Not arguing or being argumentative, but if one already has two zooms that start at 18mm, then buying additional zooms that have a wide limit of 1 or 2 mm more is not getting him much, maybe a little speed, depending on the lens. However, if the intent in purchasing is to use it mainly as a wide angle, then a fast prime makes more sense in my book, but then I'm not spending the money.
I hear "plenty fast" and things like that. How fast a lens is and whether it's speed is satisfactory is dependent largely on shooting conditions, is it not? I'd want the fastest lens available/affordable, because just when you think your lense is fast enough, it's not.
