Best budget-friendly gimbal for Sony A7IV with heavy 24-70mm GM II?

I feel your pain – the Ronin SC is rated for 2kg, and your combo with the A7IV (approx 1.4kg with battery and card) plus the GM II (695g) is already over 2kg, so you're pushing it. I've been using the DJI RS 3 (non-Pro) with my A7IV and the Tamron 35-150mm (which is even heavier at 1.2kg) and it handles it flawlessly. The RS 3 has a 3kg payload, and the new axis locks make balancing a breeze – you can lock each axis independently, which is a game-changer for quick setups. It also has a built-in 1.4-inch touchscreen for quick mode changes, and the Bluetooth shutter button works with Sony via the USB-C cable (just make sure to set the camera to 'USB connection' mode).

I found a used RS 3 for around $350 on eBay, so it's definitely within your budget. The Zhiyun Crane M3S is also a solid option – it has a higher payload (6.5kg) and is lighter, but I've heard the balancing process is a bit more finicky, and the app isn't as polished. The Weebill S is older and might have less torque, but it's cheaper. If you can stretch a bit, I'd go with the RS 3 – it's the best value for your setup. Also, don't forget to balance with your accessories attached, and use the 'Motor Tune' feature in the DJI app to calibrate for the heavier lens. That should eliminate the jitters.

Thanks for the detailed response, rendercore95! I actually took your advice and picked up a used DJI RS 3 from a local photographer for $330. I spent an afternoon balancing it with the A7IV, the 24-70mm GM II, and my wireless mic (Rode Wireless Go II) plus a small monitor, and it's rock solid. The axis locks are a huge improvement over the Ronin SC – I can get it balanced in under two minutes now. I also ran the Motor Tune in the app as you suggested, and the footage is buttery smooth, even when walking at a brisk pace. The touchscreen is intuitive, and I love that I can switch between landscape and portrait mode quickly for social clips.

I just wanted to say thanks for the recommendation – it was exactly what I needed. If anyone else is on the fence, the RS 3 is a fantastic choice for the A7IV with heavier glass. Problem solved!
