Tamron 35mm F1.8 VC, 50mm F2.5 VC, 80mm F2.8 VC, and 100mm F2.8 VC Patents Found

By Louis Ferreira | Published: August 12, 2022

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.

Focal length 49.9833 48.4311 45.6545 43.5921
F number 2.6093 2.6122 2.6766 2.7802

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.

Tamron Has A Lot Of Momentum

By Louis Ferreira | Published: August 9, 2022

Tamron has been doing better than most since they are manufacturing mirrorless lenses for most mounts now. In their financial results, Tamron expects to launch 5 lenses this year, and we already know about two of them (Tamron 50-400mm F/4.5-6.3 Di III VC VXD and Tamron 17-70mm f/2.8 Di III-A VC RXD for X-mount), so there are still 3 more to come.

More 2nd quarter FY2022 financial result points:

Net sales increased by more than 15%,
Operating income increased by more than 1.5 times (significant increase in operating income by about 40% YoY)
Gross margin increased by about 2 percentage points,
Operating income, ordinary income, and net income reached historic high
Increase of net sales excluding impact of exchange rate: Photographic Products +1,390 million JPY

Forecast:

Sales of own-brand products is expected to increase by double-digits, and sale of OEM products will remain flat.
Operating income on net sales is expected to increase further due to the improvement of the gross profit margin, and operating income is expected to increase by double-digits.

“Aiming to set record-high profits with a double-digit increase in net sales and increase in operating income by more than 1.3 times compared to the same period of the previous year. We are aiming to set a record high in operating income, ordinary income, and net income: operating income and ordinary income are to be the first time in 15 years since 2007, net income is to be the first time in 3 years since 2019.”
