Thank you! In the case of these larger lenses projector lenses, their minimum focus distance is around 15m-20m and their maximum focal distance extends past infinity for the focal plane of the camera. Thats why shortening the distance is required for this lens. I recently came by a lot of well preserved yet massive anamorphics for basically nothing in auction, in their current state they are very impractical for filming but since I have so many I can hack away, experiment and adapt.
