There is no inherent reason why mapping and software correction of a digital image cannot be used to remove all sorts of geometric abberations and uneven illumination. Indeed, a Photoshop plug in for each specific lens could do the job. Some early ultra wide angle lenses did this in an analog way by using a graduated filter to correct for light fall off at the edges of the frame. Your eye does this by adaptive correction of the highly distorted image on the retina. Leica may, at last, be entering the 21st. century. Larry Z
