Leave it when the recording is Cinema RAW Light or any mode above 600 Mbps. Relay recording is off during RAW, so a full CFexpress card does not spill RAW onto this SD.<\/p>\n  <p class=\"purchase-links\"><span class=\"amazon-region-btn\">Check Price on <a href=\"https:\/\/www.amazon.com\/s?k=SanDisk+Extreme+PRO+SDXC+UHS-II+128GB&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" rel=\"nofollow noopener\">Amazon US<\/a>, <a href=\"https:\/\/www.amazon.co.uk\/s?k=SanDisk+Extreme+PRO+SDXC+UHS-II+128GB&#038;tag=pctest07-21&#038;linkCode=osi\" target=\"_blank\" rel=\"nofollow noopener\">UK<\/a>, <a href=\"https:\/\/www.amazon.ca\/s?k=SanDisk+Extreme+PRO+SDXC+UHS-II+128GB&#038;tag=pctestt-20&#038;linkCode=osi\" target=\"_blank\" rel=\"nofollow noopener\">CA<\/a>, <a href=\"https:\/\/www.amazon.de\/s?k=SanDisk+Extreme+PRO+SDXC+UHS-II+128GB&#038;tag=67990-21&#038;linkCode=osi\" target=\"_blank\" rel=\"nofollow noopener\">DE<\/a> \u2192<\/span> <a href=\"https:\/\/www.bhphotovideo.com\/c\/search?BI=8941&#038;KBID=10361&#038;SID=12345&#038;DFF=d50&#038;Ntt=SanDisk+Extreme+PRO+SDXC+UHS-II+128GB\" target=\"_blank\" class=\"purchase-link-bh\" rel=\"nofollow noopener\">Check Price on B&#038;H<\/a><\/p>\n<\/div>\n\n<h2>If You Need Something Else<\/h2>\n<p>A 512GB card matches Canon\u2019s published minute table.

Cinema RAW Light HQ at 2420 Mbps, open-gate ST at 1510 Mbps, open-gate LT at 976 Mbps, and XF-HEVC S open-gate Intra at 1350 Mbps all sit above that line.<\/p><\/div>\n  <div class=\"faq-item\"><h3>Whether a V90 SD card records 7K Cinema RAW Light<\/h3><p>It does not. V90 guarantees 90 MB\/s (720 Mbps). Canon still blocks anything above 600 Mbps from the SD slot, and 7K Cinema RAW Light starts at 773 Mbps for full-frame 25p LT and climbs to 2420 Mbps for HQ. The V90 card is for the SD slot: proxies, stills, and video at or below 600 Mbps.<\/p><\/div>\n  <div class=\"faq-item\"><h3>Why VPG400 matters more than a 3700 MB\/s read rating<\/h3><p>HQ RAW needs 302.5 MB\/s of sustained write. VPG400 is a 400 MB\/s minimum. A 3700 MB\/s read number is the card\u2019s peak in a CFexpress 4.0 reader. The C50\u2019s slot is CFexpress 2.0, so the in-camera limit is that bus, and the VPG floor is the figure that has to clear 302.5 MB\/s.<\/p><\/div>\n  <div class=\"faq-item\"><h3>What simultaneous recording and relay recording allow<\/h3><p>Canon enables double-slot simultaneous recording and recording in more than one format at once. Proxy recording is available in XF-AVC, XF-AVC S, and XF-HEVC S, depending on the main format, and is unavailable in slow-and-fast mode above 60 fps. Relay recording is unavailable during RAW, so a full CFexpress card does not continue a RAW clip onto the SD card.<\/p><\/div>\n  <div class=\"faq-item\"><h3>Whether a CFexpress 4.0 Type B card fits the C50<\/h3><p>The CompactFlash Association\u2019s CFexpress 4.0 specification keeps the Type B form factor and backward compatibility with CFexpress 2.0 hosts. A 4.0 Type B card mounts in the C50\u2019s 2.0 slot and records at 2.0 bus speed. The DIAMOND 512GB is already a 2.0 card, which is why it is the default for this body.<\/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>Lexar Professional CFexpress 2.0 Type B DIAMOND 512GB<\/strong> <span class=\"verdict-reason\">\u2013 VPG400 CFexpress 2.0 Type B at the 512GB capacity in Canon\u2019s runtime table.<\/span><\/div>\n      <a href=\"https:\/\/www.amazon.com\/s?k=Lexar+Professional+CFexpress+2.0+Type+B+DIAMOND+512GB&#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>SanDisk Extreme PRO CFexpress 4.0 Type B 256GB<\/strong> <span class=\"verdict-reason\">\u2013 VPG400 at 256GB for shorter RAW takes.<\/span><\/div>\n      <a href=\"https:\/\/www.amazon.com\/s?k=SanDisk+Extreme+PRO+CFexpress+4.0+Type+B+256GB&#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>SanDisk Extreme PRO SDXC UHS-II 128GB<\/strong> <span class=\"verdict-reason\">\u2013 V90 UHS-II for the SD slot, at or below 600 Mbps.<\/span><\/div>\n      <a href=\"https:\/\/www.amazon.com\/s?k=SanDisk+Extreme+PRO+SDXC+UHS-II+128GB&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"verdict-btn\" rel=\"nofollow noopener\">Buy Now<\/a>\n    <\/div>\n  <\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>The EOS C50 records above 600 Mbps on CFexpress 2.0 Type B only.
