Canon RF24-105mm F4-7.1 IS STM丨Appearance
RF24-105mm F4-7.1 IS STM as a compact and lightweight lens suitable for daily shooting and carrying around, the lens weight Roughly equivalent to a bottle of mineral water, only 395 grams. When used with EOS R, there is basically no burden on the body, which is a good choice for users to carry and light.
The whole lens body is mainly black. In order to balance lightness and non-slip, the outer layer is made of high matte texture. Strength material. The two silver rings have the same color as the R series mirrorless single, and are highly consistent with the style of the fuselage.
two sides The switch is a conventional focus/control ring switch and IS image stabilizer switch. Simply put, it is a switch used to change the function of the front control ring of the lens, and the other is a commonly known anti-shake switch. This anti-shake switch is only for the lens, and does not affect the body’s anti-shake. When the IS image stabilizer of the lens is turned on, with the camera’s dual detection IS function, it can achieve a hand-shake compensation effect of up to about 5 levels.
RF24-105mm The focusing distance of F4-7.1 IS STM is 0.2m at the 24mm end and 0.34m at the 105mm end. The manual wide-angle end can reach a focusing distance of about 0.13m. The central macro focusing function can be used to make the front end of the lens closer to the subject , Get the performance of the surrounding greatly blurred pictures, and develop your thinking to create very interesting works.
used in front of the lens The switchable focus/control ring makes shooting operations more convenient. Switch the switch to “CONTROL” to set the shutter speed, aperture adjustment and other common functions in the body menu. The surface of the control ring adopts a special diamond-shaped non-slip design, which provides a good hand feeling, and can be operated blindly through touch, which improves the convenience of operation. The control ring rotates very smoothly and there is no action sound. The operation of the control ring will not affect the body recording during movie shooting.
RF24-105mm The diameter of the filter used in F4-7.1 IS STM is 67mm, and the lens uses an optical structure of 13 elements in 11 groups, including one aspherical lens.
The lens uses 54 With the large diameter of millimeters, the flange distance of the camera is greatly shortened, and the rear focus distance of the lens is shorter. Improve the flexibility of the lens optical design, use a short back focus distance, place a large-diameter lens near the image sensor, so that the periphery of the screen also has high image quality.
In order to further reduce the size of the lens, the RF24-105mm F4-7.1 IS STM uses an external zoom design at the 24mm end Keep 88.8mm, and the lens will stretch a part when using the 105mm end. You may be worried about the waterproof and dustproof of the lens. During the test of the real shot of the lens, it happened to be taken from the side of the road on a rainy day. During the process, a lot of rain dripped on the part of the extended lens body. When I was worried, I forced the lens back. At 24mm, it was found that the rainwater was blocked outside and did not enter the inside of the mirror body. There was no fear of water and dust.
RF24-105mm F4-7.1 IS STM, as an introductory hanging head in Canon R system, has excellent performance in terms of materials, control design, portability, optical structure, etc. It is already superb at its 2,999 price. Value for money. How is its image quality? Next, it will be used with EOS R body for evaluation in various aspects.
Canon RF24-105mm F4-7.1 IS STM丨Sharpness evaluation
Sharpness A lens is an important parameter. The RF mount enhances the flexibility of the lens’s optical design, and also enables high-quality images around the screen.
Sharpness test The method is to use the 24mm end and 105mm end to shoot with different gears in different stages, and take 100% screenshots of the center and edges to observe and compare.
Canon’s lens is not unreasonably praised, the 24mm wide-angle end imaging is excellent, the steel bar in the center screenshot is clearly visible, F4-F22 full range There is basically no degradation in picture quality. Edge imaging is the pain point of the wide-angle lens. The edge imaging of this RF24-105mm F4-7.1 IS STM is also very good, the distortion is very well controlled, the image quality is very clear, and the full aperture range can also maintain a good level. Next, look at the performance of the 105mm end.
24mm wide-angle end did not let everyone down, so 105mm will not lose face, only the most extreme f/32 small aperture sharpness has a significant decrease , The sharpness of F7.1-F22 is so high that even the small grids on the wall are clearly visible. After the sharpness test, the conclusion is that the ability exceeds the price. Thanks to the optical structure of the lens with 13 elements in 11 groups, including 1 aspherical lens, the high image quality at the periphery of the screen is effectively compensated for aberrations, the large aperture performance is improved, and the wide-angle end shooting effect is enhanced. Higher picture quality.
Canon RF24-105mm F4-7.1 IS STM丨Distortion evaluation
Lens distortion is a cliché The topic of this topic is generally generated at the wide-angle end. This time I tested 24mm and 105mm respectively. The lens correction is turned on by default. Let’s take a look at the results.
