I don't understand this thread. When I purchase a scope I expect it to be as clear on the maximum magnification as it is on the minimum magnification. My Bushnell 6500 4 1/2-30X50, Leupold VX6 4-24X52, Swarovski z5 5-25X52, and my March 2 1/2-25X52 are all clear to their max magnifications. I use a military optics chart 127 yard away to compare optical quality. When I turn up the Bushnell none of the others can keep up with it because it is great on 30X. All the others are great on their respective maximums.
The first Bushnell 6500 I bought was not a keeper because it was blurry above 25X. I returned it for a refund and purchased another. Then I purchased two more. I would not keep a scope that punks out in the higher magnification settings. By the way the Bushnell cost about 1/2 to 1/3 the price of the others.
