so I just dropped a ton of cash on a Sony a7R V and now im totally lost with the memory cards. the manual is super confusing and i dont get the difference between the v90 and the cfexpress type a stuff at all. i need something reliable for a wedding shoot im doing in two weeks and honestly my budget is pretty much tapped out after buying the camera. is it actually worth paying double for the sony brand ones or can i get away with a cheaper card? my logic was that since the files are huge i need something really fast but i have no idea where to start looking. help me not mess this up...

@Reply #1 - good point! Reliability is everything for weddings. Honestly, I've had issues with cheaper cards corrupting files, so I dont risk it anymore. The Sony official cards are pricey, but ProGrade really holds up well in my a7R V.
- ProGrade Digital V90 256GB SDXC UHS-II
- Wise Advanced CFexpress Type A 160GB Unfortunately, you really do get what you pay for. Stick to these reliable brands for your shoot.

Regarding what #1 said about reliability, you really cant be too careful with wedding work. I lost half a ceremony once because I skimped on storage, and I still have nightmares about it. Save your footage by sticking to reputable brands that dont fail under pressure.
- SanDisk Extreme Pro 128GB SDXC UHS-II
- Delkin Devices Power 128GB CFexpress Type A Just stick to these and you wont have to stress the shoot.

Congrats on the new gear. Honestly, for a wedding, reliability is way more important than raw speed. I used to cheap out on cards years ago until I had one fail mid-reception and trust me, you never want that pit in your stomach. Since you are budget-tight, dont feel like you need the Sony branded ones. I have been using ProGrade Digital CFexpress Type A Cobalt 320GB for my a1 and they have been flawless over the years. If those are too pricey, grab some Lexar Professional 2000x 128GB SDXC UHS-II V90 cards. They handle the a7R V huge files just fine for most shooting. Just dont skimp on the card reader, get a decent one and you will be golden.

> reliability is way more important than raw speed Like someone mentioned, you really dont want to learn the hard way during a paid wedding gig. I've been shooting these events for years and have seen plenty of pros lose files because they tried to save a few bucks on generic storage. Just catchin up on this thread now, but the consensus is pretty spot on. In my experience, sticking to reputable manufacturers for both your SD and CFexpress media is the only way to sleep at night. I've tried many different setups over the years, and honestly, if you stick to the top-tier lines from Kingston or maybe Angelbird, you wont have those mid-ceremony panic attacks. Don't worry about the premium Sony branding; just pick up a solid, proven brand and focus on your framing instead. Reliability is just non-negotiable when there are no second takes.
