What Mr. Gilbran's examples (Just ABOVE) clearly reveal to me is (1) better spatial resolution as evidenced in blades of grass against the light grey path (2) better contrast AND spatial resolution on the fire hydrant and (3) a more realistic appearance in shadow detail for the SIGMA DP Merrill images vs. the NIKON D800E images.
As for the color checker/Lightroom examples above I'm far less sanguine over any color channel weaknesses since these examples aren't from camera RAW results. the comment that SIGMA is attempting to "Hide noise" is pejorative in nature and as such should be ignored on its...Show more →
"Mr Gibran"...oh, I hate that!
"truth in sensing" Man, I can't wait until the election is over!!!
I've done a bit of back to back testing between the DP1M and the D800E with the 28 1.8G over the past week and, overall, the DP1M acquits itself quite well. A few things I have noticed though....when reducing the size of the D800E image to match that of the DP1M image, any advantage of the D800E's increased resolution is lost - no big surprise - and often the Sigma image will appear more detailed. But, if you interpolate up/ or print the DP1M to match the size of the D800E, the D800E image is obviously better and shows far more natural looking detail when the lens is up to the task.. That last point is important because I found that the Nikkor 28 1.8G is not always up to the task (mostly due to field curvature it would seem).
