It is a c-mount lens and can be adjusted like a c-mount lens. All I can say is that I had the 5.5mm Fujinon collimated to my Mekel cine 8 with no problems. The lens can be adjusted just like other c-mount lenses. The same goes for the ZC1000, no problems collimatng C-mount lenses. The only cameras I've ever experienced collimation problems using c-mount lenses are the latter day beaulieus, 6008/7008, there's something quirky about their spacings. The zoom lens for the ZC1000 is an EBC lens too., along with the 5.5mm. With the ZC1000 I bought in the 90's, both lenses came in the manufaturers box.

The century lenses are both c-mount. No data sheet, but there was a 16mm version of the 3.5mm Super Wide made called the Extreme, it's a similar looking lens but has a different set of front elements to the super 8 version. The Fujinon 5.5mm lens was made specifically for the Fujica ZC1000 c-mount single 8 camera and was sold with it along side the Fujinon zoom.

The cinegon isn't the only prime lens calculated for super 8, both the century 2.5mm & 3.5mm lenses were made specifically for S8mm format as well as the Fujinon 5.5mm. FUJINON 5.5MM CENTURY 3.5MM
