How low did you bring down the speed?
It’s so gosh darn intermittent and now I find it’s sometimes the zoom out, not the zoom in.
I’m finding a speed of 10 working now (sheesh!).
Someone else on another forum tried between 1 and 3 to do a slow creep and spotted the same problem.
Try a speed of 5 or maybe even 1 to 3 range as someone else saw it.
What I find is if I start at 0 or 99 depending on which way you go, it will occasionally pause or begin to step from number to number. I had to go through the entire range to see it happening (0 to 99 or 99 to 0).
It’s really hard to discern issues when you don’t have a 2nd camera to compare it to.
Thanks for checking.
