TWICE VIP Award 2016 Winner! Part of Sigma’s Global Vision line, the 18-300mm F3.5-6.3 Contemporary lens is designed for APS-C cameras (equates to a 27-450mm) and features a 16.6x zoom ratio, covering focal lengths from wide to telephoto and has a 1:3 macro ratio. To compensate for any unnecessary camera shaking or movement, it includes an enhanced optical stabilizer with an optimized hyper-sonic motor for quiet and fast autofocus. Its four FLD (performance equal to fluorite) components and one SLD glass element capture sharp and contrasted images through the full focal length. Its top-quality glass is designed to ensure outstanding images in every situation. As a member of Sigma’s Global Vision line, the 18-300 lens is tested, analyzed and approved before leaving the Sigma factory, the company said. It is available in Sigma, Canon, Nikon, Sony or Pentax mounts.
