SA205 8x42 ED Flat-field Binoculars With BaK-4 Prism IP67 Waterproof

Flat Field Correction

The flat-field design can effectively control the edge distortion of the field of view, making your field of vision clear.

42mm Objective Lens

The large objective lens can gather more light to provide more clear image and increase your field of view range.

ED Glass

ED glass can eliminates chromatic aberration or color fringing, a visual defect common in binoculars. You'll enjoy razor-sharp images.

FMC Coating

It improves light transmittance; reduce light loss; allowing you to obtain clearer and brighter images and provide a better observation experience.

The view through the SA205 8x42 is excellent: it’s razor sharp across the entire field. Off-axis aberrations such as pincushion distortion are very mild. Field curvature is essentially absent. Contrast is excellent, with a very neutral colour tone. Colour correction is also markedly improved over the SV202 series. The centre of the field is essentially devoid of secondary spectrum. Glare  suppression is exemplary. Glassing strongly backlit scenes with the SA205 stubbornly refuses to throw up glare. In addition, you could detect no glare when aiming the instrument at a bright sky after sunset. 

Large Anti-slip Focusing Wheel

The smooth focusing handwheel ensures accurate and stable focusing with one hand; fast focus and easy to operate. The metal focus wheel is deeply knurled and is easy to engage with. It rotates very smoothly with no free play in either direction. 1.5 revolutions anticlockwise brings you from one end of its focus travel to the other. It’s highly responsive, requiring only a light touch to dial up the best views. 

Right Visual Diopter Adjustment

Adjust visual balance for easier observation and convenient for people with myopia or presbyopia to see the effect directly without wearing glasses. The right eye dioptre on the SA205  8x42 is a real treat. Instead of just rotating smoothly, it has click stops that are very easy to adjust and keep the user's preferred position firmly.

Rubber Protective Skin

Environmental protection rubber protective skin; protects your binoculars from damage; not sticky; not greasy; give you a better using experience.

Magnesium Alloy Body

The ED binoculars is light weight and corrosion resistant; superior to other materials and long use time.

Twist-up Eyecups

The twist-up eyecups give you a comfortable experience; it allows you to customize the eye relief to obtain a full field of view with or without glasses.

IP67 Waterproof

The binoculars can also be used in bad weather; increasing the durability of the binoculars and extending its service life.
