I just picked up the Sony a6700 for a wedding I am shooting in San Diego this Saturday and I am honestly panicking a bit about the SD cards. I have been reading up on it and I am seeing such conflicting stuff online. Like some people say you absolutely need V90 cards for anything 10-bit but then I saw a video saying V60 is totally fine for 4K 60p. My logic was that I could save some cash and go with a Lexar V60 but then I got worried because I really want to try out that 4K 120p slow motion and I dont want the camera to just cut out in the middle of a ceremony because the write speed is too slow or something.
I am looking at the ProGrade Gold V60 cards because they are on sale right now but then I read somewhere that the a6700 can be picky with certain brands and might give a card not supported error if the speed isnt consistently high enough for the XAVC S-I format. Is that actually true or just people being extra? I really dont want to spend $200 on a single card if I dont have to especially since I just dropped all my savings on the camera body but I also cant afford to have a card fail during a paid gig. Should I just bite the bullet and get one V90 card for the slow mo stuff and use V60s for the rest or will the V60 handle it all...

Congrats on the new body! The a6700 is seriously amazing for wedding work. So the logic here is actually pretty simple once you check the bitrates... basically you only need V90 if you plan to shoot in XAVC S-I (All-Intra) which is super heavy. If you stick to XAVC HS or XAVC S for that 120p slow motion, a high quality V60 is gonna be totally fine and save you a ton of cash.
- ProGrade Digital SDXC UHS-II Video Speed Class 60 Gold 128GB is a fantastic choice and super reliable.
- Lexar Professional 1800x SDXC UHS-II V60 128GB also works great and is usually a steal.
- Kingston Canvas React Plus V90 128GB if you really want that V90 peace of mind without the Sony price tag. Honestly dont stress too much about the not supported errors, thats usually just from super cheap off-brand stuff. Just grab a few of those ProGrade Digital SDXC UHS-II Video Speed Class 60 Gold 256GB cards and youll be set for the whole day without breaking the bank. Love the setup tho!

Saw this earlier but just now responding. The card not supported thing mostly happens because Sony cameras are programmed to gatekeep specific formats based on the cards V-rating, not the actual speed it hits in a benchmark. If you try to toggle on XAVC S-I (All-Intra), the camera checks the card and if it isnt a V90, it wont let you record. Period. Doesnt matter if its a fast V60. If youre worried about the budget but need that V90 reliability for 4K 120p, look at the Sabrent Rocket V90 256GB SDXC UHS-II. Its usually a lot cheaper than the Sony equivalents and Ive found them to be super stable for high-bitrate video. Another solid choice is the Delkin Devices Power V90 UHS-II SDXC. They have a really good reputation for not overheating, which is a big deal for the a6700 since that body can get pretty warm during long 4K sessions. Honeslty, for a wedding, the V60 cards are totally fine for 90% of what youll do as long as you use XAVC HS. That codec is way more efficient anyway and the file sizes wont kill your hard drive. But if youre dead set on All-Intra for that 120p slow mo, you basically have to get a V90. If it were me, I would grab one high-capacity V90 for the specific slow-mo shots and then use high-quality V60s for the rest of the day to save some cash. Just make sure you test whatever card you buy before Saturday... you dont want to find out a card is a dud while the bride is walking down the aisle.

Been shooting events for years and learned early on that cards arent the place to gamble. I switched to the Sony TOUGH-G series SDXC V90 after a cheap one lagged during a toast once...
- Sony Tough: super reliable, basically indestructible, worth every cent.
- SanDisk Extreme Pro UHS-II V90: slightly more affordable, handles those 120p clips perfectly. Really happy with this setup, zero complaints so far.
