.Canon has released licenses for 5 brand-new lenses in Asia. The patents were 1st submitted to the Japanese License Office in January 2023 and formally posted today.
Wide-angle zooms.
Two of Canon's freshly posted patents are actually of what are actually described as sleek wide-angle zoom lens. The lens cover the zoom series of 15-28 mm and 17-30 mm. Both lenses also have a constant wide maximum eye of f/2.8. Canon already creates 14-35 mm f/4 is actually and 15-35 mm f/2.8 is actually lens in its own L-Series along with similar central length assortments. Given Canon's use of the condition "sleek" to define these lens, maybe that the licenses are going to provide smaller sized or even lighter lenses.

Telephoto zooms.
Canon's 3 various other brand-new patents all associate with telephoto zoom lenses. The patents cover lenses with the central length ranges of 70-300 mm, 300-600 mm as well as 400-600 mm. Just like the wide-angle zoom licenses, the telephoto zoom lenses are actually made to have a compact design. The 70-300 mm lense has a constant optimum aperture of f/4.

Lense mounts.
The patents deal with the optical layout of the lens and also do not suggest the lens mount. Nonetheless, the absolute most probably alternative will be actually Canon's radio frequency install. On top of that, Kengo Iezuka, who supervises preparation lenses at Canon, provided a meeting about RF lenses just recently. Throughout the job interview, Iezuka pointed out, "There are still several lenses that have not been launched to the globe. I can not talk about the specifics, but there are actually lens along with essential specifications, and lens with requirements that have never been actually observed before which no one can easily picture however.".
What our experts assume.
Until just recently, Canon has avoided various other producers coming from making radio frequency mount lenses. Now the firm is beginning to open up the market to various other lense producers, Canon needs to have to always keep innovating. The brand-new licenses reveal that Analects is actually working hard to build impressive brand new lenses for its RF mount cameras. Having said that, as regularly, where licenses are regarded, it is actually additionally significant to remember that the procedure is actually carried out primarily to defend technological growth. The enrollment of a patent does not consistently result in a product coming to market.
