Exascend Essential CFexpress Type A Memory Card

The Essential CFexpress Type A is Exascend's Type A card, the small form factor used by Sony cinema and mirrorless bodies that take CFexpress Type A alongside SD. Type A trades the raw bandwidth of Type B for a slot that also accepts an SD card, which is what makes dual-format bodies practical.

It is offered from 120GB through 1TB. Choose the capacity against the codec and the shoot length rather than against the headline speed, since Type A cards are usually the constraint on continuous recording rather than on burst stills.
