I have one of these as well (3-12x34 with SCB reticle) - I love it although the field of view is so huge that it feels like you are shooting on half the magnification that you actually are. I have noticed that when you are at the lowest level of magnification there is a degree of 'fish-eye' distortion. You only notice this if you as panning around but it is definitely there. Doesn't remotely affect accuracy though...
