RPZ 18-85 Mount Question

[Scot Yount]

Sorry for the noob question, but here is my scenario. I have a Scarlet MX with the WC PL mount. I also own a RED Pro Zoom 18-85. Until recently, I had been mounting it without support and just using it only in a studio setting. (It is so big that there really is no other other way to use it.) I bought the new Tilta support for it, just released. (Not sure they don't know it isn't made any more.) 200 bucks, and it comes with the bridge plate for 19mm rods. Not as slick as the OptiTek collar but a lot cheaper. Here is the question. How much upward pressure do I put on the support unit to properly support the lens? In a test, zoomed in at 85mm, at 1k, I can see the image moving up and down with the slightest adjustment of the height knob on the lens support. How do I know what is right?

Nobody has a thought?

You don't need to be putting upward force on the lens, just put the support on the lens so that the lens rests on the support system. You just don't want the lens weight barring down on the mount because if it bends you'll end up with focus issues.

When I was working with production zooms, I did my initial setup with the camera tilted up 90 degrees. Then I would adjust the lens support appropriately, tilt back to neutral position and slide the plate to balance the camera/lens.
