Digital cameras made in the last 15 years all have built-in UV filters on the sensor. There is no need for an external UV filter. It is another source of optical degradation & chromatic aberration. The only possible purpose it serves is protecting the front lens element. That can be done very effectively by using the lens hood turned the right way.
This is why I said it's personal preference. No one uses a UV filter for the original purpose on a digital camera - they ONLY use it for the protection of the lens.
Some folks believe that putting a UV filter on the lens protects the lens and is worth any degradation that might occur. Others believe that a lens hood, proper handling, etc. will better protect the lens without any degradation.
Those two camps tend to be VERY split.
