What is the difference between 50mm 1.8 and 1.4 among Canon lenses?

The price is 1.4 pages more expensive. Why?

1.8 and 1.4 refer to the aperture value.
The smaller the aperture, the brighter the picture can be taken, so the price goes up.

Small aperture means it can receive a lot of light.
Then it looks much prettier because the picture comes out bright.

Small aperture values make it brighter, but they are also good for flying the background.
It allows you to focus on the person you're trying to take, the background is blown away.
