[QUOTE="One Hole, post: 1419482, member: 90934"] There are standard optical test methods (ASTM, UL, CIE...) to quantitatively assess optics products without bias. Among the most critical attributes for sporting optics are; light transmission, optical distortion, color shift and reflectance/glare. Reputable manufacturers reference these test methods. When comparing different products check to see if they are tested to the same methods. this is the best you can do when buying without viewing. if you have different products side by side the simple test I like to perform is to select some text/object on a wall. Now walk away until the text/object becomes indiscernible. Repeat with option B, C... Which one allows you to clearly discriminate the sample at the furthest distance? This method effectively combines the critical attributes into what is really important - seeing detail at distance. many years ago I tried this test with pair of steiner military marine 12x50s (top drawer glass at the time) and a pair of "new" swaro 8x30s. I could see better detail at longer range with the swaros even though they were lower magnification. this due to better optical clarity which is the result of higher purity lenses and better polishing. hope this helps!
