This was shot with an F100 using a Tokina 20-35 F2.8 Zoom set at 20mm. I used a circular polarizing filter to darken the sky. however the filter vignetted, so there was a fair amount of photoshop work that went into cleaning it up.. The blur was caused by a 1/15th shutter speed. See http://www.shooter.net/0162_002.story.html for more details.
