UV filter causing interruption in long exposures.

I've come to the conclusion that if a shot is to be taken at anything smaller than F8 ,that the UV filter should be removed .
I notice it a lot with exposure that are longer than a second.

Is this my UV filter ,or is it just the traffic marks on the filter ?

Examples? I've never come across any problems using a UV filter for long exposures. I tend to keep the filter on at all times to protect the lens.

There are reports of certain UV filters and lens combos causing moiré type patterns to be obvious in the Oof areas of pics, if that's what you mean. I remember reading about it in one of the nerd tech groups in Flickr.
Rather worrying I was actually invited to join them when it was a private group

Thanks for the replies ,I only really notice it when theres detail in the backround. As soon as I take off the filter ,the backround is nice and sharp.

I don't like taking off the filters myself ,but it annoys me if I don't.
Anything from F8 to F16 shows up the bluriness.
