The S35xFF Expander scales the Super-35 image up to 44.6 mm, covering full-frame format (ø 43.5 mm) and even the RED Dragon 8K format (46.3mm). Special attention was taken while designing the extender to ensure minimum light fall off and maximum image performance up to the edge of the larger sensors.

The S35xFF Expander can be used on lenses with a maximum aperture of T2.0 and provides the best performance at T2.8 for optimal resolution and sharpness.
The movement toward larger format sensors, such as Arri ALEXA LF, Sony VENICE , Panavision Millennium DXL2, and Arri ALEXA 65  is still in progress. Larger sensors deliver a film-style look with an interesting bokeh due to their very shallow depth of field. These new cameras require lenses that can cover larger sensor sizes or an expander that allows cinematographers to use their favorite S35 lenses. At the moment, there is still a limited amount of professional cine optics for the large format in comparison to the lens choices available for S35 sensors.

The current version of the S35xFF expander is designed to cover large format sensors using lenses that have a maximum T-Stop of 2.0 with ideal performance achieved at T 2.8, well within the working T-Stop range of many popular S35 zoom lenses.

The S35xFF expander:

  • can be used with most PL mount S35 optics
  • has a UMS PL mount, allowing it to be used with other mounts, such as standard UMS LPL, EF, E, FZ, and FZ Mark II
  • is NOT compatible with mirror shutter cameras

In conclusion, the S35xFF makes the image circle larger: from a diagonal of approximately 30 mm of your Super35 format lens to the larger diagonal of Full Format. Te image is expanded by a factor of 1.45x. Light loss is about 1 stop. (IB/E Optics recommends best performance at T2.8, and a maximum aperture of T2.0)
Depth of Field stays about the same as the original Super35 format. So, if DoF of a 50 mm S35 lens was 10 inches, it remains the same 10 inches with the expander covering Full Format.
Angle of View also remains roughly the same. Your 50 mm lens on a regular Alexa covers about the same angle of view as a 50mm with the
S35xFF on an Alexa LF.
