Classic Nikon. Modern Cinema.

The story of Nikon's legendary lens heritage began in 1959 with the introduction of the iconic F-mount. Building on that legacy, the Nikon AI and AI-S series went on to earn a reputation as some of the finest vintage optics ever produced, admired by filmmakers for their balanced image quality, natural rendering and timeless character.

Now, TLS has carefully re-engineered these iconic optics into a professional cinema housing, preserving everything filmmakers love about the original glass while delivering the precision, reliability and usability demanded by modern productions.

Why Choose TLS Rehoused Nikon AI/AI-S Lenses?

Nikon AI and AI-S lenses occupy a unique place in modern cinematography. They deliver a cleaner, more controlled image than many vintage lenses, while retaining enough character to avoid feeling clinical.

Originally introduced in 1977, Nikon's Automatic Indexing (AI) system revolutionised lens design by allowing quicker lens changes and improved aperture communication. The AI-S evolution followed in 1981, refining aperture control even further and creating one of Nikon's most consistent lens families.

TLS has taken these legendary optics and transformed them into a true cinema lens set, designed to perform on today's productions without sacrificing the distinctive Nikon look.

Beautiful Bokeh

The TLS Nikon rehousing replaces the original polygonal iris with a custom-made circular iris, creating a smoother and a subtly enhanced character. The replacement iris blades also feature a flat black anti-reflective coating to minimise unwanted reflections.

This produces:

• Smooth, rounded bokeh
• Natural background separation
• Soft focus transitions
• Pleasing highlight rendering

Rather than distracting the viewer, the out-of-focus areas complement the subject, creating images with genuine depth and atmosphere.

Whether shooting portraits, dialogue scenes or intimate close-ups, the bokeh enhances storytelling without overpowering the image.

Natural Depth & Focus Fall-Off

The Nikon AI/AI-S lenses create a gentle transition from sharp focus into softer backgrounds.

Instead of abrupt focus separation, they deliver gradual depth that feels natural and immersive.

This subtle rendering helps subjects stand out while maintaining detail and texture throughout the frame, making the lenses particularly well suited to narrative filmmaking.

Controlled Flares

Unlike some vintage optics that flare aggressively, Nikon AI/AI-S lenses produce controlled, elegant flares. They retain excellent contrast while introducing just enough flare to add atmosphere and emotion without overwhelming the image.

This gives cinematographers greater creative flexibility without sacrificing image quality.

Low Light Performance

With fast maximum apertures from T1.3 across core focal lengths, the TLS Nikon AI/AI-S range performs exceptionally well in available light.

Wide open, the lenses maintain:

• Excellent centre sharpness
• Smooth contrast
• Beautiful subject isolation
• Cinematic rendering

This makes them ideal for:

• Night exteriors
• Interior practical lighting
• Documentary work
• Natural light cinematography

Natural Colour & Skin Tones

One reason Nikon AI/AI-S lenses remain so popular is their colour reproduction.

They produce:

• Natural skin tones
• Slightly cooler colour rendition
• Gentle contrast
• Low chromatic aberration

The result is an image that feels clean and realistic while still retaining the character and personality associated with classic vintage optics.

Full-Frame Coverage

Designed for today's cameras, the TLS rehoused Nikon AI/AI-S lenses provide generous image coverage across modern full-frame sensors.

This makes them suitable for a wide range of professional cinema cameras while preserving their classic optical signature.
