Specification E.g. 8x42. The number ‘8’ denotes the magnification and means an object appears to be 1/8th of its’ actual distance away.

The rise in popularity of roof prism binoculars is as a direct result of this system being favoured in the development of instruments with user oriented features. These include; internal focusing for waterproofing, long eyerelief eyepieces that enable the viewer to obtain the full field of view with or without glasses and close focus making them useful for watching butterflies and other insects. B when seen on roof prism binoculars including Opticron BGA = full field of view for spectacle wearers. GA = rubber armouring and W or WA = wide angle vision. CF, (centre focusing) is more popular than IF (individual eyepiece focusing) especially when you need to focus at different distances under 50m. Most ‘IF’ binoculars are 7x magnification and have a large depth of focus which tends to eliminate the need for focusing adjustment at distances over 50m. What magnification? Within any given range of binoculars the higher the magnification relative to the objective lens diameter, the lower the apparent image quality. Images appear less sharp and have a lower ‘relative’ brightness and poorer colour contrast. Higher magnification binoculars also; a. have a shallower depth of focus (distance in focus at any one focus setting), requiring more use of the focus wheel b. amplify natural hand-shake affecting the stability of the image being viewed. For general observation choose a 7x or 8x magnification. If you want binoculars of 10x or over try them first. What objective lens size? The amount of light entering a binocular is directly related to the surface area of the objective lens (OG). A 50mm OG will admit 2.5x the light of a 30mm OG. The amount of light reaching the eye is known as the exit pupil diameter (EPD) and its’ size can be found by dividing the OG diameter by the magnification. For example the EPD of an 8x32 = 4mm while the EPD of an 8x56 = 7mm. As a general rule the iris dilates between 2 and 3 mm (bright sunlight) and 6 and 7 mm (twilight) and so a choice should be made on the type of use the binocular is being put to. For general use choose a 7x42 or 8x42 binocular with an EPD of +5mm. The field of view of a binocular is dependent on the optical design and not simply a product of the magnification and objective lens diameter. It is expressed as either the width of panoramic view in metres from a distance of 1000 metres or in degrees where 1˚ is approximately 17.45m. Wearing glasses Many binoculars provide the full field of view when wearing glasses by either folding down the rubber eyecups or by turning/pushing retractable eyecup assemblies to the ‘down’ position. As a general rule the longer the eyerelief - the distance between the surface of the eyepiece and the point where the pupil is positioned for full field of view - the better the instrument for spectacle wearers. If you think you want to wear glasses while using your binocular, choose one with an eyerelief of 15mm or over. Weight For many people, small, lightweight binoculars that can be taken anywhere will be used much more than larger, heavier ones which tend to be left at home or in the car!

CHOOSING YOUR BINOCULAR
The following information aims to give you a basic understandingof how binoculars work, the different specifications available andwhat they mean, plus some points to help you choose the bestinstrument suited to you.
Specification E.g. 8x42. The number ‘8’ denotes the magnificationand means an object appears to be 1/8th of its’ actual distanceaway. Using this rule an object 40m distant appears to be only 5maway. ‘42’ is the diameter of the objective lens (the large end) inmm through which light enters the binocular.
Z or B stand for porro prism binoculars. The basic optical designof these ‘traditional-shape’ instruments mean they tend to deliverbetter optical performance for your money compared to roofprism (D) binoculars, which are more compact but also moreexpensive.
The rise in popularity of roof prism binoculars is as a direct resultof this system being favoured in the development of instrumentswith user oriented features. These include; internal focusing forwaterproofing, long eyerelief eyepieces that enable the viewer toobtain the full field of view with or without glasses and close focusmaking them useful for watching butterflies and other insects.
B when seen on roof prism binoculars including Opticron BGA =full field of view for spectacle wearers. GA = rubber armouringand W or WA = wide angle vision. CF, (centre focusing) is morepopular than IF (individual eyepiece focusing) especially whenyou need to focus at different distances under 50m. Most ‘IF’binoculars are 7x magnification and have a large depth of focuswhich tends to eliminate the need for focusing adjustment atdistances over 50m.
What magnification? Within any given range of binoculars thehigher the magnification relative to the objective lens diameter,the lower the apparent image quality. Images appear less sharpand have a lower ‘relative’ brightness and poorer colour contrast.
Higher magnification binoculars also; a. have a shallower depth of focus (distance in focus at any one
focus setting), requiring more use of the focus wheelb. amplify natural hand-shake affecting the stability of the image
being viewed.For general observation choose a 7x or 8x magnification. If youwant binoculars of 10x or over try them first.
What objective lens size? The amount of light entering abinocular is directly related to the surface area of the objectivelens (OG). A 50mm OG will admit 2.5x the light of a 30mm OG.The amount of light reaching the eye is known as the exit pupildiameter (EPD) and its’ size can be found by dividing the OGdiameter by the magnification.

For general use choose a 7x42 or 8x42binocular with an EPD of +5mm.
The field of view of a binocular is dependent on the opticaldesign and not simply a product of the magnification andobjective lens diameter. It is expressed as either the width ofpanoramic view in metres from a distance of 1000 metres or indegrees where 1˚ is approximately 17.45m.
Wearing glasses Many binoculars provide the full field of viewwhen wearing glasses by either folding down the rubber eyecupsor by turning/pushing retractable eyecup assemblies to the‘down’ position. As a general rule the longer the eyerelief - thedistance between the surface of the eyepiece and the point wherethe pupil is positioned for full field of view - the better theinstrument for spectacle wearers. If you think you want to wearglasses while using your binocular, choose one with an eyereliefof 15mm or over.
Weight For many people, small, lightweight binoculars that canbe taken anywhere will be used much more than larger, heavierones which tend to be left at home or in the car!

Oasis is the name given to a 64 layer coating processapplied to the reflective surface of each roof prism. Oasisimproves light emission to 99% over a broader spectrum
at the reflective face when compared to silver coating traditionally usedon many high quality roof prism binoculars. The result is a measurableincrease in light transmission and overall image clarity.
PC phase correction coatingWhen light waves are reflected at the opposite faces of a roof prism,phase shift occurs resulting in marginal deterioration in sharpness. Phasecorrected coatings are designed to correct this phase shift within theprism – increasing overall clarity and definition.
The lightweight bodies are nitrogen gasfilled waterproof, and protected by aquality natural rubber armouringspecially contoured to deliver positivegrip and balance with or without gloves.

An up-rated version of the original Opticron HR, the SR.GA offersexcellent standards of optical performance and manufacturingquality in a traditional porro prism format.
Simplicity of design (the binoculars are not waterproof)coupled with the highest available grade of glasscomponents mean that all four models deliver stunningresolution – matching many roof prism binoculars costingtwice the price. In addition each model benefits from a‘combination’ multi-coating meaning different ‘coating types’are applied individually to different components within the opticalsystem. More costly than a universally applied single multi-coating,the process has an appreciable effect, improving colour contrast inbright sunlight at midday or low light at dawn and dusk.
The lightweight body is finished in a contourednatural rubber that completely covers theinstruments in a protective skin. The semi-circular rib patters deliver positive handling inall weather conditions with or without gloves.
Models 8x32 and 12.5x50 feature wide-angleeyepieces. Full field of view with glasses isobtained on the 8.5x50 and 10x50.
SR.GA binoculars are supplied with a comprehensive30 year guarantee.
The definitive variable power zoom, the SR.GA 9-22x50 is designedfor people who want maximum flexibility from a hand held binocularwithout compromising too much on optical performance.
Utilisation of a 50mm dia. objective and ‘HR’ (High Resolution) porroprism optical configuration ensures image clarity at lowermagnifications is comparable to similarly specified fixedmagnification binoculars. The instrument has long eyerelief eyepiecesfor spectacle wearers and delivers a good depth of field with anadequate field of view.
At higher magnifications image clarity is largely maintained, makingthe instrument excellent for getting in really close to the action atsporting events as well as accurate nature observation at distance.
Finished in durable rubber armouring for comfort and protection, theSR.GA Vari-power Zoom features wide wheel focusing, left sidedioptre adjustment and integral tripod adapter socket for mounting toa standard photo/video tripod. The model is supplied complete witha comprehensive 30 year guarantee.
