Home / Photon Cage / RASA 11 system
A Photon Cage, our PRO M68 filter slider system and a RASA 11 camera mount, built to put 50 mm and 50×50 unmounted filters in front of full-frame sensors at f/2.2.
The PRO filter slider system steps up to a 68 mm baseplate and dedicated filter holders. It bolts to any Photon Cage and takes you from 2-inch mounted filters to 50 mm round or 50×50 square unmounted glass.
Paired with our RASA 11 M68 mount, it keeps the light cone clear to the corners of a full-frame sensor.
We modeled the RASA 11 light cone at 72.8 mm of backfocus through every part of the train, so you can see exactly where filters and mounts sit relative to the corners of a full-frame sensor.
Both packages include full 4-corner tilt and independent backfocus.
