This Macro 10x Lens performed exceptionally well in all areas. The images captured are detailed and sharp, with minimal softening around the edges. The results are genuinely mesmerizing - especially in trying to decipher what the subject actually is, having been captured so closely and at an unusual angle. BaK4 prism glass is made from Barium Crown glass and is used for better light transmission on binocular lenses, helping refract light and reduce reflection too with multi-coated optics. When possible you should always look for this glass on binoculars as they improve the image seen dramatically through the lens.
