This was the beginning of my optics education. Since then I compiled this kind of info for at least fifty optics; spotting scopes, binoculars and rifle scopes.
11/13/10 Bushnell 6500 4 ½-30X50 mil dot, Swarovski Z5 5-25X52, Nightforce NP-R2 12-42X56
The sky was totally overcast with an occasional sprinkle. That takes care of the weather. Now the optics.
I purchased my first Bushnell 6500 4 ½-30X50 mil dot in 2009 for $750. I sent it back for warranty work because it was blurry above 25X. When it was returned it was great on the top end but the lower magnifications were blurry. I returned it to Bushnell for a refund. After a few months I purchased another, the present mil dot one for $620, which is better than any other scope I compared it to for daylight hunting; except my Nightforce. I figured by then the "pipeline" of the originals was empty and the problem solved units would be available.
At the shooting range I have compared this Bushnell with many Leupolds, Burrises, Nikons, Swarovskis, and others. None so far are as sharp or bright in sunlight as this Bushnell except a Minox 62 spotting scope. With both set on 30X the Minox produced a barely sharper image. Since none were as good as the Bushnell and none were as variable as the Bushnell I decided to purchase a more competitive Swarovski to compare with. I figured the z5 would smoke the 6500. I already owned the 12-42X56 Nightforce in the following comparison.
I compared a Swarovski Z5 5-25X52 ($1,675) with my Bushnell 6500 4 ½-30X50 Mil-Dot ( $620) and my Nightforce NP-R2 12-42X56 ($1,440). It took about two hours to complete the comparison. I made an "eye" chart with five lines on an 8 1/2X11 copy sheet, laminated it to keep it dry, and taped it to a cardboard box. The lines are 9/32" (.281") wide with 9/32" spaces between the lines. After setting the box out I drove down the road a ways.
The test idea was to see at what range I could no longer see lines, but a grey rectangle, and then turn the scopes up and focus them and record the magnification setting. After reading the following and think about the cost, which would you keep? After this comparison I returned the Swarovski for a full refund. Last week I ordered another because it is lighter than the Bushnell; but it does not compare with the Nightforce.
Here are the yardages and magnification results:
