Thanks to impressive precision, low weight and a robust design, the ZEISS Conquest Gavia is a companion you'll always want when making discoveries off the beaten path. To observe the natural world without causing a disruption, you need the right equipment: the new Conquest Gavia 85 spotting scope from ZEISS is the ideal travel companion thanks to its compact design and low weight, so you can capture all the wonders of nature from just the right angle. The high-resolution lens system and rapid focus transform the shots into unforgettable images. Whether youвЂre taking photos of individual birds or entire flocks, the 60 ? magnification of the Conquest Gavia 85 enables nature observers to enjoy nature to the max, ensuring that no detail goes unnoticed. The universal tripod plate is compatible with a range of tripods. The new ZEISS Conquest Gavia provides birdwatchers and nature observers with a high-performance spotting scope that is simply great value. Extensive digiscoping accessories go one step further in expanding the wide range of uses.

The new ZEISS Conquest Gavia 85 spotting scope with angled view was specially developed to meet the needs of wildlife and nature observers. Its compact design and low weight make this spotting scope with its large 85 mm lens diameter ideal thanks to the high optical performance and brightness it delivers, even in remote locations. “Its 60x magnification and wide-angle field of view mean that tricky identification tasks are no problem even from a great distance thanks to highly detailed image rendition. With the close near-focus setting, which is unique in its class, observing smaller objects such as songbirds or butterflies becomes a very special experience,” explains Dr. Gerold Dobler, Product Manager at Carl Zeiss Sports Optics GmbH. “What’s more, the intuitive and dynamic focusing mechanism enables fast and smooth focusing during observation.”
“With the new ZEISS Conquest Gavia 85, birdwatchers and nature observers receive a high-performance spotting scope that is simply a great value,” says Dobler.
A universal tripod base makes it very easy to integrate the spotting scope into the quick-change system of the Manfrotto tripod heads. Extensive digiscoping accessories expand the wide range of uses, and it is very easy to connect an astronomical eyepiece. “All observers can quickly and easily set the particular magnification and field of view that match their individual needs,” continues Dobler.
Each optical surface loses a portion of passing light due to surface reflections. Normally each lens wastes between 4 and 8 per cent of light, but in complex devices with multiple lenses the total loss of light can be higher than 50%. To counter this, Zeiss engineer Alexander Smakula started covering lenses with microscopic layers of anti-reflective materials. The patent was registered in 1935. Binoculars and riflescopes with this "Transmission layer" were from that point, given the designation "T", and the improved multi-layer coating developed at the end of the '70s was named "T*". The process involves the vapor deposition in a high vacuum of layers of material, with each layer adding approx. 1/10,000 mm.
Carl Zeiss has developed a coating for the lenses of binoculars and riflescopes that gives you clear and unrestricted visibility whatever the weather. You know how irritating it is when raindrops land on the lens in bad weather and impair your visibility.
We took as our example the leaves of the lotus plant with their water-resistant (hydrophobic) qualities and added a multi-layer protective coating (LotuTec coating) on the external lenses of many ZEISS devices. This ensures that water rolls off the glass straight away without leaving any residue and that dirt and fingerprints do not stick to the lens.
The Carl Zeiss LotuTec coating has no effect on either the light transmission or the scratch resistance. On the contrary: you will find the extremely smooth surface of the lenses on your valuable binoculars even quicker and easier to clean.
When hunting, it is a definite advantage to have high-contrast images with clearly defined structures. Carl Zeiss has therefore fitted all ZEISS roof prism binoculars with the "P-coating", guaranteeing maximum image sharpness.
Almost all high-quality, modern binoculars are "roof prism binoculars". Compared to the wide "Porro" lenses, they are very sleek in design, and both the incoming and outgoing light rays show little, if any, misalignment. The "space-saving" nature of the design is achieved through ensuring that the incoming light is divided into two bundles, and that both sides of the roof are used twice as reflective surfaces. The precision of these two flat surfaces, the common edge and the 90° angle between them are all hugely significant.
For resolution with maximum detail both roof surfaces are also treated with a special coating. This so-called "phase correction coating" prevents wave-like optical effects ("phase shifts") and therefore ensures full clarity.
Carl Zeiss opened his optics workshop in Jena in 1846. By 1861 Zeiss was counted among the best scientific-instrument makers in Germany and by 1866 had sold the company's 1000th microscope. In 1872, together with physicist Ernst Abbe and chemist Otto Schott, they designed greatly improved lenses. Later the company was incorporated as Carl-Zeiss-Stiftung or Carl Zeiss Foundation and has been pioneering in almost all optics-related spheres ever since.
