You probably need to clean the autofocus sensor. Also try cleaning your lenses. I always keep a UV filter on my lenses and replace them about once a year. It's a lot cheaper to replace the filter than the lens.
Why do you need to replace the UV filter?? Isn't taking them off periodically and cleaning all you need to do. I use UV filters on my lenses but certainly don't need to replace them. I'm just curious...don't mean to imply anything but that.
It's personal preference. Could be the thought that the UV filter becomes scratched with time and it's better to replace it, or that after X number of cleanings, it gets a bit fuzzy, etc., that additional cleaning can't correct. There are more opinions on UV filters than there are on dogs in campgrounds.
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.
