Oddly enough that's when I expect to get the most benefit from one. I often photograph subjects with highly-polished curved and glossy surfaces, under bright California sunshine. An extended highlight (most often seen when shooting with the sun in front of me) can be enough to cause problems, especially with the *ist-D. While the lens hood on the 80-200 is usually enough to keep the sun off the front element of that lens, the 28-105 isn't as well equipped, and a 58mm filter would also get used on a few other lenses. For that size, at least, I think I'll stay with a coated filter.
