– Overseas price: 2099 British Pound Sterling, 2399 Euros
The FE 24-70mm F2.8 GM II, which is rumored to be announced today at 23:00 JST, leaked image, spec, and price information. The source of the information is a thread related to E-mount lenses on a huge bulletin board, and it seems that the person who posted the image is the usual person.
Although the total length is not known from the specifications, it weighs 695 g, which seems to be considerably lighter than the current model. Also, the shortest shooting distance is considerably shorter. It seems that the lens barrel is equipped with an aperture ring, which was confirmed in the previous leak image.
The latest patent reveals Canon working on an ultrawide range of RF Mount lenses. Japanese website spotted all the three lens patents that Canon is currently working on.

of Invention: Zoom Lens and Imaging Device
PROBLEM TO BE SOLVED: To suppress aberration fluctuation at the time of magnification change in a small and wide-angle zoom lens.
As a wide-angle zoom lens, Patent Document 1 and Patent Document 2 disclose a zoom lens that moves the first lens group on the most object side to perform scaling.
However, in the zoom lenses disclosed in Patent Documents 1 and 2, the length of the back focus increases the diameter of the first lens group, and the weight of the first lens group to be moved at the time of scaling increases. Moreover, since a wide-angle lens uses a plurality of large-diameter lenses to widen the angle and correct distortion, the weight of the first lens group tends to increase. As a result, it becomes difficult to suppress an increase in aberration due to eccentricity during the movement of the first lens group.
In the present invention, there is provided a compact zoom lens capable of suppressing aberration fluctuations at the time of scaling while having a wide angle.

As usual, we know that a patent takes at least 2 years of time to become a real product. And at the same time, all the patents do not always get’s approved. So, here we are not so sure which of the three lenses will arrive as a real product in the market.
According to the latest rumors, surfaced over the web Tamron 17-28mm Di III VXD G2 Lens will arrive at the end of 2022. The lens will offer significantly improved optical and autofocus performance and new function customization.
The new 17-28 mm F2.8 G2 incorporates a new optical construction to enhance imaging performance and is compatible with the latest model digital cameras like Sony A7 IV with higher resolution sensors. The AF drive, TAMRON’s VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism, is adopted to deliver higher autofocus speed with greater precision
According to the latest rumors that surfaced over the web, Now we have confirmation that Canon’s upcoming APS-C flagship camera name will be called Canon R7. So, finally, have confirmation the Canon 7D Mark II Mirrorless successor will be called the Canon R7.
Now, another part of the rumor suggests the camera will arrive sometime in Q4 of 2022. Possibly in August or September 2022.
