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

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.

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.

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

Great product very fast transfer speeds

Works great. Fast read and writing.

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

Super fast cards. Fast shipping

I bought 2 of these cards and theyve performed flawlessly in my Sony a7RIII for both photos and 4K video. Expensive, but worth it.

Good

Its a good and quality product, thanks Sony! /Before that I was using these ones: SanDisk 64GB Extreme PRO SDXC UHS-I Memory Card (SDSDXXG-064G-GN4IN) ---- NEVER BUY THEM!!!!! THEY ARE MADE OF VERY CHEAP PLASTIC!!! ONE RUINED MY Sony A7rII SD- card slot!!!. /. This Sony card is very good! Highly recommended!!!
