Angelbird CFexpress B SX 330GB | 1785MB/s | Pro Camera Card

The Problem: Missed Moments, Dropped Frames, and Workflow Risk

Today’s high-performance cameras—like the Canon EOS R5, Nikon Z9, and Canon C500 Mark II—produce breathtaking 4K/8K video and ultra-fast burst photos. But if your memory card can’t keep up, the result is dropped frames, buffer lags, and lost content in high-pressure environments.

Generic cards aren't built for this.

Engineered specifically for demanding photography and video production, the AV PRO CFexpress B SX is built to match your camera’s capabilities—without compromise. With Stable Stream™ technology, you get uninterrupted recording performance through the full 330GB capacity, ensuring every frame and every shot counts.
