The new Barr & Stroud Sierra range of binoculars are a blend of superb
optical quality and rugged refinement that has produced an elegant range
of binoculars that take the Barr & Stroud brand to new level of
performance and sophistication.
The Barr & Stroud Sierra is the optimum all rounder in the range. Its
42mm objective lenses in combination with its magnification makes this
the model which passes the most amount of light through to the users
eyes, this is important if the observer will be using the binoculars in
low light conditions such as dawn and dusk when wildlife are on the
move, or looking closely at a bird’s plumage in dense foliage where the
light is restricted. 8x magnification is also relatively easy to hold
steady without the need for additional support, such as a tripod,
monopod or hide-clamp, in most conditions.
The Sierra range from Barr & Stroud feature rugged construction combined
with brilliant optics. They are waterproof to a depth 1.5m of water for
three minutes, plenty of time to retrieve them if you have dropped them
in a stream or puddle. This requires a high degree of mechanical quality
in the construction of the binocular which is evident as soon as you
pick the binocular up or use the super smooth focus control wheel. We
don’t expect that you will make a habit of dropping the binoculars into
deep water but we do expect that you will want to use them in any
weather the planet can throw at you, so you can feel assured that the
Barr & Stroud ‘Sierra’ can take it, again and again. This ability is
further enhanced by the binoculars’ rubber armoured body which protects
it from shocks and knocks.
The binoculars are filled with nitrogen gas which keeps water out and
also stops the optics suffering from internal fogging in adverse weather
conditions, this binocular is truly weatherproof.
Fully Multi Coated optics are standard features of the Barr & Stroud
‘Sierra’ range as are BaK-4 phase coated prisms. This degree of
sophistication ensures that as much light as possible is transmitted
through the optics which results in a super bright contrast rich images
of high colour fidelity for the user even in low light conditions where
less expensive optics and coatings result in a dramatic loss of
For the comfort of the user the binoculars are supplied with metal twist
up eyecups that are rubber coated which make them equally practical for
people to use with or without spectacles. The rapid focus mechanism
takes the user from close focus to infinity in less than one turn of the
focus control knob, which ensures that you can follow the action however
fast it is happening.
