The Carl Zeiss Sonnar 135mm f/2.8 HFT is a fast telephoto prime lens for 35 mm SLR Rollei SL35 cameras.
It is equipped with a retractable hood.
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 lens was manufactured in limited quantities at Carl Zeiss works in Oberkochen, Germany. The exact replica of the lens - Rollei-HFT Planar 135 mm f/2.8 - was manufactured in considerably greater amounts under the license agreement at Rollei works in Germany and Singapore, but it has a real HFT coating. The lens has no uncoated versions.
The lens produces a very beautiful images and is the best and most popular 135 mm lens for Rollei cameras. It is admittedly one of the best 135 mm lens ever produced.
