Consistently smooth focusing –
whatever the temperature
The mechanics for the Ultravid HD focusing have
been further refined. As a result, focusing is even
smoother and remains free of play across the entire
range. Optimized material pairings and gliding discs
made from extremely tough, high-performance plas-
tic are used. In cold conditions, the conventional
greased focusing mechanisms sometimes only work
with difficulty, and at higher temperatures they move
too freely. Furthermore, these focusing mechanisms
can feel “sticky”, and at higher temperatures there is
even the danger that grease can escape and run on
the lens. With the optimized Leica focus, these risks
have been eliminated. In the new Ultravid HD models,
it works practically without any lubricants. So even in
extreme temperatures, it is always fully functional –
with a constantly optimum degree of smoothness.

Imitating nature: Leica AquaDura™
The models of binocular and spotting scopes with
the new HD and APO lenses are now fitted with Leica
AquaDura™, a “hydrophobic coating” which with its
water and dirt-repelling properties, ensures clear
visibility even in poor weather conditions. As with the
leaves of the lotus plant, droplets of rain simply roll
off the lens, and fingerprints and dirt particles are
much easier to remove. In addition, thanks to its
increased abrasion resistance, Leica AquaDura™ will
protect your valuable lenses from damage even more
effectively.
Fluoride lenses
With the help of new fluoride (FL) glass, in Leica HD
and APO models the color fidelity and contrast of
images is further improved. Optical FL lenses are to a
large part made up of calcium fluoride, a mineral with
acrystalline structure. Unlike conventional optical
lenses, this creates a very low level of dispersion
(light scattering) and corrects aberration (imaging
errors) significantly better. So as a result, the viewing
experience is more natural and impressive than it has
ever been before.
In a direct comparison on a Leica test binocular, the advantage of
Leica AquaDura™ is made particularly clear: On the coated objective on
the right the rain rolls off; in contrast, on the uncoated lens on the left,
rain drops and dirt remain attached.
left: Without fluoride lenses, troublesome color fringing can occur, and so
contrast and sharpness appear weakened.
right: The new optical Leica FL lenses reduce color effects to a minimum –
and so nature is rendered clearly and without distortion.

New ideas for even better
visibility Leica represents innovation.
Our own outstanding achievements in
terms of lenses and mechanics are being
continuously monitored and the standards
set even higher. Which is why Leica binocu-
lars and spotting scopes are always “state
of the art”. Our latest innovations are prov-
ing this once more – Leica HD and APO
lenses bring you impressively even closer
still to nature. The sum total of new inno-
vative features therefore makes the binocu-
larsof the new Leica Ultravid HD genera-
tion and the new Leica Televid 65 and 82
models (HD +APO) first-choice products.
