S-I 4K is 600 Mbps and Sony prints <strong>SDXC V90<\/strong>. This body has one slot, so the default card unlocks every Rec Format. SF-M V60 is Budget for people who never open S-I.<\/p><\/div>\n  <div class=\"faq-item\"><h3>Whether a UHS-I card works in the a7C II<\/h3><p>Yes. The slot is UHS-I\/II. Stills and U3 Long GOP 4K will record. Buffer clear and offload run at UHS-I. Proxy 4K and S&#038;Q 4K need V60. S-I needs V90. a UHS-I V30 is a stills\/JPEG card, not the hybrid default.<\/p><\/div>\n  <div class=\"faq-item\"><h3>How one slot differs from the A7 IV<\/h3><p>A7 IV has CFexpress Type A + SD. This camera does not. A failed or full card ends the take. 256 GB is the practical size; two 128 GB cards are a swap workflow, not overflow. A7 IV SD guide: <a href=\"https:\/\/www.cameraegg.org\/camerareview\/best-sd-memory-card-for-sony-a7iv\/\">Best SD Memory Card for Sony A7 IV<\/a>.<\/p><\/div>\n  <div class=\"faq-item\"><h3>Whether 4K 60p is full-frame on this body<\/h3><p>No. Sony: 4K 60\/50p is Super 35 only. Full-frame 4K on the a7C II is 24\/30p (and the HS 24p rows). Card speed does not restore a full-frame 60p mode.<\/p><\/div>\n  <div class=\"faq-item\"><h3>What SDHC does to long movie clips<\/h3><p>Sony: movies on SDHC split at 4 GB. Time-lapse stops before that split. Use SDXC (64 GB and up) for anything longer than a short clip. Format the card in the camera.<\/p><\/div>\n<\/div>\n\n<h2>Final Verdict<\/h2>\n<div class=\"conclusion-module verdict-box\">\n  <div class=\"verdict-picks\">\n  <div class=\"verdict-item\">\n  <span class=\"verdict-label\">\ud83c\udfc6 Best Overall:<\/span>\n  <div class=\"verdict-product\"><strong>Sony SF-G Tough V90<\/strong> <span class=\"verdict-reason\">\u2013 V90 for S-I 4K 600 Mbps; 256 GB TOUGH for the only slot.<\/span><\/div>\n  <a href=\"https:\/\/www.amazon.com\/s?k=Sony+SF-G+Tough&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"verdict-btn\" rel=\"nofollow noopener\">Buy Now<\/a>\n  <\/div>\n  <div class=\"verdict-item\">\n  <span class=\"verdict-label\">\ud83d\udc8e Best Value:<\/span>\n  <div class=\"verdict-product\"><strong>Kingston Canvas React Plus<\/strong> <span class=\"verdict-reason\">\u2013 Same V90 class at 300\/260 MB\/s.<\/span><\/div>\n  <a href=\"https:\/\/www.amazon.com\/s?k=Kingston+Canvas+React+Plus&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"verdict-btn\" rel=\"nofollow noopener\">Buy Now<\/a>\n  <\/div>\n  <div class=\"verdict-item\">\n  <span class=\"verdict-label\">\ud83d\udcb0 Budget Pick:<\/span>\n  <div class=\"verdict-product\"><strong>Sony SF-M Series V60<\/strong> <span class=\"verdict-reason\">\u2013 Long GOP 4K, proxy, and S&#038;Q.
