Hi Andy,
Thanks for the backing and sorry about the issue here. So this is the first (and hopefully the last) of such focus issues we've seen. We order these from Sunny (so quite expensive) and the expectation is that they'll be top-notch as well.
So the lenses are focused and then glued (to my knowledge). I just tried to rotate one with my fingernails, and I couldn't break the lens free. So I am suspecting we'll need to replace your unit.
And I actually just tried some mini-vice-grips on the camera module (a spare one) and the lens will not budge.
If you shoot an email to support@luxonis.com we will get you taken care of. And if you don't mind, could you share a photo of the focus here or on your email?
Thanks again and sorry about the focus issue here.
