It looks like Canon is going to expand its V lineup of lenses with multiple motorized zoom patents found covering:
- 20-50mm f/4 Full Frame
- 20-60mm f/4 Full Frame
- 18-45mm f/4 Full Frame
- 16-35mm f/4 Full Frame
- 17-45mm f/2.8 APS-C
- 16-45mm f/2.8 APS-C
- 17-75mm f/2.8-4.4 APS-C
- 17-45mm f/2.8 Super35mm
- 24-50mm f/4 Full Frame
- 25-60mm f/4 Full Frame
- 20-40mm f/2.8-3.2 Full Frame
The range of lenses starts quite wide, so they might be used for selfies, etc… We also have some of the patents in detail here. You can find more details at mirrorless-camera.info
The Full Frame Canon100-500mm F4.5-6.3 IS and Canon 100-600mm F4.5-6.3 IS patent can be found below:
overview
- [Publication number] P2025091080

Zoom lenses used in imaging include so-called positive-lead zoom lenses, which have a lens group with positive refractive power located closest to the object and meet the requirements of being small, lightweight, and having little fluctuation in optical performance during focusing. In addition, a floating system is used in which multiple lens groups are moved during focusing. - [0003]
Patent document 1 discloses a zoom lens having a first lens group with positive refractive power arranged closest to the object, in which the spacing between adjacent lens groups changes during zooming, and multiple lens groups are moved during focusing. - [0005]
In general, in order to make a zoom lens compact, it is effective to adopt a telephoto type power arrangement at the telephoto end and to strengthen the positive refractive power on the object side and the negative refractive power on the image side. However, if the refractive power of each lens group is strengthened, the fluctuation of various aberrations accompanying zooming becomes large, and it becomes difficult to satisfactorily correct various aberrations with a small number of lenses. Also, in a positive lead type zoom lens, the effective diameter of the lens group on the object side is large, so the configuration of the lens group on the object side to reduce weight is important. - [0006]
Furthermore, in a telephoto zoom lens, the amount of movement of the focus lens group during focusing tends to be large, so the arrangement of the focus lens group is important in order to suppress fluctuations in optical performance during focusing. - The present
invention provides a zoom lens which is small and lightweight and has little fluctuation in optical performance during focusing. - [0014]
In each cross-sectional view, Li represents the i-th lens group counted from the object side among the lens groups included in the zoom lens L0. LR is a rear group including all lens groups arranged on the image side of the third lens group L3. LIS is an anti-vibration group having a function (anti-vibration function) of correcting image blur caused by camera shake or the like by moving in a direction including a directional component perpendicular to the optical axis. The anti-vibration group may be an entire lens group or a subgroup that is a part of the lens group. The subgroup is a group of one or more lenses whose structural length (the distance from the surface closest to the object side to the surface closest to the image side of the subgroup) remains unchanged during zooming.
