Canon RF10-20mm F4 L IS STM ultra-wide-angle zoom lens release: five-stage anti-shake, weighing 570g
Thanks to the independent photographer of CTOnews.com, Hippophae rhamnoides, Daniel Wu in South China, and the clues of turnip peel! CTOnews.com October 11 news, Canon announced the launch of a new RF10-20mm F4 L IS STM lens, which is expected to go on sale in late October.
This is an ultra-wide-angle zoom lens. Compared with the EF 11-24mm f / 4L USM, the RF10-20mm F4 L IS STM is smaller and lighter and weighs about half as much.
The diagonal viewing angle of the focal length of the 10mm is about 130 °, and the coverage area of the 14mm is about 2 times that of the 14mm. When used with an APS-C frame model, it is equivalent to a 16-32mm focal angle and is a classic focal length of a wide-angle zoom lens.
The lens adopts 12 groups of 16 optical structures, including 1 UD aspheric lens, 2 UD lenses, 2 aspheric lenses, 1 super UD lens, and uses SWC subwavelength structure coating (2 sides) and ASC coating (2 sides) to effectively suppress glare and ghosts in wide-angle lenses.
The lens supports level 5 anti-shake, uses a circular aperture of 9 blades, and has a maximum aperture of constant F4, with a nearest focusing distance of about 25 cm. In addition, the new product introduces peripheral coordination control in the RF lens for the first time, using cooperative anti-shake with models that support anti-shaking of the fuselage, which can more effectively compensate for the peripheral jitter that was difficult to compensate before.
Canon RF10-20mm F4 L IS STM lens is also equipped with guide screw STM stepper motor, lens operating ring, switch and other movable parts are equipped with waterproof drip dust-proof structure, and the front lens uses anti-fouling fluorine coating.
