Do you mean you're missing new lenses or Super8 lenses in General ? The Kinoptik Super-Tégea F1,9mm is still in production and covers Std. 16mm, the Tégea 5mm and 5.7mm even cover Super16 all these lenses are available in C-mount and are certainly very expensive. Kinoptik is one of the most underrated Cine lens manufacturers, these days everyone wants German lenses but the Kinoptiks are just as good imo.
The camera is equipped with a C-Mount and looks more like a Gordon G.S.A.P than an Arri 416
