Two FLD elements and one SLD element have been incorporated within the lens design to correct for chromatic aberrations throughout the entire focusing range and to ensure high image sharpness, clarity, and contrast. Additionally, four aspherical elements have been integrated into the lens's construction to eliminate distortion and suppress sagittal coma flare significantly, making this lens an ideal choice for astrophotography and nightscapes.
