SPECIFICATIONS:

Fast maximum aperture telephoto lens optimized for digital SLR cameras. This telephoto lens has a fast maximum aperture, and also features a new super multi-layer coating, which optimizes the characteristics of digital SLR cameras.

• ELD Glass
  A versatile, fast aperture telephoto lens for both digital and film SLR cameras. Two ELD glass elements reduce chromatic aberration to a minimum and also ensure sharp, quality images of high contrast.
• Multi Layer Coating
  The new multi-layer lens coating reduces flare and ghosting, a common problem with digital SLR cameras.
• Internal Focusing
  The Internal Focus system ensures the overall length of the lens does not change during focusing, ensuring convenient handling and ease of use.
• HSM System
  The HSM (Hyper Sonic Motor) models provide fast, silent AF function as well as full- time manual focus override.
• Rear Filter
  A drop-in 46mm filter holder in the rear part of the lens barrel can be rotated to facilitate the use of filters, including a polarising filter, in situ.
• Optional EX Teleconverters
  Simply adding an APO teleconverter (optional extra), means that this lens can be used as a 420mm F4 AF ultra-telephoto lens with a 1.4X EX teleconverter, or a 600mm F5.6 AF ultra-telephoto lens with a 2X teleconverter.
