When Carl Zeiss created the Distagon® T* 2.8/50 FE lens the target was neither to keep it as compact as the Distagon T* 4/50 CFi lens nor to integrate a central shutter. Freed from these constraints the result is an extraordinary wide angle lens: twice as fast as usual in medium format, superb performance with excellent color correction, even wide open and close-up due to "floating elements" (FLE) that automatically adjust internal optical air spaces to the needs of close-up imaging.
This is the ideal wide angle lens for all photographers who need to produce professional results in cramped surroundings, under low light conditions and terrible time pressure. Optics conoisseurs also do appreciate the Distagon T* 2.8/50 FE lens highly. No wonder it became a preferred lens in NASA space missions.
