Now that the Birdycam has started shipping, i'm hearing a few questions and comments about tuning the PID settings to work better with a lightweight camera. I myself found the system oscillating when my setup was too light weight. Here's a video showing you a few simple settings you can change to get it working better.
Now just from experience I know what to sort of look for, but there's no exact magic number. All I could tell was that I needed to reduce my PID settings and those are numbers that seemed to work. In fact I tested my 12-35mm F/2.8 OIS with my new profile and it still worked just fine.
After making changes to your system you should take it out and use it as you normally would, and then decide if you need to make further changes. Always make changes to one area at a time instead of making large blanket changes across every tab. Most importantly always make a backup or document your prior settings before you make any changes. If you have any other questions, you can leave a comment below.
