Scarlet boot up changes focus on EF lenses, even in MF

[Neil Cronin]

My EF lenses get their focus motors spun by my Scarlet when it starts up, even when the lenses are physically switched to manual focus and the Scarlet is set to manual focus. It happens with my 24L and 50L. It's not the biggest problem in the world, but it does mean that I have to refocus between power cycles, which is both surprising and annoying.

Is this expected and/or is there a way to turn this off?

I think it has to do that in the current iteration to properly map the lenses and make them usable. It would be nice to be able to turn it off for full manual.

Hm, I know nothing about the protocol to talk to EF lenses, but certainly the lens could announce itself using the model identifier rather than the camera spinning the glass and guessing? Scarlet is the only camera that I know of that spins up the focus motors when the camera starts.

Mine does this as well. Annoying, but not the end of the world. If someone knows how to turn it off, I'd like to know. But I'm thinking its as previously stated, its some initialization script that causes it.

It may also serve as a troubleshooting measure, to determine and/or verify that the lens' motor is in fact responding to commands from the camera body. Think of it like the trouble indicator lights on the dash of your car. When you turn the ignition on they illuminate briefly, so that you can verify that the bulbs are not burned out. Just a thought.

Unfortunately it happens all the time. Not a deal killer, but it can be a pain if you just set your marks and then have to change the battery.

But truthfully once you know about it you tend to work around it. Plus, it gives me an excuse to push for cine glass on projects.

yes , I wish they would look into this issue.
