Description

The FUJINON XK6x20 20–120mm T3.5 is a professional Super 35mm PL-mount cinema zoom lens from FUJINON’s XK Cabrio series. Designed for demanding film, television, commercial, and broadcast production, it combines a versatile 6x zoom range with constant T3.5 transmission throughout the entire focal-length range.

Covering 20mm to 120mm, the XK6x20 can handle wide establishing shots, medium framing, interviews, and telephoto compositions without requiring a lens change. Its compact design and detachable digital servo drive allow the lens to be configured for either traditional cinema-style manual operation or servo-assisted zoom and focus operation.

Versatile 20–120mm Range

The 20–120mm range provides an exceptionally useful focal-length range for professional production.

At 20mm, the lens provides a wide perspective suitable for establishing shots, interiors, landscapes, and large environments. At 120mm, it provides significantly tighter framing for interviews, performances, events, and detail shots.

This allows productions to cover a large portion of a shoot with a single cinema zoom instead of repeatedly changing prime lenses.

Constant T3.5

Unlike many variable-aperture zoom lenses, the XK6x20 maintains T3.5 transmission throughout the entire 20–120mm range.

There is no T-stop loss when zooming from 20mm to 120mm, allowing the operator to maintain consistent exposure throughout a zoom.

This is particularly valuable for:

  • Live events
  • Interviews
  • Narrative filmmaking
  • Commercials
  • Documentary production
  • Studio production
  • Multi-camera shoots

Cinema-Grade Manual Operation

The XK6x20 is designed to provide the tactile control expected from a professional cinema lens.

The 200° focus rotation provides substantial travel for precise manual focusing, while the 0.8 MOD gear pitch allows compatibility with standard follow-focus, zoom-control, and lens-motor accessories.

The focus scale can also be configured to display distances in either feet or meters.

Detachable Digital Servo Drive

One of the defining features of the XK Cabrio series is its detachable drive unit.

With the servo attached, the lens can provide powered zoom and focus operation suitable for broadcast-style and studio production.

With the drive removed, the lens can be operated more like a conventional cinema zoom using its mechanical focus, zoom, and iris controls.

This hybrid design makes the XK6x20 particularly versatile for rental applications because one lens can support both cinema-style and servo-assisted production workflows.

4K Optical Performance

FUJINON designed the XK6x20 for high optical performance compatible with 4K cameras.

The lens is intended to maintain high-quality imaging throughout its 6x zoom range, making it suitable for modern digital cinema, television, and commercial production.

Macro Capability

The lens includes a macro function.

Standard minimum object distance from the image plane is approximately 1.1m / 3.6 ft, while macro operation allows focusing down to approximately 0.4m / 1.3 ft.

This provides additional flexibility for close-up product shots, detail shots, and other applications where a conventional cinema zoom may not focus closely enough.

9-Blade Iris

The XK6x20 uses a 9-blade iris designed to provide natural-looking out-of-focus rendering.

FUJINON specifically developed the iris design to produce smoother and more pleasing bokeh, particularly when point light sources appear in the background.

Applications

The FUJINON XK6x20 is ideal for:

  • Feature films
  • Television production
  • Commercials
  • Music videos
  • Documentary filmmaking
  • Corporate production
  • Interviews
  • Broadcast
  • Live events
  • Sports production
  • Studio production
  • Multi-camera productions
  • Concerts
  • Wedding cinematography
  • Theater and performance filming
  • Reality television
  • ENG-style production

Field of View

At a 16:9 Super 35mm image format, the lens provides approximately:

  • 20mm: 63°41′ horizontal × 38°30′ vertical
  • 120mm: 11°49′ horizontal × 6°40′ vertical

This gives the lens a useful transition from wide-angle coverage to strong telephoto compression without changing lenses.

What’s Included

A standard KR Camera Rental package can include:

  • FUJINON XK6x20 20–120mm T3.5 lens
  • PL lens mount
  • Detachable digital servo drive unit
  • Front lens protection/cap
  • Rear PL mount cap
  • Lens support hardware, if required
  • Appropriate servo power/control accessories, depending on package

For a rental listing, I recommend specifying clearly whether the servo drive unit is included, because the XK6x20 can be configured with or without the drive system.

Compatible Cameras

The XK6x20 is designed for Super 35mm PL-mount cinema cameras.

It can be used with professional PL-mount systems such as:

  • ARRI ALEXA Mini
  • ARRI ALEXA 35
  • ARRI ALEXA Mini LF with appropriate PL configuration
  • Sony VENICE with PL mount
  • RED cinema cameras with PL mount
  • Blackmagic URSA Cine / URSA Mini Pro with PL mount
  • Other Super 35mm PL-mount cinema cameras

The camera must have a compatible PL mount and sufficient support for the approximately 2.9kg lens package.

Why Rent the FUJINON XK6x20?

The XK6x20 is an excellent rental lens for productions that need the flexibility of a zoom while maintaining the mechanical control and image quality expected from a professional cinema lens.

Its combination of:

20–120mm + constant T3.5 + Super 35 PL mount + detachable servo drive

makes it particularly useful for productions that move between cinema-style operation and broadcast-style servo operation.

For a professional camera package, it can function as a versatile all-purpose cinema zoom and significantly reduce the need for frequent lens changes.
