Michael, many thanks for the Sigma DP2M review! I'm particularly pleased to note that you've recovered to the point of being able to do the testing/comparisons and writing, so as to post this review for the rest of us. I've been enjoying my DP2M for the past week, but had no idea how well it would hold up in the particular comparisons you made. The biggest problem I have with the Sigmas is the SLOW write times. You really have to be careful not to turn the camera off while it is laboriously getting the information to the card. But I do enjoy the results. You rather strongly suggested there's been a firmware change from the SD1 to the SD1Merrill. I purchased the SD1 when they reduced the price, especially to work with infrared (but I have even more enjoyed using it for color). Sigma stated that the two cameras would be identical except for the Merrill name on the front. Now I'm wondering. Perhaps a firmware update would be available. At any rate, I've enjoyed seeing and benefiting from the progress Sigma has been making with the Foveon sensor. Again, many thanks for your continuing efforts to inform and enlighten us all. --Barbara
