It provides freedom of creative expression and is ideal for photography indoors or in low light. HSM ensures a quiet and high speed AF as well as full-time manual focus override by rotation of the focus ring. The inner focusing system eliminates front lens rotation as well as providing high speed AF and convenient handling. The rounded 9 blade diaphragm creates a soft, attractive blur to the out of focus areas of the image. The super multi-layer coating reduces flare and ghosting and provides high contrast images throughout the lens’ focal length. This lens is equipped with a Petal-type hood to block out extraneous light and reduce internal reflections.
