Canon (China) Co., Ltd. announced the launch of the RF135mm F1.8 L IS USM full-frame large-aperture medium-telephoto prime lens, which is a professional portrait lens, suitable for business portraits, Indoor sports, still, life, and other subjects shooting. This is also the first time Canon has equipped a 135mm focal length prime lens with optical image stabilization.
The RF135mm F1.8 L IS USM is an RF bayonet lens, which has the advantages of a large bayonet diameter and a short rear focus distance of the EOS R system. Canon has equipped the lens with 3 UD lenses and adopted advanced coating technologies such as ASC. And the NANO USM drive motor suitable for photo and video shooting, equipped with 9 circular aperture blades, weighs about 935 grams, and measures about Φ89.2×130.3 mm.
Canon RF135mm F1.8 L IS USM has a certain close-up shooting ability, the closest focusing distance is about 0.7 meters, and the maximum magnification is about 0.26 times.
When the RF135mm F1.8 L IS USM is used with an APS-C format model (EOS R7 or EOS R10), a focal length of approximately 216mm can be obtained, making this lens a telephoto lens.
The optical structure of the RF135mm F1.8 L IS USM lens is designed with 17 elements in 12 groups and uses 3 UD lenses with low refraction and low dispersion characteristics. Officials say that the UD lenses used this time have abnormal dispersion characteristics like fluorite, 2 pieces of UD lens can have roughly equivalent performance to 1 piece of fluorite, and can effectively reduce axial chromatic aberration and magnification chromatic aberration.
The RF135mm F1.8 L IS USM lens also uses ASC (Air Sphere Coating) coating technology. It is also the first lens with IS image stabilization among Canon's same focal length lenses. It has 5.5-level optical image stabilization. When using a shaken EOS R series camera, can achieve up to 8 levels of collaborative image stabilization.
The RF135mm F1.8 L IS USM also supports the breathing effect correction function, which can suppress the angle of view change when the focus is shifted from front to back or from back to front during focusing.
The RF135mm F1.8 L IS USM lens is also equipped with a multi-function control ring. Users can assign functions such as aperture, shutter speed, ISO sensitivity, or exposure compensation to the control ring of the lens according to their habits, and turn the control ring to adjust the corresponding settings. , thereby greatly improving the convenience of operation. In addition, the RF135mm F1.8 L IS USM is also equipped with a function button of the 2 Canon lenses that was only used on professional super telephoto lenses in the past, which can be assigned various functions and can be used as an AF stop button in the initial setting. use.
RF135mm F1.8 L IS USM High reliability and good shock resistance. The movable parts such as the operation ring and the switch are equipped with a waterproof, drip-proof, and dust-proof structure, which improves the reliability and durability of use in different environments. In addition, the anti-fouling fluorine coating is applied to the front lens, so dust and stains are not easily attached, and oil stains on the lens can be easily wiped off with a dry cloth.
The Canon RF135mm F1.8 L IS USM lens will be available in January 2023, priced at 15,999 yuan.
