Choosing the Right SD Card for Sony Alpha 7 IV

The selection of a memory card must meet several essential criteria. First of all, storage capacity is a key element. If you’re shooting in 4K or shooting in RAW format, the files generated can be very large. A 128GB card may be enough for short sessions, but it’s often better to opt for a 256GB or 512GB card to avoid frequent interruptions.

Write speed is another factor to consider, especially for high-definition video and burst shooting. A V60 or V90 class card is highly recommended to ensure optimal fluidity. As the Sony Alpha 7 IV is compatible with UHS-II, it is preferable to favor this type of bus, which allows much higher transfer speeds than UHS-I.

Finally, robustness and reliability are essential. Some SD cards are designed to withstand water, extreme temperatures, and shocks. Opting for a quality card helps avoid any unpleasant surprises and guarantees the security of your files.
