I'm needing to pull iris on a Fujinon ENG lens for a shoot and the camera I'll be flying isn't set up with any kind of wireless telemetry.

Does anyone know the lens gear pitch for the iris ring on one of these lenses? I've read it's 0.4 pitch, but I want to make sure about it.

 

Pic attached is of the lens I'm going to be flying.

Hi David,

If you have the 4 gears that come with an FMG.6 motor, it's there, as well as one of the gears that come with the M-One motor. Not sure what Lens Motor you have. But please hand the Transmitter to someone in charge, like the DP, or someone in the camera department, don't take the responsibility for pulling Iris yourself. Are you using a 2 channel system for this? for the Focus and Iris?

 Have a fun shoot

Osvaldo, when I got my M-one, it only had the .6 for fuji and .8 gears with it. For the most part, it's never been an issue. I'm renting a second bartech for this and handing the focus to the 1st and the Iris to the DP. I've made it very clear that Iris is not something that can be pulled from the sled.
