Glad to read about the Nest Gimbals. I have the Sigma 150-600 Sport and will be looking at a gimbal soon. Have not gotten a tripod yet either. I'm inquiring about what kind and size of tripod and what size Nest Gimbal head you purchased. I've gone crazy looking at all that's out there. Really a lot of choices to chose from. You really want to get your selection right the first time or you'll be spending more money down the road getting a different choice. I want to stay with a Nest Gimbal set up. With a Tripod that is compatible also. Thanks for your input. I was thinking of driving out there to MT's place but have not decided yet. My better half is not too welcome to that idea.

The dock is soooo easy to use . Just plug n play. I'm the dumbest computer person in photography and I can use it. But getting the focus adjusted exactly how I wanted for my 2 art lenses took me two days each. It was time consuming and thousands of pictures testing. But I was so picky repeating shot after shot eliminating missed focuses. I did this over and over. Probably spent 20 hours on each lens. I'm just anal like that but now these lenses really nail the focus in technical situations, lower light and wide open. Exactly what the Sigma lenses are not known for. I love my lenses and do plan on getting the 150-600 Sport . I'll probably drive me crazy setting everything . I read a review where a professional photographer super tuned his 150-600 sport and had it on d750. The results were phenomenal and he really bragged up the lenses performance. This was even before the latest firmware updates. For a Zoom of this range I think it's performance would be super hard to beat. I've also been looking at the Sigma 500 f/ 4.5 for the supposed extra resolution and better low light performance. So I'm up in the air between the two. If anyone has any information comparing the two please let me know.
