Though the 11-16 is fantastic, Honestly, you don't have to chunk down quite that much. You can save 200 and get the 12-24 f4 and achieve almost the exact same thing for 310-350. Yeah, so it's F4. If you're shooting skiing, you're stopping down to f8-f11 for the most part anyways. Maybe more if you're not shooting with a filter. On top of that, you get more range. I'm definitely picking one up myself. when I decide it's worth it.
