Thought I'd post some comparison pics. Finding real world comparison tests seems to be hard to come by.
Just got a Burris Black Diamond, wanted to get another scope with higher power for woodchucks/1KBR.. and couldn't wait for the 6500 to come out. I found the pics to duplicate overall what my eyes see through the scope. In all three cases the eye can pick up more detail than is shown here.
What I did was set each scope for best clarity. Then set a digital camera up behind it until it was in the center of the focal range. I took five pictures through each scope and only kept the best one of each. Then I cropped an exact 1000x1000 pixel circle of each and resized it back down to 500x500. That is why the Leupolds have a darker ring around them, The focus range was back a little farther.
I just mounted the Black Diamond and should get to testing it this week. One surprising thing I found with the Burris was that the focal region was more forgiving/easier to locate target than the other two Leupolds in the test.
Will do an overcast/twilight test to see if the brightness/saturation of the Burris is helpful when it starts getting dark, or if it is just brightness without resolution. Hope my neighbor don't mind. Well heck his place is for sale anyway, listed on the web.
