Next week Delkin will announce new Black Series CFexpress memory cards that can write faster than the Nikon Z9 stated camera minimums in the Z9 manual: “Instead of 79 Frames NEF (RAW), lossless compression, the card can write until full, without using the buffer“:
Delkin currently has several lower-capacity Black Series CFexpress memory cards (Delkin CFExpress cards are sold at Adorama, Amazon, and B&H).
Update – the new cards are already listed for sale at B&H Photo:
