What We Do

Six Ways We
Serve the Image

From full PL-mount rehousings to precision servicing and bespoke manufacturing — every project handled by highly skilled technicians with decades of industry expertise.

01
Lens Rehousing

Vintage optics rebuilt into precision cinema housings. High-grade aluminium and stainless-steel bodies eliminate mechanical backlash, with extended focus throw and standardised gear positions for lens control systems.

PL / LPLEFT0.95–T4.510–228mm
02
Repair & Servicing

Standard service or full restoration for broadcast, professional and cine lenses — prime and zoom. Completed to manufacturer specifications using correct lubricants, cleaning agents and locking compounds.

Cine-Mod Conversion

A cinematic modification that bridges vintage glass and modern production workflows. Vintage lenses gain the mechanical and optical characteristics required for professional cinematography.

Industry StandardProduction Ready
04
Lens Evaluation

Expert consultancy for buyers considering a vintage lens purchase. TLS technicians assess condition, performance, and suitability — independent guidance before you invest.

The Process

How a Vintage Lens
Becomes a Cinema Tool

Step 01

Mount Conversion

Original mount replaced with PL or LPL. Back focus adjusted via standard shims. Compatible with ARRI, RED, Sony VENICE.

Step 02

Precision Housing

New barrel machined from high-grade aluminium and stainless steel. Eliminates mechanical backlash and image shift.

Step 03

Extended Focus Throw

Helicoid rebuilt with extended focus throw for precise focus pulling. Standardised gear positions for lens control systems.

Step 04

Iris & T-Stop Calibration

Aperture rebuilt with smooth, continuous iris adjustment. Calibrated to accurate T-stops. Consistent across the TLS range.

Step 01

Mount Conversion

The original mount is removed and replaced with a PL or LPL mount, making the lens compatible with modern cinema cameras — ARRI, RED, Sony VENICE, and beyond. Back focus is precisely adjusted via standard shims.

Step 02

Precision Housing

A new barrel is machined from high-grade aluminium and stainless steel. The vintage housing is replaced entirely, eliminating mechanical backlash and image shift that plagued the original design.

Step 03

Extended Focus Throw

The focus helicoid is rebuilt with an extended focus throw — critical for precise manual focus pulling on professional productions. Common focus and iris gear positions match lens control system standards.

Step 04

Iris & T-Stop Calibration

The aperture is rebuilt with smooth, continuous iris adjustment and calibrated to accurate T-stops. Front diameters range from 95mm to 143mm with M105 or M120 filter threads — consistent across the TLS range.
