One has to find the perfect distance? I thought it was only black-outs that would be the problem when elaborating with this distance (and the FoV for those wearing glasses).The bins in which I have noticed the off center sharpness effect have had comparably wide FoV. Not sure if that has anything to do with it. But maybe the EP has been optimized for another model. I should mention that after extensive testing I think I have seen a link between the direction of sun illumination of the general view and the side of the binocular view that appears sharpest, i e if light comes mostly from the right, then the right side gets a tiny bit sharper than the center. It still feels like a contrast thing, but "sharpness" is a combination of things.</blockquote>
