The Thing of the Moment Gallery and received an email containg the following question:
"Is your lens totally bogging?"
In defense of my totally bogging (filthy) (and MAGICAL Sigma 10-20) I have to say IT IS LENS FLARE! It's angle is so wide that UNLESS the sun is DIRECTLY at your back that it will sneak into every image. Or maybe it's because I took the photo after playing 'Hey, touch this lens' with my coworkers. You decide.
