Frequently Asked Questions

What SD Card Do I Need for Sony A7 IV?
The Sony A7 IV requires a CFexpress Type A or SD UHS-II card with V60 (V90 for S&Q modes) speed rating for reliable performance. We recommend 256GB capacity as the sweet spot balancing storage capacity with affordability. The device supports up to No official limit, though most users find 256GB sufficient for daily use. Always choose from trusted brands like SanDisk, Lexar, or Kingston to ensure consistent performance and avoid data loss.
Do I need a CFexpress Type A card for the Sony A7 IV?
No, it's not required for most shooting. A V60 or V90 SD UHS-II card is sufficient for almost all video modes. CFexpress Type A is only necessary for clearing the buffer faster during intense burst photography or for the absolute highest video bitrates.
What is the difference between the two card slots?
Slot 1 is a combo slot that fits either one CFexpress Type A card or one SD card (UHS-I/II). Slot 2 only fits one SD card (UHS-I/II). You can use both for simultaneous backup or relay recording.

Can I use older or slower cards with Sony A7 IV?

Do I need a UHS card for Sony A7 IV?
UHS cards are recommended for best performance with Sony A7 IV. Non-UHS cards will work but may have slower transfer speeds. For this device, UHS-II is optimal.
Should I use more than one card with Sony A7 IV?
For professional use or extended shooting sessions, dual cards provide redundancy and backup. Using multiple cards ensures you won't lose footage if one card fails. This is especially important for valuable recordings.
