We have been here for almost a decade now.A few (may be 2 or 3) percent light transmission is all that this is about. Human eye percieves image brightness on a logarithmic scale not a linear sclae. Furthermore, image brightness is affected by so many other factors (e.g., contrast, color, etc.) that this would hardly be perciptible. Sad, but its true. We are at the apex of optical performance for binoculars.</blockquote>
