TLS Introduces Zeiss Contax Rehousing

The Zeiss Contax lenses, first introduced in the 1970s, have earned a reputation as some of the most desirable vintage optics for modern filmmakers. Designed for still photography, their renowned T* coatings and sophisticated optical design have garnered a loyal following among those seeking a distinct, organic image quality. Often referred to as the “full-frame Super Speeds,” these lenses marry pleasing sharpness with a unique character that sets them apart from today’s clinical modern glass. Now, with a new rehousing by True Lens Services (TLS), these legendary lenses are ready to take their place in the world of professional cinema.

A New Lease on Life

For years, Duclos Lenses has supported the Contax resurgence through our Cine-Mod services, converting countless sets of these lenses for filmmakers. By de-clicking the aperture, adding standardized front diameters, and installing focus gears, and converting to more modern mounts , we helped filmmakers unlock their full potential. However, this latest rehousing from TLS takes the Contax primes to a whole new level, transforming them into fully fledged cinema lenses with industry-standard build quality and features.

TLS, known for their robust cam-driven focus systems, has applied their trademark precision and reliability to the Contax primes. Their rehousing not only ensures durability but also enhances the user experience, providing smooth, repeatable operation that cinematographers can rely on. Here’s an overview of the specific focal length and versions that TLS will be offering the rehousing for:

Focal Length	Maximum Aperture	Version
15mm	f3.5	AE
18mm	f4.0	AE/MM
21mm	f2.8	MM
25mm	f2.8	AE/MM
28mm	f2.0	AE/MM
35mm	f1.4	AE/MM
45mm	f2.8	MM
50mm	f1.4	AE/MM
60mm	f2.8	AE
85mm	f1.4	AE/MM
100mm	f2.0	AE/MM
135mm	f2.0	AE/MM
180mm	f2.8	AE/MM

Features Designed for Cinematic Excellence

The TLS rehousing of the Contax primes is more than just a facelift. Each lens in the set has been meticulously converted into a cinema-ready tool while preserving the optical character that makes them so beloved. Key features include:

• Stainless Steel PL Mount: An industry standard PL mount which can easily be adapted to a wide range of other mount systems including LPL.
• 300 Degrees of Focus Rotation: Smooth, precise focus pulls with TLS’s proven cam-driven system.
• Circular Iris or ‘Ninja Star’ Option: Filmmakers can choose between a traditional circular iris for clean bokeh or a unique, visually interesting “Ninja Star” effect that the Contax Primes are known for.
• Unified 95mm Front Diameter: A streamlined and manageable size, compatible with standard matte boxes and filters—a notable departure from TLS’s typically larger front diameters.
• Non-Telescoping Design: Maintains balance and ensures compatibility with lens accessories.
• Consistent Gear Positions: Focus and iris gears are aligned across the set, making lens swaps on set faster and more efficient.

A Vintage Lens Set Ready for Full-Frame Cinema

Covering a broad range of focal lengths from 15mm to 180mm, the Contax primes provide full-frame coverage with the legendary Zeiss look. Each lens in the set has been optically aligned by TLS, ensuring that its original character shines through, whether you’re capturing subtle skin tones or rich, dimensional landscapes. The T* coatings remain a standout feature, delivering beautiful contrast and natural color rendering. Combined with their organic sharpness and creamy bokeh, the Contax primes produce an image that feels alive—far from the sterile precision of many modern lenses. Scheduled for delivery starting in January 2025, the TLS Contax rehousing meets the growing demand for vintage optics in modern production.

Final Thoughts

The Zeiss Contax primes have long been valued for their distinctive optical character and adaptability. With the TLS rehousing, these lenses gain the mechanical precision and durability needed for demanding cinema use, while retaining the vintage qualities that make them unique. For cinematographers seeking a balance between classic aesthetics and practical functionality, the rehoused Contax primes are a noteworthy option to consider.
