The FA J lenses combine simple functionality and design in a lightweight body.

Iris control is performed on the camera. A new type of plastic aspherical lens is used for the fourth lens for providing sharp imaging performance in a compact, lightweight body weighing only 180g. The zoom has an easy-to-use focal length range and is even capable of taking closeups at a minimum shooting distance of 40cm. This is an easily deployable lens suitable for everyday shooting, including snapshots using the programmed automatic exposure.
