Hi i have recently found this piece of lens from a film guy, i searched a lot but found nothing about that. i am attaching pictures so maybe you have some knowledge about that. Its name is ( Prima Anamorphic 16-P ) according to my understanding.
i have tested the lens by just placing infront of my manual 55mm prime lens and its produces nice golden flares.
let me know about this lens, if anyone have some info.
