    MC-CF660G CF Express Memory Card

    Posted by Ron Calverley on January 30, 2023

    Although quite pricy, this card does work as advertised. I was having problems in the past when using an unapproved brand, in that the other brand eventually stopped recording when in N-Raw/8K/60 setting. So far my mew new MC-CF660G memory card is working flawlessly --- so far! This 660g size is a bones too. This was shot using my Z9 with the new MC-CF660G card.

    MC-CF660G CFexpress Memory Card

    I just got two of these for use in my Z9. I had a pair of 256 Gig cards from another manufacturer but only got 12 minutes in 8K 24fps N-Log for each one. It wouldn't have bee so bad if the Z9 automatically switched to card #2 for overfill, but it doesn't in video. . These give me just over 30 minutes each. They work as they should. A test recording in 8K 24fps for 20 minutes without any problem hopefully indicates these will fit the bill. Now if Nikon can do a FW update to allow the Z9 to switch to Slot 2 while recording, even if it has to start a new file with a few seconds of overlap, it would top up the perfection of the camera.
