Feature Highlights The revolutionary new 28-200mm zoom from the company who started it all in 1992. This highly innovative lens combines Hybrid Aspherical elements and Low Dispersion (LD) Glass for a unique optical pattern that provides ultimate contrast, true color and reduced distortion from wide to tele. Add to it our sophisticated injection molded barrel and Triple-Cam Zoom combined with our Internal Focusing Mechanism, and you've got the closest focusing lens of its kind (down to an amazing 20.5" at 135mm) in one compact and lightweight zoom.

Sharpness is poor. My wife's point and shoot cameras provide better resolution, so that I'm embarrassed to be carrying around my big $1200 camera, and her prints look sharper. The lens extends by gravity when hanging down from a shoulder strap. Autofocusing is sometimes delayed. It gives a great range of focal lengths for the money but results are frustrating. OK for family snapshots.
