Purchased in 2022. I am selling this because I bought a larger capacity one. I have used it with Canon and OM System cameras. It has always functioned correctly with high-speed continuous shooting at 40 frames per second. It has been formatted, but please initialize it on the device you will be using. Returns are not accepted to prevent swapping. Please understand that this is a used item.
