Before the arrival of the Leica “Noctivid” (see separate post, https://binocular.ch/leica-noctivid-8×42/), Leica had updated its longtime Ultravid HD series with a “HD+” edition, featuring different glass and coatings and boosting transmission by a few percentage points. The difference was actually not that remarkable, because the Ultravid had been an excellent binocular even before the update, favoured by many demanding birding and wildlife enthusiasts. Today, the Noctivid takes Leica’s top spot in terms of optics, but mechanically, the Ultravid – or “UV HD+” as its often called – is hard to beat, and in terms of ergonomics, this is still one of the top instruments available. Many nowadays prefer flatfield images with higher edge sharpness and therefore would rather use competing instruments from Zeiss or Swarovski, but others praise the UV HD+ for its intense, color saturated image and good contrast.
