Features:
With the large bayonet diameter and short back focus distance of the EOS R system, as well as special lenses such as aspheric lenses, UD lenses, and advanced coating technologies such as ASC, new lens with a constant maximum aperture of F2.8 provides great expectations. The high-level optical performance is also equipped with IS image stabilizer and Nano USM drive motor suitable for photo and video shooting.
lenses also have the high reliability of Canon L-class lenses

RF24-70mm F2.8 L IS USM lenses use a waterproof and dust-proof structure, which enables high reliability in harsh shooting environments. At the same time, the lens also incorporates anti-fouling fluorine coatings with better oil- and water-repellency, which, while bringing good light transmission, can more easily wipe off water droplets or oil stains attached to the lens.

Describtion:

RF24-70mm F2.8 L IS USM, large aperture, standard zoom lens shows its power in RF series

　　The EF24-70mm f / 2.8L II USM is a classic and versatile zoom lens that is versatile and popular in the Canon F2.8 zoom lens series. Today, this classic continues into the RF lens family. In addition to the easy-to-use zoom range, the new RF24-70mm F2.8 L IS USM also significantly enhances the product's appeal by achieving higher optical performance and functional design including IS image stabilizer and Nano USM. It is a new type of commonly used zoom lens in the EOS R system, suitable for a variety of shooting scenes from street view snapshots to landscapes, portraits and short films. It continues the high-quality features of Canon L-class lenses while maintaining a compact design and high use Reliability and other advantages.

Generally, aberrations occur due to the refraction of light, and the image quality is therefore reduced. The EOS R system uses large-caliber bayonet and short-back focus distance characteristics, so that large-aperture lenses can be placed near the imaging surface, thereby reducing light refraction and the aberrations caused by it, achieving higher image quality, and making the lens as a whole Become more compact. In addition to the above advantages, the RF24-70mm F2.8 L IS USM also significantly corrects a variety of aberrations by adding 3 glass-molded aspheric lenses and 3 UD (ultra-low dispersion) lenses to achieve full zoom Within the range, high-resolution performance from the center of the screen to the edges. In addition, the lens also uses the ASC air spherical coating technology developed by Canon, which uses the characteristic of air with a refractive index lower than that of optical glass. By including a certain proportion of air in the coating, a low refractive index is achieved, especially for nearly normal incidence Light can suppress glare and ghosting that impair image quality.

　　Canon RF24-70mm F2.8 L IS USM lens uses 15 groups and 21 lens structure. By optimizing the optical design, the closest focusing distance of the lens at the 24mm focal length end is shortened to about 0.21m compared to about 0.38m of the EF24-70mm f / 2.8L II USM. The closest focusing distance at the 70mm focal length end is about 0.38m. The maximum magnification is determined by Increase from about 0.21x to about 0.3x (at a focal length of 32mm). The shorter closest focusing distance can help the photographer to make close-up shots with more prominent subjects, achieving powerful visual effects. In addition, the lens uses a 9-blade EMD circular aperture structure, and the point light source in the background of the shooting frame can achieve a blur effect close to a circle.

In terms of appearance, the Canon RF24-70mm F2.8 L IS USM lens, like the RF15-35mm F2.8 L IS USM, uses Canon's new L-class lens design style, which is more atmospheric and simple. The lens is approximately 125.7mm in length and 88.5mm in length and weighs approximately 900g. The filter diameter is 82mm as RF15-35mm F2.8 L IS USM. It can easily share filters of the same specifications. While improving the convenience of use, it can also reduce the number of filters purchased.
