Wide-angle zooms.
2 of Canon's freshly published patents are actually of what are described as compact wide-angle zoom lens. The lenses cover the zoom ranges of 15-28 mm as well as 17-30 mm. Both lenses also possess a constant wide max aperture of f/2.8. Canon presently creates 14-35 mm f/4 IS as well as 15-35 mm f/2.8 IS lenses in its L-Series along with comparable central duration ranges.

Lense installs.
The patents cover the visual style of the lenses and also do not indicate the lens mount. Having said that, the best very likely alternative would be Canon's radio frequency install. Additionally, Kengo Iezuka, that oversees preparation lenses at Canon, provided a meeting regarding RF lenses recently. During the job interview, Iezuka claimed, "There are still many lens that have not been actually discharged to the planet. I can not discuss the specifics, however there are lens with basic requirements, and also lenses along with standards that have actually certainly never been viewed just before and also nobody can easily imagine however.".
What our experts think.
Till recently, Canon has actually avoided other manufacturers coming from making radio frequency mount lens. Currently the firm is actually starting to open the market to other lens producers, Canon needs to have to always keep innovating. The brand new patents show that Analects is working hard to establish interesting brand new lenses for its radio frequency mount cameras. Nevertheless, as always, where licenses are worried, it is actually likewise necessary to bear in mind that the procedure is actually carried out primarily to protect technical advancement. The sign up of a license does not constantly lead to an item relating to market.
