Just catching up on this thread and honestly, you gotta be careful with how you allocate that $700 for a wedding. I learned the hard way back when I first started that cutting corners on power and media is a recipe for disaster. I once had a generic battery die on me mid-procession and it took forever to swap because the cheap casing had slightly expanded from the heat. Was a total nightmare. Make sure you check the actual sustained write speeds on any card you buy. The A7IV is power hungry and demands high bitrates for 4K. I would suggest looking into the Lexar Professional 1667x 128GB SDXC UHS-II V60 cards. Theyre way more affordable than V90s and can still handle the 200Mbps recording modes without the buffer choking up. Just make sure to test them before the big day. For power, dont just rely on the camera body for charging. Its slow and adds unnecessary heat to the sensor area. Id grab a Sony BC-QZ1 Battery Charger so you can always have a fresh cell ready in your bag. Also, you might want to consider a high-capacity PD power bank like the Anker 737 Power Bank PowerCore 24K for those long outdoor receptions where you cant find a wall outlet. It supports the Power Delivery spec needed to keep the Sony running while you shoot handheld. Just be careful with your cable management so you dont trip on anything during the dance floor madness...

Keeping it simple is best for weddings. Ive been really satisfied with keeping a physical gear list taped inside my case so I dont forget the tiny things. For $700 you can definitely cover the essentials.

• Sony NP-FZ100 Rechargeable Lithium-Ion Battery
• SanDisk Extreme Pro 128GB UHS-II V90 SDXC Card The V90 speed works well for dual recording. No complaints so far.
