For decades, Zeiss Super Speeds have earned a legendary status among cinematographers for their signature look, fast apertures, and timeless character. With age comes a decision: continue maintaining vintage mechanical systems or invest in a long-term rehousing solution?
The Challenge of Vintage Optics
While the optical performance of Zeiss Super Speeds remains as relevant today as ever, the mechanical components tell a different story. Owners often face:
- Recurring service costs due to outdated mechanical designs.
- Longer turnaround times for repairs as original parts become harder to source.
- Increased risk of mechanical failure during shoots, jeopardizing productions.
- Reduced confidence in long-term reliability and rental readiness.
Known Issues with Original Multi-Thread Focus Systems:
- Complicated helicoid mechanisms result in higher service costs and complexity.
- Inconsistent focus movement—any added weight on the lens front worsens focus binding.
- Image shift and backlash caused by thread play during focus pulls.
- Unfriendly gearing and front diameters for modern follow focus and matte box setups.
- Focus scale slip and maintenance challenges that only grow with time.
Rehousing as a Future-Proof Investment
Rehousing Zeiss Super Speeds addresses all these concerns— preserving their signature cinematic image while replacing worn mechanical components with a precision-engineered, modern build.
Key Rehousing Features:
- Original Zeiss optics retained, preserving their vintage image character.
- Non-linear focus cam system — providing a greater spread of focal distances across the focus scale.
- Precision mechanical rebuilds for smooth, reliable operation.
- Optional circular iris upgrade for consistent, creamy bokeh at any stop.
- Consistent front diameters and gear positions across the set.
- Enhanced compatibility with gimbals, drones, matte boxes, and focus systems.
- Ease of servicing by in-house technicians.
Benefits at a Glance:
- Reduced service time and cost.
- Long-term savings — lower total cost of ownership in under 1 year.
- Improved reliability and fewer mechanical failures on set.
- Superior focus throw with consistent, accurate scaling—ideal for 1st ACs.
- Higher resale and rental value.
- Peace of mind with a new 3-year warranty.*
