Lexar 160GB Professional CFexpress Type A Gold Series Memory Card, Up to 900MB/s Read, Cinema-Quality 8K Video, Rated VPG 400 (LCAGOLD160G-RNENG)

The Nikon D850 camera was designed to use Nikon or Sony XQD memory cards, but these cards are very limited in availability, size, and price. I recently discovered that a CFexpress "Type B" memory card should work in my camera with the latest firmware update, so I purchased this CFexpress Type B memory card to see if that is true. I updated the firmware for the camera, installed the memory card, and formatted the card in the camera, and, as advertised, it works!However, according to Nikon, the read and write speed will be limited to a lower speed than what the card is capable of due to the camera's data handling to accommodate the CFexpress Type B Memory Card. However, it is still fast enough to see no difference from using the XQD card.I am glad I can use a CFexpress Type B Memory Card because it is cheaper than XQD cards and has more memory capacity options.

As far as my experience goes, these are the best cards to buy if you're using a Sony camera. They are reliable and fast. First instance I thought "why bother with these", SD cards are fine. That was, until I made the switch and noticed a read-out speed that is quicker then you can fill the camera's buffer. Even for me, as a hobby photographer, this is an absolute must when taking wild life or bird photo's.

This card is a photographer & videographer’s dream come true. Performs amazing and the quality of the media is superb. Video media is the quality any person who wants clarity in their work would want to have.

This is a high performance, low cost CF Express type A memory card. It's fast enough to handle the most demanding video, and highest frame rate image file settings on my Sony A1 camera.

So far, so good. I have recorded the same codec and frame rates as I did with my Sony Tough Cfast Express A. It is good bang for the buck and has performed well on quite a few paid jobs.

Great quality and fast.

The first one I ordered came missing from the package. (Amazon really needs to dial in the security) They sent the replacement right away and I am good to go.

Update:I figured a way to make this card not get stuck in camera. Sharing so it may help someone else in similar situation. The card gets stuck due to the shape of one of the two notches on either side. In order to get the card out I cut a thin 3 inch long strip of hard yet flexible plastic (taken packaging). With the card inserted/stuck you can still insert this strip from the stuck side until it goes beyond the notch and release the card. To fix this issue I cut a very small piece of the notch. Now it does not get stuck. Since my problem is solved and that I had bought is on sale I kept the card. I also upped one star.Lexar- fix this. It’s such a small thing.Original:I already have a card from another brand which sits and ejects fine. However this card gets stuck every time I insert it. One of the notches on right side is the cause. I have to insert a strip of thin plastic in order to get it out. It is also slightly tight (does not click) when inserted. It records photos and video fine but It’s going back.Lexar if you see this and have a fix please do share.
