In another photography forum I was advised to take the uv filters off.
"UV filters (on digital) are for hazardous duty use only. Leave them off unless strictly necessary. Your sensor has a UV filter bonded to it.

What are your thoughts?

They use Tiffen and Hoya filters.
Cheap filters, one should never use.
Have you ever put a Tiffen on a white sheet of paper? That yellowish smear.
Wouldn't want that in front of my lens.
A really good filter, like a B + W is clear and of high optical quality. And if its multicoated, you have almost no loss of light and reflections.
The test set-up with desk lamps and cheap filters is a joke.
Have they measured the angle of light in their "flare test"? How directional is the light from a desk lamp? Can they repeat the exact same angle? I really don't bother with that kind of weirdo tests any more.
If science would work that way, we'd all be dead.
As for me, I always have an UV filter on my lens.
For example, to keep UV and haze at bay.
And to protect, of course, also from dust, which my particular lens needs.
PS: some lenses, like the Canon 17-55/2.8 IS suck in dust if the front element is not covered by a filter.
