Best gimbal for Sony A7IV with heavy lens? DJI RS 3 Pro vs RS 4 Pro?

Great question! I've used both extensively with a similar setup (A7IV + 24-70 GM II). The RS 4 Pro's automated axis locks are a game-changer for speed when you're setting up or breaking down, especially in run-and-gun scenarios—it saves you maybe 15-20 seconds each time, which adds up. But more importantly, the RS 4 Pro has improved motors and a better balancing algorithm, so with a heavy lens like the 24-70 GM II, you'll get smoother pans and less motor strain. I've noticed the RS 3 Pro can sometimes get a bit warm with that combo, but the RS 4 Pro handles it fine. For autofocus, you don't need the focus motor—the A7IV's AF is superb, and the gimbal's native control via Bluetooth is enough. Just make sure to update the firmware and use the DJI Ronin app to set the joystick sensitivity. If you're on a budget, the RS 3 Pro is still solid, but the RS 4 Pro is worth the extra $200 for the convenience and future-proofing. Also, consider the RS 4 Pro's new RSA communication port—it's handy if you ever add a follow focus later.

Thanks lenshub80 for the detailed comparison! I decided to go with the RS 4 Pro after reading your points about the motor strength and axis locks. I picked it up yesterday and tested it with my A7IV and 24-70 GM II—balanced perfectly with no issues. The automated locks are indeed super convenient. I also updated the firmware and connected via Bluetooth, and the AF works flawlessly for walking shots. I'm glad I didn't need the focus motor. Appreciate the advice, this thread solved my dilemma!
