Hi Peter, Now that's interesting! For those who have an interest and take the time to view this page realize that the Sigma SD9 digital camera used for these "tests" has an even smaller sensor than the Canon EOS D30/D6010D family, the lens factor is 1.7X. The reason I mention this is that even less of the problem prone areas of these Sigma lens' image circle will be visible in these "test" images. There is also no mention in the text if these are full frames (100% or some other res.), center or edge crops. These images are approx. 200x200 pixels and don't demonstrate much except how far down the Sigma lenses need to be stopped in order to get a decent image out of them when mounted on a Sigma SD9 digital camera. Is this a problem with the Sigma lenses that is being tremendously amplified by the Sigma SD9 digital body or is this typical for the Sigma lenses shown on the site? I KNOW that some of these Sigma lenses are much better than is being shown on this page but where is the problem? Lens or body? Anybody else have, used or tested the SD9?
