17-50mm, the world's first lens covers from ultra wide-angle through to the standard rangeThe 17-50mm F/4 Di Iii Vxd (Model A068) covers a versatile zoom range from ultra-wide through standard focal lengths-no need to switch lenses. From landscapes containing dynamic compositions of sprawling vistas to casual snaps and portraits in the standard range, you'll be amazed by the rich variation that's possible with a single compact lens. The angle of coverage near the 50mm end closely approximates normal human vision. What's more, this zoom lens provides an F4 aperture throughout the zoom range even when you zoom in or out, making it ideal not just for still images but also video shooting. The 17-50mm F4 will dramatically expand your range of possible expression, paving the way to all-new creative photographic experiences.
