Nikon will update SLR firmware to be compatible with CFexpress Type B card
Nikon will update the firmware of D5, D850 and D500 three SLR cameras within this year to be compatible with the new CFexpress Type B memory card.
As early as February 2019, Nikon announced that it was developing new firmware for D5, D850 and D500 digital SLR cameras to be compatible with CFExpress Type B memory cards. D5, D850 and D500 are Nikon mid-to-high-end SLR digital cameras. D5 provides dual XQD and dual CF card slot versions. D850 and D500 are single SD card slot + single XQD card slot. Due to the CFExpress Type B shape, size, pins and XQD It is exactly the same, but also uses the PCIE transmission protocol, so the XQD card slot is theoretically compatible with CFExpress Type B. According to nikonrumors, Nikon will announce three new SLR camera firmware updates when the two new cameras Z6 II and Z7 II are released.
Compared with XQD cards, CFexpress Type B is faster and has a larger capacity, and is supported by many memory card brands. At present, more than 10 brands have launched CFexpress Type B, with a maximum capacity of 2TB. However, for D5, D850 and D500 users, the greatest significance of supporting CFexpress Type B may be to use a cheap domestic CFexpress Type B Zhai card to enjoy a high-speed reading and writing experience of less than 1TB and less than 500$
