Crafted with precision, this lens features an advanced optical design incorporating three ED (Extra low Dispersion) glass elements and four aspherical elements, including one ED Aspherical glass element. This design ensures outstanding resolution and sharpness throughout the entire zoom range, while effectively suppressing flare, ghosting, and color bleeding for clear, detailed images. Additionally, the lens boasts a maximum aperture of F2.8, maintained consistently across the zoom range, thanks to an 11-blade aperture unit.
