In the previous comparison, I promised to shoot and hand in further photos with the Sigma SD1 and the DP2 Merrill using a tripod. I tried to adapt the image sections as well as in any way possible but it turned out to be trickier than I thought, especially because the 30mm of the DP2m is slightly more wide-angled.
I am not sure whether it is the aperture 8, but the two lenses have a comparably high resolution in the middle of the picture. The upper one was shot with the SD1 and the 30mm f1.4 EX, the lower one with the DP2 Merrill. I maintained the same order with the 100% crops.
Looking at the corners, however, the DP2m’s 30mm f2.8 is clearly superior to the 30mm f1.4 EX. And that is despite the fact that I stopped down to f8.
For some strange reason, Flickr refuses to link to the correct size. Simply click on the two crops to view them in full size on Flickr.
One discipline where the 30mm f1.4 is ahead by a nose is bokeh and rendition when shooting wide open. In the following, each first picture was shot with 30/1.4 at f1.4, each second picture was shot using the same lens at f2.8, and the last one with the DP2m at f2.8.
