Lexar 512GB CFexpre Type B Reviews
Lexar is my choice
By William
Rated 5 out of 5

This card is faster than my new Canon R6 Mark III can use but I could not pass up the deal pricing. I have used Lexar cards for decades and only had one Lexar 128GB Professional 1667x SD Card, UHS-II, C10, U3, V60 just recently. The deal and shipment from B&H was very good. I hope the price of a second one will go down, but am not holding my breath with the pressure on pricing of all memory related items lately.
The best.
