Honestly, you dont need v90 for most wedding stuff on the a7iv. In my experience, ProGrade Digital SDXC UHS-II V60 Gold 128GB cards handle 4k 10-bit video perfectly without any buffering issues. Unless youre doing high-frame rate slow mo, v60 is the sweet spot. You can grab two within your budget and actually have redundancy, which is way more important for a wedding gig anyway.

To add to the point above: it really seems like the consensus here is that v60 cards are the safest bet to stay under that 150 limit. Since youre doing a wedding, redundancy is basically the most important thing to keep you from panicking mid-ceremony. Heres a couple ways to handle the budget and stay safe:

• Grab two SanDisk Extreme Pro 128GB SDXC UHS-II V60 cards. You can set the a7iv to record to both slots simultaneously so if one card fails, you still have the footage.
• If you really want v90 for peace of mind, the Kingston Canvas React Plus 128GB SDXC UHS-II V90 is usually way cheaper than the Sony ones and performs really well for the price.
• Stick to standard 4k 24p or 60p and youll be totally fine without any buffering issues. Just make sure you test the cards a few times before the big day in Brooklyn. You got this.

What exact bitrates are you shooting? I've been really happy with Sony TOUGH-M Series SDXC UHS-II 128GB for years; they've survived heavy 10-bit wedding days without failing or hitting any buffers, tbh.

The fastest and most reliable cards are the ones that can actually sustain their rated speed without overheating, but unfortunately, many of them are not as good as expected under heavy 10-bit loads. It's really frustrating. This actually reminds me of when my mentor had a massive ordeal with his gear at a high-stakes event. He had these top-of-the-line cards, but they just couldnt handle the constant stream and started throwing write errors right during the vows. We spent the whole reception trying to recover the footage on a tiny laptop in the kitchen... it was a total mess and honestly, the specs on the box didnt mean anything in that moment. It just goes to show how unpredictable things can be when you're pushing the hardware. You're gonna do great with the gig though, just trust your gut!

I've had my share of scares with the a7iv and card speeds, so I'm pretty conservative now. My biggest takeaway from doing weddings is that consistency between the two slots is everything. I once made the mistake of using a faster card in slot one and a slower backup in slot two, thinking it wouldnt matter, but the camera ended up bottlenecking at the slower write speed anyway. My routine for reliability usually looks like this:

• Running a full data stress test on any new card before it ever sees a wedding.
• Sticking to identical cards for both slots so the buffer clears at the same rate.
• Watching out for heat issues during long, continuous takes like the vows or speeches. I've seen cards that supposedly met all the specs fail after twenty minutes of constant 4k 10-bit recording because they just got too hot. It makes me very wary of just looking at the labels on the front. I'd suggest being very careful and maybe testing your current setup in a room that isnt air-conditioned to see how it handles the heat before your Brooklyn gig... better to find the breaking point now than mid-ceremony.

Same here!
