Finally: First 4.0 CFexpress Type A card from OWC now in Stock at Amazon US!

Finally the very first new 4.0 generation CFexpress Type A cards are in Stock at Amazon US! Those are the options:

• 480GB for $319
• 960GB for $519

They are available for preorder but not in Stock at BHphoto, Adorama.

Why buy such cards?

No Sony camera yet has the hardware to support these Generation 4.0 cards. But there are three good reasons why to buy them anyway:

1. Those cards are backwards compatible and will work just fine on any Alpha camera on their max speed possible (900MB/s)
2. When you download the file to your computer it will be running at max speed of 1620MB/s Write via the new 4.0 card readers
3. I suspect that future cameras like the Sony A1II and Sony A7V will support those cards. So if you buy those cards now you are future proof if you switch to a future new Sony camera!
