I just returned from a three day trip to Las Vegas, Nevada and stayed in the El Cortez hotel on Fremont Street. I was testing the Sigma DP3 Merrill and the Sigma DP2 Quattro which Sigma has out on loan to me. I will be writing up a review pretty soon on my experience with the DP2 Quattro. It’s a nice camera. This cityscape was shot with the DP3!
