What is the gear pitch for zeiss superspeed lenses?
Are they 32, is that compatible with panavision lenses?
Thanks, Chris Hood

Chris,

"What is the gear pitch for zeiss superspeed lenses?"

32 Pitch for focus
48 pitch for iris
(note Heden claims that .5 is the same as 48 pitch. In reality, close but no cigar. You might get away with it, but there is a good chance the gear will slip off because it is not exact. True 48 pitch works a lot better)

Panavision:
32 Pitch for focus
64 Pitch for Iris
