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,

Davide

It refers to this ground glass tool, used to remove the ground glass/fiber screen from the viewing system.

All right! Thank you so much, only one last thing, what do you exactly mean by "fiber screen"?

The viewing system of the 416 uses a fiber-optic screen instead of a ground glass, which allows it to transmit more light through the viewfinder and make the image you see brighter.

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.
