Frequently Asked Questions

What makes CFexpress Type A different from Type B?

Type A is smaller (38.5 x 29.8mm vs 160 x 107mm) and exclusive to Sony cameras. Type A reaches 800 MB/s vs Type B at 1250 MB/s. Only Sony cinema cameras (A7S III, FX3) use Type A.

Can I use the Sony MRW-G2 with Canon R5 or Nikon Z9?

No. The MRW-G2 only reads CFexpress Type A and SD UHS-II. Canon and Nikon cinema cameras use CFexpress Type B (not Type A). Use ProGrade PG05.5 for Canon/Nikon.

How much faster is Type A CFexpress vs SD for 4K 120fps?

Type A reaches 800 MB/s vs SD at 312 MB/s. For 4K 120fps RAW on Sony FX3 (2.6 Gbps bitrate), Type A speed is essential. SD cards will buffer or drop frames.

Is the Sony MRW-G2 the official Sony card reader?

Yes, officially recommended by Sony for A7S III, FX3, A1, A7 IV, and FX6. Sold by Sony and authorized retailers. Ensures compatibility and optimal performance.
