Just saw this thread and wanted to jump in because I was worried about the exact same thing with my FX30. Since you are doing a wedding, you really gotta be careful about those HDMI and XLR ports getting bumped during the reception. I would suggest looking at the 8Sinn Cage for Sony FX3 FX30 because they leave plenty of room for the top handle and the cable protection is top tier. It might be a bit more than the budget ones but keeping your ports safe is worth the extra cash imo. Quick tip: make sure to get a cage that has a dedicated attachment point for the Sony handle so it doesnt wobble while you are moving. You might want to check out the RigBuilder site or some of the technical breakdown videos by Gerald Undone on YouTube... he usually shows exactly how much clearance you actually get for the XLR unit. Maybe consider the SmallRig NATO Side Handle 2427 too since it is lightweight and super secure. Good luck in Chicago, hope it goes smooth!

Jumping in here. I have been quite happy with how my current rig has performed over the last few months. I prioritize stability and equipment safety above everything else, so I spent a while looking at the technical specs for cage clearance.

• The SmallRig Full Cage for Sony FX30 FX3 4183 is basically the standard for a reason. Unlike the mamba style, this one includes a dedicated top plate that is fully compatible with the Sony XLR handle.
• It secures the body at three different points. This is huge because it prevents the camera from twisting inside the cage, which is a common failure point on cheaper setups.
• I paired it with the SmallRig Wooden Side Handle 2093C. It is very comfortable for long days and keeps the total weight low. This setup is very reliable and stays within your budget easily. It doesnt block the top dials either, so you wont have issues changing settings on the fly during a wedding.

I've been shooting with Sony bodies since the early a7s days and honestly I've wasted so much money on cages that looked cool but felt like holding a brick with sharp edges. Over the years, I've learned the hard way that sleek is almost always a trap. You think you want something slim for the weight, then you realize you cant actually get your thumb on the record button or the top dials without doing some weird finger gymnastics. It’s a total nightmare when things are moving fast at a wedding and you're losing light... plus it just cramps your hand after three hours. The biggest mistake I see people make with the FX30 is ignoring how much space that XLR top handle actually needs. I once bought a pro cage that claimed it was compatible, but as soon as I bolted everything on, the clearance was so tight I couldn't even plug my cables in without stressing the ports. If you're doing a Chicago wedding, you're gonna be moving between cramped prep rooms and windy outdoor shots. You really need something that lets you grip the actual camera body when you aren't using the top handle. In my experience, you should avoid anything that wraps too tightly around the right-hand grip. You want a cage that leaves that area mostly open so you can actually feel the camera's natural ergonomics. Also, stay away from side handles that use those tiny little hex screws for attachment. They always wiggle loose by the time the reception hits. Stick to a solid rail system or a Nato rail setup. It adds a tiny bit of weight, but it beats having your rig fall apart mid-vows, trust me.
