Canon RF 24-240mm F4-6.3 IS USM is an Auto Focus (AF) SuperZoom lens with 35mm FF max sensor coverage. When mounted on a 35mm FF sensor camera, it will give you an FF equivalent focal range of 24 - 240mm. With a max aperture of f4 at 24mm, we can not consider this lens fast on wide end but f4 at 240mm is not too bad for tele end.
Canon RF 24-240mm F4-6.3 IS USM is not a weather sealed lens, so you have to be extra careful against rain and dust.
