Kenko Ultraview 10 x 25 WP Binoculars: £59.99

High quality compact binoculars

Polycarbonate-The main advantage of polycarbonate over other types of plastic is unbeatable strength combined with light weight
ECO Glass-Glass refining takes place without arsenic, antimony or other harmful heavy metals.
Phase Coating - This is a special treatment for roof prism binoculars that results in higher resolution and clarity. For bird and butterfly watchers, phase coating enhances colour resolution and close focus detail.
JIS Class 6 -Protected against powerful water jets, Water projected in powerful jets against the enclosure from any direction shall have no harmful effects.
Summary of test conditions for Class 6: Test means: Water jet hose nozzle Figure 6. Nozzle 12.5mm diameter, distance 2.5m to 3m. Water flow rate: 100 litres per minute +/- 5%. Duration of test: 1 min/m2 at least 3 min.

Eye Relief - This is the distance from the eyepiece to where your eye sees the full field of view.
Eyeglass wearers need the longest eye relief because their glasses limit how close they can get to the eyepiece. Eyecups also play a role in how close you can get to the eyepieces. Especially if you're an eyeglass wearer, you will be amazed at the improvement in viewing when using long eye relief binoculars.
Lens Coatings - Every lens surface has the potential to reflect rather than capture light.
Lens
coatings reduce or eliminate reflections and increase light capturing capability. Nowadays, most binoculars have some sort of lens coatings applied... but there are varying degrees of coverage. "Multi-" coating means that multiple layers of coatings have been used to give enhanced anti-reflective affects. "Fully" multi-coating means that all lens surfaces have been multi-coated... the most desirable degree of anti-reflective lens coating for binoculars.

Porro vs. Roof Prism - The old fashioned style of binoculars where the eyepieces are not lined up with the objective lenses are called "Porro" prism. The new in-line style of binoculars is called "Roof Prism". There are advantages to each. The Porro Prism style is less expensive to achieve top optical clarity and brightness. However, Roof Prism binoculars can now match this when they have "phase coatings". Porro will also have better stereoscopic depth perception due to the wider apart objective lenses. Roof Prism Brightness - is simply the square of the exit pupil. Exit pupil - is simply the size of the objective lens of the binocular divided by the magnification. i.e. 7x50 = 50 divide by 7 gives an exit pupil of 7.1 BaK4 and BaK7 Prisms - These refer to "Barium Crown Prisms" which are a premium type of Binocular prism that enhances light and image capturing capability. BaK7 is good... But, BaK4 is best due to its outstanding refraction index. The BaK4 glass prism is famous for its perfectly round exit pupil and clear, unvignetted image.
