This lens represents several "firsts" for Pentax. It is the first Pentax lens to feature Super ED glass for improved chromatic aberration suppression and Aero Bright II nano-coating to minimize flare. The D FA* 70–200mm lens is also one of the first two Pentax lenses to feature an improved implementation of the Quick-Shift Focus System (full-time manual focus), with QFS/A and QFS/M positions on the autofocus switch. In QFS/A mode, the lens will not allow manual focus during autofocus operation until focusing is complete. In QFS/M mode, autofocus will stop and switch to manual focus immediately as soon as the focus ring is turned.
