What might be a good compliment to the FA 20~35 zoom for the istDS? I'm compiling a wish list, and would like a relatively fast, high-quality zoom that extends the range of the 20~35 to about 100mm or so. I'd prefer an FA rather than a DA, and am not looking for kit lenses or low quality consumer glass - something comparable to the 20~35 or better, preferably fixed aperture.
Suggestions welcome - oh, not Sigma ... Thanks! Shel
