Sorry if you took my post as a Nikon vs. Canon thread. Anybody who knows me, knows I do not think that way. I love both systems. I've still kept all my Canon long glass (and the fab 35L) and am just waiting for the next 1 series body to hit the market. I was only stating a fact, that the 14-24 is not "round" wide open, that's all.
And of course the 14-24 is bigger, it's a zoom after all. And while the 14 is smaller, I wouldn't consider it small enough to fit in a pocket, unless it's a pretty big jacket pocket. But I don't buy lenses based on what pocket they will fit in. As far as a filter is concerned, I see no need for them on wide angle lenses. I have a couple of CP filters, one for the 300 f2.8 and another one that will fit the 70-200 among other lenses, and I almost never use it. I have been sorely tempted to get a 3 stop soft ND filter though.
