today was the 1st time i had chance to play with the Ronin S and active track. Overall impressions are good and it works well.
with my son walking around in frame you can see below it tracks him perfectly
camera was Canon EOSR with a 16-35 f2.8 and a google Pixel 3 which isnt on the supported list but... it works fine
now my gripe....... can the phone mount be redesigned so that the phone is offset ? this would mean that you could have the phone camera lens aligned with the main camera lens. Just an inch to the right or left would be perfect.
