In appearance, the lens is quite simple; it is smooth from head to tail and only has a glossy black tone.
The remarkable point in the external design, as well as the operation of the RF 24-240mm f/4-6.3 IS USM, is the combination of the stroke ring and the parameter customization ring into one. If you don’t already know, Canon’s RF series lenses have a rotation on the body of the tube, allowing you to assign the desired function on it, such as Password, speed, ISO etc. for example.
With this “integrated” design, users can choose between focusing or adjusting parameters via a switch on the tube body. Therefore, if users want to adjust the focus manually, they cannot adjust the parameters on the body of the pipe.
Combining 2 rounds into 1 will cause some negative comments. However, be aware that reducing the rotation by 1 helps reduce the size of the lens, as well as reduce production costs, leading to lower costs. In the past, no DSLR lens had a rotation, but it did not cause any serious impact on the operation of the machine.
To prevent the lens from operating for a long time, the worn plastic joints lead to a “zoom slip”, Canon engineers added a lock button on the right side of the lens body, locking the lens lock in place at a focal length of 24mm when it is not in use.
The weight of this lens is 750g, which is quite light for a full-frame superzoom. When accompanied by a “lightweight” machine like the EOS RP, this apparatus will be a very suitable choice for trips.
According to Canon, using the RF 24-240mm lens included with the EOS RP body will be similar to attaching the EF-S 18-200mm f/3.5-5.6 IS lens and the EOS 800D body.
Canon RF 24-240mm f/4-6.3 IS USM is a telephoto zoom lens designed for its line of R-mount full-frame mirrorless cameras, equipped with 10X optical zoom and Nano USM engine to handle AF and allow both still photographers and videographers to fine-tune focus in AF mode.
RF 24-240mm F4-6.3 IS USM lens is applied with a new technology, Nano USM, which enables fast, accurate and smooth autofocusing even when taking photos or recording movies when the subject is moving in high speed. In addition, the lens also features a control ring that allows photographers to directly adjust shutter speed, aperture, exposure compensation, ISO, etc.
This is the first Canon lens designed for full-frame cameras featuring DIS (Dynamic Image Stabilization) equivalent to the 5-stop CIPA stabilization system. This feature is very useful when taking photos and videos in work environments with slight shake, or in low light, even at night without the use of a tripod.
The Canon RF 24-240mm F4-6.3 IS USM has the closest focusing distance at 24mm of 50cm and at 240mm at 78cm and magnification of 0.26x at 240mm. The optical structure of the lens consists of 21 layers in 15 groups, including an aspherical lens element and 2 UD elements along with 7 circular aperture blades. The lens uses a 72mm diameter filter and the largest diameter on the body is 80.4mm.
