Not a zoom, this lens offers three discrete focal lengths that each click-stop into place. Among its other unusual amenities: red barrel threading that alerts you to screw on the hood.
What looks like a zoom, is used like a zoom, but isn't a zoom? Leica's 16- 18-21mm f/4 Tri-Elmar-M ($3,495, street). With three individual focal lengths in a single housing, and no intermediate settings, this 21-24-28mm equivalent (on the M8 digital) doesn't zoom, but click-stops through its focal lengths.
