I’m sure you are getting tired of Cloud Gate shots. This is my last in the series and also my favorite. This was taken with my Leica M9-P and 21mm super elmar. What I like about it is the amount of detail in the buildings (click on picture to see full-size). The 21mm super elmar was built for sharpness from corner to corner and this image is a perfect example of it.
