Its optical system features a three-element construction made from high-quality FCD-1 ED glass by Hoya (Japan) and incorporates two air gaps. This design delivers a corrector that significantly outperforms the typical two-element ED apochromats found in this price range. With a calculated polystrehl value exceeding 0.9, it provides much sharper and clearer images compared to the 0.8 achievable with two-lens systems.
