.Canon has actually released patents for 5 new lens in Asia. The patents were initial accepted the Oriental Patent Workplace in January 2023 and also officially published today.
Wide-angle zooms.
Two of Canon's freshly posted patents are for what are actually described as sleek wide-angle zoom lens. The lens deal with the zoom ranges of 15-28 mm and 17-30 mm. Both lenses likewise have a continuous broad maximum eye of f/2.8. Canon currently creates 14-35 mm f/4 IS and 15-35 mm f/2.8 IS lenses in its L-Series with identical central length variations. Given Canon's use the term "small" to define these lenses, perhaps that the licenses will certainly give smaller sized or lighter lenses.

Telephoto zooms.
Canon's three various other brand-new patents all relate to telephoto zoom lenses. The patents cover lenses with the focal duration ranges of 70-300 mm, 300-600 mm as well as 400-600 mm. Just like the wide-angle zoom patents, the telephoto zoom lenses are actually developed to possess a sleek design. The 70-300 mm lense has a constant maximum aperture of f/4. Nonetheless, the various other 2 lens are shown as having variable f/2.8 -4.5 max apertures.

Lense mounts.
The patents cover the visual design of the lenses and also don't signify the lense mount. Nevertheless, one of the most likely alternative will be actually Canon's radio frequency mount. Furthermore, Kengo Iezuka, who supervises planning lens at Canon, gave a meeting concerning radio frequency lenses lately. During the course of the job interview, Iezuka mentioned, "There are actually still lots of lenses that have actually not been actually launched to the globe. I can't talk about the specifics, yet there are actually lens along with general standards, and lenses along with standards that have never been actually found prior to and also no one may imagine however.".
What we assume.
Until just recently, Canon has prevented other suppliers from bring in RF place lens. Right now the company is beginning to open the market place to other lense manufacturers, Canon needs to have to maintain innovating. The brand-new patents show that Canon is working hard to establish interesting brand-new lens for its own radio frequency position video cameras. Nevertheless, as constantly, where patents are actually involved, it's also important to bear in mind that the procedure is actually done largely to defend technological growth. The enrollment of a patent doesn't consistently lead to an item involving market.
