Remove the rear cap, align the lens’s attachment mark with the camera’s corresponding mark, insert the lens, and rotate it clockwise (or counter‑clockwise for Nikon) until it locks.
Set the zoom to the 28 mm position, then push the zoom‑lock switch forward; the lock indicator turns red, preventing the barrel from extending unintentionally.
