True Lens Services (TLS) is a British specialist facility providing rehousing, maintenance, repair and manufacturing of cinema and broadcast lenses.

Overview

True Lens Services (TLS) is not a single device or lamp, but a British specialist in lens technology based in Barwell, Leicestershire. The company is internationally known for three areas of activity: the rehousing of vintage photo and cinema lenses into robust, cinema-ready mounts, the servicing and repair of film, broadcast, and projection lenses, and the in-house manufacturing of proprietary optics (including their own Vega series).

The core of their offering is to preserve the optical character of vintage lenses while bringing them mechanically up to the standard of modern cinema production: precise focus pull, standardized gear rings, uniform front diameters, and production-ready mounts.

Rehousing Process

During rehousing, the original optics are transferred into a newly manufactured housing made of high-quality aluminum alloy and stainless steel. According to TLS, the components are manufactured in-house, with the exception of bearings. The mechanical focal points are:

  • Focus Mechanics: A non-linear, cam-driven design with nearly 300 degrees of rotation, which distributes focus markings more evenly than the narrow original scale of photographic lenses.
  • Backlash Elimination: A sprung follower with chamfered flanks eliminates backlash and image shift during focus pulls.
  • Stops: Stainless steel stops for focus and aperture.
  • Standardization: Uniform gear ring positions for focus and aperture relative to the mount flange, ensuring compatibility with follow focus and motor systems.

Typical Product Range

TLS rehousess classic cinema lenses for cinema use as well as photographic optics. Examples from their range:

CategoryExamples
Classic Cinema LensesCooke Speed Panchro, Bausch & Lomb Super Baltar, Kowa Cine Prominar, Lomo Anamorphic
Photo/Still Lenses (Cinema Converted)Canon K35, Canon FD, Leica R, Zeiss Contax/Super Speed, Nikon AI/AI-S, Olympus OM, Petzval, Mamiya 645

Typical standardized features: PL and LPL mounts with flange focal distance adjustable via shims, front diameters mostly 110 mm (special lenses sometimes 125 or 143 mm).

On-Set Usage

For the camera department, a TLS rehousing means that an optically appealing vintage lens with its characteristic "look" is preserved, but can be operated like a modern cinema lens: long, repeatable focus pull, uniform gear rings for motors and follow focus, consistent front diameter for matte boxes, and a robust PL/LPL mount. TLS conversions are commonly found in rental houses as sets; well-known references include the Cooke Speed Panchro conversion for Mr. Turner and the use of re-housed Petzval optics in Poor Things.

Perspectives

Cinematographer

Als Kameramann schätze ich TLS-Objektive für ihren charaktervollen, organischen Look mit sanften Bokeh-Übergängen und dezenten Aberrationen. Die einheitlichen Gehäuse und Gear-Ringe ermöglichen mir schnelle Objektivwechsel am Set ohne ständige Follow-Focus-Anpassungen. Der Vintage-Charakter dieser Optiken verleiht meinen Bildern eine besondere Wärme und Persönlichkeit, die mit modernen Objektiven schwer zu erreichen ist.

Director

Für mich bieten TLS-Objektive die perfekte Möglichkeit, meinen Filmen einen unverwechselbaren visuellen Stil zu verleihen, ohne das Budget zu sprengen. Die organische Bildsprache dieser Vintage-Optiken unterstützt emotionale Erzählmomente und verleiht selbst digitalen Aufnahmen eine filmische Anmutung. Die Zusammenarbeit mit Kameraleuten, die diese speziellen Objektive beherrschen, eröffnet neue kreative Gestaltungsmöglichkeiten.

Producer

TLS-Objektive stellen eine kosteneffiziente Alternative zu teuren Master-Prime-Sets dar, ohne Kompromisse bei der Bildqualität einzugehen. Die Investition in ein TLS-Set amortisiert sich schnell über mehrere Produktionen, da diese Objektive einen einzigartigen Look bieten, der bei Kunden sehr gefragt ist. Zudem sind die robusten Gehäuse wartungsarm und reduzieren Ausfallzeiten am Set.
