Has anybody ever used a Zeiss Conquest scope?

These scopes cost about half as much as Zeiss other scopes. Since I believe you get what you pay for I imagine their not quite as clear as the higher cost models. How do these compare to say Leupold VX-3 or Burris Black Diamond? Or are they more on the level of Leupold VX-2 and Burris Signature scopes? Thanks for the info. Steve
