introduced its HJ14ex4.2 portable HD lens. Alan Lewis, Canon marketing manager, said that the lens "is the product of the show for us." The lens features a focal length of 4.3mm and angular field of view of 96.3° (2/3, 16:9) at wide end. It also offers a 14X zoom ratio reaching to 60mm (120mm with extender), which greatly expands the video expression.
The lens uses the latest 3-D design technology and large aspherical elements, which creates a unique optical layout. It maintains high resolution from the center to each corner of the picture. Moreover, by adopting a new coating technology and the new simulation system, the focus breathing has been diminished and the light quantity of the picture corners has been maintained. The HJ14ex4.2 also features an ultimately minimized color aberration, ghosting and picture distortion.
