Zeiss Super Speed TLS MKI B-Speed T1.4
Equipment description
The first and oldest generation of lenses dedicated to the Super 35, it features a unique 9-blade aperture design that produces a triangular bokeh effect when closed.
A fully open lens will behave like any other in the Super Speed series, but a closed one allows for a more subtle focus rolloff.
Made by UK-based True Lens Services rehouse, it allows the use of focus and clipon motors.
You can see the exceptional results in the photos.
Below is a list of films that used B-Speed lenses:
Cab Driver (1976), Midnight Express (1978), Raging Bull (1980) and The Shining (1980).
