Originally posted by pathdoc For the 15-30, I don't like the inability to fit a filter. And it's not just a question of ballistic protection either; there's ND, ND grad and a whole lot of other things one might wish to do...
Totally agree - this is disappointing. I use a polarizer frequently on landscape shots, and ND occasionally. If we get a high-quality prime (3rd party or pentax) in the 18-21 range that can take filters I'll probably be more likely to go with that and forego the 15-30 - flexibility sacrifice notwithstanding. At the very least this will give me pause before jumping in head-long.

True, but at a significant size/weight/convenience sacrifice (although, of course, the lens itself is big and heavy, too, so maybe if one already has it the "horse is out of the barn" in this regard)
