Quote: Digital sensors are not affected by UV anyway, so that filter is just for "protection" as I assume you are using it.
If I remember correctly, the sensor has a UV filter layer over it; but I might be wrong.
I use a UV filter (when not using a polarising) for protection, following recommendations from long ago. Occasionally, I forget to put the lens cap back on before putting the camera in my bag and the filter may be helpful then. But I have never scratched a lens. Even when I took a tumble a few weeks ago, the hand carrying the camera went straight into the air, to protect it, and I took the impact entirely on the other side of my body.
