The most recent Sony full-frame mirrorless cameras have two memory card slots. This allows you to set up your cards in various ways. For example you can have your Sony A7 III write to both cards, or use slot 2 to record just certain types of files.
In this article, I’m going to guide you through all the settings, what they mean and how to configure the Sony A7 series dual card slot. If you want to know which cards I recommend for your A7 / A9 model, check out our dedicated article below.
When you turn on your Sony A7 camera for the first time, you’ll notice that there is an extensive and somewhat confusing menu system with multiple pages and some terminology that isn’t easy to understand at first.

In this article, I’m going to guide you through some useful tips and explain how to customise the camera so that accessing your favourite functions becomes much less of a hassle.
