Did anybody try to compare the results of Foveon matrices and other brands? I understand it's not an easy job and there will be many critics of each step of this procedure. But most of reviews completely omit Sigma in objective tests and measurements of various properties of matrices and whole cameras. The most important question: how to get an objective measure of specific color flavor of Foveon that differs it from other brands? Many fans of Foveon feel it but can't formulate it in quantitative measures.
