It is Leica's longest, biggest, and heaviest telephoto lens. It was delivered in 2006 on special order from a rich photography aficionado, Sheikh Saud Bin Mohammed Al-Thani of Qatar, at a price of 16 million Hong Kong Dollars - the equivalent of 2,064,500 US dollars. The lens is a unique copy, but a prototype is on display at Leica's factory showroom in Solms, Germany, and can be admired there. Unfortunately, little is known about the technical specifications of the lens. It has a bayonet mount for Leica's R-series manual focus SLR-cameras, is approximately 1.2m long (1.55m with lens hood attached), has a maximum lens barrel diameter of about 42cm, and weighs no less than 60kg. With a focal length of 1600mm, it covers a diagonal angle of view of merely 1.5 degrees. The lens should be compatible with Leica's 1.4x and 2x APO-teleconverters, giving rise to whopping 1:8/2240mm and 1:11/3200mm optical systems, respectively.
