Curious about one thing: before I give a final recommendation, are you planning on running a full cage or heavy brass ND filters on that Sigma? The Sony a7 IV paired with the Sigma 24-70mm f/2.8 DG DN Art for Sony E is a beast, and since that lens is internal-zoom-challenged (it extends!), it can realy mess with your balance mid-shoot.

TL;DR: The standard DJI RS 3 is decent, but for a front-heavy wedding rig, I'd suggest the DJI RS 3 Pro or the Zhiyun CRANE 4 for better motor overhead and reliability.

So basically, I'm a bit cautious about the smaller gimbals for your specific kit. I've seen people push the DJI RS 3 to its limit, and while it works, the motors can get warm and start micro-vibrating after a few hours. For professional wedding work, you need that extra torque headroom. The Bluetooth shutter on the a7 IV is actually super reliable—basically magic for avoiding cable snags—but it does drain the camera battery slightly faster.

If portability is the main goal, you gotta be careful. A lighter gimbal like the Zhiyun WEEBILL-S would definitely struggle with that Sigma glass. I'd highkey recommend looking at the DJI RS 4 if your budget allows, as the Teflon-coated axis arms make balancing a front-heavy lens way smoother. Just make sure you calibrate it every time you change focal lengths! Anyway, let me know about the cage setup... it makes a huge difference for the center of gravity. gl!

yo, jumping in here real quick! Ngl, everyone's gonna tell u to buy the newest shiny stuff, but I’ve had a different experience when trying to save some cash. That Sigma lens is seriously heavy, and ur arm is gonna feel it after three hours of wedding footage.

Respectfully, I'd consider another option instead of the latest RS 3 or Weebill models if u wanna save a few hundred:

* Feiyu SCORP-C 3-Axis Gimbal Stabilizer - This thing is a total sleeper. It’s usually way cheaper (like $260) and the built-in handle makes low shots so much easier on ur wrists during long days.
* Look for a used DJI RS 2 Gimbal Stabilizer. In my experience, the motors on the older RS 2 are actually stronger for front-heavy glass than the base RS 3. You can find them for around $300 now if u look around.
* Tbh, be careful with the Bluetooth shutter for weddings. It’s cool for vlogs, but I've seen it drop connection. Just use a physical cable if u want 100% reliability.

Being cautious with ur gear choice now saves u a headache (and money) later. gl!

> I’ve been eyeing the DJI RS 3 or the Zhiyun Weebill 3... I’m mostly doing wedding films and travel vlogs

Hey! Honestly, I’m kinda new to video, but I’ve been SO happy with the DJI RS 3 Gimbal Stabilizer for my a7 IV. The Bluetooth shutter is basically magic and super easy to setup. Even with that chunky Sigma lens, it doesn't vibrate or anything, which was my biggest fear lol. It’s light enough for long travel days too! Highly recommend it tbh. gl!

Finally someone says it. Ive been thinking this for a while but wasnt sure.

Tbh I've spent a lot of time testing the major brands with my a7 IV. I started with a setup from one of the smaller manufacturers because of the price point, but I found the motor calibration really struggled with the shifting center of gravity on that Sigma when it extends. I eventually jumped over to a more mainstream ecosystem and the difference in the stabilization algorithms was pretty immediate. I learned that payload specs are basically just marketing fluff if the motor torque isnt there to back it up. Regarding that wireless shutter control, it has been a massive quality of life upgrade for me. No more snagging cables mid-rotation! It took me a minute to figure out the menu settings on the Sony side to get it to pair, but once I did, it has been rock solid. If you're doing weddings, you will definitely appreciate not having to mess with tiny cables every time you need to switch batteries or re-balance. My current setup feels way more balanced because there is zero cable tension pulling on the tilt axis.
