So I finally pulled the trigger on an A7S III because I have a huge wedding shoot this Saturday in Chicago and my old setup just wasnt cutting it anymore. But now Im staring at my screen at 2am losing my mind over SD cards because Sony is so picky about what it actually lets you record. My logic was just to grab whatever had a high number on it but then I started reading about these V60 versus V90 ratings and now Im just paralyzed.
I read online that the Sony Tough G cards are basically the only thing that works 100% of the time for the high bitrate stuff like 4K 120fps but they are like $200 for a single 128GB card which feels like a total scam honestly. I also saw some people recommending the ProGrade Digital V90s as a cheaper alternative but then I saw a couple of reddit threads saying they overheat or get stuck in the slot and now I dont know who to trust. I really need to be able to shoot 10-bit 4:2:2 without the camera just stopping every five minutes because the card cant keep up.
If I go with a V60 card like the SanDisk Extreme Pro is it gonna block me from certain modes? I keep seeing conflicting stuff about XAVC S-I vs XAVC HS. Like if I want to shoot the highest quality slow motion for the ceremony highlights am I forced into buying those expensive Tough cards or even the CFexpress Type A ones? My budget is capped at about $300 for storage right now since I just spent a fortune on the body and a 24-70mm lens and I need at least two cards for redundancy because I cant risk losing someones wedding footage. Is there a specific brand that you guys actually trust for Sony bodies that wont break the bank but also wont fail on me mid-aisle? I literally have three days to get these delivered so I need to make a decision like tonight...

Been thinking about your card situation and honestly, the stress is real when you have a wedding in three days. You might want to consider these points before you hit buy:
- Be careful with the XAVC S-I lockout. If you want to shoot All-Intra for the best editing performance, the A7S III will strictly demand a V90 card. V60 cards like the Sony SF-M Series Tough V60 128GB are incredibly durable and great for the price, but they will limit you to XAVC HS or XAVC S. HS is actually awesome for file sizes but it is much harder on your computer during the edit.
- I would suggest the SanDisk Extreme PRO SDXC UHS-II V90 128GB if you can find them for around $140. They are basically the industry standard for a reason. I have never had one fail on me during a ceremony.
- Another solid choice is the Lexar Professional 2000x SDXC UHS-II V90 128GB. They usually come with a little SD reader too, which is a nice bonus. Make sure to format whatever cards you get inside the camera itself as soon as they arrive. Dont just start shooting. I would avoid the cheaper V60 cards for a wedding... the risk of a write-speed error mid-vow just isnt worth the $50 you would save. Good luck with the Chicago shoot, you're gonna love that camera!

I've shot dozens of events with the A7S III and honestly, you need V90s to avoid those annoying lockouts in S-I mode. Over the years I've found these are the most reliable without the Sony tax:
- ProGrade Digital SDXC UHS-II V90 128GB
- Kingston Canvas React Plus 128GB SDXC UHS-II The Kingstons are usually a steal and haven't failed me once. V60 cards will definitely block you from the high-bitrate S-I modes you'll want for the ceremony.
