Ultimate Lens for Sports & Wildlife

There are telephoto lenses and there are telephoto zoom lenses.
Then there are tele-extenders which increase the magification of a lens.
And … then there is this; three telephoto zooms in one lens.

However, it is still not available today, though originally planned for release in mid-2011.
Price tag (yet to be announced) may cause shock or heart arythmia.
