Or..... Leica smashed it out the ball park 20years ago...But I see little enough difference to spend the huge increase."So we have a situation where the Ultravid HD doesn’t differ markedly from the Ultravid BR and the Ultravid BR is an almost identical copy of the Trinovid but closed in a lighter casing. It seems that for almost 25 years, Leica haven’t introduced any innovative optical solutions to its key series of binoculars. Of course, the weight reduction and hydrophobic coatings are appreciated, along with a slight transmission increase or a tad wider field of view.
Still, such a reputable company should have done better, especially if you take into account the length of the period of time we are talking about. As a result of such stagnation, Leica devices started to compete with each other: you can still buy a second-hand specimen of Trinovids in mint condition for half the price of the new Ultravids HD-Plus."
