It's equipped with 10 aperture blades for micro-contrast control and low chromatic aberration, with a T1.9 to T22 aperture range and an 80mm front diameter. The focus ring is rotatable up to 300° and the lens markings are fluorescent and displayed in both feet and meters. With a 40.1° horizontal angle of view and 46mm image circle, this lens will help you capture every detail. Color matched throughout the set, the Athena Primes are sure to punch well above their weight!
