Best Memory Cards for Sony FX6
Looking for the best memory cards for Sony FX6? Here are our top recommended & fastest CFexpress cards and SD cards for Sony FX6 full-frame cinema camera.
The Sony FX6 has dual memory card slots that are both compatible with CFexpress Type A cards and UHS-II-compatible SD cards. With the ability to capture up to 15+ stops of dynamic range, Sony’s S-Cinetone gamma for filmlike skin tones, and up to 10-bit, 4:2:2 XAVC-I recording, the Sony FX6 is poised to both supplement your FX9 or VENICE capture and to nimbly take on documentary, gimbal, and drone shoots on its own. The Sony FX6 camera combines a 4K full-frame Exmor R sensor with a BIONX XR engine for extremely sensitive capture in a range of settings using a base ISO of 800 as well as an ISO 12800 high-sensitivity mode for nuanced low-light scenes.
As we mentioned above, the Sony FX6 (B&H, Adorama) has 2x memory card slots that both support CFexpress Type A cards and UHS-II SD cards. Although SD cards and CFexpress Type A cards are not the same in size, both card slots in the Sony FX6 will accept either card type. So, if you have already had some fast SD cards, you can continue to use them since most of the Sony FX6’s features work fine with either V60 or V90 cards. But, if you would like to use the camera’s most bandwidth intensive recording format – 10-bit, 4:2:2 XAVC-I recording, you will still need some higher-performance CFexpress Type A cards. So, in order to get the ultra high read speeds (transfer speed) and write speeds (fast buffer clearing time) to get the best out of your Sony FX6 camera, here we list the top recommended & fastest CFexpress Type A cards and SD cards for the Sony FX6 cinema camera based on the speed and price. Just choose the one you like.
