What is a Hirschmann clamp and what is it used for?

Recommended Posts

Hello everybody, I'm reading the Arri 416 camera manual and I'm running into some terms that I do not kno wthe meaning of. One of them is the Hirschmann clamp, what is it and what's its function? It's said that it's used to "replace fibre screens and the field lens" but I do not know what it means.

Thanks so much in advance for te help,

Thanks so much! One last thing, looking at the images of the camera on the manual on the right side on the lower part there is something called "Film transport pitch adjust". What is that?

It's to match the pulldown pitch to the perf pitch, to reduce running noise.

Generally pitch adjustment should be left to prep at the rental house. It's not something that's commonly done on-set. Especially with the Arri 416 and SR3, those cameras share a movement and seldom need major adjustments done by anyone besides a tech during regular service intervals.
