Best Memory Cards for Sony FX3

Looking for the best memory cards for Sony FX3? Here are our top recommended & fastest CFexpress cards and SD cards for Sony FX3 cinema camera.

The Sony FX3 has dual memory card slots that both accept either CFexpress cards (Type A) or UHS-II SD cards. The Sony FX3 is Sony’s most compact and lightweight Cinema Line camera that is ideal for handheld shooting, gimbal and drone-mounted work, and it bridges the gap between the portability of the a7S III and the capability of the FX6. It’s built around the same 12MP full-frame BSI-CMOS sensor as the a7S III and promises the same UHD 4K capabilities, including UHD 4K at up to 60p from the full 4.2K pixel width of its sensor and 4K/120p with a slight crop. All these options can be captured as 10-bit 4:2:2 video, with a choice of the XAVC HS (H.265), XAVC S (H.264) or XAVC S-I (All-I H.264). Like the a7S III, the Sony FX3 (AmazonB&HAdorama) can output 16-bit Raw video data over its full-size HDMI port. An expanded ISO range of 80 to 409,600, over 15 stops of dynamic range, and limited rolling shutter effects further complement the FX3’s sensitive, nuanced image capture. As the latest addition to Sony’s Cinema Line, the Sony FX3 delivers a cinematic look and professional operability and reliability in a camera that is accessible to early-career creators, as well as suitable to be used alongside Sony’s VENICE, FX9 and FX6 cameras.

As we mentioned above, the Sony FX3 has 2x memory card slots that both support CFexpress Type A cards and UHS-II SD cards. Although the CFexpress cards (Type A) and the SD cards are not the same in size, both card slots in the Sony FX3 will accept either card type. 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 FX3, here we list the top recommended & fastest CFexpress cards (Type A) and SD cards for the Sony FX3 cinema camera based on the speed and price.
