How to download zoom old version
Please advise. Hi XB70 Unfortunately, there is no report or tracking of which versions you have installed on your computer. If you would like to look at the list of previous windows versions and choose a specific version you'd like to rollback to, I can provide the download link for that specific version. Thanks for the offer. I have "upgraded" to version 5. If it is back to normal with 5. If however, having Zoom loaded continues to result in browser pages not loading--"not enough resources," Zoom meeting sound being totally garbled unless having the meeting page front and center--previously I could listen even if the meeting was minimized, and other problems when 5.
Thank you. Hi My My image is frozen all the time in the calls with the current version of Zoom. The computer resources are only for Zoom. Could I get a link for a version from the beginning of Jan? Sorry for the delay. Here is the link for 5. Sure thing! Here is 5. December 27, version 5.
Do you happen to have the 5. If so, do you mind sharing please. Zoom desktop client 5. Hi Bort, do you happen to have Mac M1 version for build 5. Thank you very much!
FYI the reason I needed this version was that in 5. A zoom lens system of the present invention consists of four lens groups in which a fourth lens group does not move during a zooming operation. The magnification varying operation is mainly carried out by a movement of a negative second lens group. Figure 13 shows zooming tracks of each of the lens groups elements 11, 12, 13 and 14 of the zoom lens system.
Generally, to increase the zoom ratio in a zoom lens system as constructed above, it is necessary to increase the distance between the second lens group and the third lens group at the shortest focal length extremity, as specified in relationship 1 above. If the ratio defined in relationship 1 is below the lower limit, it is difficult to obtain a high zoom ratio. If an attempt is made to increase the zoom ratio when the ratio defined in relationship 1 is below the lower limit, considerable fluctuation of aberrations produced during the zooming operation would occur.
Conversely, if the ratio defined in relationship 1 is above the upper limit, no miniaturization of the zoom lens system can be achieved. Moreover, since the magnification is varied mainly by the movement of the second lens group as mentioned above, the lateral magnification of the second lens group at the shortest focal length extremity is set to be small, as specified in relationship 2 above, in comparison with a conventional zoom lens having a relatively small zoom ratio.
If the lateral magnification of the second lens group specified in relationship 2 is smaller than the lower limit, it is impossible to obtain a high zoom ratio without increasing the displacement of the second lens group. The increase in the displacement of the second lens group leads to an increase in the size of the zoom lens system.
Conversely, if the lateral magnification of the second lens group is above the upper limit specified in relationship 2 , the lateral magnification met is too large to correct the fluctuation of the aberrations caused during the zooming operation, since the lateral magnification m2 T at the longest focal length extremity is substantially identical to a product of the lateral magnification m2w at the shortest focal length extremity and the zoom ratio i.
Relationship 3 above specifies the lateral magnification of the fourth lens group having an image forming function. To increase the aperture so that the F-number can be approximately equal to 1. If the lateral magnification of the fourth lens group is larger than the upper limit specified in relationship 3 , it is difficult to correct the aberrations caused in the variable power lens groups first through third lens groups by the fourth lens group.
Thus, it is difficult to obtain a zoom lens system having an aperture which is large and with an F-number approximately l. If the lateral magnification of the fourth lens group is smaller than the lower limit specified in relationship 3 , the negative power of the variable power lens groups is reduced, that is, the focal length of the variable power lens groups is increased, and hence it is necessary to increase the whole length of the variable power lens groups to obtain a desired focal length range.
The fourth lens group consists of a first sub-lens group and a second sub-lens group in this order from an object side. Relationship 4 above specifies the lateral magnification of the second sub-lens group of the fourth lens group, to reduce the whole length of the fourth lens group and to balance the correction of the aberrations by the fourth lens group.
If the lateral magnification of the second sub-lens group is above the upper limit specified in relationship 4 , the lens system can be miniaturized, but the power of the first sub-lens group is increased, and hence, it is difficult to effectively correct the aberrations particularly, spherical aberrations of a zoom lens having a small F-number approximately equal to 1.
If the lateral magnification of the second sub-lens group of the fourth lens group is below the lower limit specified in relationship 4 , the aberrations can be effectively corrected, but the whole length of the fourth lens group is increased contrary to the desire for miniaturization.
The first sub-lens group preferably consists of a positive first lens element, a positive second lens element, a negative third lens element, and a positive fourth lens element, in this order from the object side. The second sub-lens group preferably consists of a positive first lens element, a negative second lens element, and a positive third lens element, in this order from the object side.
As mentioned above, if the negative lens element respectively provided in the first sub-lens group and the second sub-lens group is provided having positive lens elements at a front i. Relationships 5 , 6 and 7 above specify the requirements of the lens elements of the first sub-lens group consisting of a positive first lens element, a positive second lens element, a negative third lens element and a positive fourth lens element.
Relationship 5 defines the power of the first sub-lens group belonging to the fourth lens group. If the value of the ratio defined in relationship 5 is larger than the upper limit, the lens system can be made compact but it is difficult to correct the spherical aberrations and to obtain a large aperture. If the value is smaller than the lower limit specified in relationship 5 , the whole length of the fourth lens group is increased.
Relationship 6 defines the power of the negative lens element of the first sub-lens group. If the value of the ratio defined in relationship 6 is larger than the upper limit, the negative power is too small to correct the aberrations within the first sub-lens group having a large positive power. If the value is smaller than the lower limit specified in relationship 6 , the negative power is so large that a high-order spherical aberration is produced.
Relationship 7 specifies the power of the lens element of the first sub-lens group that is located closest to an image to be formed to correct the aberrations produced by the negative lens element of the first sub-lens group. If the value of the ratio specified in relationship 7 is above the upper limit, the lens system can be appropriately miniaturized, but the power of the lens element of the first sub-lens group that is located on the image side and the power of the negative lens element thereof, tend to become so large that high-order spherical aberrations are produced.
If the value of the ratio specified in relationship 7 is below the lower limit, no correction of aberrations can be effected within the first sub-lens group. Relationships 8 , 9 and 10 above specify the requirements of the second sub-lens group consisting of a positive first lens element, a negative second lens element and a positive third lens element. Relationship 8 defines a ratio between the powers of the first sub-lens group and the second sub-lens group.
Preferably, the power of the second sub-lens group is smaller than the power of the first sub-lens group to miniaturize the lens system and effectively correct the aberrations. All rights reserved.
