[QUOTE="Gamesniper19, post: 2204597, member: 95013"] My takeaway from this well documented data. Like magnification, like performance = like weight and build quality. There is a reason most high performance optics that provide useable magnification above 24X all weigh about the same (+/- a few ounces) To get that performance the industry is telling us the scope has to have certain types and amount of glass and certain internal working parts. If a manufacturer could get that equal performance using materials that were 25% less weight, my sense would be that they would. Example: Nighforce tried and as much as I love what they do, the NX8 loses optical clarity above 24x. My thing is on a 9lb fully custom hunting rifle, one that has the capability to reach out 1000 yards + with match grade 1/2 min or better accuracy, use like grade optics. Pick one and if it weighs 4-6 ounces more than some "lightweight" glass - 90% of the time you wont care that your rifle weighs 9 lbs versus 9.4 lbs. Can you find an outlier, sure you can. There always will be e.g. the Leica PRS...but I know no one that shoots PRS with one. Unless Leica sponsors them. To answer your question on 525 v 624. I called Kahles because side by side I could tell no practical difference in the glass between the models. I am not sure to the naked eye that many people could; Kahles confirmed that top end HD glass reaches about 2.1 megapixels of resolution and its hard to get much more. The human eye can only see so much acuity and its a varying measurement based on multiple factors that cannot be standardized due to whether a person has 20/10 or 20/30 vision and can many times see "better" than a scope can transmit so there is a point of return that we cannot perceived. The big difference is light and color transmission. The glass's ability to filter and transmit light in the 93% + range is a big factor in perceived clarity. Add in the types of multi coatings applied to the glass which can accentuate the impression of more clarity, to a point. The quality of the coatings matters. Its all important. More light, more clear, more resolution and more, more, more and more etc... Function wise Kahles told me the 525 has updated internals but what exactly they updated and how, they would not tell me. IME if a scope tracks reliably then the internals work. I set up an tracking board and tested all my 624s and no matter how many times I spun the turrets, they were spot on. I mean perfect. Confidence now abounds when I lay down behind them and dial dope.
