Referring to fig. 1, a full-frame optical system according to an embodiment of the first aspect of the present invention includes, in order from an object side to an image side: the zoom lens comprises a first fixed lens group with positive focal power, a first focusing lens group with negative focal power, a second fixed lens group with positive focal power and a third fixed lens group with positive focal power.
The first fixed lens group includes a first negative meniscus lens 11, at least two first positive biconvex lenses (first positive lens 12, first positive lens 15, and first positive lens 16 are taken as examples in the figure), and first cemented doublet lenses 13 and 14 with positive focal power, wherein one side of the negative meniscus lens 11 facing the object side is a convex surface; the angle of the light of the off-axis field of view is reduced after passing through the first negative meniscus lens 11 of the first fixed lens group, so that the coma, curvature of field and distortion related to the field of view of the rear group are slightly reduced, but after the first negative meniscus lens 11 and the rear group are separated by a certain distance, the light caliber is increased more, so that more spherical aberration is generated, the aperture of the converged light can be reduced by the positive lens 12, the positive lens 15 and the positive lens 16, so that the spherical aberration is reduced, meanwhile, the dispersion coefficient difference of the positive and negative lenses of the double cemented lenses 13 and 14 is larger, and the chromatic aberration can be effectively reduced.
The first focusing lens group comprises at least one biconcave type second negative lens 21 and second double cemented lenses 22 and 23 with positive focal power, and the chromatic dispersion coefficients of the positive and negative lenses of the second double cemented lenses 22 and 23 have larger difference, which is beneficial to reducing chromatic aberration. The focal power of the whole first focusing lens group is negative, so that the equivalent focal length of the whole system can be effectively changed in the whole focusing process, and the imaging quality of different object distances is improved.
The second fixed lens group comprises third double cemented lenses 31 and 32 with negative focal power and at least one second positive lens 33; the second fixed lens group is a group with positive combined focal power, and the aperture of the light rays becomes larger after the light rays are diverged by the front group, so that the reduction of the spherical aberration becomes a key point, and the positive lens 32 and the third positive lens 33 of the double-cemented lens can share the reduction of the spherical aberration; in addition, the negative doublet lenses 31, 32 can effectively reduce the on-axis chromatic aberration because the second fixed lens group is located close to the stop STO.
The second focusing lens group comprises a third positive lens 41 and fourth double cemented lenses 42 and 43 with positive focal power; the third fixed lens group includes at least one third negative lens 51.
It can be seen that the lens group of the system adopts a structural form of 'two-group focusing and three-group fixing' to reasonably match and combine the focal power and the shape of each optical lens, so as to realize clear focusing from infinite object distance to-1 multiplied by close object distance in the whole range, the nearest focusing distance is 280mm, the whole-process distortion is less than 2%, and the relative illumination is more than 40%.
In some embodiments of the present invention, the third negative lens 51 included in the third fixed lens group is a meniscus lens or a biconcave lens curved toward the image plane, which is illustrated as a meniscus lens curved toward the image plane.
In some embodiments of the present invention, the third fixed lens group further includes a fourth positive lens 52 of a biconvex type or a fifth cemented doublet as shown in fig. 1 and 6, respectively, wherein the fifth cemented doublet is formed by cementing the fourth positive lens 52 and the fourth negative lens 53.
In some embodiments of the present invention, the focal length F1 of the first fixed lens group and the focal length F of the full-frame optical system satisfy the following relationship:
0.45≤F1/F≤0.61；
the focal length F2 of the first focusing lens group and the focal length F of the full-frame optical system satisfy the following relation:
-0.64≤F2/F≤-0.45；
the focal length F3 of the second fixed lens group and the focal length F of the full-frame optical system satisfy the following relation:
1.04≤F3/F≤1.6；
the focal length F4 of the second focusing lens group and the focal length F of the full-frame optical system satisfy the following relation:
0.91≤F4/F≤2.54；
the focal length F5 of the third fixed lens group and the focal length F of the full-frame optical system satisfy the following relation:
-1.52≤F5/F≤-1.24；
the focal length F and the total optical length L of the full-frame optical system satisfy the following relational expression:
0.28≤F/L≤0.39。
the lens with larger focal power generally has larger contribution to aberration, and the balance of each aberration is facilitated by reasonably matching the focal power.
In some embodiments of the present invention, an aperture stop STO is disposed between the first focusing lens group and the second fixed lens group, and the aperture stop is used to limit the aperture of the light beam.
