Some very attention-grabbing Canon lens patents have been printed in Japan, arriving just some weeks after a Canon government stated the corporate is growing new RF lenses “nobody can think about but.” It’s price including very important context earlier than trying on the 5 patents printed this week. As is all the time the case with patents, there isn’t a assure that any described merchandise will ever see the sunshine of day. Firms, together with Canon, continuously file new patents, and solely a few of the described gadgets and applied sciences are ever carried out in a real-world services or products. With that important caveat apart, what has Canon patented this time? As reported by Asobinet, the Japanese digital camera firm’s patents for 15-28mm f/2.8 and 17-30mm f/2.8 lenses have been granted by Japanese regulators. These patents had been submitted in January 2023 and formally printed at present, July 30. The documentation outlines a “compact, wide-angle zoom lens” with a quick, fixed f/2.8 aperture. A patent for a 17-30mm f/2.8 lens system | Canon In Canon’s RF system it already has RF 14-35mm f/4 L IS USM and RF 15-35mm f/2.8 L IS USM lenses, so presumably, the brand new patents relate to a possible wide-angle lens that mixes the compact and light-weight design of the RF 14-35mm f/4 with the pace of the RF 15-35mm f/2.8, albeit with barely much less vary than both of the prevailing lenses. A 15-28mm f/2.8 or 17-30mm f/2.8 could be all-new designs for Canon, however extra patents higher match Canon’s declare that it’s growing lenses no one has imagined but. Asobinet additionally detailed three extra new Canon patents, and they’re all for telephoto zoom lenses.
These patents had been filed simply in the future earlier than the wide-angle zoom patents detailed above and had been printed in Japan yesterday, July 29. They element a trio of designs for 70-300mm f/4, 300-600mm f/2.8-4.5, and 400-600mm f/2.8-4 lenses. Canon’s patent exhibits a 300-600mm f/2.8-4.5 lens | Canon Canon says there was elevated demand for telephoto zoom lenses that characteristic quick apertures and excessive optical efficiency but are small and compact. The patents depend on intelligent optical designs to keep up quick apertures in a comparatively small type issue. Whereas a 70-300mm f/4 lens is a novel concept, the 2 longer zoom lenses could show extra compelling to sports activities and wildlife photographers. Canon has proven its means to develop distinctive, high-performance telephoto zoom lenses for the EOS R system already, together with with the RF 100-300mm f/2.8 L IS USM — a first-of-its-kind optic. If, and the phrase “if” is doing important heavy lifting, Canon launched a 300-600mm f/2.8-4.5, photographers would have 100 to 600mm lined at f/2.8-4.5 with simply two lenses and no gaps. Granted, a 400-600mm f/2.8-4 would obtain virtually the identical protection, albeit with a sooner aperture vary. The mirrorless age has included a whole lot of novel lenses throughout all methods and focal size ranges. Nonetheless, maybe no phase has loved as a lot fascinating engineering because the telephoto vary. Past Canon’s attention-grabbing RF 100-300mm lens, it has additionally launched RF 800mm f/5.6 and RF 1200mm f/5.6 unique prime lenses, and the RF 200-800mm f/6.3-9 zoom. The competitors has been busy, too, with Nikon launching 180-600mm f/5.6-6.3, 400mm f/4.5, 600mm f/6.3, and 800mm f/6.3 lenses for the Nikon Z system.
Canon shooters are undoubtedly crossing their fingers that these attention-grabbing new patents end in a brand new lens or two sooner or later, though solely time will inform. Picture credit: Canon
