TLS Zeiss B Speed
The Zeiss B Speeds or Super Speed MK1 as they are sometimes known, were released in the mid 70’s and were some of the fastest lenses around at this time. The range consists of 18mm, 25mm, 35mm, 50mm and 85mm with a T stop of 1.4. One thing that makes the B Speeds stand out is the triangular iris which results in that distinctive triangular bokeh. This is something DOPs either love or hate and consequently, we can offer Zeiss B Speed rehousing with the option of a triangular iris, or a new circular iris design.
These lenses are also known for being very compact and as a result, TLS is rehousing the lens into a 95mm front, whilst keeping the cam-form system, high quality and strength. The original movements of the elements, some of which are floating, will be incorporated into the design so there is no loss of quality to the image.
Dual Cam System
The 18mm, 25mm and 35mm B Speed lenses have a dual cam system to cover the floating element movement.
The Upgrade Process:
New stainless steel PL mount
High-grade aluminium and stainless steel body construction
New can form focus drive
High calibre focus and iris rings
Engraved dual focus scales
Standard 95mm front ring
The Results:
The build quality of all our re-engineered lenses is extremely high. We ensure all our modified units are highly robust and will last for many years to come.
The optics of the B Speeds will remain unchanged and their unmistakable visuals will be preserved as they originally are.
The updated units are compatible with electronic drives, follow focus units and matte boxes. Focus pullers will appreciate the smooth feel and reliable movement that provides excellent results every time.
