Highlights

• Two aspherical and two extra-low dispersion elements are incorporated within the design to minimize chromatic, spherical, and axial aberrations as well as distortions for consistent edge-to-edge sharpness and illumination
• Nano-GI coating has also been applied to alter the refractive index between elements and suppress flare and ghosting
• Features a weather-resistant design with nine different seals in eight different areas to prevent moisture and dust from entering the lens
• Quick and smooth autofocus motor helps to deftly acquire focus in less than a second
• Nine rounded diaphragm blades contribute to a pleasing out-of-focus quality to benefit the use of shallow depth of field techniques
