I think the clarity is awesome. My whole family is strictly leupold. Mostly the older vx2's, and vx3's. I was the first to break the bank and get a MK4. Im glad I did is all I can say. The clarity, brightness, crispness around the edges is superb. Looking through the scope to me, actually seems to brighten the whole world up, its crazy how bright and crisp the edges are. Nightforce and S&B, and IOR all have really nice glass as well, but in my opinion, the MK4 glass is right up there.
