Sony M Series SDXC UHS-II Card 64GB, V60, CL10, U3, Max R277MB/S, W150MB/S (SF-M64/T2), Black

Good

I had a 32GB sd card. Not enough space. Bought this one and now I have enough space to photograph an entire wedding plus take some video

Very fast and reliable memory card used in my A7RII.

Works well so far, no complaints. Have not tested the actual speed, but both the package and the card sticker now claim 150MB write speed.

Good! Works well with my mirrorless photo and video. Sony A7r mark ii and Sony A7s Mark ii

Good price at decent speed. Not the fastest but fast enough.

Works great. Fast read and writing.

No problem with this in my Sony a7III.

You really have no choice if you are using the Z7. This Memory Card works perfectly, is well made, fast and easy to handle. It takes a special USB reader to connect to your computer. So the entire package is a bit expensive. But considering the investment in camera equipment and the value of getting the shot, its really not that big of an expense.

So I recently purchased two 64GB cards. According to Sonys recall notice, if your card does not have an * in the back, then it is affected. Of the two cards I purchased, one has the * and the other does not. Like the comments of another user on this page, Sony may be overwhelmed by calls and due to the COVID-19 situation, replacement will be staggered. In my case, it will cost me to ship the card out of my country and I will have to pay customs duty when the replacement gets here which ultimately is costing me more for shipment than the actual cost of the card. TBH, I have done some 4k tests shots on the affected card and it works fine so I am not sure if this is a potential risk or an inevitable risk. Only time will tell.
