I was convinced early on that using A UV filter was a good idea. Primarily, the argument had to do with protection of the front elements of my lenses. My opinion on this subject has changed, however.
In part that has come about for one of the reasonspoints out in his latest post over at Photo Focus. (See the link below) You're going to put a $35 filter on a $1000 lens–REALLY!? In addition, I have found in practice that dust gets trapped between the filter and the front element on my lenses. A third reason for my change of heart is that I generally don't remove the UV filter when I want to add a circular-polarizing or other filter. That means filter stacking and can result in increased vignetting and greatly adds to the chance that lens flare of one type or another will adversely effect photo quality.
So my position on UV filters? Just don't do it. Surf on over to Photo Focus and see what Scott thinks.
