You can get the DJI RS 4. And if you just pair with a lightweight lens, get the DJI RS 3 Mini.

Regarding what #3 said about "DJI RS 4 is highly recommended."

• I totally agree because reliability is everything when you have an expensive body like the a7R III! You really want to know your gear is safe while youre moving around. Ive tested a few and these are the most rock-solid ones imo:
• DJI RS 4 Gimbal Stabilizer is basically the gold standard for safety. The automated axis locks are a total lifesaver because they keep everything clamped tight when you turn it off so it doesnt flop around. It feels so secure!
• Zhiyun Weebill 3S Handheld Gimbal is also fantastic and feels super sturdy in the hand. I love the sling grip design because it makes it way harder to accidentally lose your balance while filming low angles. Both are amazing options that wont let you down. Definitely go for one of these if you want that extra peace of mind! Hit me up if you need any help with the balancing process, its easier than it looks.

I use weebill s, works great and never has any problem.

DJI RS 4 is highly recommended.
