Body
This full-size binocular weighs 260g.
Aspherical lens elements help to ensure that the light passing through the various areas of the lens all focuses on the same point, ensuring sharper imaging.
Porro prism designs have the lens barrels set further apart than the eyepieces making them larger in size and bulkier than their equivalent roof prism models. The simpler optical manufacturing process makes it less expensive to produce equivalent porro prisms over roof prisms. They also do not suffer from phase distortion – which affects contrast and sharpness on roof models (which needs phase coatings to solve) and they produce slightly better depth perception because the lens barrels are set slightly further apart than the eyepieces.
Coating Rating
Coatings help improve light transmission, especially in roof prism designs. This binocular is rated as MULTI-COATED, meaning that at least one surface has more than one coating on it.
Special Coatings
None
Eye Relief
