EOS 4000D focal length magnification factor

EOS 4000D DSLR

What is the standard (in 1x) focal length for this camera? For example, the standard lens for a 35 mm film camera was about 50 mm. A 150mm lens would give about 3x magnification and so on.

The closest lens would be a 35mm from Canon. But a 30mm lens would be a standard lens for an APS-C camera.

I was just wondering. In film cameras, the "standard focal length" was about equal to the diagonal dimension of the frame on the film. For 35mm film, this diagonal was 50mm.

Thanks.
