On the Bench
The Putora Sharpness Chart test showed remarkable clarity.
The sharpness bar is shown in the following figures, without reduction. The sharpness falls off in the 9 range, which is very good. The test was a bit sharper than the previous SLRs I have tested. This is consistent with having 10 megapixels.
Gray levels (on the Putora Chart) were consistent with what I have seen in other digital cameras. There is a tendency to be a bit soft.
The Macbeth Color Checker test results are shown below. Like the other cameras I have tested, it is low contrast, and a bit under-saturated.
The second photo (below) is a scanned version of the Color Checker where I made adjustments to have it look as close to the original (on my calibrated Sony computer monitor) as possible.
The dedicated Gray Scale Chart showed good results. A bit low in contrast.
The Q-60 Color Target result is shown below. It is cooler in color and with less saturation than the scanned version, in the second photo. However, these differences can be adjusted in a photo editor, and all of the detail is there, which is the most important thing.
The Sigma SD10 camera is a great product. For $1,600 you get the camera, two nice lenses, more than 10 megapixels of resolution, and macro capabilities that surpass just about anything out there. I think the other camera companies would be wise to consider the Foveon technology or other vertically stacked pixel sensor technology. Otherwise, they may be left in the dust.
