Please note: This lens features a KAF4 lens mount compatible with an electromagnetic diaphragm control system. In order to use this lens, the cameras firmware must be upgraded to the latest version (except for the Pentax K-70). If this lens is mounted on a camera without proper firmware upgrade, its diaphragm control mechanism becomes inactive, making it impossible to obtain correct exposure. Cameras which are compatible with this system: Pentax K-70, K-1, K-3 II, K-S2 and K-S1.
