Moment Case / 58mm Tele DJI Osmo Mobile 6
Finally, I tried the heavier Moment 58mm Tele and actually the gimbal seemed to be fine with it. Again, I was able to perform focus pulls. I could even zoom in a little. Obviously, with a conversion lens you can’t switch lenses.
The only issue is that the 58mm tele obstructs the gimbal if you turn the handle on the roll axis too far.

So that gives you an idea of what you can add to your smartphone. If you wanted to add more, I think you would need to use counterweights. Like I say, DJI doesn’t officially recommend you do this.
My guess is it will place a little more strain on the motors, especially with the 58mm. This means your gimbal battery might run down faster, the motors themselves might wear out a little quicker.
