.Canon has published patents for five brand-new lens in Japan. The licenses were 1st submitted to the Japanese License Office in January 2023 and also formally published this week.
Wide-angle zooms.
Two of Canon's recently posted patents are for what are actually described as sleek wide-angle zoom lens. The lenses cover the zoom ranges of 15-28 mm and also 17-30 mm. Both lens likewise possess a constant large max eye of f/2.8. Canon presently creates 14-35 mm f/4 is actually and also 15-35 mm f/2.8 IS lenses in its L-Series with similar focal duration varieties. Given Canon's use of the condition "portable" to illustrate these lens, it could be that the patents will certainly deliver smaller or lighter lens.

Telephoto zooms.
Canon's 3 other brand-new patents all relate to telephoto zoom lenses. The patents cover lens along with the focal size ranges of 70-300 mm, 300-600 mm and 400-600 mm. Just like the wide-angle zoom licenses, the telephoto zoom lens are actually designed to have a portable layout. The 70-300 mm lense possesses a continuous maximum eye of f/4. However, the various other two lens are actually shown as possessing variable f/2.8 -4.5 maximum apertures.

Lens installs.
The licenses deal with the optical design of the lens and do not signify the lens install. However, the absolute most very likely possibility would be Canon's radio frequency mount. On top of that, Kengo Iezuka, who supervises preparing lenses at Canon, gave an interview concerning RF lenses recently. Throughout the interview, Iezuka mentioned, "There are still lots of lens that have actually certainly not been actually launched to the globe. I can't talk about the specifics, but there are actually lens along with general standards, as well as lenses with standards that have actually never ever been found before and that nobody can easily visualize yet.".
What we assume.
Up until just recently, Canon has prevented various other manufacturers from creating RF position lenses. Now the company is beginning to open the marketplace to other lens producers, Canon needs to keep introducing. The new licenses present that Canon is working hard to cultivate stimulating brand new lens for its radio frequency position cameras. Nevertheless, as consistently, where patents are actually worried, it's likewise necessary to consider that the procedure is actually performed predominantly to shield technological growth. The registration of a patent doesn't constantly cause an item relating to market.
