There is some antipathy towards the use of UV lens filters for sure. I tend to agree.

There are strong feelings both for and agains the use of "protective" filters.

Digital cameras, have built-in UV filtering, so the only use is for "protection".

But UV filters are necessary; most every OEM camera has them, just on the sensor instead.

Unlike film, digital sensors have a mirror like surface. A flat glass element (such as a filter) that is parallel to the sensor can set up an infinity mirror effect. This isn't an issue when the filter is attached to the sensor.

I wonder if one mounted on the lens is more likely to degrade an image than one mounted on the sensor or behind the lens (in a filter holder, or a clip filter). I have cameras with no UV filters at all, but don't have the patience to try it.

With a modern digital camera, there is no need for a UV filter behind the lens.
