Best Memory Cards Sony A7cr

The A7cr takes Sony’s 61MP resolution sensor and puts it in the smallest full-frame body they make — single UHS-II SD slot, no CFexpress. It shares the same codecs as the A7R V (600Mbps H.264 All-I, 200Mbps H.265, S&Q slow-motion modes) and the same sensor, but routes everything through one card slot. V60 covers H.265 and general shooting. V90 is required for 600Mbps H.264 All-I and S&Q. At 8fps with 61MP files, the buffer fills fast — V90 clears it meaningfully faster.

UHS-II V90 cards are the best SD cards for the Sony A7cr. They allow you to shoot a maximum bitrate of the older H.264 codec, which is 600Mbps, and the v90 cards also allow you to use all of the different S&Q slow-motion settings. Photographers shooting continuous bursts will also want to use the v90 cards to clear the buffer as quickly as possible since this camera will allow for 8fps bursts.

For bitrates of 480Mbps or lower, when using the more efficient H.265 HEVC codec, V60 cards are a great option since they offer significant cost savings. This is especially beneficial when using Sony’s efficient H.265 codec labeled XAVC HS.

Recommended SD Cards For Sony A7cr

Below, you’ll find recommendations for the best SD cards for the Sony A7cr. I’ve included V90 and V60 cards since V60s are recommended for casual shooting and not using many high-end video features like S&Q, aka landscape photographers.

These recommendations come from testing all the different memory cards in other Sony cameras. Since the Sony A7cr is a baby A7rV, you can compare cards with this Sony A7rV memory card chart to see the in-camera benchmarks.

Does The Sony A7cr Support CFexpress Type A Cards?

No, the Sony A7cr is only compatible with SD cards, including UHS-I and UHS-II cards up to the v90 speed class.

Sony A7cr Capacity

What’s the upper limit on SD card capacity for the Sony A7cr?

Sony doesn’t explicitly state the maximum capacity for the A7cr. Nonetheless, it’s generally observed that these newer Sony cameras don’t have specific restrictions on memory card sizes, so using cards up to 2TB should work without any issues.

Sony A7cr What Size Card To Buy?

A 128 GB card would be a good starting point if you’re primarily into photography and videography. However, if you focus on high-bitrate video, you might consider upgrading to a 256GB card.

In-Camera Benchmark Results

The A7cr uses the same 61MP sensor and BIONZ XR processor as the Sony A7R V. The speeds below are from direct in-camera testing in the A7R V’s SD slot — the closest available data to what the A7cr should produce given identical sensor and processor architecture.

What the Speed Numbers Mean

These speeds are measured across the full burst sequence — from first frame through the last frame written after the buffer drains. The A7cr shoots at 8fps with 61MP RAW files, so the buffer fills quickly. V90 cards at 200+ MB/s recover meaningfully faster than V60 options for burst shooting. For video, 600 Mbps H.264 recording requires 75 MB/s sustained — only V90 covers this comfortably. V60 handles everything up to the 280 Mbps H.265 modes (35 MB/s) without issue.

Sony A7cr Memory Cards — FAQ

Does the Sony A7cr support CFexpress Type A?

No. The A7cr has a single UHS-II SD slot only — no CFexpress. Sony positioned this as the compact counterpart to the A7R V, and the trade-off for the smaller body is one slot and no CFxA support. If you need CFexpress, the A7R V is the body to buy.

Can I use the same cards in the A7cr and the A7R V?

Yes. The A7cr’s single slot accepts the same UHS-II SD cards that work in the A7R V’s SD slots. The benchmark data on this page is derived from A7R V testing since both cameras share the same 61MP sensor and BIONZ XR processor — the in-camera write speeds translate directly. If you already have V90 cards for an A7R V, they’ll work in the A7cr at the same speed.

Do I need V90 for the A7cr, or will V60 work?

Depends on what you shoot. V60 handles all H.265 HEVC recording (up to 480Mbps) and general stills without issue. V90 is required for 600Mbps H.264 All-I and S&Q slow-motion modes. For landscape and portrait work, V60 is perfectly adequate. For wildlife or sports at 8fps with 61MP files, V90 gives you faster buffer recovery between sequences.

Does the A7cr’s single slot limit its performance compared to the A7R V?

For most shooting, no. A single fast V90 card handles everything the A7cr can do. The limitation is redundancy: you can’t run simultaneous backup mode like you can on the A7R V’s dual slots. If backup recording is important to your workflow — wedding photographers especially — the single slot is a real constraint to factor into the buying decision.
