I first thought the same regarding the sight picture, when looking directly at the centre of the ret the edges do appear slightly blurred but I found if I looked at the edge of the image they were, infact crisp and clear. I put this down to the field of view being so wide that the edge of the sight picture sits in our peripheral vision rather than in the centre like it does on a conventional scope. More a problem with the way our eyes work, rather than with the scope itself.
