Very nice photo! I like the sun star and the colors are wonderful. This is a lens I've considered before. I owned the old contax version but sold it after comparing the sharpness to Canon's 2 wide angle zooms and finding it similar. However, I regret that decision as I've moved onto a larger mp camera and the edges and corners are far better on the wide angle zeiss lenses.

Anyways, good luck with the contest. This is a great image. I hope you do well!
