Hawke Sapphire ED 8x42 Details

These 8x42 binoculars with their first rate components and extremely high quality optics are ideal for the more serious birder or wildlife observer who demands a high level of performance in all areas. Available in either black or green, the rubber armour exterior protects the optics as well as adding grip and making them more comfortable to hold.
These 8x binoculars provide a good level of magnification that is ideal for close to mid level distances, whilst also making it relatively straightforward to keep the image steady in your hands so that you can enjoy a shake-free image and thus more easily study every minute detail.
Along with an excellent optical design, the moderate power also helps produce the extremely wide and class-leading field of view (142 m @ 1000 m) that you are presented with when looking through this 8x42 Sapphire ED. This offers many advantages, but is particularly important to users like birders operating at reasonably close ranges as it makes it much easier to quickly locate and then follow small, erratic, fast moving birds.
The 42mm objective lenses are large enough to enable them to capture enough light for the binocular to perform well in most lighting conditions, be that from an early morning until sunset. But at the same time they are not so large as to make the instrument too bulky and thus difficult to carry about in the field.
With a close focus distance of 2 meters, these would not make the ideal option as a dedicated butterfly binocular, but it is more than acceptable for the occasional observation of these and other insects from close range.
The 18mm of eye relief is excellent. This in conjunction with the adjustable click-stop eye cups makes this model a great option for anyone who wears glasses whilst binning.

About Hawke Sapphire ED Binoculars

Award winning Hawke Sapphire ED binoculars offer great optical performance using the best technology and great build materials that makes them incredibly durable. You can choose between pocket and all-round models for everyday use. They integrate ED glass, are fully multi-coated and hydrophobic coating included in objective lenses. Sapphire ED binoculars can also pride themselves in wider field of view and long eye relief. Made out of magnesium housing and enclosed in beautifully designed rubber armouring makes them a real pleasure to use. They come in black and green color. The comfortability is also integrated in models with 43 mm lens diameter with an open-bridge design offering a firm wrap-around grip. They are well protected against water and internal fogging and therefore able to offer the maximum resilience in extreme weather conditions.

Basic Features

Great ergonomics integrated in Hawke Sapphire is shown in a lightweight and compact roof prism design that offers straight through design for comfortable handling. The models offer top-hinge design with 43 mm models and open-bridge design with 43 mm models for additional reduction of the weight and available surface to hold them firmly. Sapphire ED binoculars use magnesium alloy which is extremely lightweight for everyday use, but still durable to withstand the test of time. Underside of the barrels lie thumb depressors that help you with correct position of your hands, giving you a great balance. The rubber armouring also protect the whole body of these binoculars against impacts. Sapphire ED models are tightly sealed to make them resilient in even the most extreme weather conditions. Together with nitrogen gas filling to prevent internal fogginess, this significantly prevents corrosion and molding in a long run.

Optical Properties

Sapphire ED offers incredible optical performance at a reasonable price for everyday use of birdwatchers and other wildlife observations and will satisfy even hunters and other more professional users. All the models offer amazing wide field of view that can easily help you in dynamic situations when you have to track down fast moving subjects such as big birds. They are fully multi-coated, with phase correction, dielectric prism coatings and extra-low dispersion glass that helps to eliminate unwanted chromatic aberration and glaring. This technology also helps with better light gathering and enhances contrast and colors for extremely lifelike images. There is also hydrophobic objective lens coating added, which is scratch-resistant since it repels moisture. When it comes to focusing, the Sapphire ED binoculars use grippy central focusing mechanism for quick adjustments and right-eye diopter to compensate for differences in the eyesight. Multi-positioned eyecups are also very convenient for quick and firm twist-up adjustments to make a proper eye-relief.


The Sapphire ED comes in high-quality leather case, impressively designed and well-padded to protect them. There is also neoprene neck strap added, objective lens covers and rainguards.
