Best Memory Cards Sony A7c

The Sony A7c uses a single UHS-II memory card of any size. Here is a quick list of the best SD cards for the Sony A7c, with a few great options. You most likely don’t need the fastest SD cards.

Sony A7c Recommended Memory Cards

You should decide between three categories of SD memory cards: fast v90 UHS-II cards, v60 UHS-II cards, and U3 UHS-I cards.

V90 UHS-II cards are the fastest memory cards for the Sony a7c. They are great for photographers who do a lot of continuous bursting but are overkill for everything else.

V60 UHS-II cards are perfect for photographers who occasionally burst but mostly shoot in single-shot mode. They’re also great for video shooters because they allow you to transfer large files quickly to your computer.

v30 UHS-I cards are fine for casual photographers and video shooters. These are great for photographers who want large cards at a reasonable price.

Here are the top cards for each speed class.

Do You Need UHS-II Memory Cards?

UHS-II cards come in three speed classes: U3, V60, and V90. These numbers represent the minimum write speed of the card. V90 can maintain a minimum of 90MB/s, V60 cards 60MB/s, and U3 30MB/s.

You should choose one of these cards depending on the price, how much money you’re willing to spend, and the performance you need. Casual shooters might just like V60 cards. They can buy a bigger card for the same price and probably never notice the speed difference. Sports shooters who do a lot of continuous bursting would benefit from a V90 card.

Videographers and vloggers only need U3 cards, allowing you to buy much larger cards to store all that video.

What Size Memory Card Is Best For The Sony A7c?

The best-sized memory card is going to be different for everyone.

64GB – If you’re just shooting JPG and not a lot of video, a 64GB card will be fine.

128GB—If you shoot RAW and video occasionally, I’d start with a 128GB card.

256GB—You most likely won’t need a bigger card than 128GB unless you shoot a lot of video and don’t clear off the card regularly or you’re traveling and are not bringing a computer.

Best Memory Cards For 4k Video

Although 4 K video seems like a lot of data, the video bitrate is only 100 Mbps, translating to a 12.5MB/s data stream.

A U3-rated card can maintain a minimum stream of 30MB/s, so all you’ll need for a 4k video is a U3 UHS-I card.

You do not need a UHS-II card for 4 K video, but they are great for transferring data from the card to a computer with a UHS-II memory card reader, since this transfer speed can be significantly faster.
