Some new patents were found for Tamron VC lenses, and this could be a new line of lenses designed for vlogging cameras like the ZV-E10. These lenses seem to be designed to minimize focus on breathing and shake, but the focal lengths of 35mm F1.8 VC, 50mm F2.5 VC, 80mm F2.8 VC, and 100mm F2.8 VC aren’t ideal for vlogging. Maybe an E-mount Video Camera.
Example 1 (50mm F2.5 VC)
Focal length 49.9833 48.4311 45.6545 43.5921
F number 2.6093 2.6122 2.6766 2.7802
Half angle of view 23.1943 23.1920 23.0731 22.8720
Example 2 (80mm F2.8 VC)
Focal length 78.8596 76.4902 72.2186 69.1983
F number 2.8545 2.8742 2.9429 3.0388
Half angle of view 15.1336 14.9873 14.5638 14.1307
Example 3 (100mm F2.8 VC)
Focal length 104.9887 100.3831 92.5082 89.5415
F number 2.8961 2.9117 3.0806 3.1799

of invention: Optical system and imaging device - An object of the present invention is to provide a lightweight, compact, and high-resolution optical system and an imaging device having the optical system.
- If the change in image magnification due to the movement of the focus lens is large, the image will always appear to sway, which is very unnatural. Therefore, it is one of the important items to keep the change in magnification during wobbling small for a lens compatible with moving images.
- When shooting moving images, it is often necessary to change the direction of the camera or move the photographer in accordance with the movement of the subject, so image blurring is likely to occur. For this reason, it is preferable that an imaging lens for moving image shooting is provided with a vibration reduction lens group responsible for vibration reduction correction.
- SUMMARY OF THE INVENTION It is an object of the present invention to provide a lightweight, compact, and high-resolution optical system and an imaging device having the same.
