Can you post a link for this? I have read Lecia made 200 changes when the HD model came out years back.
It is in the current issue. I haven't been able to find a link. Here is a quote from the article, it starts with the 1st sentence:
"I admit I was stumped to read that "200 innovative changes" had been made to the new Leica Ultravid HD-Plus. Previous Ultravids already were among the best, and since you don't incorporate electronics (like a rangefinder or ballistic calculator), how in the world can you improve them 200 times over? When I posed that question to Leica's marketing boss, Terry Moore, he grimaced, "We'll send you an email." "
"The press release arrived soon, but listed far fewer than 200 changes. Later I'd learn about such upgrades as plasma lens coatings, deeper eyecup click-stops and the addition of Teflon discs to ensure the focus mechanism remains smooth and functional to -25º C. What Leica chose to crow about, instead, was exactly what jumped out when we received an Ultravid HS-Plus 10X 42mm for testing: Despite optical performance that's better than ever these binoculars are the smallest and lightest in their class. That's a big deal to extreme big-game hunters, big enough to justify pricing that tops $2000.00."
The 3rd paragraph talks about the Schott HT lenses and prisms and glass with calcium flouride to correct CA and its higher light transmission and truer color fidelity etc.
The 4th paragraph begins: "And yet my 10X 42mm test unit was barely larger than many 32mm compacts. At 4.72" x2.68" x5.79" and 26.5 ozs., the German-made Leicas are at least a half-inch shorter and 3 ozs. lighter than competing models from Zeiss and Swarovski." . .......
The article is only 4 paragraphs long.
