Very pretty. I lived on the east side of Mount Sequoyah in Fayetteville for 15 years and saw some beautiful sun rises. Some of my favorites were during the ice storm of 2008.
I just got the Nikon mount and use it on my D7000, it exceeds my expectations and my expectations were high based on the reviews. I also got the usb dock but have made no adjustments as none were needed. DxO rates this lens as the unrivaled best APS-C zoom. Starting at 1.8 the lens performs amazingly well. I'd say pull the trigger
