There are lots of types of filters, so it depends what you want to shoot. If you mean just a filter for protecting the lens, they really aren't necessary unless using using the camera in conditions that could physically harm the lens.
Hello just got a 500d, do I need to buy a filter? If so which one do I need? Am a newbie! Thanks in advance
