Introducing one of Angelbird's first 4.0 Type A CFexpress™ cards, the 512GB AVP512CFXAMK2 features maximum read/write speeds of 1800 and 1650 MB/s, respectively—both higher than their own 2.0 Type B cards! These speeds are kept consistent and uninterrupted with Angelbird's Stable Stream™ technology. The 4.0 Type A features advanced thermal management to protect itself from overheating, and draws as little power as possible to keep your camera's battery alive for as long as you need it. While optimized for Sony cameras, this card is perfect for video and photo enthusiasts of all kinds, and best for capturing cinema-grade video and extended burst photography in up to 8K+ RAW.
