After getting the GH4 + 12-35 f2.8 working on the DS1 (out of the box) I wanted to setup something lighter to see how it handles smaller cameras. When I am shooting a live event (i.e. weddings) I want to use the DS1 with my GX7 + 12mm f2.0 so I can just leave it on the gimbal all day and use my GH4 for my main cam. With this in mind I set out to see if I could get this pair to balance and perform well on the DS1. I had little trouble balancing the pair (the GM1 + 12mm was just too tiny to really balance well) but the default profiles had way too much power for such a small combo. Even profile 3 and 4 which come setup for smaller combos had the shakes pretty bad. So I decided to try the auto tune ability of the 32b alexmos board as shown here by Emm: So I set the gimbal up on a sturdy tripod and stating with the profile 3 power settings I auto tuned the PID for each axis alone, twice (took about 15 mintues). Much to my surprise when I removed the gimbal and tested it it worked really well with this lighter setup. I then updated profile 3 and 4 to use then new PID settings. Now I can fly the GH4 + 12-35mm or GX7 + 12mm with a quick rebalance and a simple profile change. I plan on shooting the GH4 + 12-35mm over the holidays and I will report back with some actual footage early next year. Thanks,
