Depending on your creative intentions, you may or may not want to be able to focus your lens when video is being recorded.
And if you want to record video while the lens is focusing, you need a lens designed to be quiet.
The 50mm f1.8 is not one of these lenses.
I can't comment on other 50mm single focal length lens.
Canon make two zoom lenses that cover the 50mm focal length, and are designed for silent focus. There's an 18-55 with STM in the name, and an 18-135 STM, which obviously covers 50mm.
The 55-250 mm lens also comes in a STM silent focus version.
Canon makes a 40mm silent focus lens. Is that close enough?
