The Arri Alexa 15mm steel bar system is sturdy enough to support a 6kg zoom lens like the Optimo 18-80 without problems
An Alura 45-250 zoom has been successfully mounted on Alexa using the rod system
Increased distance between the support plate and lens mount creates greater leverage and mechanical stress on the mounting system
The Alexa rod mounting system is specifically designed to hold heavy lenses

The discussion focuses on static mounting rather than stabilized rigs like Steadicam
One participant expresses hesitancy about the longer lever arm created by Alexa's lens mount position compared to other camera systems
The specific performance with the Optimo 18-80 on Alexa bars was not definitively tested by all participants
