I would like to ask you if there is any difference between the photos taken by the camera with sunshade and UV mirror.

The hood is to prevent the lens from filling up when the backlight is turned on, that is, there is a large group of shiny ~~UV in the picture to block the ultraviolet rays. Because the film will be sensitive to ultraviolet rays, it needs to be shielded to avoid interfering with imaging. Adding UV will make the contrast of the picture stronger, just a little. In the modern digital age, CCD and CMOS are not sensitive to ultraviolet rays, so the function of UV mirror is only to protect the lens.
