Message: <blockquote data-quote="Inquisitor" data-source="post: 3372748" data-attributes="member: 129508">Reading the charts has made me think...Since the introduction of HT glass I have seen an increase in the review terms of "pop" "sparkle" and "cleanness"It seems the terms are still used even in binoculars that are not winning the transmission race. If one reads enough reviews one can see the terms ascribed to glass with HT technology and consciously excluded from a glass with higher transmission but without the HT labeling. Is there a placebo effect in place here ? Or does it have more to to with the shape of the transmission curve and what colors are accented and suppressed?  I struggle less with the sparkle comments given to the Zeiss HT because the high transmission data appear to more nearly support it but this Leica HD+ has me scratching my head.Is there more to extreme clarity than high transmission? I don't doubt for a minute that a HD+ is indeed awesome and improved but what makes it more sparkly than a bin with higher transmission? I understand the spike in reds for the famous Leica art images, blacker blacks, and higher macrocontrast.....but sparkle has me lost.Since I can't get my hands on one locally, I am very tempted to order and try a 7x42 HD+ out. I plan on listening to my eyes and hands but I am just geeky enough to want to know why I/we see what we do.</blockquote>
