UV Filters. Do they do anything?

You can also look into Haze filters by Tiffen. Her's the website.

Haze 1 - Reduces excessive blue haze caused by UV light by absorbing 71% of UV. Great all-around UV control.

Haze 2A - Absorbs all UV light; reduces haze; maintains color and image clarity. Best for high altitude and marine scenes.

I use a Haze 1 and I see difference in my pictures, mostly in the mountains or near the water.
