UV Filters....Yes or No?

No (with qualifier)

I use a rubber lens hood indoors, and the packaged lens hood outdoors for protection. The only exception I would make is in a very dusty environment where the lens you are using does not change length externally. The ∑85/1.4 does not extend when focussing, although the inner section moves back and forth (but not the filter ring). This does cause a slight amount of air to move, and a filter of any kind on the front would create a (more or less) closed area that would help a great deal to prevent dust from getting into the lens and camera. Just to compare, I have the Minolta 85/1.4, and the entire front section moves a bit when focussing, including the filter. The lens becomes a piston, sucking and pushing air every time I focus.

For normal use in most environments, a UV or clear filter just creates another surface for flare.
