Quote: my kit included 2 UV filters too - other than protection - what use are they at this point?
Not much. UV filters were created to filter out UV for films that couldn't handle UV light. That was solved many years ago, but the camera stores continued to sell them because they are a high profit item.
About the only time that they are useful is when you are at high elevations where there are higher than normal levels of UV radiation (like in the mountains).
There will be people who tell you that they are good to protect the lens. My feeling is that a filter is not going to help when you drop the lens on the face and shards scratch your front element, or warp your filter threads. About the only time I'd use one is for blowing sand or mist, but I don't any, so it never happens. I use a blower and microfiber cloth to clean my lenses.
