Review (Summary): "One of only two lenses that contains both refractive and diffractive glass elements, this image-stabilized tele zoom is dramatically more compact - and expensive ($1,143, street) - than its refractive-only Canon ($549, street) or Nikon ($479, street) counterparts. ...
... Willing to pay to travel light and save space? You won't be disappointed with this remarkably bulk-free, satisfyingly sharp, full-frame, stabilized tele zoom."
