Zeiss Apo Sonnar T* 1700 mm F4 lens
Designed to be used with a Hasselblad 6x6 medium format camera this monster lens weighs in at 256 KG (564 lb) and uses unique methods for handling focusing (because of the weight of each glass element). This lens becomes the largest telephoto lens for non-military use anywhere in the world. The price hasn't been disclosed (although we've heard rumours) nor has the private owner, although some of the text on the lens is in Arabic and it carries a 'State of Qatar' emblem.
Some of the resulting lens blanks weighed more than 25 kg (55 lbs.) and were valued more than a luxury sedan!
The resulting Carl Zeiss Apo Sonnar T* 4/1700 lens consists of 15 optical elements in 13 groups. It is the largest telephoto lens ever produced for civilian photographic purposes and a testament to the precision design and manufacturing capabilities at Carl Zeiss.
