I’ve owned a Sigma DP2 Merrill for about a year now. I was so impressed with the image quality that I jumped at the chance to grab its bigger brother, the DP3 Merrill, when they went on sale recently. I had a chance to try out the DP3 during a recent visit to Rocky Mountain National Park. The camera layout is much the same as the other two Merrill compacts. A couple of cosmetic changes have been made. The lens cap is a better pinch design and of course the camera is physically bigger due to the longer focal length (75mm equivalent vs 45mm). The camera still takes forever to write a RAW file but its autofocus does seem a bit quicker. The camera can focus much closer than the DP2 to allow for macro closeups. Image quality is again stellar on the DP3. Color correction is a little tricky in the Sigma software but can easily be done in post using Lightroom or Photoshop.
I tried out several subjects on my trip to Estes Park. I shot an old barn in Longmont on the way up. 
I then hiked to Dream Lake in the park. Clouds obscured the sunrise but interesting patterns were everywhere in the ice and snow. The wind was howling, too! I walked around Bear Lake and found some interesting ice flows. Finally, I hiked to Alberta Falls. Not much to look at in the winter, but there were some cool animal tracks in the snow.
