The CFexpress memory card type is a new generation storage media for professional photographers. It is designed specifically with DSLR cameras in mind, offering incredibly fast speeds and huge capacities. CFexpress is an evolution of XQD and CF cards, although the interface types do not directly replace each other. When selecting a DSLR camera it is important to look out for the type of memory card required, as these memory card types are not always interchangeable.
Available in a range of capacities, with the smallest starting around 64GB, it is expected that CFexpress cards will be available in 2TB or even 4TB versions in the near future.
This is an ultra-reliable storage type, which is why it has become a popular choice with professional photographers.
