Canon has patented a 10-120mm lens with a constant maximum aperture of f/1.8 throughout the zoom range for cameras with 1-inch-type image sensors.
A new 12x optical zoom lens has been patented by Canon. This optic has been designed for cameras that feature 1-inch-type sensors. It has not been developed for interchangeable lens cameras, instead being created for fixed-lens shooters, such as the 4K-ready XC10 camcorder.
The patent in question is describing a 10-120mm zoom lens that features a constant maximum aperture of f/1.8 throughout the entire focal range. As it is different from the optic available in the XC10, it brings up the possibility of seeing it in this camera’s replacement.
Patent for Canon 10-120mm f/1.8 lens uncovered in Japan
The internal configuration of the Canon 10-120mm f/1.8 lens consists of 24 to 28 elements divided into 20 to 21 groups. The designs include multiple Ultra-low Dispersion elements as well as a few fluorite elements. As a result, the image quality will be high because chromatic aberration and other optical flaws will be greatly reduced.
Moreover, the patent application is stating that the optic has inner zooming and focusing mechanisms. As usual, this means that the lens will not extend its length when focusing and will not rotate its front element when focusing.
Both features are useful in still photography and in videography, so it will be welcomed by users regardless of their intended purposes. Either way, the lens will make its way into a fixed-lens camera, such as the XC10.
The Canon 10-120mm f/1.8 lens has been designed to cover 1-inch-type sensors therefore it will offer a 35mm focal length equivalent of about 27.2-326.4mm.
Canon may add this lens into the XC10 replacement
The lens found in the XC10 camcorder offers 10x zooming capabilities, a 27.3-273mm full-frame equivalent, and a maximum aperture of f/2.8-5.6. The patented optic is faster and must be taken into consideration for an XC10 replacement.
Canon filed for this patent on October 7, 2013, while it approval was given on April 20, 2015, shortly after the introduction of the aforementioned XC10 camera.
Although there are hopes for seeing it in a future camera, the company’s fans must remain cautious as the product might never see the light of day.
Nevertheless, patents are an indication of a company’s plans, so we invite you to stay tuned to Camyx for more information regarding this product!
