Duovid 10/15 x 50 coatings question (1 Viewer)

[Kiwimac]

So tomorrow I am spending some time at a dealer where I can compare the only demo Noctivid 10x available (had to ask Leica in Auckland to pretty please send them to the dealer down here) with the 10x SF from the Blue Square. He has those in stock.

One other binocular that has piqued my interest is the now discontinued Duovid 10/15 which is still available from new stock here.

What I cannot find I out is whether they have AquaDura coating or not. Does anyone know?

Hi Kiwimac,

The Duovids were introduced in 2002. And the AquaDura external lens coating, seems to be first mentioned in a 2007 catalogue.
FWIW, going forward from then while it's specified on various models, I couldn't find a mention of it on the Duovids.

The Aquadura coating seems to have been introduced in 2007, with the HD upgrade to the Ultravid line.
The details from a July 2007 catalogue:




And a demonstration from an early review of the HD upgrade by Derek Lovitch:
(see post #8 at: Leica 8x20 Ultravid is a gem! )



Along with Derek's preferred lens cleaning method:

Hydrophobic coatings do sort of work - you get some beading, but in my experience they're not as magical as the makers imply and viewing is still compromised by what droplets remain.

My Duovid 8-12x42 from late 2011/early 2012 doesn’t have AquaDura.

FWIW, anyone can add the hydrophobic chemicals to their lenses with an anti-fog wipe - here's an article on it. These coatings are just sprayed or wiped on, they are not permanently bonded to the glass like the anti-reflection coatings. So folks with older Leica or Zeiss binos, or those with current Swaro or Nikons, help yourselves:

Does anyone know if the coatings of the Duovids were upgraded over the years it was available..
