After this card has become priced lower, it is the 2nd Lexar 800x Prof CF card, which I bought for use in the D800. I've been very pleased with the first. The card is recognized without difficulty, is lightning fast, so they do not thwarting the continuous shooting mode of the D800 (with attached MFG) and transfers the photos with the Lexar Multi-Card 25-in-1 USB 3.0 memory card reader also fast on the computer. In addition, since lifetime warranty in Germany (idiotically) is not allowed, a 10-year warranty. I can not imagine a better card for a high-performance camera like the D800.
