    SD card compatibility and requirements for Sony A7R IV<\/h2>\n\n

    The Sony a7R IV, with its 61-megapixel sensor and 4K video, generates 123MB RAW files. Choosing the right SD card is crucial<\/strong> for managing these large files without compromising burst shooting or video quality.<\/p>\n\n

    Both slots accept UHS-I and UHS-II cards, but the latter offer speeds of up to 300 MB\/s compared to 100 MB\/s<\/strong> . SDXC cards (64 GB+) prevent 4K video fragmentation thanks to their 64-bit format. For video, a minimum V30 rating is sufficient, but V60\/V90 provides increased security. <\/p>\n\n

    Write speeds and buffer management<\/h3>\n\n

    The Sony a7R IVA’s uncompressed RAW files are 123MB each. The 4GB buffer allows for 31 images before filling up. Without a fast UHS-II card, the buffer empties slowly, slowing down the burst rate.<\/strong> <\/p>\n\n

    Let’s be honest, UHS-II cards are worth the price. For 31 RAW images, the buffer empties in 18-19 seconds compared to 44 seconds with a UHS-I. So, if you plan on shooting continuous bursts, UHS-II cards are essential<\/strong> . <\/p>\n\n

    Requirements for 4K video recording<\/h3>\n\n

    The Sony a7R IVA records in 4K at 100 Mbps (12.5 MB\/s). While V30\/U3 class cards are sufficient, UHS-II cards offer added security. For what ? Because SDXC cards avoid video fragmentation<\/strong> into 4GB segments.<\/p>\n\n
