obviously improved resolving power and resolution ratio, enables 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 light ratio makes to present on picture more by the light of entire camera lens also 35% or more
Uniformly, be conducive to Correct exposure when film shooting.
To solve the problems, such as that it is big that existing camera lens distort, present invention optimizes the structure of camera lens and optical paths, particularly plus
The strong symmetry of camera lens rear end group, so that distortion is minimum, optical distortion is 1% hereinafter, ensure that picture from center to most
Deforming and being distorted will not occur in periphery.
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 from infinity to when short distance variation, pre-group is fixed, and rear group is focused from image space to object space movement.And
Especially optimization diaphragm has accomplished that camera lens from when infinitely focusing as far as minimum distance, is drawn to optimal location at a distance from the eyeglass of front and back
Face visual field changes within 3%, effectively to weaken cell breath.
Compared with prior art, the present invention is floated using rear group and is focused, and optimizes diaphragm at a distance from the eyeglass of front and back, effectively
Weaken cell breath, the image for taking in camera lens is without obvious dark angle, and distorting, minimum, cell breath is faint, can meet and match complete draw
The 8K resolution camera of width and super35 picture, low in cost, cost performance is high.
