I don't know why there is a problem replying today, this is my third attempt.


Anyways, There is a question that often surfaces whenever this topic comes up. If you buy a nice lens with good glass why put anything in front of it.

A DSLR already has UV and IR Filtering built into it, so using a UV filter on your lens is kinda redundant. People do use them to protect from dust and scratches, however some will claim there is a trade off in doing that. Some people experience degraded IQ, and some even experience flares and reflections. The best option is a good quality clear or skylight filter if you use a filter at all just for protection.



I do use one myself when I go to the beach where there might be blowing sand and see spray. Otherwise I don't worry about a little dust or tree pollen that might get on my lens; That is easily blown off.


What it boils down to is how you use your camera. Outdoors in a harsh uncontrolled environment, or indoors in a clean controlled environment?
