The Carl Zeiss Planar 50 mm f/ 1.4 HFT is an ultra fast multicoated prime lens. The lens was manufactured in a small lot for Rollei SL35 cameras at Carl Zeiss works in Oberkochen, Germany. The lens was designed by great Erhard Glatzel. According to the manufacturer, these lenses feature a proprietary T* coating, but are marked as HFT (co-designed by Carl Zeiss and Rollei) due to marketing consideration. The exact replica of the lens - Rollei-HFT Planar 50 mm f/1.4- was manufactured under the license agreement at Rollei works in Germany and Singapore, but it has a real HFT coating.
