Opticron Spotting Scopes : ES 80 GA ED Mk II

Opticron ES80 GA ED Mk II

The ES 80 GA ED/45 advances the tradition of quality and value begun with the MKI ED with a new multi-coating system integrated into an all-new magnesium polycarbonate and aluminium body. Now 100% nitrogen waterproof, the fully rubber armoured body houses a high-grade ED (extra low dispersion glass) element within the objective lens system that virtually eliminates the distorting effects of chromatic aberration at magnifications over 35x. As a result, images are vibrant and 'true to life' and what's more - reproduced consistently across the magnification range..

The advantages of ED
By using an ED or 'extra low dispersion' glass element in the primary objective system, these fieldscopes provide a higher degree of colour correction when compared to conventional glass objectives. More apparent at higher magnifications and under certain light conditions (e.g. when looking over water on a bright warm day) the image appears sharper and colours remain truer to life across the magnification range.
The ability to bring into clear and sharp focus indistinct objects such as coloured identification rings or shades of plumage in poor light over long distances are the hallmarks of an HR ED fieldscope. This extra optical clarity combined with all the features and exceptional build quality make them the definitive choice for the professional ornithologist.

SDL eyepiece:
A 5-group 8-element 'super' zoom, the 40935 SDL has been designed to maximise the performance gains inherent in Opticron ED objective lens fieldscopes at higher magnifications. Offering an optimum ratio between field of view and resolution, the main viewing characteristics of the SDL eyepiece are superior cross-field definition at all magnifications coupled with exceptional viewing comfort. Mechanically the eyepiece is waterproof, uses the M41.5 collar thread attachment, features a 90 degree rotation between high and low magnification settings plus a rotating eyecup that can be positioned to match individual needs. Supplied in soft padded case.

HDF eyepieces:
The preferred choice for quality and viewing comfort, HDF eyepieces have large dia. eyelenses and provide 'walk-in' field of vision. All eyepieces feature long eyerelief for full field of view with or without spectacles and fixed magnification models are wide angle.

HR eyepieces:
Good choice eyepiece for the value conscious requiring long eyerelief, as all eyepieces offer full field of view with spectacles.
