I am having a Sigma DP1, the unit of the local Sigma rep, to give it a test run over the weekend. I have to bring back the DP1 tomorrow. I shot yesterday with both Sigma DP1 and K20D without trying to make a direct comparison, today I tried to make more or less the same shots with both cameras to compare both.
The Sigma DP1 photos were taken in RAW and converted with Sigma DPP software.
The K20D photos were taken in RAW and converted with Pentax Photo Lab. I used the Sigma 10-20 as lens.
After converting, I resized the photos in Photoshop and gave all photos a 33% smart sharpen.
