The S35xFF Expander scales the Super-35 image up to 46.4mm.

This covers full-frame format (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. This 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.
